Abstract:

In the 1950s, exotica was a genre of pop music that specialized in depicting imaginary exotic paradises and conventionalized natives. By the late 1960s, exotica pop had disappeared, but its tropes of temporal and spatial disjuncture persisted, structuring the music, visual art, and social theory of the utopian counterculture. While 1950s and 1960s kinds of exotica differ in their preferred imaginary destinations, both raise the question of what intermediate shades between belief and disbelief are demanded by aestheticized representations of human life. This essay theorizes exotica as a mode of representation governed by a peculiar mode of reception——one of willed credulity enabled by submission to its spectacle. What exotica demands is what intellectuals are least likely to give, though, and the peculiar pleasures of exotica spectacle are denigrated or rendered invisible in the hermeneutic regime.

Abstract:

Invasions by exotic plants may be more likely if exotics have low rates of attack by natural enemies, including post-dispersal seed predators (granivores). We investigated this idea with a field experiment conducted near Newmarket, Ontario, in which we experimentally excluded vertebrate and terrestrial insect seed predators from seeds of 43 native and exotic old-field plants. Protection from vertebrates significantly increased recovery of seeds; vertebrate exclusion produced higher recovery than controls for 30 of the experimental species, increasing overall seed recovery from 38.2 to 45.6%. Losses to vertebrates varied among species, significantly increasing with seed mass. In contrast, insect exclusion did not significantly improve seed recovery. There was no evidence that aliens benefitted from a reduced rate of post-dispersal seed predation. The impacts of seed predators did not differ significantly between natives and exotics, which instead showed very similar responses to predator exclusion treatments. These results indicate that while vertebrate granivores had important impacts, especially on large-seeded species, exotics did not generally benefit from reduced rates of seed predation. Instead, differences between natives and exotics were small compared with interspecific variation within these groups.Key words: aliens, exotics, granivores, invaders, old fields, seed predators.

Full text

Abstract:

At least 16 species of Australian mammals have become extinct over the past 200 years. Without islands, however, this figure would be even worse as nine species that were formerly widespread on mainland Australia were or are restricted to land-bridge islands. In addition, 13 species and subspecies of endangered and vulnerable mainland mammals that still occur on the mainland have island populations, reducing their chance of extinction. In all, 43 islands protect 29 taxa of Australian threatened mammals. Since European settlement some island mammal populations have become extinct, while many new populations, of both Australian and exotic mammals, have been established. The extinction of island native mammal populations is significantly correlated with the introduction of exotic mammals. Management of islands needs to concentrate on four areas: quarantine, monitoring (of both native mammals and possible introduction of exotics), eradication of exotics and translocations of native species. Prevention of introduction and establishment of further exotics to important islands through quarantine procedures is vital, especially for islands with permanent or temporary human habitation. Eradication or control of existing exotics is required for many islands and eradication of further introductions, as soon after detection as possible, should be a high priority action for nature conservation agencies. Past exotic mammal eradications and needs for the future are discussed. Translocations of island mammal populations to the mainland should take place only where the species is extinct on the mainland. Translocation to islands, where translocation to or on the mainland is not feasible, is an important conservation technique. Islands with exotics can be of value for re-introduction of locally extinct mammals or introductions (marooning) of threatened species that are at risk from feral predators on the mainland once the exotics have been eliminated.

Abstract:

The primary objective of the first year of the project was to determine the number and distribution of exotic plant species within the park. A preliminary list of exotics was provided by park personal. A more complete list of exotics found in the park was then generated using Heidel's (1990) list of "Preliminary Vascular Flora of Theodore Roosevelt National Park". The origin of all of the plant species listed in that report were determined from Stevens (1963) and Flora of the Great Plains (Great Plains Association 1986).

