Determining the drivers of non-native plant invasions is critical for managing native ecosystems and limiting spread invasive species1,2. Tree in particular have been relatively overlooked, even though they potential to transform economies3,4. Here, leveraging global tree databases5-7, we explore how phylogenetic functional diversity communities, human pressure environment influence establishment species subsequent invasion severity. We find that anthropogenic factors are key predicting...
Safe drinking water access is a human right, but data on safely managed services (SMDWS) lacking for more than half of the global population. We estimate SMDWS use in 135 low- and middle-income countries (LMICs) at subnational levels with geospatial modeling approach, combining existing household survey available datasets. that only one three people used LMICs 2020 identified fecal contamination as primary limiting factor affecting almost population LMICs. Our results are relevant raising...
One mechanism proposed to explain high species diversity in tropical systems is strong negative conspecific density dependence (CDD), which reduces recruitment of juveniles proximity adult plants. Although evidence shows that plant-specific soil pathogens can drive CDD, trees also form key mutualisms with mycorrhizal fungi, may counteract these effects. Across 43 large-scale forest plots worldwide, we tested whether ectomycorrhizal tree exhibit weaker CDD than arbuscular species. We further...
AbstractWhite-tailed deer (Odocoileus virginianus) are managed to yield diverse impacts, including effects ecosystems. Many conventional hunting systems manage abundance through rules that strive produce recreation opportunities and an equitable distribution of antlered bucks among hunters. To protect against excessive harvests, antlerless harvests often regulated quotas. This approach is effective when productivity does not outstrip capacity the hunter population harvest required numbers...
As public participation in environmental decisions has increased, natural resource management agencies have been challenged to involve stakeholders constructively the resolution of a variety contentious issues. This research examines how evaluative criteria, initially derived from theory and literature then refined based on input agency staff stakeholders, can provide with guidance for designing context-specific stakeholder involvement strategies. To illustrations, we conducted inquiries two...
Abstract: Authors have documented a “research-implementation gap” in conservation. Research intended to inform conservation practice often does not, and is not informed by the best science. We used literature on policy learning (i.e., attributing change learning) structure study of how science collaborative studied implementation U.S. states state wildlife action plans. On basis 60 interviews with government nongovernmental organization representatives, we identified 144 initiatives for...
Abstract We conducted a case study of the citizen participation processes used by New York State Department Environmental Conservation (DEC) when deciding whether to reintroduce moose York. studied how citizens perceived fairness and quality process identified criteria on which they based their perceptions. Our work was grounded in research social psychology procedural fairness. Research three phases: document analysis, series interviews, mail survey who commented issue. Citizens'...
Abstract Geospatial modelling can give fundamental insights in the biogeography of life, providing key information about living world current and future climate scenarios. Emerging statistical machine learning approaches help us to generate new levels predictive accuracy exploring spatial patterns ecological biophysical processes. Although these models cannot necessarily represent essential mechanistic that are needed understand global biogeochemical processes under ever-changing...
We propose a way to synthesize different approaches globally map land degradation by combining vegetation and soil indicators into consistent framework for assessing as an environmental 'debt'. our combined approach reveals broader lens through global change, in particular, identifying hot-spots the kinds of degradation.
Protecting the world's remaining forests is a global policy priority. Even though value of in nature, much protection has to come from national policies. Here, we combine global, high resolution remote sensing data on forest outcomes (tree-cover loss, degradation, net primary production) and two complementary econometric research designs for causal inference first quantify how it matters which country located, secondly, role public policies, third, under conditions such pubic policies tend...
Deforestation leads to habitat fragmentation, which adversely affects global biodiversity. Although some studies, using a separation-focused definition, have reported decrease in fragmentation across 75% of the world's forests over recent decades, comprehensive and ecologically relevant understanding patterns remains lacking. In this study, we analyzed trends from 2000 2020, employing metrics that emphasize connectivity, aggregation, or separation. Connectivity-focused reveal 51% forests,...
Because of widespread forest fragmentation, 70% the world’s area lies within 1 km an edge. Forest biomass density near edges often differs markedly from in interior. In some biomes, these “edge effects” are responsible for significant reductions carbon storage. However, there is little consensus on sign and magnitude edge effects across globe, which hampers their consideration stock accounting. Here, we examined eight million forested locations to quantify...
<title>Abstract</title> Environmental restoration projects are crucial for ecosystem recovery and biodiversity conservation but monitoring progress at a global scale poses substantial challenges. Publicly funded satellite missions such as Sentinel-2 have great potential to transform due their high spatial temporal resolution if they can be reliably linked characteristics. Here, we present the first global, analysis-ready, decametric maps three key vegetation biophysical properties on an...
Sea lampreys (Petromyzon marinus) invaded the Great Lakes in early twentieth century and caused considerable economic ecological harm. People who fished suffered crippling losses successfully lobbied elected officials Canada United States to create a sea lamprey control program which Fishery Commission implements under 1954 Convention on Fisheries. The relies two primary methods: chemical lampricides physical barriers. has been tremendous success; although urgency act is apparent certain...
Ongoing fragmentation puts increasing parts of the world&#8217;s forests in proximity to edges. Forest edges are known differ from interiors for many ecosystem variables like biomass and species diversity, but also microclimate. While it is documented that temperatures change with presence absence forests, our knowledge edge effects (temperature distance forest edge) largely restricted local studies shorter timeframes. Here, we use satellite data investigate surface temperature across...
Certain species of wildlife cause considerable damage and therefore receive management attention. Traditional methods rely on lethal control, but fertility control is increasingly being advocated as a more humane alternative. Because decisions are influenced by citizen input, it important to understand what makes people support or oppose control. We studied six U.S. communities trying manage large populations white-tailed deer feral cats categorized the ethical arguments citizens used their...
Introduction To sustain black bear (Ursus americanus) populations, wildlife managers should understand the coupled socio-ecological systems that influence acceptance capacity for bears. Method In a study area encompassing portion of New York State, we spatially matched datasets from three sources: human-bear conflict reports between 2006 and 2018, estimates local density in 2017–2018, responses to 2018 property owner survey (n=1,772). We used structural equation modeling test hypothesized...
We evaluated the conceptual basis of a citizen participation program that was part process used to decide whether or not reintroduce moose northern New York. criticisms liberal political theory illustrate potential weaknesses basing policy decisions mainly on citizens' preferences. The York State Department Environmental Conservation (DEC) determined it would make its decision about citizens ' This strongly influenced how DEC designed strategies. strategies were appropriate for measuring...
Abstract We compared how men and women made decisions about what options were most appropriate for managing an overabundant deer herd in Irondequoit, NY. Data collected through a set of in-depth, semistructured interviews mail survey. Women evaluated management alternatives differently; considered more criteria than concerned the ancillary impacts techniques?the those techniques would have on aspects their community other deer-related problems. Results are consistent with theories gender...
