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

Wildlife Biology, EarlyView.
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

Wildlife Biology, EarlyView.
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.

First Vasectomy Procedure Successfully Performed on a Southern African Male Giraffe (Giraffa camelopardalis giraffa)

Zoo Biology, EarlyView.
First successful vasectomy in a southern African male giraffe, Giraffa camelopardis giraffa ABSTRACT This study reports the first successful vasectomy on a southern African male giraffe (Giraffa camelopardalis giraffa). The goal of the procedure was to create a teaser male for reproductive studies.

Monitoring African Megafauna in an Anthropogenic Landscape: A 15‐Year Case Study of the Vulnerable West African Giraffe

Animal Conservation, EarlyView.
We used pattern recognition software to correct misidentifications in a 15‐year photographic database of the last, vulnerable West African giraffe population in Niger. After revealing substantial methodological errors that had inflated population estimates by nearly 19%, we corrected individual encounter histories and applied capture‐mark‐recapture ...

Perceived costs as drivers of wildlife management preferences in rural Tanzanian communities

Conservation Biology, EarlyView.
Abstract Effectively managing human–wildlife interactions is crucial for fostering coexistence on shared landscapes. Management options are most effective when aligned with the preferences of people directly affected by wildlife, yet little is known about how socioecological factors influence these preferences.

Discovery and Initial Investigation of a New Low Surface Brightness Planetary Nebula Candidate at High Galactic Latitude

Astronomische Nachrichten, Volume 347, Issue 3, March 2026.
ABSTRACT Planetary nebulae represent a late evolutionary phase of low‐ to intermediate‐mass stars. In this article, we present the serendipitous discovery of a previously unknown, faint potential Galactic planetary nebula (PN) in the constellation Camelopardalis, identified during a survey‐inspection, aiming at the detection of dwarf companions of the ...

Large mammalian herbivores disrupt demographic compensation along an aridity gradient

Ecosphere, Volume 17, Issue 3, March 2026.
Abstract Ecologists often assume that demographic rates such as survival and reproduction vary in concert along abiotic gradients, but growing evidence suggests that these rates may change in opposition, leading to demographic compensation. However, it is unclear how biotic interactions such as herbivory may affect the presence or strength of ...

The Neocolonial Tightening of CITES: How Northern Narratives Marginalize Southern Conservation

Conservation Letters, Volume 19, Issue 2, March/April 2026.
ABSTRACT CITES has demonstrated a persistent trend of regulatory tightening over five decades, raising critical questions about both equity and effectiveness in global conservation governance. This study examines how structural power imbalances and dominant Northern narratives within the Convention have systematically marginalized pluralistic ...

Responses of African Savanna Trees to Large Herbivore Extinction and Rewilding

Ecology Letters, Volume 29, Issue 3, March 2026.
Trophic rewilding may be a restoration ‘win‐win’ if the return of extirpated wildlife also restores lost ecosystem function, but few studies have addressed whether wildlife reintroduction is capable of reversing changes that occurred during extirpation.

A Gnawing Question: How Do Caribou and Other Arctic Mammals Exploit Shared Bone Resources?

Ecology and Evolution, Volume 16, Issue 2, February 2026.
Bones of dead animals are consumed by many species, yet the partitioning of this resource, and the associated ecological and evolutionary implications, remains poorly understood. Using bone modification features found on shed female caribou (Rangifer tarandus) antlers and skeletal bones lying on caribou calving grounds of the Arctic National Wildlife ...