Abstract:

Introductions of the zooplankton Bythotrephes longimanus and Cercopagis pengoi into the Great Lakes have drawn attention surrounding their suitability as prey for zooplanktivorous fishes. We used gut contents and stable carbon isotopes to quantify differential consumption and selection of the exotics by alewife (Alosa pseudoharengus) and rainbow smelt (Osmerus mordax) in Lakes Erie, Michigan, and Ontario. The exotics were more often consumed by alewife (up to 70% of gut content biomass) than by smelt (up to 25% of gut content biomass). Measured stable carbon isotope ratios of fish and ratios predicted from mixing models confirmed that the snapshot descriptions of diet through gut contents were representative of longer-term diets. While B. longimanus generally was selected for (14 of 17 sampling dates), C. pengoi was not a preferred prey item. Cercopagis pengoi was sometimes a large component of alewife diet because of its high densities in the environment. The exotic zooplankton are more important for alewife than for smelt, and consumption of the cladocerans varies throughout the growing season and among lakes, generally related to patterns of exotic abundance. Effects associated with consumption of the exotics should be high in alewife-dominated systems invaded by B. longimanus or large numbers of C. pengoi.

Abstract:

AbstractThe different types of calcareous exotic clasts (fragments of pre-existing rocks), embedded in the Paleocene siliciclastic deposits of the Istebna Formation from the Beskid Mały Mountains (Silesian Unit, Western Outer Carpathians), were studied and differentiated through microfacies-biostratigraphical analysis. Calcareous exotics of the Oxfordian- Kimmeridgian age prevail, representing a type of sedimentation comparable to that one documented for the northern Tethyan margin. The Tithonian exotic clasts (Štramberk-type limestones), which are much less common, were formed on a carbonate platform and related slope. The sedimentary paleotransport directions indicate the Silesian Ridge as a main source area for all exotics, which were emplaced in the depositional setting of the flysch deposits. The exotics constitute a relatively rare local component of some debrites. Proceedings of the sedimentological facies analysis indicate that these mass transport deposits were accumulated en-masse by debris flows in a deep-water depositional system in the form of a slope apron. Exotics prove that clasts of the crystalline basement and, less common, fragments of the sedimentary cover, originated from long-lasting tectonic activity and intense uplift of the source area. Mass transport processes and mass accumulation of significant amounts of the coarse-grained detrital material in the south facial zone of the Silesian Basin during the Early Paleogene was due to reactivation of the Silesian Ridge and its increased denudation. Relative regression and erosion of the emerged older flysch deposits were also forced by this uplift. These processes were connected with the renewed diastrophic activity in the Alpine Tethys.

Abstract:

A survey of exotic beetles that attack trees or shrubs in New Zealand found 51 species of mainly Australian (58) and European (25) origin In addition three biological control agents have been released against woody adventive plant pests The host range of most species is restricted to exotic crop and ornamental plants in New Zealand Nine polyphagous borers sometimes attack dead wood of indigenous species and at least one polyphagous root feeder may attack indigenous trees but the ecological impact of these species on indigenous forests appears negligible However some of the wood and bark borers as well as several defoliators are important pests of exotic crop and amenity plants Although this suggests that exotic phytophagous beetles pose a greater biosecurity threat to exotics than to indigenous species a greater surveillance effort in New Zealands indigenous forests appears necessary to detect potentially harmful invasions

Abstract:

Maize breeders frequently wish to use exotic germplasm in their breeding programs without losing specific characteristics of their adapted material. The objective of this study was to determine the optimal proportions of exotic germplasm to incorporate into adapted populations (F2 = 50% exotic, BC1 = 25% exotic, BC2 = 12.5% exotic and BC3 = 6.25% exotic) to form the initial foundation population and to determine the heterosis between adapted x exotics. We used six exotic populations of different origins and two adapted populations representing a Brazilian heterotic pattern. In 1993-94 and 1994-95, the parents, F1, F2, BC1, BC2, BC3 and four checks were evaluated in six environments in central Brazil using an 8 x 9 simple rectangular lattice design. Higher mean values for yield were obtained as the proportion of exotic germplasm decreased. Some backcrosses produced more than the adapted populations BR 105 (7.59 ton/ha) and BR 106 (8.43 ton/ha). The best results were obtained when incorporating 6.25 or 12.5% of exotic genes. This trend was true for root lodging, stalk lodging and ear diseases but not for plant and ear height. The midparent heterosis for yield varied from -16.1 to 40.3%. Midparent heterosis with positive and negative values were also found for the other traits. The results indicate the potential of exotic germplasm for developing good hybrids. After choosing the best exotic source, some recurrent selection might be appropriate in order to adapt and improve the exotic populations.

