Abstract:

Megabranchiellagen. nov. (Ephemeroptera: Baetidae) is established as a new baetid mayfly genus from northern Thailand. Two new species, Megabranchiella scutulatasp. nov. and Megabranchiella longusasp. nov., are described. This genus is distinguished from other Baetidae by abdominal segment I, bearing a pair of enlarged, ventrally oriented single gills, covering abdominal sternites II–V; other gills have normal size and are dorsolaterally oriented. The two new species Megabranchiella longusasp. nov. and Megabranchiella scutulatasp. nov. can be differentiated by the setation of femur dorsal margin and the shape of abdominal gill I. This mayfly genus was found in flowing water with cobble microhabitats in headwater streams of northern Thailand.

Abstract:

In a benthic community on a continuous flat granite substrate in a third-order coastal forest stream, the dominant chironomid (Cricotopus) increased in number when shrimps (Macrobrachium olfersi and Potimirim glabra) and baetid ephemeropterans were excluded by electricity. The response appeared to be mediated by an increase in periphyton and sediments, rather than a reduction of direct predation or interference. Chironomids, periphyton and sediments decreased significantly compared to the control when shrimps only were excluded. Baetid ephemeropteran appeared to be the most important determinants of periphyton and sediment mass; the density of chironomids appeared to follow the quantity of periphyton and sediments.

Abstract:

Indirect foodweb interactions often determine the dynamics of aquatic ecosystems. Predators may reduce the activity of herbivores, which, in turn, may cause basal resources to increase. We studied the patterns of distribution of periphyton (organic and inorganic mass and chlorophyll) on rocks in pools in two Atlantic rainforest coastal streams that varied with respect to the presence or absence of fish. A steep waterfall apparently prevented most fish species from colonising the upper parts of one stream; the other stream was apparently naturally without most species of fish. When fish were present, atyid shrimps and baetid mayflies were less abundant compared with parts of the streams without fish. Concomitant with this, the quantity of periphyton organic and inorganic masses was much greater in the presence of fish. Previous experiments showed that atyid shrimps (Potimirim glabra) and baetid mayflies could reduce the quantity of periphyton by grazing and bioturbation. We deduce that fish inhibit the grazing and bioturbing activities of Potimirim and baetid mayflies, which resulted in larger quantities of inorganic and organic mass of periphyton in parts of streams with fish. Cascading interactions may be common in Atlantic coastal forest streams.

Abstract:

Field experiments were carried out to determine whether there are diel variations in the effect of spates on baetid mayflies. Short-term spates were created in experimental streamside channels by pumping filtered creek water into selected channels at various times of day, resulting in three- or four-fold increases in discharge. Drift samples were collected before, during, and after spates; benthic samples were collected before and after. Drift rates of Baetis from channels in spate were higher than controls at all times of day. Natural increases in drift were observed in all channels after sunset, and drift rates from channels in spate were highest at this time. The susceptibility of nymphs to drift from channels was calculated as the ratio of drift densities in spate and control channels. Baetis appeared to be more vulnerable to spates after sunset than at dawn or midday. In unmanipulataed flow, large nymphs occurred most frequently in the drift after sunset. Spates had no apparent effect on the size distribution of nymphs in the drift compared with unmanipulated flows at the same time. These spates were not large enough and (or) long enough to greatly decrease mayfly densities in the benthos. It is notable, however, that benthic densities of Baetis were reduced significantly only by one spate at dusk.

Abstract:

Salinity levels are rising in many freshwater environments, yet there are few direct measurements of salinity tolerance of organisms likely to be salt sensitive. The relative salinity tolerance to artificial seawater of macroinvertebrates from the Barwon River in Victoria, Australia, was assessed by measuring the 72-h lethal concentrations required to kill 50% of individuals (LC50). LC50 values ranged from an electrical conductivity of 5.5 to 76 mS cm–1 (mean 31 mS cm–1, n = 57) and followed a log-normal distribution. The most salt-sensitive groups tested were Baetidae (LC50 value range: 5.5–6.2 mS cm–1), Chironomidae (10 mS cm–1) and several soft-bodied non-arthropods (Oligochaeta, Gastropoda, Nematomorpha, Tricladida and Hirudinea; 9–14 mS cm–1). Other groups, from least to most tolerant, were non-baetid Ephmeroptera (>12.6–15 mS cm–1), Plecoptera (>12.6–>20 mS cm–1), Trichoptera (9–>26 mS cm–1), Corixidae (18–26 mS cm–1), non-corixid Hemiptera (33–44 mS cm–1), Coleoptera (19–54 mS cm–1), Hydracarina (39 mS cm–1) and Odonata (30–55 mS cm–1), and macrocrustaceans (Decapoda, Isopoda and Amphipoda; 38–76 mS cm–1).

