Host life-history strategies and the evolution of chick-killing by brood parasitic offspring [PDF]

open access: yes, 2008
Nestling brood parasites vary in the harm that they do to their companions in the nest. Here we use a game-theoretical model to attempt to account for this variation.

Integration of Nutrition and Organic Agriculture Framework in Managing Gastrointestinal Nematodes in Ruminants

open access: yesAnimal Research and One Health, EarlyView.
Gastrointestinal nematode infections damage the gastrointestinal epithelial tissues of ruminants, affecting nutrient utilization and overall production performance. This review outlines host‐gastrointestinal nematode interactions and discusses integrated control strategies, including nutritional supplementation, grazing management, vaccines, and ...

Gut Health in Ostriches (Struthio camelus): Insights Into Intestinal Structure, Functions, Microbiome, and Improvement Strategies

open access: yesAnimal Research and One Health, EarlyView.
Our paper systematically reviews the intestinal structure, function, and microbiota of ostriches, along with strategies for improving their gut health. We analyze how these factors collectively influence intestinal homeostasis and ostrich welfare, emphasizing probiotics as a promising intervention to enhance gut health, boost population well‐being, and

Beyond antimicrobials: Ecological nano‐strategies for rebalancing dysbiotic oral microbial homeostasis

open access: yesBMEMat, EarlyView.
Oral microbial homeostasis, a dynamic host‐microbe balance, is vital in infectious diseases. Conventional antibiotics often disrupt this homeostasis, spurring interest in nanomaterials for oral microbial homeostasis rebalancing. This review outlines nanomaterial strategies across three ecological levels (population/community, ecosystem, and cross ...

Tracking Varroa Parasitism Using Handheld Infrared Cameras: Is Eusocial Fever the Key?

open access: yesInsects
The Varroa destructor is the most significant bee parasite and the greatest threat to bee health all around the world. Due to its hidden lifestyle, detection within the brood cell is only possible through invasive techniques.

Evidence for adaptive explanations of semelparity in animals

open access: yesBiological 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 ...

Ejecting chick cheats: a changing paradigm?

open access: yesFrontiers in Zoology, 2011
Evolutionary arms-races between avian brood parasites and their hosts have typically resulted in some spectacular adaptations, namely remarkable host ability to recognize and reject alien eggs and, in turn, sophisticated parasite egg mimicry.

Mobbing and sitting tight at the nest as methods of avoiding brood parasites

open access: yes, 2012
The arms race between brood parasites and their hosts has led to many different host behaviours for avoiding parasitism. Some of these behaviours are social, and require the presence of conspecifics to work effectively: in response to alarm calls, some ...

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

open access: yesBiological 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.

Food‐solicitation displays in nestling birds: still begging for answers

open access: yesBiological Reviews, EarlyView.
ABSTRACT Nestling begging is a key model for understanding animal communication and parent–offspring conflict. Dynamic begging displays are often interpreted as costly, honest signals of need, with honesty maintained by viability costs, as proposed in Godfray's influential signalling model.