Abstract:

Since the invention of the quark model in 1964 hadrons are formed from a quark-antiquark pair called mesons or three quarks called baryons. However, QCD-motivated models for hadrons predict more complex structures on the hadrons components called generically exotics. These include tetraquark, pentaquark, the six-quark H-dibaryon, hybrid, and glueball mesons. Exotic hadrons have been systematically searched for in many experiments and studied in theories. In the past decade, lots of new hadrons that cannot fit into the normal mesons or baryons were discovered, the so-called [Formula: see text] states. Even so, no unambiguous candidates for any of those exotic configurations have been identified. This review presents an overview of the remarkable progress in the field of exotic hadrons over the past few years.

Full text

Abstract:

Exotic Pinus taeda L. plantations may be more productive than native ones. Several hypotheses may explain this difference; however, process models with a light-interception-driving variable cannot test these hypotheses without foliage display first being quantified in native and exotic trees. We quantified leaf area duration in North Carolina, USA (natural), and Gobernador Virasoro, Argentina (exotic), with no additional nutrients and optimum fertilizer treatments. More (60%–100%) foliage was displayed but for a shorter (∼86 fewer days) time per fascicle in the exotics than in the naturals. Study inference was limited, with only one native and one exotic site. However, while the sites were markedly different in soils, climate, resource availability, and genetics, and we observed significant differences in fascicle display and longevity, most fascicles at both sites survived two growing seasons: the one in which they were produced and the subsequent one. This robust finding indicates it would be reasonable to use two growing seasons for fascicle longevity in process modeling to test hypotheses explaining growth differences in native and exotic loblolly. Fertilization had no effect on any exotic tree parameter, but it increased natural tree fascicle number (24%) and length (30%).

Abstract:

Abstract Urban green spaces such as gardens often consist of native and exotic plant species, which provide pollen and nectar for flower-visiting insects. Although some exotic plants are readily visited by pollinators, it is unknown if and at which time of the season exotic garden plants may supplement or substitute for flower resources provided by native plants. To investigate if seasonal changes in flower availability from native vs. exotic plants affect flower visits, diversity and particularly plant–pollinator interaction networks, we studied flower-visiting insects over a whole growing season in 20 urban residential gardens in Germany. Over the course of the season, visits to native plants decreased, the proportion of flower visits to exotics increased, and flower-visitor species richness decreased. Yet, the decline in flower-visitor richness over the season was slowed in gardens with a relatively higher proportion of flowering exotic plants. This compensation was more positively linked to the proportion of exotic plant species than to the proportion of exotic flower cover. Plant–pollinator interaction networks were moderately specialized. Interactions were more complex in high summer, but interaction diversity, linkage density, and specialisation were not influenced by the proportion of exotic species. Thus, later in the season when few native plants flowered, exotic garden plants partly substituted for native flower resources without apparent influence on plant–pollinator network structure. Late-flowering garden plants support pollinator diversity in cities. If appropriately managed, and risk of naturalisation is minimized, late-flowering exotic plants may provide floral resources to support native pollinators when native plants are scarce.

Abstract:

BackgroundWith exotic pet species commonplace in the UK, owners are increasingly seeking veterinary advice regarding the health and welfare of their small mammals and reptiles. This study aimed to assess the confidence of veterinarians in the UK in treating and diagnosing rabbits, guinea pigs, small mammals and reptiles.MethodsA 41-question survey was promoted via social media, including on interest groups focused specifically at veterinary professionals. A total of 131 practising veterinarians in the UK completed the questionnaire.ResultsFrequency of presentation of exotic pets to a practice had a significant effect (P<0.01) on the confidence of veterinarians in treating them. Veterinarians who were presented with exotics more frequently had increased self-reported knowledge of their health and disease and were more confident in treating, diagnosing and anaesthetising them. Knowledge of and confidence in diagnosing and treating exotic pets were significantly less than for dogs and cats (P<0.001). There was a significant effect of length of time qualified on confidence in treating exotic pet species (P<0.01).ConclusionsIncreased provision and engagement with continuing professional development may increase veterinary confidence in diagnosing, treating and anaesthetising exotic pet species that are less commonly encountered in practice.

