Data from: Life-history traits of Macrolophus pygmaeus with different prey foods

Serigne Sylla, Karamoko Diarra & Thierry Brévault
Macrolophus pygmaeus Rambur (Hemiptera: Miridae) is a generalist predatory mirid widely used in augmentative biological control of various insect pests in greenhouse tomato production in Europe, including the invasive tomato leafminer, Tuta absoluta (Meyrick) (Lepidoptera, Gelechiidae). However, its biocontrol efficacy often relies on the presence of alternative prey. The present study aimed at evaluating the effect of various prey foods (Ephestia kuehniella eggs, Bemisia tabaci nymphs, Tuta absoluta eggs and Macrosiphum euphorbiae nymphs) on some...

Data from: TipDatingBeast: an R package to assist the implementation of phylogenetic tip-dating tests using BEAST

Adrien Rieux & Camilo E. Khatchikian
Molecular tip-dating of phylogenetic trees is a growing discipline that uses DNA sequences sampled at different points in time to co-estimate the timing of evolutionary events with rates of molecular evolution. In this context, BEAST, a program for Bayesian analysis of molecular sequences, is the most widely used phylogenetic tool. Here, we introduce TipDatingBeast, an R package built to assist the implementation of various phylogenetic tip-dating tests using BEAST. TipDatingBeast currently contains two main functions....

Data from: Multilocus phylogeny and ecological differentiation of the “Eupelmus urozonus species group” (Hymenoptera, Eupelmidae) in the West-Palaearctic

Fadel Al Khatib, Astrid Cruaud, Lucian Fusu, Gwenaëlle Genson, Jean-Yves Rasplus, Nicolas Ris & Gérard Delvare
Background: The ecological differentiation of insects with parasitic life-style is a complex process that may involve phylogenetic constraints as well as morphological and/or behavioural adaptations. In most cases, the relative importance of these driving forces remains unexplored. We investigate here this question for the “Eupelmus urozonus species group” which encompasses parasitoid wasps of potential interest in biological control. This was achieved using seven molecular markers, reliable records on 91 host species and a proxy of...

Data from: Intraspecific trait variation across multiple scales: the leaf economics spectrum in coffee

Adam R. Martin, Bruno Rapidel, Olivier Roupsard, Karel Van Den Meersche, Elias De Melo Virginio Filho, Mirna Barrios & Marney E. Isaac
Understanding species differences in plant functional traits has been critical in developing a mechanistic understanding of terrestrial ecological processes. Greater attention is now being placed on understanding the extent, causes and consequences of intraspecific trait variation (ITV). ITV is especially important in governing ecological processes in cropping systems, where only a small number of species or genotypes exist in high abundances. However, it remains unclear if key principles of trait-based ecology – namely the leaf...

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: Past and present dynamics of sorghum and pearl millet diversity in Mount Kenya region

Vanesse Labeyrie, Monique Deu, Yann Dussert, Bernard Rono, Françoise Lamy, Charles Marangu, Dan Kiambi, Caroline Calatayud, Geo Coppens D’Eeckenbrugge, Thierry Robert, Christian Leclerc & Geo Coppens D'Eeckenbrugge
Crop populations in smallholder farming systems are shaped by the interaction of biological, ecological and social processes, occurring on different spatiotemporal scales. Understanding these dynamics is fundamental for the conservation of crop genetic resources. In this paper we investigated the processes involved in sorghum and pearl millet diversity dynamics on Mount Kenya. Surveys were conducted in ten sites distributed along two elevation transects and occupied by six ethnolinguistic groups. Varieties of both species grown in...

Data from: Forecasting potential emergence of zoonotic diseases in Southeast Asia: network analysis identifies key rodent hosts

Frédéric Bordes, Alexandre Caron, Kim Blasdell, Michel De Garine-Wichatitsky & Serge Morand
1. Within complex ecological systems, identifying animal species likely to play a key role in the emergence of infectious zoonotic diseases remains a major challenge. One approach consists of using information on current ecological and parasitological similarities among host species in order to predict the most likely pathways for future pathogen spillover. 2. Using field data acquired from 15 sympatric rodent species in various habitats in Thailand, Cambodia and Laos, we built networks based on...

