Phenological drivers of ungulate migration in South America: characterizing the movement and seasonal habitat use of guanacos

Movement Ecology, 2022
Background Migration is a widespread strategy among ungulates to cope with seasonality. Phenology, especially in seasonally snow-covered landscapes featuring “white waves” of snow accumulation and “green waves” of plant green-up, is a phenomenon that ...

Quantifying microhabitat selection of snowshoe hares using forest metrics from UAS‐based LiDAR

Wildlife Biology, EarlyView.
Identifying the spatial and temporal scale at which animals select resources is critical for predicting how populations respond to changes in the environment. The spatial distribution of fine‐scale resources (e.g. patches of dense vegetation) are often linked with critical life‐history requirements such as denning and feeding sites.

Modernizing environmental data management for ecological research, management, and conservation at regional scales

Wildlife Society Bulletin, EarlyView.
We developed a web GIS system that delivers geospatial data for Wyoming and the Greater Yellowstone Ecosystem (GYE) using cloud‐optimized formats and open‐source tools to support regional ecological research and management. Using pronghorn as an example, we combined observed locations with environmental covariates from our geospatial library to map ...

Winter and spring climatic conditions influence timing and synchrony of calving in reindeer.

PLoS ONE, 2018
In a context of climate change, a mismatch has been shown to occur between some species' reproductive phenology and their environment. So far, few studies have either documented temporal trends in calving phenology or assessed which climatic variables ...

Snow Cover Phenology Monitoring and Dynamic Analysis Using Google Earth Engine in Western Iran’s Mountainous Regions [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Snow cover in mountainous regions plays a vital role in regional climate regulation, freshwater supply, and ecosystem stability. Phenological variations in snow cover—ranging from shifts in onset and melting periods to fluctuations in snow extent ...

Integrating large mammalian herbivores into Dynamic Global Vegetation Models: Status and next steps

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Zoogeochemistry, the study of how animals influence elemental cycling within ecosystems, bridges the fields of zoology, ecology and biogeochemistry. Yet, most terrestrial ecosystem models, especially Dynamic Global Vegetation Models (DGVMs), remain largely plant‐centric

Reply to Wang et al.: Snow cover and air temperature affect the rate of changes in spring phenology in the Tibetan Plateau [PDF]

Proceedings of the National Academy of Sciences, 2013
We appreciate the comments on our recent study (1) from Wang et al. (2). Our study showed that the start of the growing season (SOS), derived from analysis of Normalized Difference Vegetation Index (NDVI), continued to advance in the Tibetan Plateau (TP) from 1982 to 2011. Wang et al.

From steps to home ranges: How habitat disturbance influences the movement drivers of an arboreal primate

Journal of Animal Ecology, EarlyView.
Challenging the narrative about howler monkeys' high resilience to anthropogenic changes, our multiscale analysis reveals the costs of habitat disturbance to their movement ecology. We identify thermal limitations, reduced travel efficiency, and significant spatial saturation.

The new indices to describe temporal discontinuity of snow cover on the Qinghai-Tibet Plateau

npj Climate and Atmospheric Science
Snow cover on the Qinghai-Tibet Plateau significantly impacts the climate, hydrology, and ecology of China and East Asia. Current studies mainly use snow cover days to describe its duration, overlooking the snow’s discontinuous nature.