Abstract:

Assessment of village chicken egg quality parameters were conducted in two agro-ecology and eight rural kebeles, in Chelliya district. A total of 120 households were participated in the survey. Eggs were collected from 15 households for determination of egg quality parameters and two eggs were collected each from indigenous, cross breed and exotic, hence ten eggs were collected from each breed. Total of 240 eggs were used for this experiments. The objectives this study was to assess some quality parameters of eggs produced under scavenging production system. The exotics breed had higher egg production performance (198.80+10.45) than indigenous breed (155.2+10.45). The price of egg, pullet, and laying hen during the study period were 1.91±0.02, 38.43±0.87, and 44.24±0.83 Birr, respectively. The average Hough unit was 69.13, 74.50, and 82.63 (SE=2.21) local, crossbreed and exotics, respectively and 74.17 mm for highland and 76.67 mm for midland (SE=1.81). Average yolk color was 10.69, 10.35, 8.62 (SE=0.24) and average yolk index 354.93, 358.07, 377.13(SE=5.96) for local, crossbreed and exotics and also 9.58, 10.20 SE =0.19 and 357.05, 369.70(SE=4.87) in midland and highland. Except for Hough unit, the highland had higher mean values for these parameters than the eggs collected from midland. Similarly, exotic breed has higher mean values than that of indigenous and cross breed eggs, except Shell Thickness and Yolk Color. In summary there is a need for improvement in egg quality of the cross breeds and indigenous breeds.

Full text

Abstract:

Effective management of marine bioinvasions starts with prevention, communication among the scientific community and comprehensive updated data on the distribution ranges of exotic species. Despite being a hotspot for introduction due to numerous shipping routes converging at the Strait of Gibraltar, knowledge of marine exotics in the Iberian Peninsula is scarce, especially of abundant but small-sized and taxonomically challenging taxa such as the Order Isopoda. To fill this gap, we conducted several sampling surveys in 44 marinas and provide the first comprehensive study of marine exotic isopods from the Iberian Peninsula, the southern side of the Strait of Gibraltar (northern Africa) and the Balearic Islands. Exotic species includedIaniropsis serricaudis(first record for the Iberian Peninsula and Lusitanian marine province),Paracerceis sculpta(first record for the Alboran Sea ecoregion),Paradella dianae,Paranthura japonica(earliest record for the Iberian Peninsula) andSphaeroma walkeri. Photographs with morphological details for identification for non-taxonomic experts are provided, their worldwide distribution is updated and patterns of invasion are discussed. We report an expansion in the distribution range of all species, especially at the Strait of Gibraltar and nearby areas.Ianiropsis serricaudisandParanthura japonicaare polyvectic, with shellfish trade and recreational boating being most probable vectors for their introduction and secondary spread. The subsequent finding of the studied species in additional marinas over the years points at recreational boating as a vector and indicates a future spread. We call for attention to reduce lags in the detection and reporting of small-size exotics, which usually remain overlooked or underestimated until the invasion process is at an advanced stage.

Abstract:

ABSTRACTMuch of the unique native vegetation of Mauritius has been destroyed. Coastal ebony (Diospyros egrettarum I.B.K. Richardson) forest forms an extreme type of Mauritian lowland forest which no longer exists on mainland Mauritius and only survives on one offshore islet, Ile aux Aigrettes. Undisturbed D. egrettarum forest is resistant to invasion by exotic plants, which have now invaded most relict patches of native lowland vegetation in Mauritius. Human disturbance however, has allowed many exotics (particularly Flacourtia indica (Burm. fil.) Merrill) to invade and form new vegetation types. Much of the disturbance was caused by illegal woodcutting up to 1985, prompted by an acute fuelwood shortage in Mauritius. On the basis of 132 4 X 4 m quadrats, we recognize 10 types of natural, semi-natural and exotic vegeta-tion. The conservation of the remaining natural ebony woodland vegetation requires the total cessation of woodcutting and the eradication of Tabebuia pallida (Lindl.) Miers (potentially the most damaging exotic species).

