Avian species richness and abundance shows stronger response to bison grazing intensity than to ecosystem productivity
Temperate grassland ecosystems are one of the most threatened ecosystems worldwide, and their loss endangers the grassland songbirds that rely upon them. This guild of birds has shown long-term declines in North America. At the same time, American bison (Bison bison) are becoming more common through reintroductions, and they may make significant modifications to grassland songbird habitat. To support conservation for this guild, we sought to understand the importance of bison grazing and ecosystem productivity to the species richness, occupancy, and abundance of this avian community. We conducted dependent double-observer bird counts, measured bison grazing intensity with patty counts, and used remote-sensed Normalized Difference Vegetation Index (NDVI) data to measure ecosystem productivity. Our work took place in the National Bison Range near Moiese, Montana and in Yellowstone National Park in Wyoming. We found that species richness was positively correlated with patty counts, and had a weak negative correlation with NDVI. Occupancy probability for six of seven grassland songbird species was positively correlated with patty counts, and for six of seven species was negatively correlated with NDVI. Abundance of vesper sparrow (Pooecetes graminueus) and western meadowlark (Sturnella neglecta) were positively correlated with patty counts, although for western meadowlark, this trend became less positive with increasing patty counts. Our work suggests that managers may want to encourage a broad range of bison grazing intensities to ensure that vegetative conditions related to bison grazing are present for all species.
Niche overlap between two large herbivores across landscape variability using dietary eDNA metabarcoding: Raw sequences of European bison and red deer – Bialowieza
<p><span>Understanding the trophic ecology of herbivore species is key to assess their environmental requirements and to improve management policies, but measuring their trophic interactions remains challenging. Among the methods available, quantifying the plant composition of a species' diet provides a detailed picture of how species exploit the resources in their environment and their associated niche overlap. Yet, most studies focusing on herbivore trophic ecology ignore the influence that landscape variability may have. Here, we studied how landscape variability influences trophic interactions through niche partitioning. We used eDNA metabarcoding to quantify the diet composition of two large herbivores of the Bialowieza Forest, red deer (<em>Cervus elaphus</em>) and European bison (<em>Bison bonasus</em>, hereafter referred to as bison) to investigate how increasing habitat quality and predation risk in their environment influence their diet composition and niche partitioning. We found red deer to have an overall greater diet variability and lower niche overlap within species compared to bison. Moreover, our findings indicate herbivore interactions are non-homogeneous across the landscape. Higher habitat quality was associated with higher niche overlap only within bison. We also detected an increase in niche overlap with increasing predation risk within red deer, indicating they modify their diet choice as a reaction to wolf predation risk. This study provides evidence of eDNA dietary metabarcoding as a useful tool for wildlife management to assess the status of species in an ecosystem based on known environmental factors. We suggest future studies to integrate the environments' variability when studying trophic ecology of herbivores to capture the whole extent of species interaction in order to improve conservation and management guidelines. </span></p>

Bison movement response to weather
<p><span>Animal movement patterns are affected by complex interactions between biotic and abiotic landscape conditions, and these patterns are being altered by weather variability associated with a changing climate. Some animals, like the American plains bison (</span><span><em>Bison</em> <em>bison</em></span><span> L.; hereafter, plains bison), are considered keystone species, thus their response to weather variability may alter ecosystem structure and biodiversity patterns. Many movement studies of plains bison and other ungulates have focused on point‐pattern analyses (e.g., resource‐selection) that have provided information about where these animals move, but information about when or why these animals move is limited. For example, information surrounding the influence of weather on plains bison movement in response to weather is limited but has important implications for their conservation in a changing climate. To explore how movement distance is affected by weather patterns and drought, we utilized 12‐min GPS data from two of the largest plains bison herds in North America to model their response to weather and drought parameters using generalized additive mixed models. Distance moved was best predicted by air temperature, wind speed, and rainfall. However, air temperature best explained the variation in distance moved compared to any other single parameter we measured, predicting a 48% decrease in movement rates above 28°C. Moreover, severe drought (as indicated by 25‐cm depth soil moisture) better predicted movement distance than moderate drought. The strong influence of weather and drought on plains bison movements observed in our study suggests that shifting climate and weather patterns will likely affect plains bison movement patterns, further complicating conservation efforts for this wide‐ranging keystone species. Moreover, changes in plains bison movement patterns may have cascading effects for grassland ecosystem structure, function, and biodiversity. Plains bison and grassland conservation efforts need to be proactive and adaptive when considering the implications of a changing climate on bison movement patterns.</span></p>
