Differences in Habitat Quality Drive Behavioral Contrasts in Two Family Groups of the Critically Endangered Hainan Gibbon (Nomascus hainanus)

open access: yesIntegrative Zoology, EarlyView.
Habitat quality variation drove distinct behavioral strategies: GC (resource‐rich group) behaviors were influenced by food availability, safety and stability, while GE (resource‐scarce group) behaviors relied more on topography, food, and nutrients. Seasonal behavioral flexibility was demonstrated, with food variables dominating in the dry season and ...

Leaf Area Index (open loop)

open access: yes
<p>Leaf area index (LAI) is unitless measure of the total area of leaves per unit ground area (e.g., an LAI of 1 equates to 1 m2 of leaf area above 1 m2 of ground area), which can be a vital variable for predicting primary production of plants and ...

A Wildlife Multi‐Modal Recognition Method Based on Infrared Camera Images Using MWAC

open access: yesIntegrative Zoology, EarlyView.
A multimodal wild wildlife classification model MWAC consists of two parts:(1) Wavelet KAN module (WDS‐KAN) for image feature extraction, and (2) Label Correlated Text Extraction module (LC‐BERT) for text feature extraction. ABSTRACT Nowadays, infrared camera technology has become an important tool for large‐scale monitoring and assessment of wildlife ...

Leaf Area Index (assimilated data)

open access: yes
<p>Leaf area index (LAI) is unitless measure of the total area of leaves per unit ground area (e.g., an LAI of 1 equates to 1 m2 of leaf area above 1 m2 of ground area), which can be a vital variable for predicting primary production of plants and ...

Cumulative Duration and Habitat Selection Across the Annual‐Cycle Stages: Links to Human Modification in Two Declining Shorebirds

open access: yesIntegrative Zoology, EarlyView.
First multi‐season analysis linking cumulative duration and habitat selection to human modification in two declining shorebirds. A total of 160 cumulative duration was identified at four periods for two species. Longer cumulative duration correlate with higher human modification in coastal wetlands during northward migration and winter.

The PhenoChange network protocol for monitoring leaf phenology in tropical dry ecosystems using phenocameras

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Tropical dry ecosystems (TDEs) cover half of the tropics and play a key role in global carbon dynamics. TDEs present distinct canopy and ground layers that often exhibit contrasting phenological patterns. On‐the‐ground observations of phenology by the human eye, though valuable, may suffer from limited temporal resolution and observer biases ...

Larval character evolution in Holometabola (Insecta)

open access: yesCladistics, EarlyView.
Abstract Larvae, a novel type of immature stage, are a crucial innovation of the Holometabola. Larval features therefore provide key evidence for reconstructing evolutionary transformations in this megadiverse group. Here we present the first formal reconstruction of larval character evolution, using maximum parsimony and Bayesian ancestral‐state ...

Wood Thrush (Hylocichla mustelina) occupancy patterns reveal sensitivity to low precipitation on nonbreeding grounds in northern Costa Rica

open access: yesIbis, EarlyView.
Climatic change and anthropogenic disturbances are reshaping animal populations. Habitat loss and extreme climatic events are particularly strong drivers of declines in species that depend on forested areas. For migratory songbirds, climate and the persistence of suitable habitat over time are fundamental to sustaining populations annually.

Monitoring leaf area index at watershed level through NDVI from Landsat-7/ETM+ data

open access: yesScientia Agricola, 2004
Leaf area index (LAI) is an important parameter of the vegetation canopy, and is used, for instance, to estimate evapotranspiration, an important component of the hydrological cycle. This work analyzed the relationship between LAI, measured in field, and
