Animal Biotelemetry, 2017 Since the first studies in the mid-twentieth century, lightweight electronic tracking devices have been increasingly used to study waterfowl movements. With half a century of experience and growing sample sizes, it has become clear that the attachment of

c‐Rel–dependent Chk2 signaling regulates the DNA damage response limiting hepatocarcinogenesis
Hepatology, EarlyView., 2022 In response to genotoxic injury, c‐Rel upregulates ATM‐Chk2‐p53 pathway DNA damage proteins to limiting hepatocarcinogenesis. Abstract Background and Aims Hepatocellular carcinoma (HCC) is a leading cause of cancer‐related death. The NF‐κB transcription factor family subunit c‐Rel is typically protumorigenic; however, it has recently been reported as a

Applications of thermal imaging in avian science [PDF]
, 2013 Thermal imaging, or infrared thermography, has been used in avian science since the 1960s. More than 30 species of birds, ranging in size from passerines to ratites, have been studied using this technology.

Evidence that birds sleep in mid-flight
Nature Communications, 2016 Whether and how birds sleep during long-distance flights has remained a mystery. Here, Rattenborg and colleagues show for the first time that frigatebirds can sleep during flight, but do so in remarkably small amounts.

Journal of Field Ornithology, 2023 Although there is abundant evidence that migrant landbirds have modified their migratory timing in response to climate change, few studies have looked for evidence of long-term changes in site use or function, while even fewer studies have looked for ...

A forensic approach to understanding habitat use from stable isotope analysis of (avian) claw material [PDF]
, 2003 1. The potential of using stable isotope signatures of avian claws in order to infer diet and habitat use was investigated. 2. Highly significant relationships observed between stable carbon and nitrogen isotope ratios (<sup>13</sup>C, &

Analyzing time‐ordered event data with missed observations
Ecology and Evolution, 2017 A common problem with observational datasets is that not all events of interest may be detected. For example, observing animals in the wild can difficult when animals move, hide, or cannot be closely approached. We consider time series of events recorded

Frontiers in Endocrinology, 2023 In both captive and free-living birds, the emergence of the migratory phenotype is signalled by rapid and marked increases in food intake and fuelling, as well as changes in amount of nocturnality or migratory restlessness.

Stable isotope analysis provides new information on winter habitat use of declining avian migrants that is relevant to their conservation [PDF]
, 2012 Winter habitat use and the magnitude of migratory connectivity are important parameters when assessing drivers of the marked declines in avian migrants. Such information is unavailable for most species.
