Limited Effects of Temperature on Captive Eastern Hellbender (Cryptobranchus alleganiensis alleganiensis) Growth

open access: yesZoo Biology, EarlyView.
While higher temperatures are generally expected to increase amphibian growth, our experiments with captive‐reared Eastern Hellbenders found no evidence that growth increased at a rearing temperature of 21°C relative to 16°C. As Eastern Hellbender reintroduction efforts move forward, a focus on other conditions, such as density or diet, might be more ...

Effects of Density and Food Availability on the Growth of Captive‐Reared Eastern Hellbenders

open access: yesZoo Biology, EarlyView.
Our experiments demonstrate that food is the major factor limiting captive‐reared Hellbender growth and that increasing rearing density to the tested levels does not negatively impact growth. Implementing these changes may result in larger, more robust Hellbenders and increase the success of reintroduction programs.

The Greatest Show (Birds) on Earth: Public Presentations and Their Welfare Impacts on Zoo‐Housed Birds

open access: yesZoo Biology, EarlyView.
Birds involved in bird shows were compared against non‐show birds regarding show paticipation, behaviour, body score condiiton, and feather condition. Additionally, comparisons between on and off show days as well as before and after the show were made to investigate differences in behaviour and condition. Show birds demonstrated a closer to ideal body

Radiographic Screening of Wild and Semi‐Wild Cape Ground Squirrels (Geosciurus inauris) for the Presence of Peri‐Apical Masses Associated With Elodont Incisor Teeth

open access: yesZoo Biology, EarlyView.
Peri‐apical masses were absent in both wild and semi‐wild Cape ground squirrels, despite dietary differences and minor incisor trauma. These findings suggest such lesions are rare outside captivity and not induced by low‐fiber diets alone, adding to the literature on environmental and dietary risk factors in elodont tooth pathology.

Deep blueprint: A literature review and guide to automated image classification for ecologists

open access: yesJournal of Animal Ecology, EarlyView.
A practical, literature‐grounded review that gives ecologists a clear, modular workflow for deep learning image classification. With code, GUIs and a novel deep sea case study (automated deep sea biotope classification) it lowers technical barriers and provides a usable blueprint for accelerating, standardising, and scaling ecological image analysis ...

Conceptualizing moral migration: how disillusionment and the transnational right motivate migration to Russia Conceptualiser la migration morale : comment les désillusions et la droite transnationale motivent l’émigration vers la Russie

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
Russia is consistently a top migration destination. While most migrate to Russia from other post‐Soviet countries, a small but highly visible group of the Russian‐speaking diaspora has returned from Europe and North America. Lauded in Russian media as ‘ideological migrants’, their narratives at first glance echo those of the state as they claim to flee

Unraveling Occurrence Patterns and Diversity of Avian Malaria Parasites in Iberian Obligate and Facultative Scavenger Birds

open access: yesIntegrative Zoology, EarlyView.
Low overall haemosporidian occurrence (3.4%; 13/383). Unexpected high lineage diversity (10 new host–parasite interactions). Novel Leucocytozoon lineage (GYPBAR01) in all European vultures except the griffon vulture. Plasmodium relictum (lineage SGS1) in adult red kites.

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

open access: yesIntegrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

The place of cooperation in the region food provision

open access: yesRUDN Journal of Agronomy and Animal Industries, 2009
One of the most real and effective way to provide stable growth of agrarian production in private plots and farm plots and creation of correspondent infrastructure is the development of all forms of cooperation in the region.
