Data from: Incorporating animal spatial memory in step selection functions

Luiz Gustavo R. Oliveira-Santos, James D. Forester, Ubiratan Piovezan, Walfrido M. Tomas & Fernando A. S. Fernandez
Memory is among the most important and neglected forces that shapes animal movement patterns. Research on the movement-memory interface is crucial to understand how animals use spatial learning to navigate across space because memory-biased navigation is directly linked to animals’ space use and home range behaviour; however, because memory cannot be measured directly, it is difficult to account for. Here, we incorporated spatial memory into Step Selection Functions (SSF) to understand how resource selection and...

Data from: Predator kairomones change food web structure and function, regardless of cues from consumed prey

Nicholas A. C. Marino, Diane S. Srivastava & Vinicius F. Farjalla
Predation risk in aquatic systems is often assessed by prey through chemical cues, either those released by prey or by the predator itself. Many studies on predation risk focus on simple pairwise interactions, with only a few studies examining community-level and ecosystem responses to predation risk in species-rich food webs. Further, of these few community-level studies, most assume that prey primarily assess predation risk through chemical cues from consumed prey, even heterospecific prey, rather than...

Data from: Which landscape size best predicts the influence of forest cover on restoration success? – A global meta-analysis on the scale of effect

Renato Crouzeilles & Michael Curran
Landscape context is a strong predictor of species persistence, abundance and distribution, yet its influence on the success of ecological restoration remains unclear. Thus, a primary question arises: which landscape size best predicts the effects of forest cover on restoration success? To answer this question, we conducted a global meta-analysis for biodiversity (mammals, birds, invertebrates, herpetofauna and plants) and measures of vegetation structure (cover, density, height, biomass and litter). Response ratios were calculated for comparisons...

Data from: Diversification of the genus Anopheles and a Neotropical clade from the Late Cretaceous

Lucas A. Freitas, Claudia A. M. Russo, Carolina M. Voloch, Olívio C. F. Mutaquiha, Lucas P. Marques & Carlos G. Schrago
The Anopheles genus is a member of the Culicidae family and consists of approximately 460 recognized species. The genus is composed of 7 subgenera with diverse geographical distributions. Despite its huge medical importance, a consensus has not been reached on the phylogenetic relationships among Anopheles subgenera. We assembled a comprehensive dataset comprising the COI, COII and 5.8S rRNA genes and used maximum likelihood and Bayesian inference to estimate the phylogeny and divergence times of six...

Data from: Revised classification and evolution of leucotrichiine microcaddisflies (Trichoptera: Hydroptilidae) based on morphological and molecular data

Allan P. M. Santos, Jorge L. Nessimian & Daniela M. Takiya
Hydroptilidae constitute the most diverse caddisfly family, with over 2000 species known from every habitable continent. Leucotrichiinae are exclusively New World microcaddisflies, currently including over 200 species and 17 genera. Phylogenetic analyses of Leucotrichiinae relationships based on 114 morphological characters and 2451 molecular characters from DNA sequences were conducted. DNA sequences analysed were from one mitochondrial gene, cytochrome oxidase I (653 bp), and four nuclear genes, carbamoylphosphate synthase (802 bp), elongation factor 1α (352 bp),...

Data from: Resources alter the structure and increase stochasticity in bromeliad microfauna communities

Jana S. Petermann, Pavel Kratina, Nicolas A. C. Marino, A. Andrew M. MacDonald, Diane S. Srivastava & Nicholas A. C. Marino
Although stochastic and deterministic processes have been found to jointly shape structure of natural communities, the relative importance of both forces may vary across different environmental conditions and across levels of biological organization. We tested the effects of abiotic environmental conditions, altered trophic interactions and dispersal limitation on the structure of aquatic microfauna communities in Costa Rican tank bromeliads. Our approach combined natural gradients in environmental conditions with experimental manipulations of bottom-up interactions (resources), top-down...

Data from: Cruzipain activates latent TGF-β from host cells during T. cruzi invasion

Patrícia Mello Ferrão, Claudia Masini D'Avila-Levy, Tania Cremonini Araujo-Jorge, Wim Maurits Degrave, Antônio Da Silva Gonçalves, Luciana Ribeiro Garzoni, Ana Paula Lima, Jean Jacques Feige, Sabine Bailly, Leila Mendonça-Lima & Mariana Caldas Waghabi
Several studies indicate that the activity of cruzipain, the main lysosomal cysteine peptidase of Trypanosoma cruzi, contributes to parasite infectivity. In addition, the parasitic invasion process of mammalian host cells is described to be dependent on the activation of the host TGF-β signaling pathway by T. cruzi. Here, we tested the hypothesis that cruzipain could be an important activator of latent TGF-β and thereby trigger TGF-β-mediated events crucial for the development of Chagas disease. We...

Data from: Interactive effects of predation risk and conspecific density on the nutrient stoichiometry of prey

Rafael D. Guariento, Luciana S. Carneiro, Jaqueilto S. Jorge, Angélica N. Borges, Francisco A. Esteves, Adriano Caliman & Jaqueiuto S. Jorge
The mere presence of predators (i.e., predation risk) can alter consumer physiology by restricting food intake and inducing stress, which can ultimately affect prey-mediated ecosystem processes such as nutrient cycling. However, many environmental factors, including conspecific density, can mediate the perception of risk by prey. Prey conspecific density has been defined as a fundamental feature that modulates perceived risk. In this study, we tested the effects of predation risk on prey nutrient stoichiometry (body and...

Data from: Patterns of vertebrate diversity and protection in Brazil

Clinton N. Jenkins, Maria Alice S. Alves, Alexandre Uezu & Mariana M. Vale
Most conservation decisions take place at national or finer spatial scales. Providing useful information at such decision-making scales is essential for guiding the practice of conservation. Brazil is one of the world’s megadiverse countries, and consequently decisions about conservation in the country have a disproportionate impact on the survival of global biodiversity. For three groups of terrestrial vertebrates (birds, mammals, and amphibians), we examined geographic patterns of diversity and protection in Brazil, including that of...

Data from: Edge effects and geometric constraints: a landscape-level empirical test

Suzy E. Ribeiro, Jayme A. Prevedello, Ana Cláudia Delciellos & Marcus Vinicius Vieira
Edge effects are pervasive in landscapes yet their causal mechanisms are still poorly understood. Traditionally, edge effects have been attributed to differences in habitat quality along the edge-interior gradient of habitat patches, under the assumption that no edge effects would occur if habitat quality was uniform. This assumption was questioned recently after the recognition that geometric constraints tend to reduce population abundances near the edges of habitat patches, the so-called “geometric edge effect” (GEE). Here...
