Uncertainty in identifying local extinctions: the distribution of missing data and its effects on biodiversity measures [PDF]
, 2016 Identifying local extinctions is integral to estimating species richness and geographic range changes and informing extinction risk assessments. However, the species occurrence records underpinning these estimates are frequently compromised by a lack of ...

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade
Biological Reviews, EarlyView.ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...

The draft genome of the Temminck’s tragopan (Tragopan temminckii) with evolutionary implications
BMC Genomics, 2023 Background High-quality genome data of birds play a significant role in the systematic study of their origin and adaptive evolution. The Temminck’s tragopan (Tragopan temminckii) (Galliformes, Phasianidae), a larger pheasant, is one of the most abundant ...

Digital Surveillance: A Novel Approach to Monitoring the Illegal Wildlife Trade [PDF]
, 2012 A dearth of information obscures the true scale of the global illegal trade in wildlife. Herein, we introduce an automated web crawling surveillance system developed to monitor reports on illegally traded wildlife. A resource for enforcement officials as

Haptoglobins In Some Galliformes Birds
Poultry Science, 1977 In several groups of galliform birds (chicken, turkey, pheasant and guinea fowl) the presence and function of plasma haptoglobin (Hp) have been studied. Paper, acetate and starch-gel electrophoresis were carried out and two benzidine stain regions were observed when haemoglobin (Hb) was added to normal plasma (Hb-Hp complex and methemalbumin) besides ...

Ecography, EarlyView.The abundance center hypothesis (ACH) posits that species abundance peaks at distribution centers; however, empirical support remains inconsistent. This study tested the generality of the ACH and investigated species traits as mediators of abundance–distance relationships.

"So bigge as bigge may be": tracking size and shape change in domestic livestock in London (AD 1220-1900) [PDF]
, 2013 This study presents the analysis of 7966 individual cattle, sheep, pig and domestic hen bone measurements from 105 sites excavated in London dating to the period AD 1220–1900. Multiple episodes of size change are identified, although the speed and timing

, 2018 Galliformes and columbifomes are closely associated with humans and some species have been domesticated for well over 5000 years. Both orders remain diverse, ranging from the common domestic poultry species (e.g., chicken, turkey, and squabs) to the more exotic species found in the wild and in zoological collections.

International Journal of Osteoarchaeology, EarlyView.ABSTRACT The golden eagle (Aquila chrysaetos) nests in rock cavities where it accumulates prey bone remains during the breeding season. Because nests can be reoccupied from year to year, these faunal elements can form remarkable bone accumulations and, in the sub‐fossil record, be mixed with assemblages derived from human or other predator activities ...
