Uncertainty is pervasive in ecology where the difficulties of dealing with sources uncertainty are exacerbated by variation system itself. Attempts at classifying have, for most part, focused exclusively on epistemic uncertainty. In this paper we classify into two main categories: (uncertainty determinate facts) and linguistic language). We provide a classification under categories demonstrate how each impacts applications conservation biology. particular, importance recognizing effect...
Species responses to climate change may be influenced by changes in available habitat, as well population processes, species interactions and between demographic landscape dynamics. Current methods for assessing these fail provide an integrated view of influences because they deal with habitat or dynamics, but rarely both. In this study, we linked a time series suitability models spatially explicit stochastic explore factors that influence the viability plant populations under stable...
In conservation biology it is necessary to make management decisions for endangered and threatened species under severe uncertainty. Failure acknowledge treat uncertainty can lead poor decisions. To illustrate the importance of considering uncertainty, we reanalyze a decision problem Sumatran rhino, Dicerorhinus sumatrensis , using information‐gap theory propagate uncertainties rank options. Rather than requiring information about extent parameter at outset, addresses question how much be...
The identification of species at risk extinction is a central goal conservation. As the use data compiled for IUCN Red List assessments expands, number misconceptions regarding purpose, application and categories criteria have arisen. We outline five such classes misconception; most consequential drive proposals adapted versions criteria, rendering among incomparable. A key challenge future will be to recognize point where understanding has developed so markedly that it time next generation...
Ecosystems and the species communities within them are highly complex systems that defy predictions with any degree of certainty. Managing conserving these in face uncertainty remains a daunting challenge, particularly respect to developing networks marine reserves. Here we review several modelling frameworks explicitly acknowledge incorporate uncertainty, then use methods evaluate reserve spacing rules given increasing levels about larval dispersal distances. Our approach finds similar as...
Abstract: Habitat remnants in urbanized areas typically conserve biodiversity and serve the recreation urban open‐space needs of human populations. Nevertheless, these goals can be conflict if activity negatively affects wildlife. Hence, when considering habitat as conservation refuges it is crucial to understand how activities land uses affect wildlife use those adjacent areas. We used tracking data (animal tracks den or bed sites) on 10 animal species information environmental factors...
Degradation of freshwater ecosystems and the services they provide is a primary cause increasing water insecurity, raising need for integrated solutions to management. While methods characterizing multi-faceted challenges managing abound, tend emphasize either social or ecological dimensions fall short being truly integrative. This paper suggests that management sustainability systems needs consider linkages between human uses, governance. We present conceptualization resources as part an...
Abstract Aim Plant distributions and vegetation dynamics underpin key global phenomena, including biogeochemical cycling, ecosystem productivity terrestrial biodiversity patterns. Aggregated remotely collected ‘big data’ are required to forecast the effects of change on plant communities. We synthesize advances in developing exploiting big data ecology, identify challenges their effective use studies. Location Global. Methods explored databases, catalogues registries with respect...

As study model, we examine the impact wind turbines on population dynamics soaring acting conjunction sudden decrease food availability following European bovine spongiform encephalopathy (BSE) epidemic. 2. In Spain, vultures have been provided supplementary at traditional vulture restaurants for centuries. 2006/2007, these...
Abstract Aim To investigate the velocity of species‐specific exposure to climate change for mid‐ and late 21st century develop metrics that quantify over space time. Location California Floristic Province, south‐western USA . Methods Occurrences from presence/absence inventories eight Californian endemic tree species ( P inus balfouriana [Grev.&Balf.], coulteri [D.Don] , muricata [D.Don.], sabiniana [D.Don], Q uercus douglasii [Hook.&Arn.], engelmannii [Greene], lobata [Nee]...
Concern over rapid global changes and the potential for interactions among multiple threats are prompting scientists to combine modelling approaches understand impacts on biodiversity. A relatively recent development is combination of species distribution models, land-use change predictions, dynamic population models predict relative combined climate change, altered disturbance regimes species' extinction risk. Each component introduces its own source uncertainty through different parameters...
Abstract The International Union for Conservation of Nature (IUCN) Red List Categories and Criteria is a quantitative framework classifying species according to extinction risk. Population models may be used estimate risk or population declines. Uncertainty variability arise in threat classifications through measurement process error empirical data uncertainty the Furthermore, traits are known affect We investigated effects error, model type, growth rate, age at first reproduction on...
Abstract Seedling establishment is a critical step that may ultimately govern tree species’ distribution shifts under environmental change. Annual variation in the location of seed rain and microclimates results transient “windows opportunity” for seedling across landscape. These windows vary at fine spatiotemporal scales are not considered most assessments climate change impacts on species range dynamics habitat displacement. We integrate field trials conducted southern Sierra Nevada...
Species distribution and ecological niche models (hereafter SDMs) are popular tools with broad applications in ecology, biodiversity conservation, environmental science. Many SDM require projecting conditions non‐analog to those used for model training (extrapolation), giving predictions that may be statistically unsupported biologically meaningless. We introduce a novel method, Shape, model‐agnostic approach calculates the extrapolation degree given projection data point by its multivariate...
An increasing amount of California's landscape has burned in wildfires recent decades, conjunction with temperatures and vapor pressure deficit due to climate change. As the wildland-urban interface expands, more people are exposed harmed by these extensive wildfires, which also eroding resilience terrestrial ecosystems. With future wildfire activity expected increase, there is an urgent demand for solutions that sustain healthy ecosystems wildfire-resilient human communities. Those who...
This study examines estimates of extinction rates for the current purported biotic crisis and from fossil record. Studies that compare geological extinctions sometimes use metrics confound different sources error reflect features processes. The per taxon rate is a standard measure in paleontology avoids some pitfalls alternative approaches. Extinction reported conservation literature are rarely accompanied by measures uncertainty, despite many elements calculations being subject to...
ABSTRACT Successful conservation plans are not solely achieved by acquiring optimally designed reserves. Ongoing monitoring and management of the biodiversity in those reserves is an equally important, but often neglected or poorly executed, part process. In this paper we address one first most important steps designing a program – deciding what to monitor. We present strategy for prioritizing species multispecies plans. use existing assessments threatened status, degree spatial temporal...
Hybridization in the wild between closely related species is not unusual. In some cases, hybridization may prove beneficial for a rare taxon. Under certain conditions, however, taxon can be driven rapidly to extinction by hybridizing with more common This problem urgent because human activities are increasingly bringing together cross-compatible that were previously geographically isolated. US conservation policy has yet address how deal hybrid-derived individuals whose ancestry includes an...
