The Birds and the Seeds When species are lost from ecosystems through local extinction, pattern of ecological interactions changes. Galetti et al. (p. 1086 ) show how loss large fruit-eating birds tropical forest fragments in Brazil affects reduction seed size a palm species. A data set was compiled that consisted >9000 seeds measured 22 populations over area Atlantic rainforest, including seven areas where large-seed dispersers (toucans, cracids, cotingas) were extinct 15 they still common.
Network approaches to ecological questions have been increasingly used, particularly in recent decades. The abstraction of systems - such as communities through networks interactions between their components indeed provides a way summarize this information with single objects. methodological framework derived from graph theory also numerous and measures analyze these objects can offer new perspectives on established theories well tools address challenges. However, prior using methods test...
Abstract Background Escherichia coli strains are commonly found in the gut microflora of warm-blooded animals. These can be assigned to one four main phylogenetic groups, A, B1, B2 and D, which divided into seven subgroups (A 0 , A 1 2 3 D ), according combination three genetic markers chuA yjaA DNA fragment TspE4.C2. Distinct studies have demonstrated that these phylo-groups differ presence virulence factors, ecological niches life-history. Therefore, aim this work was analyze distribution...
Many ecological systems can be represented as networks of interactions. A key feature in these is their organization into modules, which are subsets tightly connected elements. We introduce MODULAR to perform rapid and autonomous calculation modularity network sets. reads a set files representing unipartite or bipartite networks, identifies modules using two different metrics widely used the literature. To estimate modularity, software offers five optimization methods user. The also includes...
Pleistocene extinctions affected mainly large‐bodied animals, determining the loss or changes in numerous ecological functions. Evidence points to a central role of many extinct megafauna herbivores as seed dispersers. An important step understanding legacy mutualistic interactions is evaluate roles and effectiveness dispersal. Here we use morphological ecophysiological allometries estimate both quantitative qualitative aspects seed‐dispersal services likely provided by megafauna. We...
The dynamics of ecosystem collapse are fundamental to determining how and why biological communities change through time, as well the potential effects extinctions on ecosystems. Here we integrate depictions mammals from Egyptian antiquity with direct lines paleontological archeological evidence infer local community over a 6000-year span. unprecedented temporal resolution this data set enables examination tandem human population growth climate can disrupt mammalian communities. We show that...
Abstract Humans have fragmented, reduced or altered the biodiversity in tropical forests around world. Climate and land‐use change act synergistically, increasing drought fire frequencies, converting several rainforests into derived savannas, a phenomenon known as “savannization.” Yet, we lack full understanding of faunal changes response to transformation plant communities. We argue that composition vertebrate assemblages ecotone regions forest–savanna transitions from South America will be...
1. Much of the current understanding ecological systems is based on theory that does not explicitly take into account individual variation within natural populations. However, individuals may show substantial in resource use. This turn be translated topological properties networks depict interactions among and food resources they consume (individual-resource networks). 2. Different models derived from optimal diet (ODT) predict highly distinct patterns trophic at level should translate...
Interaction intimacy, the degree of biological integration between interacting individuals, shapes ecology and evolution species interactions. A major question in is whether interaction intimacy also way interactions are organized within communities. We combined analyses network structure food web models to test role determining patterns antagonistic interactions, such as host-parasite, predator-prey plant-herbivore Networks describing with low were more connected, nested less modular than...
Climate change will redistribute the global biodiversity in Anthropocene. As climates change, species might move from one place to another, due local extinctions and colonization of new environments. However, existence permeable migratory routes precedes faunal migrations fragmented landscapes. Here, we investigate how dispersal affect outcome climate on distribution Amazon's primate species. We modeled 80 Amazon species, using ecological niche models, projected their potential scenarios...
The end of the Pleistocene was marked by extinction almost all large land mammals worldwide except in Africa. Although debate on extinctions has focused roles climate change and humans, impact perturbations depends properties ecological communities, such as species composition organization interactions. Here, we combined palaeoecological data, food-web models community stability analysis to investigate if differences between modern mammalian assemblages help us understand why megafauna died...
Abstract Aim Global changes will redistribute biodiversity, reshaping ecological interactions and ecosystem processes. The decoupling in the distribution of plants their mutualistic seed dispersers, for instance, may have overlooked eco‐evolutionary effects. How animal‐dispersed respond to dispersers remains largely an open question. Here, we forecast consequences climate change frugivory spatial size evolution a Neotropical palm species. Location Atlantic forests South America. Time period...
Humans have reshaped the distribution of biodiversity across globe, extirpating species from regions otherwise suitable and restricting populations to a subset their original ranges. Here, we ask if anthropogenic range contractions since Late Pleistocene led an under-representation realized niches for megafauna, emblematic group taxa often targeted restoration actions. Using reconstructions past geographic distributions (i.e., natural ranges) 146 extant terrestrial large-bodied (>44 kg)...
The establishment of no-take marine protected areas (MPAs) on coral reefs is a common management strategy for conserving the diversity, abundance, and biomass reef organisms. Generally, well-managed enforced MPAs can increase or maintain diversity function enclosed reef, with some benefits extending to adjacent non-protected reefs. A fundamental question in conservation whether these arise within small (<1 km2), because larval input organisms largely decoupled from local adult reproduction....
Biological networks pervade nature. They describe systems throughout all levels of biological organization, from molecules regulating metabolism to species interactions that shape ecosystem dynamics. The network thinking revealed recurrent organizational patterns in complex systems, such as the formation semi-independent groups connected elements (modularity) and non-random distributions among elements. Other structural patterns, nestedness, have been primarily assessed ecological formed by...
A longstanding debate in evolutionary biology and paleontology is whether ecological interactions such as competition impose diversity dependence on speciation extinction rates. Here, we analyze the fossil record of terrestrial mammalian carnivores North America Eurasia using a Bayesian framework to assess their dynamics were affected by within between families (12 Eurasia, 10 America). We found eight instances within‐clade suppressing rates detected between‐clade effects increasing six...
Abstract Biodiversity loss is a hallmark of our times, but predicting its consequences challenging. Ecological interactions form complex networks with multiple direct and indirect paths through which the impacts an extinction may propagate. Here we show that accounting for these connecting species necessary to predict how extinctions affect integrity ecological networks. Using approach initially developed study information flow, estimate effects in plant–pollinator find even those several...
Abstract The complexity of an ecological community can be distilled into a network, where diverse interactions connect species in web dependencies. Species interact directly with each other and indirectly through environmental effects, however to our knowledge the role these ecosystem engineers has not been considered network models. Here we explore dynamics assembly, colonization extinction depends on constraints imposed by trophic, service, engineering We show that assembly model...
Human activities have altered the abundance and distribution of animals, reshaping ecosystems into novel generally more depauperate configurations. Whereas, overhunting habitat loss threaten numerous species, predation release subsidies from agriculture food waste benefit others. Although these impacts combined can generate multiple different outcomes, we propose that, depending on prevalence anthropogenic drivers, mammalian communities are pushed towards one three main defaunation...