Abstract:

Acentrella nadineae McCafferty, Waltz, & Webb, 2009 is broadly distributed in cool, clean, swift rocky streams across parts of the southeast, northeast, and midwestern United States, but currently its adult stages are unknown. The difficulty associated with successfully rearing nymphs of Acentrella species is mostly responsible for our lack of knowledge of adult life stages. New field observations of A. nadineae nymphs from the Hubbard River, Massachusetts, USA were used to modify an already successful rearing system for baetid nymphs to obtain a reared series of male and female imagos for study. Both life stages were photographed alive and are described herein for the first time. In addition, details of the modified rearing system and notes on the unusual madicolous behavior of near final instar nymphs are presented.

Callibaetis radiatus, Camelobaetidius billi, and Cloeodes irvingi are for the first time reported from Brazil. The distribution of several species previously recorded from this region is significantly extended, and at least regarding Baetidae documentation, the Southeast region becomes the better known in Brazil. Fifteen genera and 25 species of the 18 genera and 42 species reported from Brazil, were found in this region. A checklist with the species found in the Southeast region and a key to the nymphs of the genera are also provided.

They posses a Pan American distribution, from Argentina to Canada. They are considered the sister group of the genus Corinnella Thomas & Dominique, 2006. The genus consists of 44 species, 25 of them are described based only on nymphs, five based on adults, 13 based on nymphs and male imago, and one based on nymph and femele imago. Many species have large area of distribution, with location and longitudinal variation in characters historically considered important for the taxonomy of Baetidae.

Abstract:

At the present time there is enormous opportunity to investigate the epigraphic assemblages of the Roman province of Baetica. The steady progression in the research and publication of the revised editions of the Corpus Inscriptionum Latinarum is providing a significant new study resource for the material which takes appropriate account of the archaeological contexts of the material wherever possible. This research takes full advantage of current advances in the epigraphic discipline, and brings the benefit of a fully contextualised archaeological methodology to a study of approximately 1000 Latin inscriptions from a selection of twelve towns predominantly located across the landscape of the lower and western Guadalquivir Valley in the Comunidad Autónoma de Andalucía of southern Spain. Discussion of the place of inscriptions within Roman towns is not new, but unique to this research is the way in which the methodology contextualises the material within its appropriate spatial, historical and social context. It builds upon a background of social theory to model the relationship between human society and its material culture in an attempt to identify a series of relationships not considered before with this material. Inscriptions are meticulously analysed for patterns of common behaviour in the way that they were designed and erected. More specifically, it identifies instances where these similarities extend beyond individual settlements, and conversely where individual settlements display distinctly unique characteristics that distinguish them from the other towns studied here. An understanding of the social context of inscriptions enables us to interpret the motivations stimulating the use of inscribed monuments throughout the study region. These are key to answering the question asked by this thesis, namely how the inscriptions from the urban communities of Early Roman Baetica reflect the interconnected nature of Baetican society and provide evidence for social connectivity throughout the study region.

Abstract:

La station d'etude se situe sur le niandan, affluent guineen du niger. Ce cours d'eau a ete traite par insecticide toutes les semaines d'avril a aout en 1987 et 1988. Trois produits ont ete utilises: le b. T. (aux basses eaux, en avril et mai), le temephos et la permethrine (a la remontee des eaux et en hautes eaux, de juin a aout). Avant le premier traitement insecticide du niandan, la microdistribution des baetidae en saison seche (fevrier a avril) est bien expliquee par les criteres de stratification choisis pour l'echantillonnage: vitesse du courant, presence ou absence de depot de vase, morphologie des podostemaceae (presence ou absence de tiges dressees) et support (sable, face superieure des substrats rocheux et face inferieure des pierres). De fevrier a avril, les densites augmentent chez pseudopanota bertrandi et p. Muganinani alors qu'elles diminuent chez les especes codees a1 et a2. Nous n'avons pas observe de differences de microdistribution et d'evolution temporelle (de fevrier a avril) selon l'age des larves. La duree de la phase larvaire, estimee par le suivi de la croissance d'individus mis en elevage, est inferieure a un mois chez la plupart des especes. A proximite du point d'epandage (duree du passage de l'insecticide egale a 10 minutes), les experiences en gouttiere montrent que toutes les especes testees sont fortement resistantes au b. T. (decrochement inferieur a 5%) et faiblement resistantes a la permethrine (decrochement superieur a 95%). La resistance au temephos varie selon les especes. Pour ces trois insecticides, la sensibilite des larves ne varie pas nettement selon leur age. La comparaison des effectifs de la faune en saison seche avant (1987) et apres traitement insecticide (1988 et 1989) montre que 5 a 7 mois apres l'arret du traitement insecticide, toutes les especes ont retrouve (voire parfois meme depasse) leurs effectifs

