Abstract Global climate change is increasing the frequency and intensity of weather extremes, including severe droughts in many regions. Drought can impact organisms by inhibiting reproduction, reducing survival abundance, forcing range shifts. For birds, considering temporal scale averaging drought‐related variables over different time lengths (i.e., grains) captures hydrologic attributes which may uniquely influence food supplies, vegetation greenness/structure, other factors affecting...
Abstract Understanding the relationship between biodiversity and ecological stability is increasingly urgent as rapid species extinction continues. Though evidence of positive diversity–stability relationships accumulating, empirical results are inconsistent, effect sizes tend to be small, raising questions about relative contributions intrinsic (i.e., composition/interactions) extrinsic environmental) drivers stability. Community may more strongly influenced by environmental conditions than...
Rangelands are extensive ecosystems, providing important ecosystem services while undergoing continuous change. As a result, there is need for improved monitoring technologies that better characterize vegetation changes over space and time. Satellite remote sensing has proven effective in this regard, tracking dynamics at both broad fine scales. Advancements technology provide the opportunity to improve efforts capture subtle yet ecologically significant changes. We leveraged enhanced...
Abstract Invasive species are suspected to be major contributors biodiversity declines worldwide. Counterintuitively, however, invasive effects likely scale dependent and hypothesized positively related at large spatial scales. Past studies investigating the effect of invasion on have been mostly conducted small scales (<100 m 2 ) that cannot represent dynamic landscapes by design. Therefore, replicated experimental evidence supporting a negative plants is lacking across many landscape...
Woody plant encroachment in grasslands represents one of the greatest challenges for global biodiversity conservation. Furthermore, this is a social-ecological problem, where human activity and behavior have resulted significant changes ecological processes that control woody plants, failure to fully recognize role has led continued loss worldwide. It therefore critical conservation professionals understand how systems, settlement patterns, fragmentation from anthropogenic development...
Abstract In this era of global environmental change and rapid regime shifts, managing core areas that species require to survive persist is a grand challenge for conservation. Wildlife monitoring data are often limited or local in scale. The emerging ability map track spatial regimes (i.e., the manifestation state transitions) using advanced geospatial vegetation has potential provide earlier warnings habitat loss because many conservation concern strongly avoid boundaries. Using 23 yr lek...

Abstract Quantifying resource selection (an organism's disproportionate use of available resources) is essential to infer habitat requirements a species, develop management recommendations, predict species responses changing conditions, and improve our understanding the processes that underlie ecological patterns. Because study sites, even within same region, can differ in both amount arrangement cover types, objective was determine whether proximal sites yield markedly different results for...
