Steppe ecosystems worldwide are affected by agricultural development and generally unprotected. Spanish shrub-steppes contain endangered avifauna, and this paper analyses their state of habitat conservation, the changes that have occurred in the last decade, primary productivity and its relationship with land exploitation and the richness of threatened birds, and avifauna responses to habitat loss. Fifty steppe remnants distributed throughout Spain and inhabited by Dupont's lark Chersophilus duponti, an endangered passerine representative of shrub steppe-like habitat, were studied. The study f

In the recreational zone of "Homilshanski Lisy" National Park 137 species of birds were identified during the period 1980–2015, of which 127 species nest, 8 winter, and 2 observed during the spring migration. The nesting species are distributed in 4 ecological groups dominated by dendrophylls (67 species), with fewer limnophylls-fresh water species (29), campophylls-open country species (16) and sclerophylls (11). Among the nesting birds 11 landscape-genetic faunal assemblages were distinguished, dominated by typical nemoral-woodland (19%), tropical (14%) and forest-steppe (13%) species. The a

Forest biogeocenosis is a necessary environment for the normal existence of many species of wild animals, including birds. Recently, however, a gradual decrease in their numbers is observed in most forest areas of the Forest-Steppe zone. This indicator is one of the most important criteria for estimation of the general condition of this or that ecosystem. In this regard, specialists-zoologists, ornithologists, etc. pay great attention to the study of this issue (Koval' N.F. 1982).

Abstract:
Approximately 50-60% of native sagebrush steppe has been lost to non-native grasses, which has contributed to population decreases for sagebrush-associated songbirds. Removal of non-native grasses and restoration treatments may return structure and function of sagebrush steppe and ultimately benefit songbirds, but their responses must be evaluated. To determine breeding songbird community responses to sagebrush restoration treatments, in 2013 we conducted bird surveys at restored plots at the Kelly Hayfields restoration area in Grand Teton National Park, Wyoming.

Abstract:
Birds are part of the special magic of grasslands. Birds such as McCown’s Longspurs (scientific names are given in the Appendix) or Horned Larks, which seem to disappear against the background of grass, soil, and stones when they are on the ground, launch breathtaking courtship flights punctuated by tinkling songs and mothlike flutterings. Male Lark Buntings, incongruously black and white (Fig. 9.1A) against the subdued tones of the grassland, may break into their morning territorial displays or gather together spontaneously in melodious group choruses. Mountain Plovers may burst from underfoot into utterly convincing broken-wing distraction displays. Ferruginous and other hawks (Fig. 9.1B) may suddenly plummet from the blue skies above. Sightings of relatively rare species such as Chestnut-collared Longspurs (Fig. 9.1C) may bring joy to dedicated bird-watchers. Birds give the shortgrass steppe an aura that Bouteloua alone cannot. Yet birds have not figured importantly in most discussions of grassland ecology. They are generally drab and brownish, so they have not attracted much attention from the general public, and their contributions to ecosystem production and energy flow are small, so they have not been of much interest to ecologists studying ecosystem processes. However, grassland birds are showing the most widespread and consistent population declines of any group of North American birds (Herkert, 1995; Knopf, 1994; Peterjohn and Sauer, 1999). As a consequence, they have become a focus of conservation concern (Brennen and Kulvesky, 2005; Vickery and Herkert, 2001). The history of ornithological research in the shortgrass steppe is closely intertwined with the broadly interdisciplinary work conducted during the IBP in the late 1960s and early 1970s, and more recently (since 1982) as part of the NSF LTER program. In this chapter we describe the birds of the shortgrass steppe and summarize pertinent research that has been conducted on them during the past 40+ years. Our aim is to synthesize this information to provide a perspective on how environmental factors may relate to population fluctuations, on spatiotemporal shifts in community composition, and on patterns of habitat occupancy among the birds of the shortgrass steppe. We conclude by noting some continuing research priorities that have become more critical as conservation concerns about these birds have heightened.

This chapter explores the range of work and practices involved in producing A History of the Birds of Europe, one of the most ambitious bird books of the late nineteenth century. Richard Bowdler Sharpe worked with Dresser on the first twelve parts and then withdrew from the project as he was overworked; Dresser completed the book alone. The book was issued in eighty-four parts and took eleven years to complete (1871–82). Dresser’s methods of producing the articles are outlined. Plates were illustrated by J. G. Keulemans (smaller numbers of plates were illustrated by other artists). The book was based on the latest discoveries, many of them made by Henry’s collaborators and those who provided him with bird skins. The book was a major step in synthesising the widely disparate information on the birds of Europe into a globalised, reliable set of knowledge.

