Frontiers in Ecology and Evolution, 2023 Teeth are often the first structures that anatomists and paleontologists examine to understand the ecology and morphology of feeding, both because teeth are highly specialized structures that provide precise information, and because they are among the ...

Systematic Entomology, Volume 50, Issue 3, Page 630-645, July 2025.We describe †Cretovelona orussopteryx n. gen. & sp. from Kachin amber. The fossil is examined with synchrotron scanning and integrated into an existing morphological data set for Orussoidea. This fossil parasitoid wasp displays a unique character combination demonstrating intermediate conditions in evolving the complex features employed in echo ...

EFSA Journal, Volume 23, Issue 7, July 2025.Abstract The emergence of highly pathogenic avian influenza (HPAI) A(H5N1), clade 2.3.4.4b, genotype B3.13 in U.S. dairy cattle marks a significant shift in the virus' host range and epidemiological profile. Infected cattle typically exhibit mild clinical signs, such as reduced milk production, mastitis and fever, with morbidity generally below 20% and

Establishing death in stranded Odontocetes (toothed whales) using other mammals : a pilot study : a thesis presented in partial fulfillment of the requirements for the degree of Master of Science in Zoology at Massey University [PDF]
, 2003 The aim of this study was to investigate and evaluate a new method for determining death in stranded odontocetes (toothed whales). The new method was using the pulsations seen in the retinal blood vessels in the place of the heart rate. The retinal blood

International Review of Hydrobiology, Volume 110, Issue 1, Page 13-21, June 2025.ABSTRACT River dolphins are the least studied and most threatened cetaceans. Anthropogenic activities, including habitat fragmentation, pollution, and declining fish stocks, pose significant challenges to their survival. This study evaluated the effects of landscape changes resulting from human activity on the encounter rates of the putative species of

Darwin and evolution: a set of activities based on the evolution of mammals [PDF]
, 2010 These activities, prepared for key stage 5 students (ages 16-18) and also suitable for key stage 4 (ages 14-16), show that physical appearance is not necessarily the best way to classify mammals.
