ESPERDYNE: A dual‐band heterodyne monitor and ultrasound recorder for bioacoustic field surveys

Methods in Ecology and Evolution, EarlyView.
Abstract Background. Ultrasonic monitoring is essential for ecological studies of bats and other animals, yet high‐performance field devices remain prohibitively expensive and inaccessible—particularly in biodiversity‐rich regions with limited research infrastructure.

OccuGAMs: Non‐linear occupancy and abundance modelling with imperfect detection

Methods in Ecology and Evolution, EarlyView.
Abstract Hierarchical occupancy and abundance models (HOAMs) have become a leading approach for inferring wildlife population dynamics because they explicitly account for imperfect detection. HOAMs are suitable for sampling approaches that produce detection histories from repeated visits to the same sites, including direct observations (e.g. bird point

A short guide for effective field data collection

Methods in Ecology and Evolution, EarlyView.
Abstract Field data collection is a foundation of ecological research, but it can be challenging and error‐prone. Researchers planning and undertaking fieldwork for the first time are especially vulnerable to logistical issues that can be avoided with more guidance.

Impact of Forest Fragmentation and Associated Edge Effects on Tropical Forest Biodiversity in North West Madagascar, Assessed via Ecoacoustics

Animal Conservation, EarlyView.
Deforestation in the tropics is a major threat to forest‐specialist animals, many of which are already threatened with extinction. We assessed how forest fragmentation and its associated edge‐effects impact animal biodiversity in Northwest Madagascar using soundscape analysis and acoustic indices.

Rethinking Spatial Prioritisation for Primate Conservation in an Unprotected Intact Forest Landscape in the Gulf of Guinea

Animal Conservation, EarlyView.
This study highlights the importance of the unprotected Yabassi Key Biodiversity Area, Cameroon, for primate conservation in the Gulf of Guinea biodiversity hotspot. We modelled primate distribution patterns and found that historically overlooked parts of the landscape have high species richness and are critical for some threatened species.

Habitat use and diel activity of insectivorous bats across land‐cover types on an Afrotropical oceanic island

Conservation Science and Practice, EarlyView.
Using acoustic surveys, we investigated habitat use and diel activity patterns of insectivorous bats across the main land‐use types of the endemic‐rich Príncipe Island, in Central West Africa. We sampled bat activity at 48 sites spanning old‐growth forests, secondary regrowth forests, shaded cocoa plantations, and horticultural areas.

Recompression Improves Release Success in Pollack (Pollachius pollachius): A Step Towards Assessing Post Release Mortality in a Recreational Fishery

Fisheries Management and Ecology, EarlyView.
ABSTRACT The recreational fishery for pollack (Pollachius pollachius) in the northeast Atlantic is impacted by the species' high sensitivity to barotrauma. When captured at depth and brought to the surface, gas expansion within the peritoneal cavity can cause a variety of injuries and hinder release.

Environmental Drivers of Jumbo Squid During Fishery Collapse in the Gulf of California (2019–2024)

Fisheries Oceanography, EarlyView.
ABSTRACT The jumbo squid (Dosidicus gigas) is a cephalopod endemic to the eastern Pacific with significant ecological and economic importance. Its exploitation in the Gulf of California (GC) peaked in the 1990s, with catches exceeding 100,000 tons, but collapsed in 2009 and virtually disappeared by 2015, largely due to environmental changes and ...

Species characteristics predict the effectiveness of avian survey methods in an Afromontane sky‐island

Ibis, EarlyView.
Biodiversity conservation requires effective monitoring of ecological communities in remote locations, where limited accessibility often restricts survey efforts. Passive acoustic monitoring (PAM) is becoming an established method for measuring biodiversity, facilitated by the increased accessibility of autonomous recording units.