Abstract:

QCD-motivated models for hadrons predict an assortment of "exotic" hadrons that have structures that are more complex than the quark-antiquark mesons and three-quark baryons of the original quark-parton model. These include pentaquark baryons, the six-quark H-dibaryon, and tetraquark and glueball mesons. Despite extensive experimental searches, no unambiguous candidates for any of these exotic configurations have yet to be identified. On the other hand, a number of meson states, one that seems to be a proton-antiproton bound state, and others that contain either charmed-anticharmed quark pairs or bottom-antibottom quark pairs, have been recently discovered that neither fit into the quark-antiquark meson picture nor match the expected properties of the QCD-inspired exotics. Here I briefly review results from a recent search for the H-dibaryon, and discuss some properties of the newly discovered states –the so-called XYZ mesons– and compare them with expectations for conventional quark-antiquark mesons and the predicted QCD-exotic states.

Abstract:

The Rocky Mountain exotic plant project is designed to determine (1) what exotics are capable of invading disturbed sites in major vegetational (environmental) zones of the Northern Rocky Mountains and (2) whether they are capable of invading near-climax closed vegetation in these zones. As an accessory activity we are determining (3) what natives are invading the same disturbed zones since we hope to find, among them, species likely to be successful on these sites and therefore species that might competitively exclude exotic invaders. A second accessory project of interest to managers, but with less immediate scientific value, was designed to (4) record the present distribution of major weeds along roadsides of Grand Teton National Park as they were recorded in Glacier during 1983-84.

Abstract:

The effects of introduced exotic species in natural environments are becoming important issues in conservation biology and natural resource management and recent scientific literature reveals increasing concern regarding the spread of invasive exotic plant species (Allen, 1996; Vitousek et al. 1996; Walker and Smith, 1997). Ecological consequences of these species include increased competition for space, water, and nutrients with native plants (which could result in a decrease in biodiversity), decreased forage quality for native ungulates, and changes in the microenvironments where the establishments took place (Woods, 1997). Sheley et al (1998) list several ecologically and economically detrimental impacts of exotic species. The National Park Service recognizes the need to protect ecosystems from exotic species (National Park Service, 1997) through management based on the ability to predict species distributions and spread, and monitoring in areas that are most susceptible to invasion. Recommended strategies for preventing the spread of exotic species include developing an early warning system to identify and eradicate new infestations of exotic plants in National Parks, and continued inventory and monitoring of exotic plants (National Park Service, 1997). These strategies will be based on assessment of the distribution and spread of exotic plants (National Park Service, 1997) using remote sensing and Geographic Information Systems (GIS) technologies for mapping and monitoring exotic plants, and models to predict the invasiveness and spread of exotic plants. In Grand Teton National Park (GTNP), exotic species are a great concern for park managers (National Park Service, 1997). Of the 1000 species of flowering plants within GTNP, there are also four (possibly five) rare plants that may be threatened as a result of competition with exotics (Wyoming Rare Plant Technical Committee, 1994): Draba borealis (Boreal draba), Epipactis gigantea (Giant helleborine), Lesquerella carinata var. carinata (Keeled bladderpod), Lesquerella paysonni (Payson's bladderpod), and possibly Draba densifolia var. apiculata (Rockcress draba). The continued survival of these sensitive plants in GTNP increases the need for management of exotic plants. GTNP has implemented a classification system for exotic plant species that consists of three priority levels (GTNP, 1997a). Priority 1 species are designated as "noxious" since they are capable of invading natural ecosystems and disrupting or displacing native vegetation. Currently, there are thirteen exotic plant species with a Priority 1 status within GTNP (Table 1 ).