Abstract:
On April 28, 1987, a biologist hiking through the remote Alakai swamp on the island of Kauai paused to listen to the sweet, flutelike song of a distant bird. He recognized the song as belonging to a Kauai ’o’o (Moho braccatus), a sleek chocolate-brown bird native to these woods. He was surely aware of the significance of this particular song, for during the past four years this particular ’o’o, the very last of its kind, had been the object of much attention among scientists and conservationists. But he could not have known that he was about to become the last person ever to hear it. The next time biologists visited the Alakai swamp, the ’o’o was gone, and yet another American species had moved from the realm of the living to the realm of the dead. The causes of the Kauai ’o’o’s extinction are reasonably clear, although the precise role each factor played in the species’ demise is debatable. Much of the bird’s forested habitat was destroyed for agriculture, leaving only a relatively few safe havens on steep slopes or in wet, inaccessible places. Most of these places, in turn, were eventually overrun with alien species, including feral pigs that destroyed the native vegetation, as well as plants and songbirds transported to Hawaii from around the world. The introduction of mosquitoes to Hawaii, which occurred in 1826 when the crew of a sailing ship dumped the mosquito larvae—infested dregs from their water barrels, created additional problems for Hawaii’s beleaguered birds. The mosquitoes became a vector for the spread of avian malaria and avian pox, diseases that were probably carried by the introduced birds. The native avifauna, presumably including the ’o’o, lacked resistance to these diseases, and many species quickly succumbed. Soon, only the forests at higher elevations, where cold temperatures kept the mosquitoes at bay, offered a disease free environment for the native birds. Eventually, however, the mosque toes reached even these forests, including the Alakai swamp, abetted by feral pig wallows, which created pools of stagnant water ideal for breeding mosquitoes. Thus a combination of factors, including habitat destruction, alien species, and diseases, contributed to the demise of the Kauai ’o’o.

Abstract:
Parasites both affect and are affected by the behavior of birds. Moreover, specific avian behaviors can either suppress or augment parasite spread, depending on context and parasite transmission mode. The chapter focuses on major categories of behavior important for the key steps of the parasite transmission process: first, the likelihood of exposure to parasites; second, host susceptibility to infection and degree of infectiousness reached once exposed; and third, the likelihood of spreading infection to other hosts or vectors. The chapter begins by discussing behaviors that birds use to minimize exposure to parasites (e.g., preening and other ‘antiparasite’ behaviors) and the immediate effects of infection on behavior (e.g., lethargy and other ‘sickness’ behaviors). The focus then truns to foraging and movement, which are specific behaviors that both can increase exposure to parasites and are altered by infection. Finally, the chapter considers how a suite of behaviors including social interactions, individual personality, and mating behaviors can affect and are affected by parasites in ways relevant to all three steps of the parasite transmission process. Throughout, the chapter highlights and integrates areas in which recent advances have been made or for which more data are sorely needed in avian systems, emphasizing directions for future research at the intersection of avian behavior and infectious disease ecology.

Abstract:
Although livestock are the most obvious consumers on the shortgrass steppe, they are certainly not the only consumers. However, livestock may influence the other consumers in a number of different ways. They may directly compete for food resources with other aboveground herbivores. There is behavioral interference between livestock and some species of wildlife (Roberts and Becker, 1982), but not others (Austin and Urness, 1986). The removal of biomass by livestock alters canopy structure (physiognomy) and influences microclimate. Bird, small-mammal, and insect species can be variously sensitive to these structural alterations (Brown, 1973; Cody, 1985; MacArthur, 1965; Morris, 1973; Rosenzweig et al., 1975; Wiens, 1969). There are both short- and long-term effects of grazing on plant community species composition, primary production, and plant tissue quality. Belowground consumers can also be affected by the effects of grazing on soil water infiltration, nutrient cycling, carbon allocation patterns of plants, litter accumulation, and soil temperature. The overall effects of livestock on a particular component of the native fauna can be negative or can be positive through facilitative relationships (Gordon, 1988). In this chapter we assess the effects of cattle grazing on other above- and belowground consumers, on the diversity and relative sensitivity of these groups of organisms, and on their trophic structure. We first present some brief background information on plant communities of the shortgrass steppe and on the long-term grazing treatments in which many of the studies reported herein were conducted. Details on the plant communities are presented by Lauenroth in chapter 5 (this volume), grazing effects on plant communities by Milchunas et al. in chapter 16 (this volume); and grazing effects on nutrient distributions and cycling by Burke et al. in chapter 13 (this volume). The physiognomy of the shortgrass steppe is indicated in its name. The dominant grasses (Bouteloua gracilis and Buchloë dactyloides), forb (Sphaeralcea coccinea), and carex (Carex eleocharis) have the majority of their leaf biomass within 10 cm of the ground surface. A number of less abundant midheight grasses and dwarf shrubs are sparsely interspersed among the short vegetation, but usually much of their biomass is within 25 cm of the g round. Basal cover of vegetation typically totals 25% to 35%, and is greater in long-term grazed than in ungrazed grassland. Bare ground (more frequent on grazed sites) and litter-covered ground (more frequent on ungrazed sites) comprise the remainder of the soil surface (Milchunas et al., 1989).

