Chimeric plumage coloration produced by ovarian transplantation in chickens

Poultry Science, 2013
Ovaries from Rhode Island Red donors were transplanted orthotopically into White Leghorn recipients. At maturation, recipients were mated with Rhode Island Red roosters to test the origin of their ovaries, using plumage coloration as a marker. A chick with chimeric plumage coloration was produced, indicating mechanisms that produce follicles with both ...

Animal‐mediated seed dispersal: A review of study methods

Applications in Plant Sciences, EarlyView.
Abstract By dispersing seeds, animals provide ecological functions critical for the ecology, evolution, and conservation of plants. We review quantitative and empirical approaches and emerging technologies to quantify processes and patterns of animal‐mediated seed dispersal (zoochory) across its phases: from predispersal to postdispersal.

Candidate pigmentation genes related to feather color variation in an indigenous chicken breed revealed by whole genome data

Frontiers in Genetics, 2022
Chicken plumage color is an inheritable phenotype that was naturally and artificially selected for during domestication. The Baicheng You chicken is an indigenous Chinese chicken breed presenting three main feather colors, lavender, black, and yellow ...

Variação intraespecífica da cor da pelagem de uma espécie de pequeno roedor sul-americano [PDF]

, 2016
Intra-specific color variation is often underestimated by researchers, and among mammalian species, intra-specific differences in coloration are poorly documented for most species.

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

The Anatomical Record, EarlyView.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Bird color and taxonomic diversity are negatively related to human disturbance in urban parks [PDF]

Web Ecology
Recently, studies have shown that highly urbanized areas are numerically dominated by birds with grey plumage, probably favoring camouflage with impervious grey surfaces.

Fasting and Refeeding Mediated Phospholipid Remodeling Plays an Important Role in Improving Meat Quality of Aged Laying Hens

Animal Research and One Health, EarlyView.
ABSTRACT This study explored fasting‐induced physiological remodeling effects on meat quality in aged laying hens. Fasting for 15 days (F15) significantly reduced abdominal fat, intermuscular fat width, subcutaneous fat thickness, and liver index versus pre‐fasting (F0) (p < 0.05), which recovered post‐refeeding.

Testes asymmetry, condition and sexual selection in birds: an experimental test [PDF]

, 1998
The functional significance of the marked directional asymmetry in testes size observed in many bird species is obscure. Møller suggested that (i) the smaller of the two testes serves a compensatory role and increases in size (and hence reduces ...

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.
