Unmanned aerial vehicles (UAV) are increasingly used for spatiotemporal monitoring of invasive plants in coastal wetlands. Early identification species is necessary planning, restoring, and managing This study assessed the effectiveness UAV technology to identify Phragmites australis Old Woman Creek (OWC) estuary using machine learning (ML) algorithms: Neural network (NN), support vector (SVM), k-nearest neighbor (kNN). The ML algorithms were compared with parametric maximum likelihood...
Abstract Recognizing the imperative to evaluate species recovery and conservation impact, in 2012 International Union for Conservation of Nature (IUCN) called development a “Green List Species” (now IUCN Green Status Species). A draft framework assessing species’ progress toward recovery, published 2018, proposed 2 separate but interlinked components: standardized method (i.e., measurement against benchmarks viability, functionality, preimpact distribution) determine current status (herein...
Ecological corridors are one of the best, and possibly only viable, management tools to maintain biodiversity at large scales allow species, ecological processes, track climate change. This document has been assembled as a summary best available information about managing these systems. Our aim with this paper is provide managers convenient guidance tool assist in applying scientific principles corridors. We do not cover issues related corridor design or political buy in, but focus on how...

Abstract Intensification of rangeland management has coincided with population declines among obligate grassland species in the largest remaining tallgrass prairie North America, although causes remain unknown. We modeled dynamics and conducted sensitivity analyses from demographic data collected for an bird that is indicator prairie, greater prairie‐chicken ( Tympanuchus cupido ), during a 4‐year study east‐central Kansas, USA. examined components reproductive effort success, juvenile...
Summary The potential effects of wind energy development on wildlife have received increased attention over the past decade. In Kansas, optimal sites for often overlap with preferred habitats greater prairie‐chickens T ympanuchus cupido . Our goal was to determine whether affected survival female in a grassland ecosystem, assessing one impact an upland gamebird conservation concern. We focused primarily response because population dynamics are determined by demography. monitored at facility...
Renewable energy resources have received increased attention because of impacts fossil fuels on global climate change. In Kansas, USA, optimal sites for wind development often overlap with preferred habitats the Greater Prairie-Chicken (Tympanuchus cupido), a lek-mating prairie grouse conservation concern. We tested potential effects male Prairie-Chickens in north-central Kansas. captured males at 23 leks located 0.04 to 28 km from turbines during 2-yr preconstruction period (2007–2008) and...
Abstract Ecological relationships of animals and their environments are known to vary spatially temporally across scales. However, common approaches for evaluating resource selection by assume that the processes habitat stationary space. The assumption is homogeneous may lead biased inference ineffective management. We present first application geographically weighted logistic regression a wildlife species. As case study, we examined nest site greater prairie‐chickens at 3 sites with...
Conservation of wildlife depends on an understanding the interactions between animal movements and key landscape factors. Habitat requirements wide‐ranging species often vary spatially, but quantitative assessment variation among replicated studies at multiple sites is rare. We investigated patterns space use for 10 populations two closely related prairie grouse: Greater Prairie‐Chickens ( Tympanuchus cupido ) Lesser T. pallidicinctus ). Prairie chickens require large, intact tracts native...
Landscape modification due to rapidly expanding energy development, in particular oil and gas, the westernUSA, have prompted concerns over how such developments may impact wildlife. One species of conservation concern across much Intermountain West is greater sage-grouse (Centrocercusurophasianus). Sage-grouse been petitioned for listing under provisions Endangered Species Act 7 times state Wyoming alone represents 64% extant population eastern portion their range. Consequently, relationship...
Many studies have evaluated effectiveness of corridors by measuring species presence in and movement through small structural corridors. However, few assessed whether these response variables are adequate for assessing the conservation goals been achieved or considered costs lag times involved variables. We examined 4 variables-presence focal corridor, interpatch via gene flow, patch occupancy--with respect to 3 criteria--relevance goals, time (fewest generations at which a positive corridor...
Abstract Understanding habitat selection is critical in prioritization for species of conservation and management concern. Information on particularly important grassland bird whose populations have suffered steep declines over the last few decades. We assessed ring‐necked pheasants' ( Phasianus colchicus ) a dynamic agricultural landscape. The population dynamics pheasants are partially related to nest survival, which may be influenced by quality nesting habitat. Consequently, knowledge...
The Cape Horn region of southern Chile is one the remaining bryophyte (mosses, liverworts, and hornworts) hotspots in world. Omora Ethnobotanical Park on Navarino Island contains impressive examples region's diversity. A new trail has been proposed we aimed to predict how a expansion might impact communities. We compared current site found significant differences. Specifically, there was no difference cover diversity, but richness lower at existing trail. These findings indicate that...
Identifying species and subspecies is the foundation for focusing conservation efforts studying evolutionary ecology. Subspecies delineation has occurred using multiple data types, including ecological, morphological, genetic data. There are currently seven recognized Sharp-tailed Grouse (Tympanuchus phasianellus, Linnaeus, 1758) subspecies, with two of these occurring in Wyoming: Columbian (T. p. columbianus) plains jamesi). a third population south-central Wyoming an unknown subspecific...
Conservation corridors are a promising intervention to preserve biodiversity, yet most research has explored in landscape context different from their intended purpose. This Community Page asks readers help identify landscapes that will answer the question: Do work?

The Lesser Prairie-Chicken (Tympanuchus pallidicinctus; LEPC) is an iconic North American prairie grouse, renowned for ornate and spectacular breeding season displays. Unfortunately, the species has disappeared across much of its historical range, with corresponding precipitous declines in contemporary population abundance, largely due to climatic anthropogenic factors. These led a 2022 US Fish Wildlife decision identify list two distinct segments (DPSs; i.e., northern southern DPSs) as...
