Deep reefs are not refugium for shallow-water fish communities in the southwestern Atlantic

Aline Medeiros, Beatrice Ferreira, Fredy Alvarado, Ricardo Betancur-R, Marcelo Soares & Bráulio Santos
1. The deep reef refugia hypothesis (DRRH) predicts that deep reef ecosystems may act as refugium for the biota of disturbed shallow waters. Because deep reefs are amongst the most understudied habitats on Earth, formal tests of the DRRH remain scarce. If the DRRH is valid at the community level, the diversity of species, functions and lineages of fish communities of shallow reefs should be encapsulated in deep reefs. 2. We tested the DRRH by...

Data from: Metropolitan lizards? Urbanization gradient and the density of lagartixas (Tropidurus hispidus) in a tropical city

Antonio C. De Andrade
Urbanization, with its cohort of environmental stressors, has a dramatic effect on wildlife, causing loss of biodiversity and decline in population abundance customarily associated with increasing levels of impervious surface and fragmentation of native habitats. Some studies suggest that faunal species from open habitats, and with higher abundance in natural environments, seem more likely to tolerate and live in urban environments. Here I evaluate how the level of urbanization affects lagartixas (Tropidurus hispidus) one of...

Does genome size increase with water depth in marine fishes?

Aline Medeiros, Bráulio Santos & Ricardo Betancur-R
A growing body of research suggests that genome size in animals can be affected by ecological factors. Half a century ago, Ebeling et al. (1971; EEA71) proposed that genome size increases with depth in some teleost fish groups and discussed a number of biological mechanisms that may explain this pattern (e.g., passive accumulation, adaptive acclimation). Using phylogenetic comparative approaches, we revisit this hypothesis based on genome size and ecological data from up to 708 marine...

Congruence of local ecological knowledge (LEK)-based methods and line-transect surveys in estimating wildlife abundance in Amazonian forests

Franciany Braga-Pereira
1) Effective estimation of wildlife population abundance is an important component of population monitoring, and ultimately essential for the development of conservation actions. Diurnal line transect surveys are one of the most applied methods for abundance estimations. Local ecological knowledge (LEK) is empirically acquired through the observation of ecological processes by local people. LEK-based methods have only been recognized as valid scientific methods for surveying fauna abundance in the last three decades. However, the agreement...

The combined role of dispersal and niche evolution in the diversification of Neotropical lizards

Fernanda P. Werneck, Yumi Sheu, Juan P. Zurano, Marco A. Ribeiro-Junior, Teresa C. Ávila-Pires, Miguel T. Rodrigues & Guarino R. Colli
Ecological requirements and environmental conditions can influence diversification across temporal and spatial scales. Understanding the role of ecological niche evolution under phylogenetic contexts provides insights on speciation mechanisms and possible responses to future climatic change. Large-scale phyloclimatic studies on the megadiverse Neotropics, where biomes with contrasting vegetation types occur in narrow contact, are rare. We integrate ecological and biogeographic data with phylogenetic comparative methods, to investigate the relative roles of biogeographic events and niche divergence...

Data from - A new tale of lost tails: correlates of tail breakage in the worm lizard Amphisbaena vermicularis

Mario R. Moura, Jhonny J. M. Guedes & Henrique C. Costa
Predator-prey interactions are important evolutionary drivers of defensive behaviours, but they are usually difficult to record. This lack of data on natural history and ecological interactions of species can be overcome through museum specimens, at least for some reptiles. When facing aggressive interactions, reptile species may exhibit the defensive behaviour of autotomy by losing the tail, which is also known as ‘urotomy’. The inspection of preserved specimens for scars of tail breakage can reveal possible...

Data from: Estimating synchronous demographic changes across populations using hABC and its application for a herpetological community from northeastern Brazil

Marcelo Gehara, Adrian Antoinio Garda, Fernanda P. Werneck, Eliana F. Oliveira, Emanuel M. Da Fonseca, Felipe Camurugi, Felipe De M. Magalhães, Flavia Mol Lanna, Jack W. Sites, Ricardo Marques, Ricardo Silveira-Filho, Vinícius A. São-Pedro, Guarino R. Colli, Gabriel C. Costa & Frank T. Burbrink
Many studies propose that Quaternary climatic cycles contracted and /or expanded the ranges of species and biomes. Strong expansion-contraction dynamics of biomes presume concerted demographic changes of associated fauna. The analysis of temporal concordance of demographic changes can be used to test the influence of Quaternary climate on diversification processes. Hierarchical approximate Bayesian computation (hABC) is a powerful and flexible approach that models genetic data from multiple species, and can be used to estimate the...