Abstract:

ABSTRACTTwo stands of mature evergreen wet forest in Mauritius (Mascarene Islands) were sampled for floristic composition to assess the extent of invasion by weedy exotic phanerogams (Brise Fer, 550 m alt.; Bon Courage, 200–260 m alt.). All individuals ≥ 2.5 cm dbh were recor ded in 50×2 m transects totalling 0.1 ha at each site, and 2×2 m seedling plots totalling 40 m were also sampled at each site. Both forests showed a high degree of invasion. Although exotics constituted only 5% of woody species ≥ 2.5 cm dbh at Brise Fer and 14.5% at Bon Courage, they comprised 34.8% and 20.8% of the individuals, respectively. Seedling plots at both sites were dominated by exotics, which comprised 20.6% of the species and 97.4% of the individuals at Brise Fer, and 22.2% of the species and 73.9% of the individuals at Bon Courage. Comparisons are made with Macabé forest, sampled nearly 50 years ago. These data suggest that unless steps are taken to check the spread of exotics, floristic composition at these sites will shift towards total invasion and degradation as has occurred elsewhere on Mauritius.

Abstract:

Aims. Globular clusters produce many exotic stars due to a much higher frequency of dynamical interactions in their dense stellar environments. Some of these objects were observed together with several hundred thousand other stars in our MUSE survey of 26 Galactic globular clusters. Assuming that at least a few exotic stars have exotic spectra (i.e. spectra that contain emission lines), we can use this large spectroscopic data set of over a million stellar spectra as a blind survey to detect stellar exotica in globular clusters. Methods. To detect emission lines in each spectrum, we modelled the expected shape of an emission line as a Gaussian curve. This template was used for matched filtering on the differences between each observed 1D spectrum and its fitted spectral model. The spectra with the most significant detections of Hα emission are checked visually and cross-matched with published catalogues. Results. We find 156 stars with Hα emission, including several known cataclysmic variables (CV) and two new CVs, pulsating variable stars, eclipsing binary stars, the optical counterpart of a known black hole, several probable sub-subgiants and red stragglers, and 21 background emission-line galaxies. We find possible optical counterparts to 39 X-ray sources, as we detected Hα emission in several spectra of stars that are close to known positions of Chandra X-ray sources. This spectral catalogue can be used to supplement existing or future X-ray or radio observations with spectra of potential optical counterparts to classify the sources.

Full text

Abstract:

Differences in species composition of urban bushland sites that had been subjected to increasing degradation and progressive invasion of Pittosporum undulatum Vent. were assessed using nonparametric multivariate and other statistical techniques. Increasing suburb age was found to significantly affect community pattern as a whole, specifically through increased proportions of exotic species, decreased native species richness and sustained shifts in the relative importance of individual species. Older suburbs were typified by species that were mesic, fire-sensitive, shade-tolerant and adapted to relatively moist, nutrient-rich edaphic conditions. These species included P. undulatum and many invasive exotics. Many native species decreased substantially in rank importance with increasing suburb age, to the point of elimination in older suburbs. These included one vulnerable taxon (Tetratheca glandulosa Sm.). Overall community pattern was correlated with abundance of P. undulatum, fire and human disturbance. Relative cover of P. undulatum was found to be significantly correlated with increased proportions of exotic species and reduced native species richness and diversity. While most exotic species were concentrated within 30 m of the suburban edge, it is suggested that most management effort should be directed at those exotic species that commonly establish throughout bushland remnants. The study also provided an opportunity to test the application of the multivariate software package PRIMER in assessing environmental impact on vegetation communities.

Abstract:

Of the many exotic plants that have become naturalized in North America, only a small proportion are pests capable of invading and dominating intact natural communities. In the present study, we tested the hypothesis that the most invasive plants are phytochemically unique in their new habitats. A comparison of exotic plant species that are highly invasive in North America with exotics that are widespread, but non-invasive revealed that the invasive plants were more likely to have potent secondary compounds that have not been reported from North American native plants. On average, the compounds found in the invasive plants were reported from fewer species, fewer genera and fewer families than those from non-invasive plants. Many of the unique phytochemicals from invasive plants have been reported to have multiple activities, including antiherbivore, antifungal, antimicrobial and allelopathic (phytotoxic) effects, which may provide the plants with several advantages in their new environments.

