New records of moths (Insecta, Lepidoptera) from urban gardens on Terceira Island with new data on recently introduced species to the Azores [PDF]

open access: yes, 2018
The urban Duque da Terceira Garden, in the main town of Angra do Heroísmo (Terceira, Azores), was investigated to describe the species composition of moths (Insecta, Lepidoptera).

Movement ecology and sex are linked to barn owl microbial community composition. [PDF]

open access: yes, 2020
The behavioural ecology of host species is likely to affect their microbial communities, because host sex, diet, physiology, and movement behaviour could all potentially influence their microbiota.

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.

Wings of Coenagrion puella vary in shape at the northern range margin (Odonata: Coenagrionidae) [PDF]

open access: yes, 2008
A previous study has shown that wing size in Coenagrion puella varied considerably along a latitudinal gradient in the UK. Using landmark data from wing images, patterns of shape variation were also determined along the same transect by geometric ...

A detailed redescription of a skeletally immature ‘Redondasaurus’ suggests ontogenetic transformations in the taxon mirror phytosaurian morphological evolution

open access: yesThe Anatomical Record, EarlyView.
Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

Aspects of the biology of the Australasian harrier (Circus aeruginosus approximans Peale 1848) : a thesis presented for the degree of Master of Science by thesis only in Zoology at Massey University [PDF]

open access: yes, 1978
The study is based on 18 months intensive field-work during which 212 Australasian harriers were trapped, retrapped, measured, sexed, aged, individually marked and observed.

3D anatomical atlas of the heads of male and female adult Chamaeleo calyptratus

open access: yesThe Anatomical Record, EarlyView.
The veiled chameleon is a model organism in reptile development research. Utilizing contrast‐enhanced microCT and deep learning segmentation models, we have generated the first digital atlases of the skull, nervous system, cranial muscles and hyolingual muscles.

Morphometric wing variations in Fischer’s lovebirds (Agapornis fischeri) related to sex and age at 4–6 months

open access: yesJurnal Medik Veteriner
Wing morphometry plays a crucial role in avian functional ecology, influencing flight performance, energy efficiency, and sexual selection. However, quantitative data on wing development in lovebirds (Agapornis fischeri), remain scarce.

New genera and species of Lygaeoidea (Heteroptera: Lygaeoidea: Rhyparochromidae) [PDF]

open access: yes, 1998
Afralampes capensis is described as a new genus and species in the Megalonotini. The systematic position of Serranegra Lindberg is discussed, a new species is described from South Africa and a key to species included.

Anatomical bases of sex- and size-related acoustic variation in herring gull alarm calls [PDF]

open access: yes, 2014
The hypothesis that anatomical or physiological factors can constrain the production of vocalizations is supported by an increasing number of examples from a range of taxa, where acoustic variation is related to sex, body-size or condition. In this study,
