The impacts of biological invasions

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Molecular Detection of Toxoplasma gondii in Enclosures of African Primates (Papio papio and Papio hamadryas) at the Municipal Zoo of Bauru, São Paulo State, Brazil

open access: yesJournal of Medical Primatology, Volume 55, Issue 3, June 2026.
ABSTRACT Toxoplasmosis is one of the most prevalent parasitic infections in animals and humans worldwide, attracting the attention of many researchers who, in recent decades, have identified the sources of Toxoplasma gondii infections to optimize the adoption of preventive measures. In previous studies, it has been found that humans are infected mainly

Aminoacyl tRNA synthetases as potential drug targets of the Panthera pathogen Babesia

open access: yesParasites & Vectors, 2019
Background A century ago, pantheras were abundant across Asia. Illegal hunting and trading along with loss of habitat have resulted in the designation of Panthera as a genus of endangered species.

Asynchronous food-web pathways could buffer the response of Serengeti predators to El Niño southern oscillation [PDF]

open access: yes, 2013
Understanding how entire ecosystems maintain stability in the face of climatic and human disturbance is one of the most fundamental challenges in ecology.

Evolutionary and Ecological Determinants of the Phenology of Births in Wild Large Herbivores, a Systematic Review

open access: yesMammal Review, Volume 56, Issue 2, June 2026.
This semi‐systematic review supports the two dominant drivers of birth phenology: the seasonality and predation hypotheses. Even though there is evidence of their importance, the effects of female, offspring and population characteristics remain marginally accounted for. Asian and South and Central American species are currently understudied.

Livestock depredation by large carnivores in northern Botswana

open access: yesGlobal Ecology and Conservation, 2019
Human-carnivore conflict is a leading cause of large carnivore declines and minimizing these conflicts is vital to maintaining viable carnivore populations.

Big Cat Coalitions: A Comparative Analysis of Regional Brain Volumes in Felidae [PDF]

open access: yes, 2016
Broad-based species comparisons across mammalian orders suggest a number of factors that might influence the evolution of large brains. However, the relationship between these factors and total and regional brain size remains unclear.

No Evidence of Reactive Avoidance of Baboons (Papio ursinus and Papio anubis) to the Presence of Predators

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
In this study, we took advantage of the largest camera trap‐based monitoring project in Africa, Snapshot Safari and analyzed 10,000 camera trap detections from three sites in South Africa and one site in Tanzania to test whether baboons exhibit species‐specific reactive avoidance in response to the presence of predators. ABSTRACT Predators exert strong

Bioenergetic trophic trade‐offs determine mass‐dependent extinction thresholds across the Cenozoic

open access: yesEcology, Volume 107, Issue 5, May 2026.
Abstract Body size constrains trophic interactions, shaping the feasibility of species' populations. Over macroevolutionary timescales, these constraints feed back to shape selection on body size and diet. We develop a bioenergetic, three‐level trophic framework—typical of terrestrial mammalian ecosystems—to explore how bioenergetic trade‐offs emerging