Eleven species of the family Chitinoidellidae Trejo, 1975, belonging to the genera Chitinoidella, Daciella, Dobeniella, Longicollaria and Popiella are described here. The majority of studied samples have been assigned to the Boneti Subzone of the Chitinoidella Zone. Exotics with chitinoidellids represent environments which can be interpreted as platform margin reefs, slope of platform and inner platform

Abstract:

AbstractThe number of invasive exotic plant species establishing in the United States is continuing to rise. When prevention of exotic species from entering into a country fails at the national level and the species establishes, reproduces, spreads, and becomes invasive, the most successful action at a local level is early detection followed by eradication. We have developed a simple geographic information system (GIS) analysis for developing watch lists for early detection of invasive exotic plants that relies upon currently available species distribution data coupled with environmental data to aid in describing coarse-scale potential distributions. This GIS analysis tool develops environmental envelopes for species based upon the known distribution of a species thought to be invasive and represents the first approximation of its potential habitat while the necessary data are collected to perform more in-depth analyses. To validate this method we looked at a time series of species distributions for 66 species in Pacific Northwest and northern Rocky Mountain counties. The time series analysis presented here did select counties that the invasive exotic weeds invaded in subsequent years, showing that this technique could be useful in developing watch lists for the spread of particular exotic species. We applied this same habitat-matching model based upon bioclimatic envelopes to 100 invasive exotics with various levels of known distributions within continental U.S. counties. For species with climatically limited distributions, county watch lists describe county-specific vulnerability to invasion. Species with matching habitats in a county would be added to that county's list. These watch lists can influence management decisions for early warning, control prioritization, and targeted research to determine specific locations within vulnerable counties. This tool provides useful information for rapid assessment of the potential distribution based upon climate envelopes of current distributions for new invasive exotic species.

Full text

Abstract:

AbstractLong-distance exchange of exotic preciosities, while it can occur in any sociopolitical context, may be associated with both chiefly formation and state hegemony. In the south central Andes, shared stylistic elements in early complex societies of Paracas-Nasca on the Peruvian south coast and Pukara in the altiplano suggest their contact via intermediate areas. Unfortunately, interpretations of the interaction of these great traditions tend to neglect indigenous sociopolitical development in regions between the two culture areas. Recent systematic survey in one such intermediate region, Peru's Moquegua Valley, has shed light on an indigenous pre-Tiwanaku culture with distinctive regional settlement patterns, complex mortuary practices, and a local ceramic tradition known as Huaracane (385 cal B. C-cal A. D. 340). Surface collections and test excavations confirm a minimal presence of exotic Pukara and Paracas-Nasca ceramics and textiles in association with elite local residential contexts and a late Huaracane mortuary tradition known as “boot tombs” that appears after 170 cal B. C. As there is no general emulation of foreign styles, domestic activities, or practices, an agency-oriented local perspective is favored over globalist colonial or clientage models to explain the role of exotica in a climate of competitive sociopolitical development.

Abstract:

The future of livestock breeding depends on the availability of a large gene pool from which useful traits can be selected. Genetic conservation is therefore vital, and should be aimed at all existing breeds, regardless of their usefulness under present conditions. Developed countries can afford to maintain stocks of rare breeds, but firm measures are still needed in the developing world, especially where indigenous breeds are threatened by the import of exotic strains. More attention should be given to the use of indigenous breeds in livestock development programmes, and genetic impact analysis should be routine where exotics are used.

Abstract:

We list plants whch are commonly established in road cuts in fifteen major Northern Rocky Mountain environmental types. We expect them to establish well on new disturbances in the same environmental types. Thus, our list of natives can be used to choose plants for reintroduction of natives to construction sites and other disturbed areas; additional data on life form, aggressiveness (cover), and altitudinal distribution will be useful for choosing among seeding candidates and selecting seed sources for the reseeding. And, our list of establishing exotics will identify the weeds most likely to colonize a site, their aggressiveness on disturbed sites, and their capacity to enter adjacent undisturbed vegetation; this list will caution against introduction of certain exoti (e.g. Poa pratensis, Phleum pratense, and most Trifoliums-- as well as noxious weeds) and will be the basis for plans to control locally noxious exotics early and aggressively.