Data from: Revisiting the measurement of anomie

Ali Teymoori, Jolanda Jetten, Brock Bastian, Amarina Ariyanto, Frédérique Autin, Nadia Ayub, Constantina Badea, Tomasz Besta, Fabrizio Butera, Rui Costa-Lopes, Lijuan Cui, Carole Fantini, Gillian Finchilesc, Lowell Gaertner, Mario Gollwitzer, Ángel Gómez, Roberto González, Ying Yi Hong, Dorthe Høj Jensen, Minoru Karasawa, Thomas Kessler, Olivier Klein, Marcus Lima, Tuuli Anna Mähönen, Laura Megevand … & Gillian Finchilescu
Sociologists coined the term "anomie" to describe societies that are characterized by disintegration and deregulation. Extending beyond conceptualizations of anomie that conflate the measurements of anomie as 'a state of society' and as a 'state of mind', we disentangle these conceptualizations and develop an analysis and measure of this phenomenon focusing on anomie as a perception of the 'state of society'. We propose that anomie encompasses two dimensions: a perceived breakdown in social fabric (i.e.,...

Functional biogeography of Neotropical moist forests: trait-climate relationships and assembly patterns of tree communities

Bruno Pinho, Marcelo Tabarelli, Cajo Ter Braak, S. J. Wright, Victor Arroyo-Rodriguez, Maíra Benchimol, Bettina Engelbrecht, Simon Pierce, Peter Hietz, Bráulio Santos, Carlos Peres, Sandra Müller, Ian Wright, Frans Bongers, Madelon Lohbeck, Ülo Niinemets, Martijn Slot, Steven Jansen, Davi Jamelli, Renato Augusto Ferreira De Lima, Nathan Swenson, Richard Condit, Jos Barlow, Ferry Slik, Manuel Hernández-Ruedas … & Felipe Melo
Aim: Here we examine the functional profile of regional tree species pools across the latitudinal distribution of Neotropical moist forests, and test trait-climate relationships among local communities. We expected opportunistic strategies (acquisitive traits, small seeds) to be overrepresented in species pools further from the equator due to long-term instability, but also in terms of abundance in local communities in currently wetter, warmer and more seasonal climates. Location: Neotropics. Time period: Recent. Major taxa studied: Trees....

Ecological and biogeographic processes drive the proteome evolution of snake venom

Tuany Siqueira-Silva, Luiz Lima, Jônatas Chaves-Silveira, Talita Amado, Julian Naipauer, Pablo Riul & Pablo Martinez
The emergence of venom is an evolutionary innovation that favored the diversification and survival of snakes. The composition of snake venoms is known in detail from venom gland proteomic data. However, there is still a gap of knowledge about the forces that lead to the expression of different toxins in different proportions in the venom cocktail across space and time. LOCATION World. TIME PERIOD Modern. MAJOR TAXA STUDIED Elapidae and Viperidae. We integrated proteomic data...

Data from: The anti-predator role of within-nest emergence synchrony in sea turtle hatchlings

Robson G. Santos, Hudson Tercio Pinheiro, Agnaldo Silva Martins, Pablo Riul, Soraya Christina Bruno, Fredric J. Janzen & Christos C. Ioannou
Group formation is a common behaviour among prey species. In egg-laying animals, despite the various factors that promote intra-clutch variation leading to asynchronous hatching and emergence from nests, synchronous hatching and emergence occurs in many taxa. This synchrony may be adaptive by reducing predation risk, but few data are available in any natural system, even for iconic examples of the anti-predator function of group formation. Here, we show for the first time that increased group...

Data from: Dynamics of coral reef benthic assemblages of the Abrolhos Bank, eastern Brazil: inferences on natural and anthropogenic drivers

Ronaldo B. Francini-Filho, Ericka O. C. Coni, Pedro M. Meirelles, Gilberto M. Amado-Filho, Fabiano L. Thompson, Guilherme H. Pereira-Filho, Alex C. Bastos, Douglas P. Abrantes, Camilo M. Ferreira, Fernando Z. Gibran, Arthur Z. Güth, Paulo Y. G. Sumida, Nara L. Oliveira, Les Kaufman, Carolina V. Minte-Vera & Rodrigo L. Moura
The Abrolhos Bank (eastern Brazil) encompasses the largest and richest coral reefs of the South Atlantic. Coral reef benthic assemblages of the region were monitored from 2003 to 2008. Two habitats (pinnacles’ tops and walls) were sampled per site with 3-10 sites sampled within different reef areas. Different methodologies were applied in two distinct sampling periods: 2003-2005 and 2006-2008. Spatial coverage and taxonomic resolution were lower in the former than in the latter period. Benthic...