Despite the fact that the taxonomy of the family has improved in the last decades, the knowledge of the genus is still incipient. The aim of this study was to survey the species of Callibaetis in three municipalities of Amazonas state, as well as compiling taxonomic information on species of this genus deposited in various zoological collections in Brazil, and to develop an identification key for nymphs and adults of the species from Brazil. Samples were collected in artificial lakes, ponds, streams and floodplains in the cities of Manaus, Presidente Figueiredo and Iranduba. Nymphs collected were reared in the field, allowing their association with adults. Material from the following collections were examined: Universidade Federal de Pernambuco, Universidade Federal do Espírito Santo, Universidade Federal do Rio de Janeiro, Universidade Estadual de Campinas, Universidade do Estado do Mato Grosso, Universidade Comunitária da Região de Chapecó. The Brazilian species not collected were reviewed based on literature and photographs sent from museums. Seven new species were found and described based on nymphs and adults; males of C. jocosus were redescribed; and C. gonzalezi and C. sellacki were recorded for the first time from Brazil. The number of species of this genus known from Brazil increase from nine to eighteen after the present work, and the diagnosis of the previously known species, as of the genus were improved.<br>As espécies do gênero Callibaetis Eaton, diferente dos demais membros da família foram descritas com base nos estágios alados, muitas vezes de forma inadequada. Apesar do conhecimento taxonômico da família ter sido incrementado nas ultimas décadas, o conhecido sobre o gênero Callibaetis continua incipiente. O objetivo deste trabalho foi coletar em três municípios do estado do Amazonas, bem como compilar informações taxonômicas através da análise de material depositado em diferentes coleções brasileiras, desenvolvendo ao final uma chave de identificação para as ninfas e adultos de ambos os sexos registrados para o Brasil. As coletas ocorreram em lagos artificiais, poças, várzea e igapó nos municípios de Manaus, Presidente Figueiredo e Iranduba. Ninfas foram criadas em campo permitindo a associação de estágios. Material proveniente das seguintes coleções foi examinado: Universidade Federal de Pernambuco, Universidade Federal do Espírito Santo, Universidade Federal do Rio de Janeiro, Universidade Estadual de Campinas, Universidade do Estado do Mato Grosso, Universidade Comunitária da Região de Chapecó. As espécies brasileiras não coletadas tiveram sua análise com base na literatura e em fotografias dos museus. Sete novas espécies foram descritas baseadas nas ninfas e adultos de ambos os sexos; o macho de C. jocosus foi redescrito; C. gonzalezi e C. sellacki são pela primeira vez registrados para o Brasil. O número de espécies do gênero conhecidas para o Brasil foi dobrado, passando de nove para dezoito, as diagnoses das espécies do gênero foram melhoradas.

Abstract:

The province of Baetica, in present-day Spain, was one of the most important areas in the Roman Empire in terms of politics, economics, and culture. And in the late medieval period, it was the centre of a rich and powerful state, the Umayyad Caliphate. But the historical sources on the intervening years are limited, and we lack an accurate understanding of the evolution of the region. In recent years, however, archaeological research has begun to fill the gaps, and this book-built on more than a decade of fieldwork-provides an unprecedented overview of urban and rural development in the period.

Abstract:

<em>Abstract.</em>—The relationship between added soluble nutrient concentration and the abundance and taxonomic composition of stream insects was determined in an experiment using streamside troughs. Target phosphorus (P) concentrations were 0, 0.5, 2.5, 5, 10, and 50 µg/L at a N:P ratio of 1:1 (wt.:wt.). All treatments were replicated three times except 50 µg/ L, which was unreplicated. Peak algal biomass (PB) increased with nutrient concentration linearly to 7.4 mg/m<sup>2</sup> at 2.5 mg P/L and reached an asymptote at 9.2 mg/m2 (2.7× the controls) at 10 µg P/L. Adult baetid mayflies increased 2- and 4-fold when caught in drift nets and emergent insect traps, respectively, at a phosphorus concentration of 10 µg/L compared with controls. Numbers of benthic baetids, nemourid, and perlodid stoneflies and hydroptilid and polycentripodid trichopterans increased 1.6, 2.3, 2.9, 2.8, and 1.2-fold, respectively, at 10 µg P/L compared with controls. Adult and nymphal baetids and benthic nemourids, perlodids, and hydroptilids initially increased rapidly at nutrient concentrations of 0–2.5 µg P/L and reached asymptotes at concentrations of 2.5–10 µg P/L. Exclusion of insects from a single unfertilized trough suggested that grazing limited peak biomass of periphyton to low levels. Increased abundances of aquatic insects resulted from greater periphyton availability at relatively low dissolved-nutrient additions ranging from 0.5 to 10 µg P/L.

