Datafile - In situ adaptation and ecological release facilitate the occupied niche expansion of an invasive Madagascan day gecko in Florida

Thomas Fieldsend, Nicolas Dubos, Kenneth Krysko, Christopher Raxworthy & Sparkle Malone
Aim To investigate whether the frequently advocated climate-matching species distribution modelling approach could predict the well-characterized colonization of Florida by the Madagascar giant day gecko Phelsuma grandis. Location Madagascar and Florida, USA. Methods To determine the climatic conditions associated with the native range of P. grandis, we used native-range presence-only records and Bioclim climatic data to build a Maxent species distribution model and projected the climatic thresholds of the native range onto Florida. We then...

The annual productivity metrics were derived from the CARBONO Project litterfall and tree-growth data that were provided and documented in prior Dryad data depositions. A third file in this deposition provides the daily data underlying the...

Oceanographic features and limited dispersal shape the population genetic structure of the vase sponge Ircinia campana in the Greater Caribbean

Sarah Griffiths, Mark Butler, Donald Behringer, Thierry Pérez & Richard Preziosi
Understanding population genetic structure can help us to infer dispersal patterns, predict population resilience and design effective management strategies. For sessile species with limited dispersal, this is especially pertinent because genetic diversity and connectivity are key aspects of their resilience to environmental stressors. Here, we describe the population structure of Ircinia campana, a common Caribbean sponge subject to mass mortalities and disease. Microsatellites were used to genotype 440 individuals from 19 sites throughout the Greater...

Habitat structure mediates vulnerability to climate change through its effects on thermoregulatory behavior

Lauren Neel, Michael Logan, Daniel Nicholson, Christina Miller, Albert Chung, Inbar Maayan, Zach Degon, Madeline DuBois, John David Curlis, Q Taylor, Kaitlin Keegan, Owen McMillan, Jonathan Losos & Christian Cox
Tropical ectotherms are thought to be especially vulnerable to climate change because they are thermal specialists, having evolved in aseasonal thermal environments. However, even within the tropics, habitat structure can influence opportunities for behavioral thermoregulation. Open (and edge) habitats likely promote more effective thermoregulation due to the high spatial heterogeneity of the thermal landscape, while forests are thermally homogenous and may constrain opportunities for behavioral buffering of environmental temperatures. Nevertheless, the ways in which behavior...

E-scape: consumer-specific landscapes of energetic resources derived from stable isotope analysis and remote sensing

W. Ryan James, Rolando Santos, Jennifer Rehage, Jennifer Doerr & James Nelson
Energetic resources and habitat distribution are inherently linked. Energetic resource availability is a major driver of the distribution of consumers, but estimating how much specific habitats contribute to the energetic resource needs of a consumer can be problematic. We present a new approach that combines remote sensing information and stable isotope ecology to produce maps of energetic resources (E-scapes). E-scapes project species-specific resource use information onto the landscape to classify areas based on energetic importance....

Whence came these plants most foul? Phylogenomics and biogeography of Lowiaceae (Zingiberales)

Matti Niissalo, Elliot Gardner, Gillian Khew, Otakar Šída, Axel Poulsen & Jana Leong-Škornicková
Lowiaceae (order Zingiberales) is a small family of forest herbs in Southeast Asia. All species belong to the genus Orchidantha. They are known for possessing orchid-like flowers that are smelly, apparently mimicking dead animals, feces, or mushrooms. Little is known of the biogeographic patterns or character evolution of the family. We sampled the family extensively, including many recently discovered species, and reconstructed the phylogeny of the family using HybSeq with Lowiaceae-specific RNA baits. Our phylogenetic...

Genetic mechanisms and correlational selection structure trait variation in a coral snake mimic

John David Curlis, Alison Davis Rabosky, Iris Holmes, Timothy Renney & Christian Cox
Covariation among traits shapes both phenotypic evolution and ecological interactions across space and time. However, rampant geographic variation in the strength and direction of such correlations can be particularly difficult to explain through generalized mechanisms. By integrating population genomics, surveys of natural history collections, and spatially-explicit analyses, we tested multiple drivers of trait correlations in a coral snake mimic that exhibits remarkable polymorphism in mimetic and non-mimetic color traits. We found that although such traits...

