Data from: Anthropogenic disturbance of tropical forests threatens pollination services to açaí palm in the Amazon river delta

Alistair John Campbell, Luísa Gigante Carvalheiro, Marcia Motta Maués, Rodolfo Jaffé, Tereza Cristina Giannini, Madson Antonio Benjamin Freitas, Beatriz Woiski Texeira Coelho & Cristiano Menezes
The açaí palm Euterpe oleracea Mart. in the Amazon river delta has seen rapid expansion to meet increased demand for its fruit. This has been achieved by transforming lowland forest habitats (floodplains) into simplified agroforests and intensive plantation in upland areas. As açaí palm makes an important contribution to the economy and food security of local communities, identifying management approaches that support biodiversity and ecosystem processes that underpin fruit production on açaí farms is essential....

M. Groenen, Lusheng Huang & Hendrik-Jan Megens
Background: Pigs were domesticated independently in Eastern and Western Eurasia early during the agricultural revolution, and have since been transported and traded across the globe. Here, we present a worldwide survey on 60K genome-wide single nucleotide polymorphism (SNP) data for 2093 pigs, including 1839 domestic pigs representing 122 local and commercial breeds, 215 wild boars, and 39 out-group suids, from Asia, Europe, America, Oceania and Africa. The aim of this study was to infer global...

Data from: Mate choice driven by genome in an allopolyploid fish complex

Miguel Morgado-Santos, Maria Filomena Magalhães, Luís Vicente & Maria João Collares-Pereira
Nonsexual complexes which lack typical reproductive isolation and show multiple conspecific and heterospecific mating options among hybrids and parental species are excellent models to study mate choice based on genetics. The allopolyploid fish complex Squalius alburnoides includes multiple fertile male and female genomotypes reproducing among each other and with the sympatric species of the Squalius genus. We used this hybridogenetic complex to study the relationship between mate preference and mates’ genetic background, focusing on a...

Data from: Riparian plant guilds become simpler and most likely fewer following flow regulation

María D. Bejarano, Christer Nilsson & Francisca C. Aguiar
1. River regulation affects riparian systems worldwide and conservation and restoration efforts are essential to retain biodiversity, and the functioning and services of riverine ecosystems. Effects of regulation on plant species richness have been widely addressed, but the filtering effect of regulation on guilds has received less attention. 2. We used a functional trait approach to identify adaptive plant strategies through regulation-tolerant traits and predict shifts of riparian vegetation communities in response to regulation. We...

Data from: Rare events of massive plant reproductive investment lead to long-term density-dependent reproductive success

Magdalena Żywiec, Mateusz Ledwoń, Jan Holeksa, Piotr Seget, Barbara Łopata & Jose M. Fedriani
1. The level of reproductive investment and density and distance dependent (DDD) processes are major determinants of plant reproductive output. The reproductive investment of a plant population varies temporally, but whether and how density- and distance-dependent processes are affected by population-level reproductive investment is a puzzle. 2. We used a spatially explicit approach in order to examine DDD effects on Sorbus acuparia crop sizes for a continuous period of 16 years. Our special interest was...

Data from: Long term on-farm participatory maize breeding by stratified mass selection retains molecular diversity while improving agronomic performance

Mara Lisa Alves, Maria Belo, Bruna Carbas, Cláudia Brites, Manuel Paulo, Pedro Mendes-Moreira, Carla Brites, Maria Do Rosário Bronze, Zlatko Šatović & Maria Carlota Vaz Patto
Modern maize breeding programs gave rise to genetically uniform varieties that can affect maize's capacity to cope with increasing climate unpredictability. Maize populations, genetically more heterogeneous, can evolve and better adapt to a broader range of edaphic-climatic conditions. These populations usually suffer from low yields; it is therefore desirable to improve their agronomic performance while maintaining their valuable diversity levels. With this objective, a long-term participatory breeding/on-farm conservation program was established in Portugal. In this...

We quantified how abundance and...

Data from: History, geography, and host use shape genome-wide patterns of genetic variation in the redheaded pine sawfly (Neodiprion lecontei)

Robin K. Bagley, Vitor C. Sousa, Matthew L. Niemiller & Catherine R. Linnen
Divergent host use has long been suspected to drive population differentiation and speciation in plant-feeding insects. Evaluating the contribution of divergent host use to genetic differentiation can be difficult, however, as dispersal limitation and population structure may also influence patterns of genetic variation. In this study, we use double-digest restriction-associated DNA (ddRAD) sequencing to test the hypothesis that divergent host use contributes to genetic differentiation among populations of the redheaded pine sawfly (Neodiprion lecontei), a...

