Mapping differences in mammalian distributions and diversity using environmental DNA from rivers

Allan McDevitt, Holly Broadhurst, Luke Gregory, Emma Bleakley, Joseph Perkins, Jenna Lavin, Polly Bolton, Samuel Browett, Claire Howe, Natalie Singleton, Darren Tansley & Naiara Sales
Finding more efficient ways to monitor, and estimate the diversity of, mammalian communities is a major step towards their management and conservation. Environmental DNA (eDNA) from river water has recently been shown to be a viable method for biomonitoring mammalian communities. Yet, most of the studies to date have focused on the potential for eDNA to detect individual species, with little focus on describing patterns of community diversity and structure. In this study, we focus...

As donas da Zambézia na ficção narrativa: da imaginação colonial à imaginação nacional

Fátima Mendonça
O texto analisa a forma como as chamadas Donas da Zambézia e os acontecimentos históricos em que participaram, são representados quer na ficção colonial portuguesa quer em narrativas pós-coloniais da autoria de escritores moçambicanos. Pretende mostrar, com o exemplo de Zambeziana, publicado em 1927 em Portugal, a intersecção existente entre o discurso exótico e o discurso colonial, incidindo sobre os tópicos raciais e sexuais, entre outros. Numa perspectiva comparada mostra igualmente como os mesmos acontecimentos...

Para uma educação por vir

Tiago Almeida & Jorge Ramos do Ó
Ao aceitar o convite para produzir um texto que fizesse parte deste livro, ficámos face a um desafio duplo. Por um lado, escrever sobre algo que se relacionasse com o Mestrado em Educação Artística da Escola Superior de Educação de Lisboa e, por outro, que permitisse conciliar duas mãos na tecedura do texto. Na tentativa de responder a estes dois desafios propusemo-nos pensar o que seria uma educação por vir que, por oposição a uma...

From performance curves to performance surfaces: Interactive effects of temperature and oxygen availability on aerobic and anaerobic performance in the common wall lizard

Rory Telemeco, Eric Gangloff, G. Antonio Cordero, Essie Rodgers & Fabien Aubret
1. Accurately predicting the responses of organisms to novel or changing environments requires the development of ecologically-appropriate experimental methodology and process-based models. 2. For ectotherms, thermal performance curves (TPCs) have provided a useful framework to describe how organismal performance is dependent on temperature. However, this approach often lacks a mechanistic underpinning, which limits our ability to use thermal performance curves predictively. Further, thermal dependence varies across traits, and performance is also limited by additional abiotic...

Global potential invasion maps of traded birds under climate and land-cover change

Babak Naimi, César Capinha, Joana Ribeiro, Carsten Rahbek, Diederik Strubbe, Luís Reino & Miguel Araujo
Biological invasions rank among the top five threatening factors affecting biodiversity, but ongoing changes in climate and land cover might exacerbate risks. We used species distribution models for 609 traded bird species on the CITES list to examine the combined effects of projected climate change and land-cover change worldwide on the potential range expansion of bird species with commercial value as pets. The maps of potential invasion (may be inferred as the invasion risk) have...

Data from: Phylogeography, genetic structure and population divergence time of cheetahs in Africa and Asia: evidence for long-term geographic isolates

Pauline Charruau, Carlos Fernandes, Pablo Orozco-TerWengel, Joris Peters, Luke Hunter, H. Ziaie, A. Jourabchian, H. Jowkar, Georges Schaller, Stephane Ostrowski, Paul Vercammen, Thierry Grange, Christian Schlötterer, Antoinette Kotze, Eva-Maria Geigl, Chris Walzer & Pamela A. Burger
The cheetah (Acinonyx jubatus) has been described as a species with low levels of genetic variation. This has been suggested to be the consequence of a demographic bottleneck 10 000–12 000 years ago (ya) and also led to the assumption that only small genetic differences exist between the described subspecies. However, analysing mitochondrial DNA and microsatellites in cheetah samples from most of the historic range of the species we found relatively deep phylogeographic breaks between...

Data from: Incipient allochronic speciation in the pine processionary moth Thaumetopoea pityocampa (Lepidoptera: Notodontidae)

Helena Santos, Christian Burban, Jerome Rousselet, Jean-Pierre Rossi, Manuela Branco & Carole Kerdelhué
A plausible case of allochronic differentiation, where barrier to gene flow is primarily due to a phenological shift, was recently discovered in Portugal for the pine processionary moth Thaumetopoea pityocampa. Previous results suggested that the observed "summer population" (SP) originated from the sympatric winter population (WP). Our objectives were to finely analyse these patterns and test their stability in time, through field monitoring and genetic analyses of larvae and adults across different years. Reproductive activity...

