Body mass and sex estimation from lower carnassial tooth morphometry in the endangered Iberian wolf (Canis lupus signatus): An ecomorphological analysis of sexual size dimorphism

open access: yesThe Anatomical Record, EarlyView.
Abstract The Iberian wolf (Canis lupus signatus) is an endangered subspecies characterized by highly fragmented populations and increasing human–carnivore conflict across the Iberian Peninsula. Although body mass strongly influences predator–prey dynamics and ecological performance, quantitative assessments of sexual size dimorphism (SSD) and body mass

THE ART OF WAR: PATTERNS AND MECHANISMS UNDERLYING PREDATOR-INDUCED PLASTICITY OF AMPHIBIANS [PDF]

open access: yes, 2013
Organisms often employ phenotypic plasticity as a strategy to cope with variable environments. This is particularly true of predation threats, wherein prey induce defenses to reduce detection or capture by predators.

Redescription of †Eobrasilia coutoi (Metatheria: Polydolopimorphia), a unique sclerocarpophagous metatherian from the Palaeogene of South America: Systematic affinities, and paleoecological and evolutionary implications

open access: yesThe Anatomical Record, EarlyView.
Abstract The ‘Palaeogene strata’ of the Itaboraí Basin (upper Paleocene‐lower Eocene), Southeastern Brazil, has preserved 29 genera and almost 50 species of metatherians (about 65% of its mammalian diversity). Among them, Eobrasilia coutoi Simpson, 1947 is the most enigmatic due to its quite fragmentary nature.

Modeling and analysis in a prey-predator system with commercial harvesting and double time delays [PDF]

open access: yes, 2016
A differential-algebraic prey-predator system with commercial harvesting on predator is proposed, where maturation delay for prey and gestation delay for predator are considered.

First Record of Tasmanian Devils in the Pilbara: Late Quaternary Subfossils From Juukan Gorge, Puutu Kunti Kurrama Country, and Insights Into Human—Faunal Relationships and Extinction

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT This study presents the first unequivocal evidence for the presence of Tasmanian devils (Sarcophilus harrisii) in the Pilbara region of northwestern Australia, based on material recovered from archaeological excavations at Juukan Gorge on Puutu Kunti Kurrama and Pinikura country.

Use of Clotrimazole in Finfish Aquaculture: Mechanistic Insights, Limitations, and Future Directions for Antifungal Therapy

open access: yesAnimal Research and One Health, EarlyView.
This review critically evaluates clotrimazole as a potential antifungal for finfish aquaculture, highlighting strong mechanistic and in vitro efficacy against aquatic mycoses alongside major gaps in in vivo evidence, toxicokinetics, residue safety, and environmental risk, outlining priorities for responsible therapeutic development and regulatory ...

Global Stability and Hopf Bifurcation for Gause-Type Predator-Prey System

open access: yesJournal of Applied Mathematics, 2012
A class of three-dimensional Gause-type predator-prey model is considered. Firstly, local stability of equilibrium indicating the extinction of top-predator is obtained.

Fecal Virome Transplantation in Human Disease and Livestock Production: Evidence, Mechanisms, and Translational Challenges

open access: yesAnimal Research and One Health, EarlyView.
Fecal virome transplantation may reshape bacterial communities and host responses while reducing viable bacterial transfer. Preclinical evidence suggests biological activity, but human efficacy remains uncertain, and translation requires product standardization, causal validation, donor–recipient matching, and rigorous biosafety assessment.

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.

The environmental dependence of ecological interaction networks

open access: yesBiological Reviews, EarlyView.
ABSTRACT Interactions between species are often assumed to occur whenever species pairs co‐occur, allowing us to reconstruct local ecological networks from a deterministic ‘metaweb’. Over the past few years, an increasing number of papers have called for a reassessment of this simplistic assumption.
