The orchid bee genus Euglossa contains more than 100 species distributed throughout the Neotropics from Paraguay to Mexico (Michener, 2000). Most species nest in protected cavities such as in logs, trunks, small cavities between rocks, and man-made constructions, but some species build their nests in exposed sites where they are attached to small branches or underneath leaves (Eberhard, 1988; N...

Phenotypic sex in sea turtles is determined by nest incubation temperatures, with warmer temperatures producing females and cooler temperatures producing males. The common finding of highly skewed female-biased hatchling sex ratios in sea turtle populations could have serious repercussions for the long-term survival of these species and prompted us to examine the thermal profile of a relatively...

—The effects of habitat and vegetation characteristics on the reproductive success of Yellowbreasted Chats (Icteria virens) were examined in central Kentucky. During the 1998 breeding season, 49 nests were located and monitored and the characteristics of nest sites and territories determined. Habitats where nests were located were categorized as old field, linear, or clump, and nests were class...

Ground-nesting ducks can reduce nest depredation by selecting sites where local physical structures or vegetation provide olfactory visual concealment. We evaluated nest-site selection comparing duck nests to random during 2019 and 2020 in the impounded wetlands of Great Salt Lake (GSL), Utah, USA. During wet springs, most are underwater, leaving only dams available as nesting substrate. locate...

Modification, fragmentation and loss of boreal forest habitats have been intensive during the last century due to forestry practises land use. This has related population declines many species, yet mechanisms affecting on background are largely unknown. The willow tit, a primary cavity-nesting species that was once 4th most common bird in Finland is nowadays endangered. Earlier findings suggest...

Abstract Elucidating bee response to urbanization is essential promoting pollinator diversity in cities especially considering such landscapes are projected expand support future global populations. To determine how community composition and plant–pollinator interactions respond urbanization, 29 sites representing three urban categories (high, medium low urbanization) were monitored biweekly fr...

Abstract Aim Quantifying the importance of habitat areas for conservation highly migratory marine species with complex life histories can be challenging. For example loggerhead turtles ( Caretta caretta ) nesting in Japan forage both oceanically and neritically after their reproductive period. Here, we aimed to quantify proportions using these two contrasting habitats (foraging dichotomy) sugge...

This paper presents the performance improvement method for vessel nesting processing. Within nesting processing, three functions are inserted. Trim connecting two objects is to improve the nesting processing speed. Polyline creating a single object from multiple selecting objects is also to improve the nesting processing speed. Overline removing the overlapped parts is to improve the speed and ...

Understanding how predators respond to fluctuations in prey density has important conservation andmanagement implications, particularly for threatened and endangered specialists. However, directly linking prey densities to predator behavior and demography over broad spatial and temporal scales is rare, in part, because it can be prohibitively expensive and time-consuming to quantify prey densit...

Williamson's sapsuckers (Sphyrapicus thyroidem) have narrow habitat requirements and are sensitive indicators of change in intensively managed forest habitats of western North America. Thus, we studied habitat suitability for Williamson's sapsuckers at 99 4-ha sites (33 nest sites, 66 non-use sites) in mixedconifer forests in Arizona during 1991. Nesting success of sapsuckers was high in this h...