Data from: Evolution of mating behaviour between two populations adapting to common environmental conditions

Margarida Bárbaro, Mário S. Mira, Inês Fragata, Pedro Simões, Margarida Lima, Miguel Lopes-Cunha, Bárbara Kellen, Josiane Santos, Susana A. M. Varela, Margarida Matos & Sara Magalhães
Populations from the same species may be differentiated across contrasting environments, potentially affecting reproductive isolation among them. When such populations meet in a novel common environment, this isolation may be modified by biotic or abiotic factors. Curiously, the latter have been overlooked. We filled this gap by performing experimental evolution of three replicates of two populations of Drosophila subobscura adapting to a common laboratorial environment, and simulated encounters at three time points during this process....

Data from: Detection of tephra layers in Antarctic sediment cores with hyperspectral imaging

Ismael F. Aymerich, Marc Oliva, Santiago Giralt & Julio Martín-Herrero
Tephrochronology uses recognizable volcanic ash layers (from airborne pyroclastic deposits, or tephras) in geological strata to set unique time references for paleoenvironmental events across wide geographic areas. This involves the detection of tephra layers which sometimes are not evident to the naked eye, including the so-called cryptotephras. Tests that are expensive, time-consuming, and/or destructive are often required. Destructive testing for tephra layers of cores from difficult regions, such as Antarctica, which are useful sources of...

Data from: Wing trait-inversion associations in Drosophila subobscura can be generalized within continents, but may change through time

Pedro Simoes, Inês Fragata, Miguel Lopes-Cunha, Margarida Lima, Bárbara Kellen, Margarida Bárbaro, Mauro Santos & Margarida Matos
Clinal variation is one of the most emblematic examples of the action of natural selection at a wide geographical range. In Drosophila subobscura parallel clines in body size and inversions, but not in wing shape, were found in Europe and South and North America. Previous work has shown that a bottleneck effect might be largely responsible for differences in wing trait-inversions association between one European and one South American population. One question still unaddressed is...

Data from: Semi-permeable species boundaries in Iberian barbels (Barbus and Luciobarbus, Cyprinidae)

Hugo F. Gante, Ignacio Doadrio, Maria Judite Alves & Thomas E. Dowling
Background: The evolution of species boundaries and the relative impact of selection and gene flow on genomic divergence are best studied in populations and species pairs exhibiting various levels of divergence along the speciation continuum. We studied species boundaries in Iberian barbels, Barbus and Luciobarbus, a system of populations and species spanning a wide degree of genetic relatedness, as well as geographic distribution and range overlap. We jointly analyze multiple types of molecular markers and...

Data from: An holistic ecological analysis of the diet of Cory’s shearwaters using prey morphological characters and DNA barcoding

Hany Alonso, José Pedro Granadeiro, Silke Waap, José Xavier, William O. C. Symondson, Jaime A. Ramos & Paulo Catry
Knowledge of the dietary choices and trophic niches of organisms is the key to understanding their roles in ecosystems. In seabird diet studies, prey identification is a difficult challenge, often yielding results with technique-specific biases. Additionally, sampling efforts are often not extensive enough to reveal intra-populational variation. Immature animals, which may constitute up to 50% of a population, may occupy a significantly different trophic niche to more-experienced birds, but this remains largely unexplored. We investigated...

Data from: Influence of plant-pollinator interactions on the assembly of plant and hummingbird communities

Marina Wolowski, Luísa G. Carvalheiro & Leandro Freitas
Understanding how ecological processes structure species assemblages is a central issue in community ecology. While the influence of plant–pollinator interactions on each other's evolution is well recognized, their role in the assembly of interdependent communities of plants and pollinators is still unclear. Using data from seven communities of hummingbirds and plants that they pollinate from two tropical rain forest types (lowland and montane), we evaluated phylogenetic relationships and signal of functional traits, over space and...

Data from: Spatial patterns of self-recruitment of a coral reef fish in relation to island-scale retention mechanisms

Ricardo Beldade, Sally J. Holbrook, Russell J. Schmitt, Serge Planes & Giacomo Bernardi
Oceanographic features influence the transport and delivery of marine larvae, and physical retention mechanisms, such as eddies, can enhance self-recruitment (i.e. the return of larvae to their natal population). Knowledge of exact locations of hatching (origin) and settlement (arrival) of larvae of reef animals provides a means to compare observed patterns of self-recruitment ‘connectivity’ with those expected from water circulation patterns. Using parentage inference based on multiple sampling years in Moorea, French Polynesia, we describe...

Data from: Dispersal and group formation dynamics in a rare and endangered temperate forest bat (Nyctalus lasiopterus, Chiroptera: Vespertilionidae)

João D. Santos & Christoph F. J. Meyer
For elusive mammals like bats, colonization of new areas and colony formation are poorly understood, as is their relationship with the genetic structure of populations. Understanding dispersal and group formation behaviors is critical not only for a better comprehension of mammalian social dynamics, but also for guiding conservation efforts of rare and endangered species. Using nuclear and mitochondrial markers, we studied patterns of genetic diversity and differentiation among and within breeding colonies of giant noctule...

