Data from: Realized trophic niche driven by apparent competition: an example with marsupials

Vanessa V. Kuhnen, Marcus A. Martinez De Aguiar, Ana Zangirolame Gonçalves & Eleonore Zulnara Freire Setz.
According to apparent competition theory, the co-occurrence of two species that share the same predators appears to affect each other's population growth and abundance. However, due to habitat loss and over-hunting, top predators are being made rare worldwide. Considering that apparent competitors share similar resources, we would expect the absence of top predators to reflect in changes on prey realized trophic niches. To test our hypothesis, we developed a model to predict the abundance ratio...

Data from: Abandoned pastures cannot spontaneously recover the attributes of old-growth savannas

Mario G. B. Cava, Natashi A. L. Pilon, Milton Cezar Ribeiro & Giselda Durigan
1.Active restoration strategies have been recommended to recover Neotropical savannas in abandoned lands, but no studies have investigated the trajectories and speeds of spontaneous recovery for these systems. Research into the dynamics of degraded savannas is urgently needed to guide restoration decision-making. 2.We analysed the dynamics of secondary savannas in the Brazilian Cerrado by sampling 29 abandoned pastures (time since abandonment ranging from 3 to 25 years) and applying the space-for-time substitution method. We modelled...

Data from: Effects of predatory ants within and across ecosystems in bromeliad food webs

Ana Z. Gonçalves, Diane S. Srivastava, Paulo S. Oliveira & Gustavo Q. Romero
Predation is one of the most fundamental ecological processes affecting biotic communities. Terrestrial predators that live at ecosystem boundaries may alter the diversity of terrestrial organisms, but they may also have cross-ecosystem cascading effects when they feed on organisms with complex life cycles (i.e. organisms that shift from aquatic juvenile stages to terrestrial adult stages) or inhibit female oviposition in the aquatic environment. The predatory ant Odontomachus hastatus establishes its colonies among roots of Vriesea...

, Anne Bruneau, Nasim Azani, Marielle Babineau, Edeline Gagnon, Carole Sinou, Royce Steeves, Erin Zimmerman, C. Donovan Bailey, Lynsey Kovar, Madhugiri Nageswara-Rao, Hannah Banks, RuthP. Clark, Manuel De La Estrella, Peter Gasson, GeoffreyC. Kite, BenteB. Klitgaard, GwilymP. Lewis, Danilo Neves, Gerhard Prenner, María De Lourdes Rico-Arce, ArianeR. Barbosa, Maria Cristina López-Roberts, Luciano Paganucci De Queiroz, PétalaG. Ribeiro … & Tingshuang Yi
The classification of the legume family proposed here addresses the long-known non-monophyly of the traditionally recognised subfamily Caesalpinioideae, by recognising six robustly supported monophyletic subfamilies. This new classification uses as its framework the most comprehensive phylogenetic analyses of legumes to date, based on plastid matK gene sequences, and including near-complete sampling of genera (698 of the currently recognised 765 genera) and ca. 20% (3696) of known species. The matK gene region has been the most...

This data set aims to provide data from Go Amazon project in order to study the diurnal cycle of atmospheric properties on site T2.

Data from: Geographical and intrapopulation variation in the diet of a threatened marine predator, Pontoporia blainvillei (Cetacea)

Barbara Henning, Benilton De Sá Carvalho, Mathias Mistretta Pires, Manuela Bassoi, Juliana Marigo, Carolina Bertozzi & Márcio S. Araújo.
Diet variation can occur in geographically structured populations due to variation in prey availability. Within locations, diet may vary due to effects of season, sex, age, and individual. Nevertheless, these sources of variation are seldom considered together in dietary studies. Major efforts are underway to investigate population and ecological traits of marine organisms to set guidelines for conservation and management. Examining diet variation is a major concern when developing conservation guidelines for threatened species, especially...

Data from: The role of the endemic and critically endangered Colorful Puffleg Eriocnemis mirabilis in plant-hummingbird networks of the Colombian Andes

Mónica B. Ramírez-Burbano, F. Gary Stiles, Catalina González, Felipe W. Amorim, Bo Dalsgaard, Pietro K. Maruyama. & Pietro K. Maruyama
Ecological network approaches may contribute to conservation practices by quantifying within-community importance of species. In mutualistic plant-pollinator systems, such networks reflect potential pollination of the plants and a considerable portion of the energy consumption by the pollinators, two key components for each party. Here, we used two different sampling approaches to describe mutualistic plant-hummingbird networks from a cloud forest in the Colombian Western Andes, home to the Colorful Puffleg Eriocnemis mirabilis, an endemic and critically...

Data from: Mating system and effective population size of the overexploited Neotropical tree (Myroxylon peruiferum L.f.) and their impact on seedling production

Ellida De Aguiar Silvestre, Kaiser Dias Schwarcz, Carolina Grando, Jaqueline Bueno De Campos, Patricia Sanae Sujii, Evandro Vagner Tambarussi, Camila Menezes Trindade Macrini, José Baldin Pinheiro, Pedro Henrique Santin Brancalion & Maria Imaculada Zucchi
The reproductive system of a tree species has substantial impact on genetic diversity and structure within and among natural populations. Such information, should be considered when planning tree planting for forest restoration. Here, we describe the mating system and genetic diversity of an overexploited Neotropical tree, Myroxylon peruiferum L.f. (Fabaceae) sampled from a forest remnant (10 seed trees and 200 seeds) and assess whether the effective population size of nursery-grown seedlings (148 seedlings) is sufficient...

