The dimensionality of ecological networks
Ecology Letters - Tập 16 Số 5 - Trang 577-583 - 2013
Anna Eklöf, Ute Jacob, Jason C. Kopp, Jordi Bosch, Rocío Castro‐Urgal, Natacha P. Chacoff, Bo Dalsgaard, Claudio de Sassi, Mauro Galetti, Paulo R. Guimarães, Silvia B. Lomáscolo, Ana M. Martín González, Marco A. Pizo, Romina Rader, Anselm Rodrigo, Jason M. Tylianakis, Diego P. Vázquez, Stefano Allesina
AbstractHow many dimensions (trait‐axes) are required to predict whether two species interact? This unanswered question originated with the idea of ecological niches, and yet bears relevance today for understanding what determines network structure. Here, we analyse a set of 200 ecological networks, including food webs, antagonistic and mutualistic networks, and fi...... hiện toàn bộ
The intraspecific scaling of metabolic rate with body mass in fishes depends on lifestyle and temperature
Ecology Letters - Tập 13 Số 2 - Trang 184-193 - 2010
Shaun S. Killen, David Atkinson, Douglas S. Glazier
Ecology Letters (2010) 13: 184–193AbstractMetabolic energy fuels all biological processes, and therefore theories that explain the scaling of metabolic rate with body mass potentially have great predictive power in ecology. A new model, that could improve this predictive power...... hiện toàn bộ
Loss of functional diversity under land use intensification across multiple taxa
Ecology Letters - Tập 12 Số 1 - Trang 22-33 - 2009
Dan F. B. Flynn, Melanie Gogol‐Prokurat, Theresa M. Nogeire, Nicole A. Molinari, Bárbara Trautman Richers, Brenda B. Lin, Nicholas T. Simpson, Margaret M. Mayfield, Fabrice DeClerck
AbstractLand use intensification can greatly reduce species richness and ecosystem functioning. However, species richness determines ecosystem functioning through the diversity and values of traits of species present. Here, we analyze changes in species richness and functional diversity (FD) at varying agricultural land use intensity levels. We test hypotheses of F...... hiện toàn bộ
Understanding food‐web persistence from local to global scales
Ecology Letters - Tập 13 Số 2 - Trang 154-161 - 2010
Daniel B. Stouffer, Jordi Bascompte
Ecology letters(2010) 13: 154–161AbstractUnderstanding food‐web persistence is an important long‐term objective of ecology because of its relevance in maintaining biodiversity. To date, many dynamic studies of food‐web behaviour—both empirical and theoretical—have focused on sm...... hiện toàn bộ
Graph models of habitat mosaics
Ecology Letters - Tập 12 Số 3 - Trang 260-273 - 2009
Dean L. Urban, Emily S. Minor, Eric A. Treml, Robert S. Schick
AbstractGraph theory is a body of mathematics dealing with problems of connectivity, flow, and routing in networks ranging from social groups to computer networks. Recently, network applications have erupted in many fields, and graph models are now being applied in landscape ecology and conservation biology, particularly for applications couched in metapopulation t...... hiện toàn bộ
Low functional redundancy in coastal marine assemblages
Ecology Letters - Tập 8 Số 4 - Trang 391-400 - 2005
Fiorenza Micheli, Benjamin S. Halpern
AbstractThe relationship between species and functional diversity remains poorly understood for nearly all ecosystem types, yet determining this relationship is critically important for developing both a mechanistic understanding of community assembly and appropriate expectations and approaches to protecting and restoring biological communities. Here we use two dis...... hiện toàn bộ
The effectiveness of flower strips and hedgerows on pest control, pollination services and crop yield: a quantitative synthesis
Ecology Letters - Tập 23 Số 10 - Trang 1488-1498 - 2020

Entling, Dominik Ganser, G.A. de Groot, Dave Goulson, Heather Grab, Hannah Hamilton, Félix Herzog, Rufus Isaacs, Katja Jacot, Philippe Jeanneret, Mattias Jonsson, Eva Knop, Claire Kremen, Douglas A.

Sciligo, Carsten Thies, Teja Tscharntke, Eric Venturini, Eve Veromann, Ines M.G. Vollhardt, Felix Wäckers, Catrin Westphal, Andrew Wilby, Megan Woltz, Louis Sutter
AbstractFloral plantings are promoted to foster ecological intensification of agriculture through provisioning of ecosystem services. However, a comprehensive assessment of the effectiveness of different floral plantings, their characteristics and consequences for crop yield is lacking. Here we quantified the impacts of flower strips and hedgerows on pest control (...... hiện toàn bộ
The risk of marine bioinvasion caused by global shipping
Ecology Letters - Tập 16 Số 6 - Trang 782-790 - 2013
Hanno Seebens, Michael T. Gastner, Bernd Blasius
AbstractThe rate of biological invasions has strongly increased during the last decades, mostly due to the accelerated spread of species by increasing global trade and transport. Here, we combine the network of global cargo ship movements with port environmental conditions and biogeography to quantify the probability of new primary invasions through the release of ...... hiện toàn bộ
Dự đoán và thử nghiệm các giả thuyết dựa trên khí hậu về sự biến đổi quy mô lớn trong sự phong phú thuế tộc Dịch bởi AI
Ecology Letters - Tập 7 Số 12 - Trang 1121-1134 - 2004
David J. Currie, Gary G. Mittelbach, Howard V. Cornell, Richard Field, Jean‐François Guégan, Bradford A. Hawkins, Dawn M. Kaufman, Jeremy T. Kerr, Thierry Oberdorff, Eileen M. O’Brien, John R. G. Turner
Tóm tắtSự biến đổi quy mô lớn trong độ phong phú về thuế tộc có mối tương quan mạnh mẽ với khí hậu. Nhiều cơ chế đã được giả thuyết để giải thích những mô hình này; tuy nhiên, các dự đoán có thể kiểm chứng để phân biệt giữa chúng hiếm khi được đưa ra. Tại đây, chúng tôi xem xét một số giả thuyết nổi bật về mối quan hệ giữa khí hậu và độ phong phú, trước tiên là đưa...... hiện toàn bộ
Coral reef cascades and the indirect effects of predator removal by exploitation
Ecology Letters - Tập 7 Số 5 - Trang 410-416 - 2004
Nicholas K. Dulvy, Robert P. Freckleton, Nicholas Polunin
AbstractFisheries exploitation provides the opportunity to examine the ecosystem‐scale biodiversity consequences of predator removal. We document predatory reef fish densities, coral‐eating starfish densities and coral reef structure along a 13‐island gradient of subsistence exploitation in Fiji. Along the fishing intensity gradient, predator densities declined by ...... hiện toàn bộ