Data from: Climate modifies response of non-native and native species richness to nutrient enrichment

Habacuc Flores-Moreno, Peter B. Reich, Eric M. Lind, Lauren L. Sullivan, Eric W. Seabloom, Laura Yahdjian, Andrew S. MacDougall, Lara G. Reichmann, Juan Alberti, Selene Báez, Jonathan D. Bakker, Marc W. Cadotte, Maria C. Caldeira, Enrique J. Chaneton, Carla M. D'Antonio, Philip A. Fay, Jennifer Firn, Nicole Hagenah, W. Stanley Harpole, Oscar Iribarne, Kevin P. Kirkman, Johannes M. H. Knops, Kimberly J. La Pierre, Ramesh Laungani, Andrew D. B. Leakey … & Elizabeth T. Borer
Ecosystem eutrophication often increases domination by non-natives and causes displacement of native taxa. However, variation in environmental conditions may affect the outcome of interactions between native and non-native taxa in environments where nutrient supply is elevated. We examined the interactive effects of eutrophication, climate variability and climate average conditions on the success of native and non-native plant species using experimental nutrient manipulations replicated at 32 grassland sites on four continents. We hypothesized that effects of...

Data from: Structure and functioning of intertidal food webs along an avian flyway: a comparative approach using stable isotopes

Teresa Catry, Pedro M. Lourenço, Ricardo J. Lopes, Camilo Carneiro, José A. Alves, Joana Costa, Hamid Rguibi-Idrissi, Stuart Bearhop, Theunis Piersma & José P. Granadeiro
Food webs and trophic dynamics of coastal systems have been the focus of intense research throughout the world, as they prove to be critical in understanding ecosystem processes and functions. However, very few studies have undertaken a quantitative comparison of entire food webs from a key consumer perspective across a broad geographical area, limiting relevant comparisons among systems with distinct biotic and abiotic components. We investigate the structure and functioning of food webs in four...

Data from: Does sex matter? Gender-specific responses to forest fragmentation in Neotropical bats

Ricardo Rocha, Diogo F. Ferreira, Adrià López-Baucells, Fabio Z. Farneda, Joao M.B. Carreiras, Jorge M. Palmeirim & Christoph F. J. Meyer
Understanding the consequences of habitat modification on wildlife communities is central to the development of conservation strategies. However, albeit male and female individuals of numerous species are known to exhibit differences in habitat use, sex-specific responses to habitat modification remain little explored. Here, we used a landscape-scale fragmentation experiment to assess, separately for males and females, the effects of fragmentation on the abundance of Carollia perspicillata and Rhinophylla pumilio, two widespread Neotropical frugivorous bats. We...

Data from: Mauritius on fire: tracking historical human impacts on biodiversity loss

William D. Gosling, Jona De Kruif, Sietze J. Norder, Erik J. De Boer, Henry Hooghiemstra, Kenneth F. Rijsdijk, Crystal N.H. McMichael & Crystal N. H. McMichael
Fire was rare on Mauritius prior to human arrival (AD 1598); subsequently three phases of elevated fire activity occurred: c. 1630-1747, 1787-1833, and 1950-modern. Elevated fire frequency coincided with periods of high human impact evidenced from the historical record, and is linked to the extinction of island endemics.

Data from: Ocean warming and acidification may challenge the riverward migration of glass eels

Francisco O. Borges, Catarina P. Santos, Eduardo Sampaio, Cátia Figueiredo, José Ricardo Paula, Carlos Antunes, Rui Rosa & Tiago F. Grilo
The dramatic decline of European eel (Anguilla anguilla) populations over recent decades has attracted considerable attention and concern. Furthermore, little is known concerning the sensitivity of eel’s early stages to projected future environmental change. Here we investigated, for the first time, the potential combined effects of ocean warming (OW; ∆ + 4oC; 18oC) and acidification (OA; ∆ - 0.4 pH units) on the survival and migratory behaviour of A. anguilla glass eels, namely their preference...

Data from: Drivers of power line use by white storks: a case study of birds nesting on anthropogenic structures

Francisco Moreira, Ricardo C. Martins, Ines Catry & Marcello D'Amico
1. Anthropogenic structures are mainly known to have negative impacts on wildlife populations but sometimes arethey can be beneficial. Power lines are a main driver of bird mortality through collision or electrocution, but electricity pylons are also commonly used for nest building by some species. Birds and nests cause power outages that need to be tackled by electricity companies. However, the use of pylons by threatened species provides an opportunity for conservation purposes. 2. In...

Data from: How much starvation, desiccation and oxygen depletion can Drosophila melanogaster tolerate before its upper thermal limits are affected?

Tommaso Manenti, Tomás Rocha Cunha, Jesper Givskov Sørensen & Volker Loeschcke
Heat tolerance is commonly assessed as the critical thermal maximum (CTmax) using the dynamic method exposing organisms to a gradually increasing (ramping) temperature until organisms fall into a coma. The CTmax estimate is dependent on the ramping rate, with decreased rates leading to longer treatments and ultimately lower CTmax estimates. There is a current discussion surrounding the physiological dynamics of the effect of the time of exposure by temperature interaction on these estimates. Besides temperature...
