Nest box use by American Kestrels and other cavity-nesting birds during the nonbreeding season
Avian Conservation and Ecology, 2017 Nest boxes are posted to provide breeding sites for cavity-nesting birds but less is known about their function in the nonbreeding season, when nest boxes may become important roost sites.

Raptor hunted by caspases [PDF]
Cell Death & Disease, 2016 Emergence of survival strategies is a key step for organisms during evolution. The capacity to adapt from nutrient-rich to nutrient-poor environments led to the appearance of protein complexes regulating anabolic and catabolic pathways. The evolutionarily conserved kinase mTOR (mechanistic target of rapamycin) emerged as a crucial and central protein ...

Integrative Conservation, EarlyView.This study reconstructs the phylogeny of the Javan Hawk‐Eagle (Nisaetus bartelsi) within the subfamily Aquilinae using Maximum Likelihood and Bayesian Inference algorithms on a blood sample and GenBank data. The analysis reveals that the sampled genus Nisaetus forms a monophyletic group. Furthermore, N. bartelsi occupies a sister‐taxon of N.

Critically assessing the utility of portable lead analyzers for wildlife conservation
Wildlife Society Bulletin, 2018 Lead (Pb) exposure in wildlife is a widespread management and conservation concern. Quantitative determination of Pb concentrations in wildlife tissues is the foundation for estimating exposure and risk.

Repeated large scale loop migrations of an adult European Honey Buzzard
Avocetta, 2019 During migration, birds adopt flight strategies that often differ between spring and autumn. This behaviour can lead to differences in migratory paths as well as in-flight performances between seasons and may help to explain seasonal differences in the ...

Journal of Quaternary Science, EarlyView.ABSTRACT While competition with large carnivores is likely to have shaped Middle Paleolithic hominins' subsistence behavior, palimpsested human and carnivore accumulations render the signal challenging to isolate. This study presents a detailed zooarchaeological and taphonomic analysis of a non‐anthropogenic faunal assemblage from a MIS 5 (~130–80 ka ...

Raptor Swoops in on Metabolism [PDF]
Cell Metabolism, 2008 The mammalian target of rapamycin (mTOR) serine/threonine kinase plays a central role in insulin signaling and cell growth, through two distinct complexes with its subunits raptor or rictor. In this issue, two reports utilizing tissue-specific knockout mice detail key roles for mTORC1 in skeletal muscle and adipose tissue function.

International Journal of Osteoarchaeology, EarlyView.ABSTRACT During the transition from the Pleistocene to the Holocene, hunter‐gatherer societies in the northeastern Iberian Peninsula increased the number of settlements and broadened their subsistence strategies. This period is marked by the appearance of terrestrial snail accumulations attributable to human harvesting, the expansion of specialized ...

Oikos, EarlyView.Annual survival is a key demographic parameter driving population trends in wildlife populations. However, despite numerous species‐specific or regional studies, global reviews of the factors affecting the survival of declining taxa remain scarce. Here, we investigated annual survival of fledged immature and adult shorebirds, a globally‐distributed and
