The primitive giant panda Kretzoiarctos beatrix (Carnivora, Ursidae) from the hominid locality of Hammerschmiede: dietary implications

Papers in Palaeontology, Volume 10, Issue 5, September/October 2024.
Abstract Extant giant pandas are among the most herbivorous forms of the order Carnivora, feeding mainly on hard plant material. The first steps of their evolutionary lineage are of particular interest for our understanding of the factors that led to this specialized niche.

Morphological disparity of mammalian limb bones throughout the Cenozoic: the role of biotic and abiotic factors

Palaeontology, Volume 67, Issue 4, July/August 2024.
Abstract Mammals exhibit ecology‐related diversity in long bone morphology, revealing an ample spectrum of adaptations both within and between clades. Their occupation of unique ecological niches in postcranial morphology is thought to have occurred at different chronological phases in relation to abiotic factors such as climate and biotic interactions

Ghostbusting—Reducing bias due to identification errors in spatial capture‐recapture histories

Methods in Ecology and Evolution, Volume 15, Issue 6, Page 1060-1070, June 2024.
Abstract Identifying individuals is key to estimating population sizes by spatial capture–recapture, but identification errors are sometimes made. The most common identification error is the failure to recognise a previously detected individual, thus creating a ‘ghost’ Johansson. This results in positively biased abundance estimates.