Utilizing field collected insects for next generation sequencing: effects of sampling, storage, and DNA extraction methods

Kimberly Ballare, Nathaniel Pope, Antonio Castilla, Sarah Cusser, Richard Metz & Shalene Jha
DNA sequencing technologies continue to advance the biological sciences, expanding opportunities for genomic studies of non-model organisms for basic and applied questions. Despite these opportunities, many next-generation sequencing protocols have been developed assuming a substantial quantity of high molecular weight DNA (>100 ng), which can be difficult to obtain for many study systems. In particular, the ability to sequence field-collected specimens that exhibit varying levels of DNA degradation remains largely unexplored. In this study we...

Explaining illness with evil: Pathogen prevalence fosters moral vitalism

Brock Bastian, Christin-Melanie Vauclair, Steve Loughnan, Paul Bain, Ashwini Ashokkumar, Maja Becker, Michal Bilewicz, Emma Collier-Baker, Carla Crespo, Paul W. Eastwick, Ronald Fischer, Malte Friese, Ángel Gómez, Valeschka M. Guerra, Jose Luis Castellanos Guevara, Katja Hanke, Nic Hooper, Li-Li Huang, Shi Junqi, Minoru Karasawa, Peter Kuppens, Siri Leknes, Müjde Peker, Cesar Pelay, Afoditi Pina … & William B. Swann
Pathogens represent a significant threat to human health leading to the emergence of strategies designed to help manage their negative impact. We examined how spiritual beliefs developed to explain and predict the devastating effects of pathogens and spread of infectious disease. Analysis of existing data in Studies 1 and 2 suggests that moral vitalism (beliefs about spiritual forces of evil) is higher in geographical regions characterized by historical higher levels of pathogens. Furthermore, drawing on...

Stable leaders pave the way for cooperation under time-dependent exploration rates

Flávio L. Pinheiro, Jorge M. Pacheco & Francisco C. Santos
The exploration of different behaviors is part of the adaptation repertoire of individuals to new environments. Here, we explore how the evolution of cooperative behavior is affected by the interplay between exploration dynamics and social learning, in particular when individuals engage on the Prisoner's Dilemma along the edges of a social network. We show that when the population undergoes a transition from strong to weak exploration rates a decline in the overall levels of cooperation...

Data from: Drosophila melanogaster larvae make nutritional choices that minimize developmental time

Marisa A. Rodrigues, Nelson E. Martins, Lara F. Balancé, Lara N. Broom, António J. S. Dias, Ana S. D. Fernandes, Fábio Rodrigues, Élio Sucena & Christen K. Mirth
Organisms from slime moulds to humans carefully regulate their macronutrient intake to optimize a wide range of life history characters including survival, stress resistance, and reproductive success. However, life history characters often differ in their response to nutrition, forcing organisms to make foraging decisions while balancing the trade-offs between these effects. To date, we have a limited understanding of how the nutritional environment shapes the relationship between life history characters and foraging decisions. To gain...

Data from: Using beta diversity to inform agricultural policies and conservation actions on Mediterranean farmland

Joana Santana, Miguel Porto, Luis Reino, Francisco Moreira, Paulo Flores Ribeiro, José Lima Santo, John T. Rotenberry & Pedro Beja
1. Spatial variation in species composition (β-diversity) is an important component of farmland biodiversity, which together with local richness (α-diversity) drives the number of species in a region (γ-diversity). However, β-diversity is seldom used to inform conservation, due to limited understanding of its responses to agricultural management, and lack of clear links between β-diversity changes and conservation outcomes. 2. We explored the value of β-diversity to guide conservation on farmland, by quantifying the contribution of...

Bat phylogenetic responses to regenerating Amazonian forests

Fábio Z. Farneda, Ricardo Rocha, Sabhrina Gita Aninta, Adrià López-Baucells, Erica M. Sampaio, Jorge M. Palmeirim, Paulo E. D. Bobrowiec, Cristian S. Dambros & Christoph F. J. Meyer
1. Throughout the tropics, regenerating secondary forests occupy vast areas previously cleared for agriculture and cattle ranching. However, despite the importance of regenerating forests in mitigating the pervasive negative consequences of forest loss and fragmentation on forest-associated biodiversity, longitudinal studies on species’ phylogenetic responses to matrix regeneration are rare. 2. We surveyed bats in continuous primary forest, primary forest fragments and in the regenerating secondary forest matrix of a whole-ecosystem Amazonian fragmentation experiment, ~15 and...

