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

Animal Conservation, Volume 29, Issue 3, Page 235-248, June 2026.
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 ...

Australian Mistletoe‐Host Leaf Resemblance: Support for Eco‐Physiological Convergence Rather Than Disperser‐ or Herbivore‐Driven Mimicry

Austral Ecology, Volume 51, Issue 6, June 2026.
ABSTRACT Presently, there are three main hypotheses to explain why the leaves of many Australian mistletoes resemble their hosts. The eco‐physiological convergence hypothesis suggests that mistletoes must manage their physiology, especially their water relations, to match those of the host, to avoid killing themselves or the host branch they have ...

Behavioral Patterns of Zoo‐housed Lowland (Tapirus terrestris) and Malayan tapirs (Tapirus indicus), With a Focus on Sleeping Behavior

Zoo Biology, Volume 45, Issue 3, Page 356-367, May/June 2026.
A behavioral study of the nocturnal activity budget and rhythmicity reveals the relationship between lying cycle (LC) duration and time spent in the REM‐sleep posture (“lying – head down”, LHD) in zoo‐housed Lowland tapirs (Tapirus terrestris) and Malayan tapirs (Tapirus indicus). ABSTRACT To ensure and optimize husbandry conditions, zoo management and

Adaptive data collection strategies for spatial capture–recapture monitoring: Linking monitoring approaches to seasonal variation in density and space use

Ecological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
Effective monitoring of wildlife populations is critical for conservation, but long‐term, large‐scale efforts are often limited, leading to inconsistent and disconnected site‐based data. This study evaluated adaptable, search–encounter data collection strategies for lions (Panthera leo) in Nairobi National Park across three surveys (2018, 2021 and 2022)

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

Zoo Biology, Volume 45, Issue 2, Page 195-202, March/April 2026.
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.

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.
