Effects of spatial scale of sampling on food web structure
Ecology and Evolution - Tập 5 Số 17 - Trang 3769-3782 - 2015
Spencer A. Wood, Roly Russell, Dieta Hanson, Richard J. Williams, Jennifer A. Dunne
AbstractThis study asks whether the spatial scale of sampling alters structural properties of food webs and whether any differences are attributable to changes in species richness and connectance with scale. Understanding how different aspects of sampling effort affect ecological network structure is important for both fundamental ecological knowledge and the appli...... hiện toàn bộ
Scaling up functional traits for ecosystem services with remote sensing: concepts and methods
Ecology and Evolution - Tập 6 Số 13 - Trang 4359-4371 - 2016
Oscar J. Abelleira Martínez, Alexander K. Fremier, Sven Günter, Zayra Ramos Bendaña, Lee A. Vierling, Sara M. Galbraith, Nilsa A. Bosque‐Pérez, Jenny Ordóñez
AbstractEcosystem service‐based management requires an accurate understanding of how human modification influences ecosystem processes and these relationships are most accurate when based on functional traits. Although trait variation is typically sampled at local scales, remote sensing methods can facilitate scaling up trait variation to regional scales needed for...... hiện toàn bộ
The Urban Heat Island and its spatial scale dependent impact on survival and development in butterflies of different thermal sensitivity
Ecology and Evolution - Tập 6 Số 12 - Trang 4129-4140 - 2016
Aurélien Kaiser, Thomas Merckx, Hans Van Dyck
AbstractClimate alteration is one of the most cited ecological consequences of urbanization. However, the magnitude of this impact is likely to vary with spatial scale. We investigated how this alteration affects the biological fitness of insects, which are especially sensitive to ambient conditions and well‐suited organisms to study urbanization‐related changes in...... hiện toàn bộ
Landscape‐scale accessibility of livestock to tigers: implications of spatial grain for modeling predation risk to mitigate human–carnivore conflict
Ecology and Evolution - Tập 5 Số 6 - Trang 1354-1367 - 2015
Jennifer R. B. Miller, Yadvendradev V. Jhala, Jyotirmay Jena, Oswald J. Schmitz
AbstractInnovative conservation tools are greatly needed to reduce livelihood losses and wildlife declines resulting from human–carnivore conflict. Spatial risk modeling is an emerging method for assessing the spatial patterns of predator–prey interactions, with applications for mitigating carnivore attacks on livestock. Large carnivores that ambush prey attack and...... hiện toàn bộ
Identification of human–carnivore conflict hotspots to prioritize mitigation efforts
Ecology and Evolution - Tập 7 Số 24 - Trang 10630-10639 - 2017
Femke Broekhuis, Samuel A. Cushman, Nicholas B. Elliot
AbstractHuman–carnivore conflict is a primary driver of carnivore declines worldwide and resolving these conflicts is a conservation priority. However, resources to mitigate conflicts are limited and should be focused on areas of highest priority. We conducted 820 semistructured interviews with community members living within Kenya's Maasai Mara ecosystem. A multis...... hiện toàn bộ
Toward accurate molecular identification of species in complex environmental samples: testing the performance of sequence filtering and clustering methods
Ecology and Evolution - Tập 5 Số 11 - Trang 2252-2266 - 2015
Jullien M. Flynn, Emily Brown, Frédéric J. J. Chain, Hugh J. MacIsaac, Melania E. Cristescu
AbstractMetabarcoding has the potential to become a rapid, sensitive, and effective approach for identifying species in complex environmental samples. Accurate molecular identification of species depends on the ability to generate operational taxonomic units (OTUs) that correspond to biological species. ...... hiện toàn bộ
Differential responses of cryptic bat species to the urban landscape
Ecology and Evolution - Tập 6 Số 7 - Trang 2044-2052 - 2016
Paul R. Lintott, Kate E. Barlow, Nils Bunnefeld, Philip Briggs, Clara Gajas Roig, Kirsty J. Park
AbstractUrbanization is a key global driver in the modification of land use and has been linked to population declines even in widespread and relatively common species. Cities comprise a complex assortment of habitat types yet we know relatively little about the effects of their composition and spatial configuration on species distribution. Although many bat specie...... hiện toàn bộ
Ecobat: An online resource to facilitate transparent, evidence‐based interpretation of bat activity data
Ecology and Evolution - Tập 8 Số 2 - Trang 935-941 - 2018
Paul R. Lintott, Sophie Davison, John van Breda, Laura M. Kubasiewicz, David Dowse, Jonathan Daisley, Emily Haddy, Fiona Mathews
AbstractAcoustic surveys of bats are one of the techniques most commonly used by ecological practitioners. The results are used in Ecological Impact Assessments to assess the likely impacts of future developments on species that are widely protected in law, and to monitor developments’ postconstruction. However, there is no standardized methodology for analyzing or...... hiện toàn bộ
Contemporary ocean warming and freshwater conditions are related to later sea age at maturity in Atlantic salmon spawning in Norwegian rivers
Ecology and Evolution - Tập 2 Số 9 - Trang 2192-2203 - 2012
Jaime Otero, Arne J. Jensen, Jan Henning L'Abée‐Lund, Nils Chr. Stenseth, Geir Storvik, Leif Asbjørn Vøllestad
AbstractAtlantic salmon populations are reported to be declining throughout its range, raising major management concerns. Variation in adult fish abundance may be due to variation in survival, growth, and timing of life history decisions. Given the complex life history, utilizing highly divergent habitats, the reasons for declines may be multiple and difficult to d...... hiện toàn bộ
Functional traits, the phylogeny of function, and ecosystem service vulnerability
Ecology and Evolution - Tập 3 Số 9 - Trang 2958-2975 - 2013
Sandra Dı́az, Andy Purvis, Johannes H. C. Cornelissen, Georgina M. Mace, Michael J. Donoghue, Robert M. Ewers, Pedro Jordano, William D. Pearse
AbstractPeople depend on benefits provided by ecological systems. Understanding how these ecosystem services – and the ecosystem properties underpinning them – respond to drivers of change is therefore an urgent priority. We address this challenge through developing a novel risk‐assessment framework that integrates ecological and evolutionary perspectives on functi...... hiện toàn bộ