Data from: Community-level responses of African carnivores to prescribed burning

Laura Gigliotti, Goncalo Curveira-Santos, Rob Slotow, Craig Sholto-Douglas, Lourens Swanepoel & David Jachowski
Fires are common in many ecosystems worldwide, and are frequently used as a management tool. Although the responses of herbivores to fire have been well-studied, the responses of carnivores to fire remain unclear. In particular, post-fire habitat changes, and the associated changes in prey availability, might affect the coexistence or competition of carnivore species within the larger carnivore community, but few studies have focused on how fires influence multiple carnivore species simultaneously. Using South African...

Food talk: 40-Hz fin whale calls are associated with prey biomass

Miriam Romagosa, Sergi Pérez-Jorge, Irma Cascão, Helena Mouriño, Patrick Lehodey, Andreia Pereira, Tiago A. Marques, Luís Matias & Mónica A. Silva
Animals use varied acoustic signals that play critical roles in their lives. Understanding the function of these signals may inform about key life-history processes relevant for conservation. In the case of fin whales (Balaenoptera physalus), that produce different call types associated with different behaviours, several hypotheses have emerged regarding call function, but the topic still remains in its infancy. Here, we investigate the potential function of two fin whale vocalizations, the song-forming 20-Hz call and...

Data from: Genomic data and multi-species demographic modelling uncover past hybridization between currently allopatric freshwater species

Sofia L. Mendes, Miguel P. Machado, Maria M. Coelho & Vitor C. Sousa
Evidence for ancient interspecific gene flow through hybridization has been reported in many animal and plant taxa based on genetic markers. The study of genomic patterns of closely related species with allopatric distributions allows the assessment of the relative importance of vicariant isolating events and past gene flow. Here, we investigated the role of gene flow in the evolutionary history of four closely related freshwater fish species with currently allopatric distributions in western Iberian rivers...

Social learning by mate-choice copying increases dispersal and reduces local adaptation

Manuel Sapage, Susana A. M. Varela & Hanna Kokko
1. In heterogeneous environments, dispersal may be hampered not only by direct costs, but also because immigrants may be locally maladapted. While maladaptation affects both sexes, this cost may be modulated in females if they express mate preferences that are either adaptive or maladaptive in the new local population. 2. Dispersal costs under local adaptation may be mitigated if it is possible to switch to expressing traits of locally adapted residents. In a sexual selection...

The sources of variation for individual prey-to-predator size ratios

Jorge Henriques, Mariángeles Lacava, Celeste Guzman, Maria Pilar Gavín-Centol, Dolores Ruiz-Lupión, Eva De Mas, Sara Magalhães & Jordi Moya-Laraño
The relative body size at which predators are willing to attack prey, a key trait for predator-prey interactions, is usually considered invariant. However, this ratio can vary widely among individuals or populations. Identifying the range and origin of such variation is key to understanding the strength and constraints on selection in both predators and prey. Still, these sources of variation remain largely unknown. We filled this gap by measuring the genetic, maternal and environmental variation...

Ant taxonomic and functional beta-diversity

Clara Frasconi Wendt, Ana Ceia-Hasse, Alice Nunes, Robin Verble, Giacomo Santini, Mário Boieiro & Cristina Branquinho
The decomposition of beta-diversity (β-diversity) into its replacement (βrepl) and richness (βrich) components in combination with a taxonomic and functional approach, may help to identify processes driving community composition along environmental gradients. We aimed to understand which abiotic and spatial variables influence ant β-diversity and identify which processes may drive ant β-diversity patterns in Mediterranean drylands by measuring the percentage of variation in ant taxonomic and functional β-diversity explained by local environmental, regional climatic and...

Um olhar sobre a grande prematuridade: a investigação com bebés nascidos com menos de 32 semanas de gestação

Sandra Antunes, Marina Fuertes & João Moreira
Os bebés de pré-termo (com menos de 32 semanas) ou com muito baixo peso ao nascer (abaixo dos 1500g) apresentam um risco agravado de problemas de saúde e constitucionais, capazes de afetar o seu desenvolvimento. A taxa de sobrevivência de bebés com grande e extrema prematuridade aumentou na última década, com a melhoria dos cuidados peri e neonatais. Contudo, estes bebés enfrentam um significativo conjunto de problemas durante a fase perinatal, que podem fazer perigar...
