Dispersal distances of radio-tracked cane toads in French Guiana

Richard Shine, Jayna DeVore & Simon Ducatez
Like most invasive species, cane toads have attracted less research in their native range than in invaded areas. We radio-tracked 34 free-ranging toads in French Guiana, a source region for most invasive populations, across two coastal and two rainforest sites. Coastal toads generally sheltered in pools of fresh or brackish water but nocturnally foraged on beaches, whereas rainforest toads sheltered in forested habitats, moving into open areas at night. Over five days of monitoring, native...

Agroecosystem diversification with legumes or non-legumes improves differently soil fertility according to soil type

Plant diversification through crop rotation or agroforestry is a promising way to improve sustainability of agroecosystems. Nonetheless, criteria to select the most suitable plant communities for agroecosystems diversification facing contrasting environmental constraints need to be refined. Here, we compared the impacts of 24 different plant communities on soil fertility across six tropical agroecosystems: either on highly weathered Ferralsols, with strong P limitation, or on partially weathered soils derived from volcanic material, with major N limitation....

Global maps of current (1979-2013) and future (2061-2080) habitat suitability probability for 1,485 European endemic plant species

Aims: The rapid increase in the number of species that have naturalized beyond their native range is among the most apparent features of the Anthropocene. How alien species will respond to other processes of future global changes is an emerging concern and remains largely misunderstood. We therefore ask whether naturalized species will respond to climate and land-use change differently than those species not yet naturalized anywhere in the world. Location: Global Methods: We investigated future...

Tree communities and soil properties influence fungal community assembly in neotropical forests

Heidy Schimann, Jason Vleminckx, Christopher Baraloto, Julien Engel, Gaelle Jaouen, Eliane Louisanna, Sophie Manzi, Audrey Sagne & Mélanie Roy
The influence exerted by tree communities, topography and soil chemistry on the assembly of macrofungal communities remains poorly understood, especially in highly diverse tropical forests. Here, we used a large dataset that combines inventories of macrofungal Basidiomycetes fruiting bodies, tree species composition and measurements for 16 soil physico-chemical parameters, collected in 34 plots located in four sites of lowland rainforests in French Guiana. Plots were established on three different topographical conditions: hilltop, slope and seasonally...

Pleistocene climatic fluctuations promoted alternative evolutionary histories in Phytelephas aequatorialis, an endemic palm from western Ecuador

Sebastián Escobar, Andrew J Helmstetter, Scott Jarvie, Rommel Montúfar, Henrik Balslev & Thomas LP Couvreur
Aim: Pleistocene (2.58 Ma – 11.7 ka) climatic fluctuations have shaped intraspecific genetic patterns worldwide; however, their manifestation in many regions remains unknown. In order to determine the impact of Pleistocene climatic fluctuations on the tropical rain forests of western Ecuador, we explored the evolutionary history of the endemic palm Phytelephas aequatorialis. Location: Western Ecuador, northwestern South America. Taxon: Phytelephas aequatorialis (Arecaceae). Methods: 176 nuclear genes were sequenced in 91 individuals for phylogenomic and population...

A “Dirty” Footprint: Soil macrofauna biodiversity and fertility in Amazonian Dark Earths and adjacent soils

Segalla, Thibaud Decaëns, Herlon S. Nadolny, Clara P. Peña‐Venegas, Cláudia M. B. F. Maia, Amarildo Pasini … & George G. Brown
Amazonian rainforests once thought to hold an innate pristine wilderness, are increasingly known to have been densely inhabited by populations showing a diverse and complex cultural background prior to European arrival. To what extent these societies impacted their landscape is unclear. Amazonian Dark Earths (ADEs) are fertile soils found throughout the Amazon Basin, created by pre-Columbian societies as a result of more sedentary habits. Much is known of the chemistry of these soils, yet their...

Monitoring vertebrate biodiversity of a protected coastal wetland using eDNA metabarcoding

Pablo Saenz-Agudelo, Erwan Delrieu-Trottin, Joseph D. DiBattista, Diego Martinez, Sarai Morales-Gonzáles, Felipe Pontigo, Paula Ramirez, Andrea Silva, Mauricio Soto & Cristian Correa
Monitoring plans using environmental DNA have the potential to offer a standardized and cost-efficient method to survey biodiversity in aquatic ecosystems. Among these ecosystems, coastal wetlands are key elements that serve as transition zones between marine and freshwater ecosystems and are today the target of many conservation and restoration efforts. In this sense, eDNA monitoring could provide a rapid and efficient tool for studying and generating baseline biodiversity information to guide coastal wetland management programs....

Mitogenomics dataset for the Rasborinae of Sundaland

Nicolas Hubert
Aim: Eustasy has long been put forward to explain the colonization of Southeast Asian islands by freshwater aquatic organisms. We examined the relative impact of Sundaland geology since the Oligocene and of Pleistocene Eustatic Fluctuations on the mitochondrial lineage diversification of a species-rich subfamily of Cypriniformes fishes widely distributed in Southeast Asia, the Rasborinae. We specifically tested if variations in the extent of exposed lands and island connectivity during Pleistocene eustasy (the Paleoriver hypothesis) induced...

Checklists of endemic tracheophytes and bryophytes to the French Overseas Territories

Simon Veron, Carlos Rodrigues-Vaz, Elise Lebreton, Claudine Ah-Peng, Vincent Boullet, Hervé Chevillotte, Stephan Robbert Gradstein, Joël Jérémie, Elisabeth Lavocat-Bernard, Marc Lebouvier, Jean-Yves Meyer, Jérôme Munzinger, Odile Poncy, Louis Thouvenot, Guillaume Viscardi, Guillaume Léotard, Olivier Gargominy, Sébastien Leblond, Marc Pignal, Germinal Rouhan, Sandrine Tercerie, Vanessa Invernon & Serge Muller
A broad range of climatic and biogeographical conditions are represented in the French Overseas Territories, from sub-polar to equatorial, resulting in a high diversity of endemic species. We mobilized data from herbaria, floras, checklists, literature, the expertise of botanists and plant ecologists to compile the most complete dataset on endemic vascular plants and bryophytes in the 15 French Overseas Territories. To date, 3748 spermatophytes (seed plants), 244 pteridophytes (ferns and lycophytes) and 448 bryophytes are...

Data from: The demographic history of micro-endemics: Have rare species always been rare?

Andrew Helmstetter
Extinction has increased as human activities impact ecosystems. Conservation assessments for the IUCN red list are a fundamental tool in aiding the prevention of further extinction, yet, relatively few species have been thoroughly assessed. To increase the efficiency of assessments, novel approaches are needed to highlight threatened species that are currently data deficient. Many Madagascan plant species currently have extremely narrow ranges, but this may not have always been the case. To assess this, we...
