The dimensionality of ecological networks
Ecology Letters - Tập 16 Số 5 - Trang 577-583 - 2013
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 find that the
number of dimensions ...
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
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, postulates that the metabolic scaling
exponent (b) varies between 2/3 and 1, and is inversely related to the elevation
of...
Loss of functional diversity under land use intensification across multiple taxa
Ecology Letters - Tập 12 Số 1 - Trang 22-33 - 2009
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 FD responses to
land use intensifi...
Understanding food‐web persistence from local to global scales
Ecology Letters - Tập 13 Số 2 - Trang 154-161 - 2010
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 smaller sub‐webs,
called trophic modules, because these modules are more tractable experimentally
and analytically than whol...
Graph models of habitat mosaics
Ecology Letters - Tập 12 Số 3 - Trang 260-273 - 2009
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 theory. In
these applications, gra...
Low functional redundancy in coastal marine assemblages
Ecology Letters - Tập 8 Số 4 - Trang 391-400 - 2005
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 distinct data sets, one from
kelp fo...
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
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 (18 studies) and
pollination servi...
The risk of marine bioinvasion caused by global shipping
Ecology Letters - Tập 16 Số 6 - Trang 782-790 - 2013
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 ballast water. We find that
invas...
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
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 ra và kiểm nghiệm các dự đoán

Coral reef cascades and the indirect effects of predator removal by exploitation
Ecology Letters - Tập 7 Số 5 - Trang 410-416 - 2004
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 61% and starfish
densities increa...
