Humans and platyrrhines share a pattern of articular variance

open access: yesThe Anatomical Record, EarlyView.
Abstract Previous work has identified a pattern of articular shape variation in modern human limb joints, in which convex joint surfaces exhibit constrained variance relative to their more variable concave conarticulars. This pattern is notable given that joint morphogenesis is influenced by local biomechanical environments, which vary substantially ...

Comparative histological, histochemical, and histometric evaluation of the esophagus in two avian species with different feeding habits (Ciconia ciconia and Buteo buteo)

open access: yesThe Anatomical Record, EarlyView.
Histological structure of esophagus. Abstract The aim of this study was to conduct a comparative evaluation of the histological and histochemical organization of the esophagus in two avian species with different feeding ecologies. A total of 6 individuals were used for this purpose (3 storks, 3 common buzzards).

Evaluating Bergmann's and Allen's rules in the long bones of the eastern gray squirrel

open access: yesThe Anatomical Record, EarlyView.
Abstract Ecogeographical rules predict variation in body size and appendage proportions across climatic gradients, yet intraspecific tests using long bones from wild populations remain limited among small mammals. This study tests the hypothesis that eastern gray squirrels (Sciurus carolinensis) conform to Bergmann's rule, that is, body size increases ...

Remote sensing of Antarctic polychaete reefs (Serpula narconensis): reproducible workflows for quantifying benthic structural complexity with action cameras, remotely operated vehicles and structure‐from‐motion photogrammetry

open access: yesRemote Sensing in Ecology and Conservation
Quantifying the structural complexity provided by biogenic habitat structures is important in ecology, conservation and management, and yet remains a challenging task, particularly in deep sea and polar environments, that current photogrammetry tools can

Ecological and Habitat Restoration for Insect Conservation

open access: yes
Ecological restoration, the process of assisting the recovery of an ecosystem, can benefit insect conservation. The restoration of native plant species is often associated with natural recovery of insects, firstly phytophagous and pollinators. Restoration can also specifically aim at assisting the recovery of a particular insect taxon: meadows reopened

Development of the nasal capsule in Emydura subglobosa (Testudines: Pleurodira) with a comparison to other turtles

open access: yesThe Anatomical Record, EarlyView.
Abstract Extant turtles occupy freshwater, marine, and terrestrial habitats, and their nasal region provides important evidence for the evolution of respiration‐ and sensory‐related cranial morphology. However, developmental data on the turtle nasal capsule remain limited, particularly in Pleurodira.

Factors affecting distribution and habitat selection of water shrews Neomys fodiens [PDF]

open access: yes, 2012
The water shrew Neomys fodiens is one of Britain’s least known mammals and its habitat requirements are poorly understood. The purpose of this study was to determine occurrence and associated habitat preferences of water shrews, a species of conservation

Morphological description of the oropharyngeal cavity of Kinosternon scorpioides scorpioides (Linnaeus, 1766), (Testudines: Kinosternidae)

open access: yesThe Anatomical Record, EarlyView.
Gross morphology, Light Microscopy and Scanning Electron Microscopy revealed the structural organization of the oropharyngeal cavity of Kinosternon scorpioides scorpioides, characterized by mucous epithelium, epithelial pores, and developed lingual papillae.

Preference of trees for nest building by critically endangered white‐rumped vultures (Gyps bengalensis) in Nepal

open access: yesEcology and Evolution
White‐rumped vultures (Gyps bengalensis) are critically endangered species, and protecting their habitats, particularly the nesting trees, may have a positive impact on their reproductive success.
