Phenology of Racomitrium lanuginosum growing at a seasonally snow-covered site on Mt. Fuji, Japan

Polar Science, 2016
Abstract We investigated the seasonality of the development of the gametangia and sporophytes of Racomitrium lanuginosum growing at a seasonally snow-covered site (ca. 2200 m altitude) on Mt. Fuji, Central Honshu, Japan. Shoots of R. lanuginosum were collected every 2 weeks during the snow-free period (June–November) in 2014.

‘Using anuran community diversity and Pseudacris crucifer to predict landscape quality across a land use gradient'

Wildlife Biology, EarlyView.
As human‐modified landscape and climate changes proliferate, maintaining biodiversity and understanding the function and quality of available habitat is imperative. As anurans (frogs/toads) such as Pseudacris crucifer, can be an indicator species of habitat quality and ecosystem productivity, studying the anuran community in a mixed‐land use region ...

Winter Ecosystem Respiration and Sources of CO2 From the High Arctic Tundra of Svalbard: Response to a Deeper Snow Experiment [PDF]

, 2018
Currently, there is a lack of understanding on how the magnitude and sources of carbon (C) emissions from High Arctic tundra are impacted by changing snow cover duration and depth during winter.

Maximizing the detection probabilities of dusky grouse for population monitoring

Wildlife Biology, EarlyView.
Despite its status as a game species in the western USA, rigorous monitoring of dusky grouse Dendragapus obscurus populations is limited. Obtaining an adequate number of observations for effective population monitoring of dusky grouse is challenging due to difficult‐to‐reach montane habitats, cryptic behaviors, and limited personnel, time, and funds at

Annual survival in a dynamic species: pronghorn survival patterns across their northern range

Wildlife Biology, EarlyView.
Quantifying variation in demographic patterns, such as survival and recruitment, is critical for understanding population dynamics and informing evidence‐based and adaptive wildlife management. In this study, we leverage an extensive dataset from over 1000 GPS collared pronghorn Antilocapra americana to provide the first large‐scale evaluation of ...

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 ...

Effects of snow manipulation on larch trees in the taiga forest ecosystem in northeastern Siberia

Progress in Earth and Planetary Science, 2022
Changes in winter precipitation (snow) may greatly affect vegetation by altering hydrological and biochemical processes. To understand the effects of changing snow cover depth and melt timing on the taiga forest ecosystem, a snow manipulation experiment ...

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.

Combining non‐invasive survey methods increases cumulative detection probability for breeding harlequin ducks Histrionicus histrionicus

Wildlife Biology, EarlyView.
The effective implementation of new technologies for wildlife population monitoring is limited by knowledge of factors that impact their efficacy. Population monitoring of harlequin ducks Histrionicus histrionicus on their breeding streams in Montana and Idaho in the Northern Rocky Mountains, has historically relied on ground‐based foot surveys (GBS ...

How much variation in land surface phenology can climate oscillation modes explain at the scale of mountain pastures in Kyrgyzstan?

International Journal of Applied Earth Observations and Geoinformation, 2020
Climate oscillation modes can shape weather across the globe due to atmospheric teleconnections. We built on the findings of a recent study to assess whether the impacts of teleconnections are detectable and significant in the early season dynamics of ...