Data from: Evolutionary history as a driver of ecological networks: a case study of plant-hummingbird interactions

Rômulo S. Vitória, Jeferson Vizentin-Bugoni & Leandro D.S. Duarte
Multiple factors drive species interactions in ecological networks, such as morphological barriers, spatio-temporal distribution, abundances and evolutionary histories of species. Novel methods are making it possible to evaluate the relative importance of each of these drivers. However, the lack of appropriate methods has prevented evaluating the extent to which interaction networks are shaped by species’ evolutionary histories. This study includes the evolutionary histories of species among the potential drivers of interactions, allowing the comparative analysis...

Data from: Influence of historical land use and modern agricultural expansion on the spatial and ecological divergence of sugarcane borer, Diatraea saccharalis (Lepidoptera: Crambidae) in Brazil

Vitor A.C. Pavinato, Andrew P. Michel, Jaqueline B. De Campos, Celso Omoto & Maria I. Zucchi
Human-mediated changes in landscapes can facilitate niche expansion and accelerate the adaptation of insect species. The interaction between the evolutionary history of the sugarcane borer, Diatraea saccharalis Fabricius, and historical and modern agricultural activity in Brazil shaped its spatial genetic structure, facilitating ecological divergence and incipient host-shifting. Based on microsatellite data, STRUCTURE analyses identified two (K=2) and three (K=3) significant genetic clusters that corresponded to: a) a strong signal of spatial genetic structure and, b)...

Data from: Warming and top predator loss drive ecosystem multifunctionality

Pablo Augusto P. Antiqueira, Owen L. Petchey & Gustavo Quevedo Romero
Global change affects ecosystem functioning both directly by modifications in physicochemical processes, and indirectly, via changes in biotic metabolism and interactions. Unclear, however, is how multiple anthropogenic drivers affect different components of community structure and the performance of multiple ecosystem functions (ecosystem multifunctionality). We manipulated small natural freshwater ecosystems to investigate how warming and top predator loss affect seven ecosystem functions representing two major dimensions of ecosystem functioning, productivity and metabolism. We investigated their direct...

Data from: Gypsy moth herbivory induced volatiles and reduced parasite attachment to cranberry hosts

Muvari C. Tjiurutue, Hilary A. Sandler, Monica F. Kersch-Becker, Nina Theis & Lynn S. Adler
Interactions between species can have cascading effects that shape subsequent interactions. For example, herbivory can induce plant defenses that affect subsequent interactions with herbivores, pathogens, mycorrhizae, and pollinators. Parasitic plants are present in most ecosystems, and play important roles in structuring communities. However, the effects of host herbivory on parasitic plants, and the potential mechanisms underlying such effects, are not well known. We conducted a greenhouse study to ask whether gypsy moth (Lymantria dispar) damage,...

Vertical profile data of light transmission in Atlantic forests along a disturbance gradient

S. Fauset, M.U. Gloor, M.A.P. Aidar, H.C. Freitas, N.M. Fyllas, C.A. Joly, M.A. Marabesi, A.L.C. Rochelle, A. Shenkin & S.A. Vieira
The data set contains vertical profiles of diffuse light transmittance measured within six forest plots in montane Atlantic forest, São Paulo state, Brazil. The plots measured include intact, previously logged and secondary forest in a large continuous forest block of the Serra do Mar State Park (Parque Estadual de Serra do Mar), and two forest fragments outside the park. In each plot 10 - 12 individual light profiles were recorded; the data set contains these...

Data from: Historical amphibian declines and extinctions in Brazil linked to chytridiomycosis

Tamilie Carvalho, C. Guilherme Becker & Luis Felipe Toledo
The recent increase in emerging fungal diseases is causing unprecedented threats to biodiversity. The origin of spread of the frog-killing fungus Batrachochytrium dendrobatidis (Bd) is a matter of continued debate. To date, the historical amphibian declines in Brazil could not be attributed to chytridiomycosis; the high diversity of hosts coupled with the presence of several Bd lineages predating the reported declines raised the hypothesis that a hypervirulent Bd genotype spread from Brazil to other continents...

Data from: Plant defences limit herbivore population growth by changing predator–prey interactions

Mônica F. Kersch-Becker, André Kessler & Jennifer S. Thaler
Plant quality and predators are important factors affecting herbivore population growth, but how they interact to regulate herbivore populations is not well understood. We manipulated jasmonate-induced plant resistance, exposure to the natural predator community and herbivore density to test how these factors jointly and independently affect herbivore population growth. On low-resistance plants, the predator community was diverse and abundant, promoting high predator consumption rates. On high-resistance plants, the predator community was less diverse and abundant,...