The article contains materials with reference to the basic parameters, fundamental in the cultivation technology of the Siberian sturgeon Acipenser baerii in a recirculating system, such as temperature, dissolved oxygen, pH and water quality. The calculation and estimation of the production of TAN (total ammoniacal nitrogen), the final result of the transformation of proteins, allows an effective monitoring of the volume of water, the amount of food administered and the efficiency of the biological processes of nitrification in a recirculating system intended for the growth of the Acipenser baerii species. The importance of these systems lies in their ability to make resource use more efficient, reducing water and land consumption, minimizing pollution and disease transmission risks, and facilitating sustainable and economic fish production

Abstract:

Dousman Creek, located in northeastern Iowa, is a Class ?B? coldwater stream that supports a trout population and is listed among the Outstanding Iowa Waters (Iowa Department of Natural Resources 2010, 2016). The Heartland Inventory and Monitoring Network (Heartland Network) of the National Park Service (NPS) has been monitoring aquatic communities (fish and invertebrates) in Dousman Creek within Effigy Mounds National Monument (NM) since 2008. Corresponding physical habitat and water quality were also collected during biotic sampling. The objectives of this long-term monitoring program are to assess the status and trends in the biotic stream community and relate these trends to environmental variables. The purpose of this report is to summarize the baseline aquatic community data collected during three sampling events conducted from 2008 to 2017. The fish community was dominated by the intolerant cool/cold-water species Brown trout (Salmo trutta) and Mottled sculpin (Cottus bairdii) in 2008, while more tolerant white sucker (Catostomus comersonii) and Johnny darter (Etheostoma nigrum) were most abundant in 2014. During 2017, fish community composition was more evenly distributed among species present. Benthic invertebrate samples were dominated by the moderately intolerant mayfly genus Pseudocloeon and blackfly genus Simulium in 2008 and 2014, while the invertebrate samples in 2017 were dominated primarily by a tolerant, mayfly taxa (Baetis) and Oligochaetes. The abundance of aquatic invertebrates in 2017 was more than ten times lower than invertebrate abundance in 2008 and 2014. Water quality data collected by the Heartland Network did not indicate any of the five parameters (temperature, dissolved oxygen, pH, specific conductance, or turbidity) exceeded the Iowa Department of Natural Resources water quality standards, however the number of hourly measurements were low (4?20 measurements) depending on year sampled. Three years of data are currently insufficient to fully characterize the stream integrity of Dousman Creek based on fish and invertebrate communities. Continued long-term monitoring of Dousman Creek will allow for better assessment of the biotic integrity and overall quality of the stream.

Full text

Abstract:

Land use changes that degrade water quality and stream habitat can negatively impact aquatic communities. Monitoring trends in aquatic community composition and habitat conditions is a robust way to assess stream integrity and health. Herbert Hoover National Historic Site (NHS) is in eastern Iowa where dominant land use consists of row-crop and grassland agriculture. A portion of an unnamed tributary of the West Branch of Wapsinonoc Creek, known as Hoover Creek, flows through the park. In 2008, the Heartland Inventory and Monitoring Network (Heartland Network) of the National Park Service (NPS) began monitoring aquatic communities (fish and invertebrates), physical habitat, and water quality at Hoover Creek within the park. This report summarizes four years of data to assess the baseline conditions of Hoover Creek within Herbert Hoover NHS. Aquatic invertebrate taxa richness ranged from 21 to 32 among all years monitored. Three of these taxa are sensitive to poor water quality and habitat conditions. The invertebrate community was dominated by true flies in the Chironomidae family, Oligochaete worms, and mayflies in the Baetidae family. These taxa are all tolerant of poor water quality and habitat conditions. However, in 2011, the sensitive caddisfly Ceratopsyche was also abundant. Mean Hilsenhoff Biotic Index values indicated the invertebrate community fluctuated over time, ranging from fairly poor in 2017 to good condition in 2011. Ten fish species were collected at Hoover Creek across the four years sampled with seven of those species found in all years. All fish species collected were either moderately tolerant or tolerant to poor habitat and water quality conditions; the community was dominated by johnny darter (Etheostoma nigrum), creek chub (Semotilus atromaculatus), and blacknose dace (Rhinichthys atratulus). Based on the Index of Biotic Integrity developed for Iowa streams, the fish community ranged from fair condition in 2008, 2014, and 2017 to good condition in 2011. Hoover Creek was found to have predominately fine to medium gravel substrate with high embeddedness, and banks were steep and tall and consisted of fine silt substrate. With the exception of turbidity after a rain event in 2008, water quality parameters were within state standards. The four years of stream biota data coupled with habitat data should form a good baseline for assessing changes or trends in the aquatic community and overall stream health of Hoover Creek.
