Selecting thresholds of occurrence in the prediction of species distributions
Ecography - Tập 28 Số 3 - Trang 385-393 - 2005
Canran Liu, Pam Berry, Terence P. Dawson, Richard G. Pearson
Transforming the results of species distribution modelling from probabilities of or suitabilities for species occurrence to presences/absences needs a specific threshold. Even though there are many approaches to determining thresholds, there is no comparative study. In this paper, twelve approaches were compared using two species in Europe and artificial neural networks, and the modelling ...... hiện toàn bộ
Flexibility, efficiency, and accountability: adapting reserve selection algorithms to more complex conservation problems
Ecography - Tập 23 Số 5 - Trang 565-574 - 2000
Ana S. L. Rodrigues, Jorge Orestes Cerdeira, Kevin J. Gaston
Exposure of mammal genetic diversity to mid‐21st century global change
Ecography - Tập 44 Số 6 - Trang 817-831 - 2021
Spyros Theodoridis, Carsten Rahbek, David Nogués‐Bravo
Accelerating climate and land‐use change are rapidly transforming Earth's biodiversity. While there is substantial evidence on the exposure and vulnerability of biodiversity to global change at the species level, the global exposure of intraspecific genetic diversity (GD) is still unknown. Here, we assess the exposure of mitochondrial GD to mid‐21st century climate and land‐use change in t...... hiện toàn bộ
Climate and geographic distance are more influential than rivers on the beta diversity of passerine birds in Amazonia
Ecography - Tập 43 Số 6 - Trang 860-868 - 2020
Isadora E. Fluck, Nilton C. Cáceres, Carla Deonísia Hendges, Mariana N. Brum, Cristian Dambros
Variation in the spatial structure of communities in terms of species composition (beta diversity) is affected by different ecological processes, such as environmental filtering and dispersal limitation. Large rivers are known as barriers for species dispersal (riverine hypothesis) in tropical regions. However, when organisms are not dispersal limited by geographic barriers, other factors,...... hiện toàn bộ
Ontogenetic changes in the micro‐habitat preferences of Decticus verrucivorus (Orthoptera: Tettigoniidae) at the edge of its range
Ecography - Tập 15 Số 1 - Trang 37-44 - 1992
Andrew Cherrill, V. K. Brown
The large ground‐dwelling bush cricket Decucus verrucivorus is widespread in continental Europe, but declining at the northern edge of its range This paper defines the species' habitat requirements in northern Europe by describing the distribution of each of the seven nymphal instars and adults in relation to vegetation structure within a chalk grassland in south...... hiện toàn bộ
Phylogenetic community structure and phylogenetic turnover across space and edaphic gradients in western Amazonian tree communities
Ecography - Tập 34 Số 4 - Trang 552-565 - 2011
Paul V. A. Fine, Steven W. Kembel
Comprehensive estimation of spatial and temporal migratory connectivity across the annual cycle to direct conservation efforts
Ecography - Tập 44 Số 5 - Trang 665-679 - 2021
Elly C. Knight, Autumn‐Lynn Harrison, Amy L. Scarpignato, Steven L. Van Wilgenburg, Erin M. Bayne, Janet W. Ng, Emily Angell, Reed Bowman, R. Mark Brigham, Bruno Drolet, Wendy E. Easton, Timothy R. Forrester, Jeffrey T. Foster, Samuel Haché, Kevin C. Hannah, Kristina Hick, Jacques Ibarzabal, Tara L. Imlay, Stuart A. Mackenzie, A.C. Marsh, Liam P. McGuire, Gretchen N. Newberry, David J. Newstead, Andrea Sidler, Pam H. Sinclair, Jaime L. Stephens, David L. Swanson, Junior A. Tremblay, Peter P. Marra
Migratory connectivity is the degree to which populations are linked in space and time across the annual cycle. Low connectivity indicates mixing of populations while high connectivity indicates population separation in space or time. High migratory connectivity makes individual populations susceptible to local environmental conditions; therefore, evaluating migratory connectivity continuo...... hiện toàn bộ
Where do animals come from during post‐fire population recovery? Implications for ecological and genetic patterns in post‐fire landscapes
Ecography - Tập 40 Số 11 - Trang 1325-1338 - 2017
Sam C. Banks, Lachlan McBurney, David Blair, Ian D. Davies, David B. Lindenmayer
Identifying where animals come from during population recovery can help to understand the impacts of disturbance events and regimes on species distributions and genetic diversity. Alternative recovery processes for animal populations affected by fire include external recolonization, nucleated recovery from refuges, or in situ survival and population growth. We used simulations to develop h...... hiện toàn bộ
Do stream fish track climate change? Assessing distribution shifts in recent decades
Ecography - Tập 36 Số 11 - Trang 1236-1246 - 2013
Lise Comte, Gaël Grenouillet
Understanding the ability of species to shift their distribution ranges in response to climate change is crucial for conservation biologists and resources managers. Although freshwater ecosystems include some of the most imperilled fauna worldwide, such range shifts have been poorly documented in streams and rivers and have never been compared to the current velocity of climate change.

Awesome or ordinary? Global diversity patterns of oribatid mites
Ecography - Tập 30 Số 2 - Trang 209-216 - 2007
Mark Maraun, Heinrich Schatz, Stefan Scheu
Diversity of most above‐ground organisms increases with decreasing latitude, but the biogeographical and macroecological diversity patterns of below‐ground animals have been poorly studied. We investigated the latitudinal diversity gradient in a primarily below‐ground living soil taxon, oribatid mites. Furthermore, oribatid mite species richness from islands and mainlainds was tested for c...... hiện toàn bộ
