Equilibria and oscillations of magnetised neutron stars

open access: yes, 2010
We investigate equilibrium configurations and oscillation spectra of neutron stars,modelled as rotating magnetised fluid bodies in Newtonian gravity. We also explorethe idea that these model neutron stars could have dynamics analogous to rigid-bodyfree ...

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

open access: yesBiological Reviews, Volume 101, Issue 5, Page 2214-2239, October 2026.
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

Evaluating machine learning models for multi‐species wildlife detection and identification on remote sensed nadir imagery in South African savanna

open access: yesWildlife Biology, Volume 2026, Issue 5, September 2026.
This research paper investigates the efficacy of leading machine learning (ML) models for detecting and identifying ungulate species in African savanna using nadir imagery from unmanned aerial vehicles (UAVs). Traditional aerial counting methods, while widely used, suffer from significant limitations in accuracy and precision, in part due to human ...

Pickin' up good vibrations: a systematic review of footfall detection and analysis in the realm of wildlife surveying

open access: yesWildlife Biology, Volume 2026, Issue 5, September 2026.
Exploration of new wildlife surveying methodologies that leverage advances in sensor technology and machine learning has led to tentative research into the application of seismology techniques. This, most commonly, involves the deployment of a footfall trap – a seismic sensor and data logger customised for wildlife footfall.

Contrasting properties of predation and scavenging networks governed by megaherbivores in an African savannah

open access: yesJournal of Animal Ecology, Volume 95, Issue 9, Page 1656-1671, September 2026.
For the first time, predation and scavenging networks are directly compared within a single ecosystem. Using an 8‐year dataset of African mammals, including megaherbivores, this study reveals distinct structural rules and body mass constraints, providing a scalable framework for studying consumer–resource dynamics and ecosystem function.

Elephant Rewilding Indirectly Affects Rodent Site‐Use and Behavior by Moderating Coarse Woody Debris Density

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
Megaherbivores such as African savannah elephants are ecosystem engineers that modify vegetation structure, yet the cascading effects of these changes on smaller fauna remain poorly understood. We examined how elephant rewilding affected coarse woody debris (CWD) density and the behavior of the Natal multimammate mouse in lowveld savannah, South Africa,

Encroachment on Water Corridors Drives Farmers–Giraffe Conflicts Along River Tana Ecosystem in Eastern Kenya

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
Human–wildlife conflict in Garissa County, Kenya, is intensified by the degradation of historical water corridors, driven mainly by Prosopis juliflora invasion, farmland expansion, and riverbank erosion. This study identifies conflict hotspots near water sources and croplands, and shows that supplementary feeding effectively reduces giraffe incursions ...

Chromospherically Active Stars. XVII. The Double-lined Binary 54 Camelopardalis (AE Lyncis) [PDF]

open access: yes, 1998
New spectroscopic observations of the double-lined chromospherically active binary 54 Camelopardalis (=AE Lyncis) have been obtained, resulting in improved orbital elements and the determination of the fundamental properties of the system.

Three Decades of Monitoring Reveal That Differing Population Trends of Large Herbivores in Gonarezhou National Park, Zimbabwe, Are Related to Species Body Mass

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
For ~20 years after the severe 1992 drought, the estimated numbers of elephant, buffalo, eland, giraffe, greater kudu, nyala, warthog, waterbuck, wildebeest and zebra increased in Gonarezhou NP, Zimbabwe. After 2013/2014, the rate of change in the survey estimates declined for buffalo, eland, elephant, giraffe and zebra, but was not negative ...

RR Lyrae stars in the GCVS observed by the Qatar Exoplanet Survey [PDF]

open access: yes, 2015
This publication was made possible by NPRP grant # X-019-1-006 from the Qatar National Research Fund (a member of Qatar Foundation). AAF is grateful to DGAPA-UNAM for grant number IN104612.We used the light curve archive of the Qatar Exoplanet Survey to ...