Endothermy makes fishes faster but does not expand their thermal niche

Lucy Harding, Andrew Jackson, Adam Barnett, Ian Donohue, Lewis Halsey, Charlie Huveneers, Carl Meyer, Yannis Papastamatiou, Jayson Semmens, Erin Spencer, Yuuki Watanabe & Nicholas Payne
1. Regional endothermy has evolved several times in marine fishes, and two competing hypotheses are generally proposed to explain the evolutionary drivers behind this trait: thermal niche expansion and elevated cruising speeds. Evidence to support either hypothesis is equivocal, and the ecological advantages conferred by endothermy in fishes remain debated. 2. By compiling published biologging data and collecting precise speed measurements from free-swimming fishes in the wild, we directly test whether endothermic fishes encounter broader...

Supporting Data To: Shark tooth collagen stable isotopes (δ15N and δ13C) as ecological proxies

Oliver Shipley, Gregory Henkes, James Gelsleichter, Clark Morgan, Eric Schneider, Brendan Talwar & Michael Frisk
The isotopic composition of tooth-bound collagen has long been used to reconstruct dietary patterns of animals in extant and paleoecological systems. For sharks that replace teeth rapidly in a conveyor-like system, stable isotopes of tooth collagen (δ13Ctooth & δ15Ntooth) are poorly understood and lacking in ecological context relative to other non-lethally sampled tissues. This tissue holds promise, because shark jaws may preserve isotopic chronologies from which to infer individual-level ecological patterns across a range of...

Sharks surf the slope: current updrafts reduce energy expenditure for aggregating marine predators

Yannis Papastamatiou
An animal’s energy landscape considers the power requirements associated with residing or moving through habitats. Within marine environments, these landscapes can be dynamic, as water currents will influence animal power requirements and can change rapidly over diel and tidal cycles. In channels and along slopes with strong currents, updraft zones may reduce energy expenditure of negatively buoyant fishes that are also obligate swimmers. Despite marine predators often residing within high-current area, no study has investigated...

Detectability and impact of repetitive surveys on threatened West African crocodylians: Data M1

Michel N'Dede Ahizi, Christine Yaoua Kouman, Allassane Ouattara, N’Dri Pascal Kouame, Azani Dede, Emilie Fairet & Matthew H. Shirley
West African crocodylians are among the most threatened and least studied crocodylian species globally. Assessing population status and establishing a basis for population monitoring is the highest priority action for this region. Monitoring of crocodiles is influenced by many factors that affect detectability, including environmental variables and individual or population-level wariness. We investigated how these factors affect detectability and counts of the Critically Endangered Mecistops cataphractus and the newly recognized Crocodylus suchus. We implemented 195...

Patch size drives colonization by aquatic insects, with minor priority effects of a cohabitant

Matthew Pintar, Reed C. Scott & William J. Resetarits
Patch size is one of the most important factors affecting the distribution and abundance of species, and recent research has shown that patch size is an important niche dimension affecting community structure in aquatic insects. Building on this result, we examined the impact of patch size in conjunction with presence of larval anurans on colonization by aquatic insects. Hyla chrysoscelis (Cope’s gray treefrog) larvae are abundant and early colonists in fishless lentic habitats, and these...

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...

Data from: Biogeographic history and habitat specialisation shape floristic and phylogenetic composition across Amazonian forests

Christopher Baraloto, Jason Vleminckx, Julien Engel, Pascal Petronelli, Nállarett Dávila, Marcos Ríos, Elvis Harry Valderrama Sandoval, Italo Mesones, Juan Ernesto Guevara Andino, Claire Fortunel, Elodie Allie, C. E. Timothy Paine, Aurélie Dourdain, Jean-Yves Goret, Oscar J. Valverde-Barrantes, Freddie Draper & Paul V. A. Fine
A major challenge remains to understand the relative contributions of history, dispersal and environmental filtering to the assembly of hyperdiverse communities across spatial scales. Here, we examine the extent to which biogeographical history and habitat specialization have generated turnover among and within lineages of Amazonian trees across broad geographic and environmental gradients. We replicated standardised tree inventories in 102 0.1-ha plots located in two distant regions - the western Amazon and the eastern Guiana shield....
