Broadening the semiaquatic scene: Quantification of long bone microanatomy across pinnipeds

open access: yesThe Anatomical Record, EarlyView.
Abstract Investigations of bone microanatomy are commonly used to explore lifestyle strategies in vertebrates. While distinct microanatomical limb bone features have been established for exclusively aquatic and terrestrial lifestyles, identifying clear patterns for the semiaquatic lifestyle remains more challenging.

Garbage in the diet of carnivores in an agricultural area [PDF]

open access: yes, 2016
Human food waste is considered to be richer in carbohydrates, lipids and proteins than most natural food supplies; however, it is very well digested in scats. So, as an indication of this kind of food in the diet, we have used each indigestible,

Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)

open access: yesThe Anatomical Record, EarlyView.
Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.

A new basal caniform (Mammalia: Carnivora) from the middle Eocene of North America and remarks on the phylogeny of early carnivorans. [PDF]

open access: yesPLoS ONE, 2011
Despite a long history of research, the phylogenetic origin and initial diversification of the mammalian crown-group Carnivora remain elusive. Well-preserved fossil materials of basal carnivorans are essential for resolving these issues, and for ...

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, EarlyView.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Rodent monocyte‐derived macrophages do not express CD163: Comparative analysis using macrophages from living boreoeutherians

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background CD163 is a scavenger receptor predominantly expressed on the surfaces of macrophages in various mammalian species and is a marker of anti‐inflammatory (M2‐like) macrophages. High density of CD163‐positive tumor‐associated macrophages (TAMs) is associated with worse prognosis in various patient tumors.

Comparison of Lagostomus maximus amelogenin gene (AMELX) with other mammals [PDF]

open access: yes, 2016
The aim of this study was to compare the Lagostomus maximus AMEL sequence to assess their similarity with the AMEL genes from other mammals. Previously we reported a sequence of the AMEL gene of Lagostomus maximus which corresponds to the intron 3 of the

Unveiling human–wildlife interactions in the context of livestock grazing abandonment and the return of large carnivores, ungulates and vultures: A stakeholder perspective

open access: yesPeople and Nature, EarlyView.
Abstract Pastoral practices remain a widespread economic activity across European mountain regions. However, the viability of this activity may be threatened by the recovery of large wild vertebrates associated with passive rewilding, leading to the so‐called human–wildlife conflicts.

Shifts in cranial integration associated with ecological specialization in pinnipeds (Mammalia, Carnivora)

open access: yesRoyal Society Open Science, 2019
Patterns of trait integration reflect the underlying genetic and developmental architecture of morphology and significantly influence the direction of evolution.

More pumas (Puma concolor) does not change perceptions: The mismatched response of ranchers to the presence of a top carnivore

open access: yesPeople and Nature, EarlyView.
Abstract Human‐wildlife conflicts (HWCs) are one of the most critical conservation challenges worldwide. Large carnivores are frequently at the centre of these conflicts because of the perceived and real threats they pose to livestock and human safety.