Abstract:
Cheyenne conceptual artist Hachivi Edgar Heap of Birds makes word paintings, abstract paintings, and public art installations. This chapter considers Heap of Birds’s focus on memory, history, and community as central to his self and community-formulation. Through his artwork using image and text, he contributes to the ongoing project of decolonization: making visible a history of Native erasure and appropriating settler-colonial discourses of place and time, first steps in articulating a contemporary, collective, and sovereign Native identity.

Abstract:
Impact assessments increasingly rely on models to project the potential impacts of climate change on species distributions. Ecological niche models have become established as an efficient and widely used method for interpolating (and sometimes extrapolating) species’ distributions. They use statistical and machine-learning approaches to relate species’ observations to environmental predictor variables and identify the main environmental determinants of species’ ranges. Based on this estimated species–environment relationship, the species’ potential distribution can be mapped in space (and time). In this chapter, we explain the concept and underlying assumptions of ecological niche models, describe the basic modelling steps using the silvereye (Zosterops lateralis) as a simple real-world example, identify potential sources of uncertainty in underlying data and in the model, and discuss potential limitations as well as latest developments and future perspectives of ecological niche models in a global change context.

The conditions and characteristics of the nutrition of the golden bee-eater Meropsapiaster Linnaeus, 1758 (Coraciiformes, Meropidae) were studied in the conditions of forest-steppe landscapes of the Ulyanovsk region (Middle Volga region) during 2007–2019. The choice and preferences of the nest-suitable biotopes of the golden bee-eater are determined by the mechanical and geochemical composition of the soil - burrowing birds and sclerophiles, which include the golden-bee-eater, prefer dense and rather heavy soil for establishing nesting holes in the forest-steppe landscapes of the Ulyanovsk Reg

A current project is underway to create a prototype of an anatomically correct seagull with biologically accurate flight kinematics. The presented work is focused on the computational fluid dynamics (CFD) analysis of bird flight kinematics. A finite volume approach, using Fluent, was used to attempt to model the kinematics of bird flight with varying degrees of freedom to analyze the lift, drag, pressure, and vortices magnitude associated with a range of flight kinematics. Dimensional analysis has been performed to analyze the effects of angle of incidence on the different sections of a seagul

Platelets may become activated in a number of clinical disorders and participate in thrombus formation. We have developed a direct test for activated platelets in whole blood that utilizes dual-color flow cytometry and requires no washing steps. Platelets were distinguished from erythrocytes and white blood cells in the flow cytometer by labeling the platelets with biotin-AP1, an antibody specific for membrane glycoprotein lb, and analyzing the cells for phycoerythrin-streptavidin fluorescence. Membrane surface changes resulting from platelet activation were detected with three different FITC-

Abstract:
Platelet Activating Factor (PAF) is generally considered to play an important role in acute allergic reactions. A special example of such a reaction is allergic asthma and indirect evidence suggests that here too PAF may be involved. Direct proof for a role of PAF, however, is difficult to obtain since in blood PAF has an extremely short half-life due to its inactivation by an acetyl-hydrolase in plasma, its uptake and degradation by many cell types and its lipophilic properties making it easily stick to membranes. Despite these handicaps we report here that during an acute bronchoconstrictive

Abstract:
Very high-bypass ratio turbofans with large fan tip diameter are an effective way of improving the propulsive efficiency of civil aero-engines. Such engines, however, require larger and heavier nacelles, which partially offset any gains in specific fuel consumptions. This drawback can be mitigated by adopting thinner walls for the nacelle and by shortening the intake section. This binds the success of very high-bypass ratio technologies to the problem of designing an intake with thin lips and short diffuser section which is well matched to a low speed fan. Consequently the prediction of the mu

Shape Memory Alloys (SMAs) are active metallic materials classified as “smart” or “intelligent” materials along with piezoelectric ceramic and polymers, electro-active plastics, electro-rheological and magneto-rheological fluids and others. SMAs show a multitude of different and dependent properties interesting for technological applications. These properties depend on the peculiar deformation mechanisms, accounting for the so-called shape memory effect. SMAs are nowadays used in quite different fields, like thermo-mechanical devices, anti-loosening systems, biomedical applications, mechanical
