Multistage time-to-event models improve survival inference by partitioning mortality processes of tracked organisms Multistage time-to-event models improve survival inference by partitioning mortality processes of tracked organisms
Advances in tagging technologies are expanding opportunities to estimate survival of fish and wildlife populations. Yet, capture and handling effects could impact survival outcomes and bias inference about natural mortality processes. We developed a multistage time-to-event model that can partition the survival process into sequential phases that reflect the tagged animal experience...

Delayed positive responses of snowshoe hares to prescribed burning in a fire-adapted ecosystem Delayed positive responses of snowshoe hares to prescribed burning in a fire-adapted ecosystem
Wildlife populations near the periphery of a species’ range are vulnerable to changes in habitat conditions and climate. However, habitat management and maintenance can help with the persistence of these susceptible populations. Snowshoe hare (Lepus americanus) populations near the southern extent of their range are at risk of extirpation because of changing winter conditions, coupled...

Change-point models for identifying behavioral transitions in wild animals Change-point models for identifying behavioral transitions in wild animals
Animal behavior can be difficult, time-consuming, and costly to observe in the field directly. Innovative modeling methods, such as hidden Markov models (HMMs), allow researchers to infer unobserved animal behaviors from movement data, and implementations often assume that transitions between states occur multiple times. However, some behavioral shifts of interest, such as parturition...

Soil and geomorphic patterns within relict charcoal hearths could represent unique ecosystem niches Soil and geomorphic patterns within relict charcoal hearths could represent unique ecosystem niches
Hearths used for 19th and 20th century charcoal manufacturing have been found to have unique plant communities or to produce unique growth characteristics for some species but not others. Given known differences in hearth morphology, within hearth physical and chemical differences may exist and result in unique ecologic niches. We examined soil stratigraphy across 8 relict charcoal...

Species and physiographic factors drive Indian cucumber root and Canada mayflower plant chemistry: Implications for white-tailed deer forage quality Species and physiographic factors drive Indian cucumber root and Canada mayflower plant chemistry: Implications for white-tailed deer forage quality
Nutrition is fundamental to white-tailed deer (Odocoileus virginianus) management given its relationship to habitat carrying capacity and population productivity. Ecological Sites (ESs) are a United States federal landscape management unit of specific land potential due to unique soils, topography, climate, parent material, and perhaps deer forage nutritional value. We present results of...

Small anthropogenic landforms from past charcoal production control moisture dynamics and chemistry in northcentral Appalachian soils Small anthropogenic landforms from past charcoal production control moisture dynamics and chemistry in northcentral Appalachian soils
Throughout the northeastern United States (U.S.) and Europe, relict charcoal hearths (RCHs) are regularly being discovered in proximity to furnaces once used for the extraction of metal from ore or quick-lime production; charcoal produced in hearths was used as a furnace fuel. Given previous research has shown that topographic and subsurface disturbance can be great when a hearth is...
