A low‐cost, long‐running, open‐source stereo camera for tracking aquatic species and their behaviours

open access: yesMethods in Ecology and Evolution, Volume 14, Issue 10, Page 2549-2556, October 2023., 2023
Abstract Ecologists are now widely utilising video data to quantify the behaviours and interactions of animals in the wild. This process can be facilitated by collecting videos in stereo, which can provide information about animals' positions, movements and behaviours in three‐dimensions (3D).

AnimalTA: A highly flexible and easy‐to‐use program for tracking and analysing animal movement in different environments

open access: yesMethods in Ecology and Evolution, Volume 14, Issue 7, Page 1699-1707, July 2023., 2023
Abstract Computer programs for video tracking of animal movement are evolving increasingly efficient, using complex algorithms or artificial intelligence systems. Despite the consequent progress in this field, researchers still face some fundamental problems in the use of such programs. For example, the best‐performing programs are often uneasy to use,

Substantive representation of women, informal quotas and appointed upper house parliaments: The case of the Omani State Council

open access: yesDigest of Middle East Studies, Volume 31, Issue 4, Page 359-379, Fall 2022., 2022
Abstract This paper examines the impact of informal quotas on the substantive representation of women in appointed upper parliaments using the Omani State Council as a case study. Although no formal gender quota has been institutionalized in Oman, it is presumed that the Sultan will assign 17% of the seats to women, effectively an informal quota ...

Introduced dung beetles suppress methane emissions from cattle dung and alter the temporal dynamics of greenhouse gas flux Los escarabajos peloteros introducidos suprimen las emisiones de metano del estiércol de ganado y alteran la dinámica temporal del flujo de gases de efecto invernadero Besouros coprófagos introduzidos suprimem as emissões de metano do esterco bovino e alteram a dinâmica temporal do fluxo de gases de efeito estufa

open access: yesEcological Entomology, EarlyView.
Dung beetles suppressed cumulative methane flux from cattle dung by 85% and reduced total greenhouse gas emissions by 18%. Beetle activity accelerated initial CO2 release but did not alter total cumulative flux. N2O and NH3 fluxes were transient and not consistently driven by beetle presence.

Temporal and Ecological Factors Influencing Aquatic Hyphomycetes in a Tropical Headwater Stream

open access: yesFreshwater Biology, Volume 71, Issue 8, August 2026.
ABSTRACT Aquatic hyphomycetes are key decomposers in headwater streams, yet their temporal dynamics in tropical systems remain poorly understood due to the scarcity of long‐term studies. Here, we investigated the temporal variation of aquatic hyphomycete communities in a tropical Atlantic Forest stream over 5 years, evaluating the relative influence of

Sustained contraceptive‐level plasma concentrations of 4,4′‐dinitrocarbanilide in free‐ranging urban feral pigeons fed a custom bait Niveles plasmáticos altos y sostenidos de 4,4′‐dinitrocarbanilida en palomas domésticas libres alimentadas con un cebo anticonceptivo

open access: yesWildlife Society Bulletin, Volume 49, Issue 4, December 2025.
We assessed the acceptability and consumption of a custom‐developed nicarbazin bait for feral pigeons, inferred its contraceptive efficacy, and evaluated the reversibility of its effects upon cessation of treatment. Only feral pigeons consumed the bait, except for one eared dove that also ingested the food. Continuous administration of this bait raised

Importance of connectivity for carnivore richness and occupancy in fragmented biodiversity hotspots

open access: yesConservation Biology, Volume 39, Issue 6, December 2025.
Abstract Structural connectivity affects wildlife movement between habitat patches, contributing to the persistence of wildlife populations and their resilience to human‐induced and environmental changes. However, its importance to wildlife population persistence remains unclear, particularly in fragmented landscapes, where there are additional co ...