Data from: Genetic diversification and dispersal of taro (Colocasia esculenta (L.) Schott)

Hana Chaïr, Renan E. Traore, Marie France Duval, Ronan Rivallan, Archana Mukherjee, Lawrence M. Aboagye, Willem J. Van Rensburg, Voahangy Andrianavalona, Miguel A.A. Pinheiro De Carvalho, Francisco Saborio, Made Sri Prana, Birte Komolong, Floriane Lawac & Vincent Lebot
Taro (Colocasia esculenta (L.) Schott) is widely distributed in tropical and sub-tropical areas. However, its origin, diversification and dispersal remain unclear. While taro genetic diversity has been documented at the country and regional levels in Asia and the Pacific, few reports are available from Americas and Africa where it has been introduced through human migrations. We used eleven microsatellite markers to investigate the diversity and diversification of taro accessions from nineteen countries in Asia, the...

Data from: How persistent are the impacts of logging roads on Central African forest vegetation?

Fritz Kleinschroth, John R. Healey, Plinio Sist, Frédéric Mortier & Sylvie Gourlet-Fleury
1. Logging roads can trigger tropical forest degradation by reducing the integrity of the ecosystem and providing access for encroachment. Therefore, road-management is crucial in reconciling selective logging and biodiversity conservation. Most logging roads are abandoned after timber harvesting, however little is known about their long-term impacts on forest vegetation and accessibility, especially in Central Africa. 2. In 11 logging concessions in the Congo Basin we field-sampled a chronosequence of roads that, judged by satellite...

Data from: The determinants of tropical forest deciduousness: disentangling the effects of rainfall and geology in central Africa

Dakis-Yaoba Ouédraogo, Adeline Fayolle, Sylvie Gourlet-Fleury, Frédéric Mortier, Vincent Freycon, Nicolas Fauvet, Suzanne Rabaud, Guillaume Cornu, Fabrice Bénédet, Jean-François Gillet, Richard Oslisly, Jean-Louis Doucet, Philippe Lejeune & Charly Favier
Understanding the environmental determinants of forests deciduousness i.e. proportion of deciduous trees in a forest stand, is of great importance when predicting the impact of ongoing global climate change on forests. In this study, we examine (i) how forest deciduousness varies in relation to rainfall and geology, and (ii) whether the influence of geology on deciduousness could be related to differences in soil fertility and water content between geological substrates. The study was conducted in...

Data from: Tropical rainforests that persisted: inferences from the Quaternary demographic history of eight tree species in the Guiana shield

Stéphanie Barthe, Giorgio Binelli, Bruno Hérault, Caroline Scotti-Saintagne, Daniel Sabatier & Ivan Scotti
How Quaternary climatic and geological disturbances influenced the composition of Neotropical forests is hotly debated. Rainfall and temperature changes during and/or immediately after the last glacial maximum (LGM) are thought to have strongly affected the geographical distribution and local abundance of tree species. The paucity of the fossil records in Neotropical forests prevents a direct reconstruction of such processes. To describe community-level historical trends in forest composition, we turned therefore to inferential methods based on...

Data from: Extra molting and selection on nymphal growth in the desert locust

Benjamin Pélissié, Cyril Piou, Hélène Jourdan-Pineau, Christine Pagès, Laurence Blondin & Marie-Pierre Chapuis
In insects, extra-molting has been viewed as a compensatory mechanism for nymphal growth that contributes to optimize body weight for successful reproduction. However, little is known on the capacity of extra-molting to evolve in natural populations, which limits our understanding of how selection acts on nymphal growth. We used a multi-generational pedigree, individual monitoring and quantitative genetics models to investigate the evolution of extra-molting and its impact on nymphal growth in a solitarious population of...

Data from: Importance of deep water uptake in tropical eucalypt forest

Mathias Christina, Yann Nouvellon, Jean-Paul Laclau, Jose L. Stape, Jean-Pierre Bouillet, George R. Lambais & Guerric Le Maire
Climate models predict that the frequency, intensity and duration of drought events will increase in tropical regions. Although water withdrawal from deep soil layers is generally considered to be an efficient adaptation to drought, there is little information on the role played by deep roots in tropical forests. Tropical Eucalyptus plantations managed in short rotation cycles are simple forest ecosystems that may provide an insight into the water use by trees in tropical forests. The...
