This article examines the effects of men’s and women’s participation in micro credit programs on various indicators empowerment using data from a special survey carried out rural Bangladesh. These are well suited to studying how gender‐specific resources alter intrahousehold allocations because they induce differential by gender through requirement that only one adult member per household can participate any program. Empowerment is formalized as an unobserved latent variable reflecting...
Abstract Climate change is anticipated to increase the frequency and intensity of droughts, with major impacts ecosystems globally. Broad-scale assessments vegetation responses drought are needed anticipate, manage, potentially mitigate climate-change effects on ecosystems. We quantified sensitivity in Pacific Northwest, USA, as percent reduction greenness under droughts relative baseline moisture conditions. At a regional scale, shrub-steppe ecosystems—with drier climates lower...
Novel forms of drought are emerging globally, due to climate change, shifting teleconnection patterns, expanding human water use, and a history influence on the environment that increases probability transformational ecological impacts. These costly impacts cascade communities, understanding this changing landscape is one today's grand challenges. By using modified horizon-scanning approach integrated scientists, managers, decision-makers, we identified issues in represent key challenges...
Under climate change, ecosystems are experiencing novel drought regimes, often in combination with stressors that reduce resilience and amplify drought's impacts. Consequently, appears increasingly likely to push systems beyond important physiological ecological thresholds, resulting substantial changes ecosystem characteristics persisting long after ends (i.e., transformation). In the present article, we clarify how can lead transformation across a wide variety of including forests,...
Diagnoses of Shigella flexneri in the United Kingdom (UK) are usually travel-related. However, since 2009, there has been an overall increase UK-acquired cases.

This article explores the development and impact of Māmā Aroha App, a digital health solution designed to support sustain Indigenous breastfeeding practices among Māori communities in New Zealand. women have encountered significant barriers breastfeeding, including loss traditional knowledge, culturally ineffective maternity services, inadequate professional support, compounded by healthcare's limited representation perspectives. Launched on August 2, 2021, App consolidates crucial...
Despite its successes, the U.S. Endangered Species Act (ESA) has proven challenging to implement due funding limitations, workload backlog, and other problems. As threats species survival intensify as more come under threat, need for ESA similar conservation laws policies in countries function efficiently grown. Attempts by Fish Wildlife Service (USFWS) streamline decisions include multispecies recovery plans habitat plans. We address status assessment (SSA), a USFWS process inform from...

Abstract Spring‐fed wetlands are ecologically important habitats in arid and semi‐arid regions. Springs have been suggested as possible hydrologic refugia from droughts climate change; however, springs that depend on recent precipitation or snowmelt for recharge may be vulnerable to warming drought intensification. expected maintain their ecohydrologic function a warmer, drier priorities conservation restoration. Identifying such is difficult because many lack records of adequate temporal...
This paper presents a conceptual framework to operationalize flow–ecology relationships into decision-support systems of practical use water-resource managers, who are commonly tasked with balancing multiple competing socioeconomic and environmental priorities. We illustrate this case study, whereby fish community responses various water-management scenarios were predicted in partially regulated river system at local watershed scale. study simulates management based on interactive effects...
Drivers of soil respiration (R s ) in rock outcrop ecosystems remain poorly understood. We investigated these drivers limestone cedar glades, known for their concentrations endemic plant species and seasonal hydrologic extremes (xeric saturated conditions), compared our findings to those temperate grasslands semi-arid ecosystems. measured R , temperature (T ), volumetric water content (SWC), organic matter (SOM), depth, vegetation cover monthly over 16 mo analyzed effects variables on ....
Abstract Vernal pools of the northeastern United States provide important breeding habitat for amphibians but may be sensitive to droughts and climate change. These seasonal wetlands typically fill by early spring dry mid‐to‐late summer. Because change produce earlier stronger growing‐season evapotranspiration combined with increasing shifts in precipitation timing, management concerns include possibility that some will increasingly become year, potentially interfering amphibian life‐cycle...
Droughts and insect outbreaks are primary disturbance processes linking climate change to tree mortality in western North America. Refugia from these disturbances—locations where impacts less severe relative the surrounding landscape—may be priorities for conservation, restoration, monitoring. In this study, hypotheses concerning physical biological supporting refugia were investigated by modelling landscape controls on that identified using remotely sensed vegetation indicators. at 30-m...
Rock outcrop ecosystems, such as limestone cedar glades (LCGs), are known for their rare and endemic plant species adapted to high levels of abiotic stress. Soils in LCGs thin (< 25 cm), soil-moisture conditions fluctuate seasonally between xeric saturated, summer soil temperatures commonly exceed 48 °C. The effects these stressors on microbial communities (SMC) remain largely unstudied, despite the importance SMC-plant interactions regulating structure function terrestrial ecosystems. SMC...
Regeneration and survival of forested wetlands are affected by environmental variables related to the hydrologic regime. Climate change, specifically alterations precipitation patterns, may have outsized effects on these forests. In Tennessee, USA, has increased 15% since 1960. The goal our research was assess evidence for whether this change in patterns resulted shorter growing seasons recruitment failure common canopy trees a forest wetland. 2001 2018, density Quercus lyrata (overcup oak),...
Water-resource managers are challenged to balance growing water demand with protecting aquatic ecosystems and biodiversity. Management decisions can benefit from improved understanding of water-withdrawal impacts on hydrologic regimes ecological assemblages. This study used limit functions for fish groups within the Tennessee Cumberland River basins predict species richness responses under simulated constant-rate (CR) percent-of-flow (POF) withdrawals different minimum flow level...
Abstract Wetland conservation increasingly must account for climate change and legacies of previous land-use practices. Playa wetlands provide critical wildlife habitat, but may be impacted by intensifying droughts hydrologic modifications. To inform playa restoration planning, we asked: (1) what are the trends in inundation? (2) factors influencing (3) how is inundation affected severe drought? (4) do certain playas refugia during droughts, (5) if so, patterns related to historical...
