Passive acoustic monitoring for the estimation of density of the singing lemur (Indri indri)

Conservation Science and Practice, EarlyView.
Passive acoustic monitoring (PAM) was applied to estimate the density of indri (Indri indri) in the Maromizaha tropical forest by adapting a density‐estimation framework originally developed for marine environments. Using a network of autonomous recorders and GLMMs incorporating directional and environmental covariates, we estimated detection ...

ESO: An evolutionary algorithm for efficient model reduction via automated frequency band selection in passive acoustic monitoring

Methods in Ecology and Evolution, Volume 17, Issue 9, Page 2645-2662, September 2026.
Abstract Passive acoustic monitoring (PAM) is an important tool for wildlife monitoring. Deep learning, particularly convolutional neural networks (CNNs), has become the standard approach for developing bioacoustic classifiers. However, real‐time classification remains challenging due to the high computational complexity of these models and the need ...

Advancing Marine Bioacoustics With Deep Generative Models: A Hybrid Augmentation Strategy for Southern Resident Killer Whale Detection

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Automated detection and classification of marine mammal vocalizations is critical for conservation and management efforts but is hindered by limited annotated datasets and the acoustic complexity of real‐world marine environments. Data augmentation has proven to be an effective strategy to address this limitation by increasing dataset ...

A Conceptual Framework and Methods for Studying the Connectivity of Fishes

Fish and Fisheries, Volume 27, Issue 2, Page 342-369, March 2026.
ABSTRACT Connectivity is a multifaceted concept that has important implications for the management and conservation of marine and freshwater fishes. We developed a conceptual framework that encompasses multiple, interrelated categories of connectedness, including landscape (e.g., structural, functional) connectivity and ecological (e.g., trophic ...

Simulated soundscapes and transfer learning boost the performance of acoustic classifiers under data scarcity

Methods in Ecology and Evolution, Volume 17, Issue 2, Page 322-338, February 2026.
Abstract The biodiversity crisis necessitates spatially extensive methods to monitor multiple taxonomic groups for evidence of change in response to evolving environmental conditions. Programs that combine passive acoustic monitoring and machine learning are increasingly used to meet this need. These methods require large, annotated datasets, which are

Reproductive Phenology and Climatic Drivers of Plant Species Used as Food by the Hainan Gibbon, Nomascus hainanus (Primates: Hylobatidae)

Forests, 2023
The timing of flowering and fruiting plays a critical role in the reproduction, population size, and range of fruit-eating animals. The Hainan Tropical Rainforest National Park, China, hosts one of the world’s most endangered primate species, the Hainan gibbon (Nomascus hainanus). Understanding the phenological patterns of the principal food sources of

How coworker proactive behavior drives employee bootlegging: The roles of goal orientation and self‐construal

Applied Psychology, Volume 75, Issue 1, February 2026.
Abstract Unauthorized, proactive innovative behavior (i.e., bootlegging) is increasingly recognized as an important driver of innovation. Although existing research has predominantly focused on explaining the emergence of bootlegging through formal influences (e.g., leadership and organizational practices), less attention has been paid to the impact of

Y‐Chromosome Genetic Characterization Supports the Establishment of Calving Centered Protected Areas for Tibetan Antelope Conservation

Ecology and Evolution, Volume 15, Issue 8, August 2025.
This study analyzed the genetic diversity, population structure, and historical dynamics of the Y chromosome of the Tibetan antelope (Pantholops hodgsonii), and found that its nucleotide diversity and haplotype diversity were high, and that the population was divided into three genetic populations, but there was no correspondence between the genetic ...

The current status of the Hainan black-crested gibbon Nomascus sp. cf. nasutus hainanus in Bawangling National Nature Reserve, Hainan, China [PDF]

Oryx, 2004
The Hainan black-crested gibbon Nomascus sp. cf. nasutus hainanus is on the verge of extinction. Following studies in the late 1980s and early 1990s only limited observations were made of the remaining population in the Bawangling National Nature Reserve on Hainan Island, China, and the most optimistic estimation of the population size was 23 ...
