Loss, persistence and reversal of phenotypic traits

Biological Reviews, EarlyView.
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

PHYSIOLOGICAL RESPONSE OF PULLET CHICKS FED DIETS CONTAINING Moringa oleifera, Ocimum gratissimum and Vernonia amgydalina LEAF MEAL-BASED DIETS

Nigerian Journal of Animal Production
Blood reflects the pathological status of animals exposed to toxicants and other conditions. Blood examination helps to clinically investigate the presence of metabolites and other constituents in the body of animals and plays vital roles in the ...

Humans are not unique: difficult birth is common in placental mammals

Biological Reviews, EarlyView.
ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult

Does seasonal variation in the corticosterone response affect the nutritional ecology of a free-ranging lizard?

Journal of Animal Ecology
Challenging events in the environment that are both predictable (e.g. seasonal patterns in breeding activities) and unpredictable (e.g. predator encounter) are known to induce a glucocorticoid response that facilitates metabolic requirements during the ...

On the importance of including both sexes in animal studies – insights from home‐cage monitoring

Biological Reviews, EarlyView.
ABSTRACT A review of behavioural studies using home‐cage monitoring (HCM) systems revealed that over 61% of studies used only male subjects, with only 24% including both sexes, despite evidence of substantial behavioural differences between male and female animals. This bias could influence the outcomes of biomedical research.

Evidence for adaptive explanations of semelparity in animals

Biological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Semi-Purified Egg-White Protein (EWP) Diet Improves Nutritional Status and Maintains Adequate Blood Pressure in Dahl Salt-Sensitive (Dahl-SS) Rats

Animal and Veterinary Sciences
Standardized diets for laboratory rodents become increasingly important. Dietary imbalances can negatively impact experimental outcomes. Commercially available diets often include ingredients that cannot be experimentally manipulated and may not meet all

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

Biological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

Determining the Nutritional Potential of Ancient Wheat Species: A Closer Look at Starch and Protein Digestibility, and Phenolic Acid Content

Cereal Chemistry, EarlyView.
ABSTRACT Background and Objectives The recent trend towards healthy food choices and sustainable agriculture has revived interest in underutilized wheat species such as emmer, einkorn, and spelt. Given these developments, the objective of the study was to compare the differences in chemical composition and digestibility characteristics among ...

Performance of Body Condition Score (BCS) and Physiological Parameters of Etawa Crossbred Goats under Intensive and Semi-Intensive Rearing Systems

Bulletin of Applied Animal Research
Etawah Crossbred Goats (PE) represent a promising genetic resource for meat production due to their high adaptability and productivity. The Body Condition Score (BCS) serves as a practical indicator for assessing fat reserves and management quality ...
