Linking variation in planktonic primary production to coral reef fish growth and condition

Ronan Roche
Within low nutrient tropical oceans, islands and atolls with higher primary production support higher reef fish biomass and reef organism abundance. External energy subsidies can be delivered onto reefs via a range of physical mechanisms. However, the influence of spatial variation in primary production on reef fish growth and condition is largely unknown. It is not yet clear how variability in food delivery onto a reef interacts with reef depth and slope, and affects reef...

Hurricane disturbance accelerated the thermophilization of a Jamaican montane forest

Edmund V. J. Tanner, Peter Bellingham, John Healey & Kenneth Feeley
Thermophilization – changes in community composition towards greater relative abundances of species associated with warmer environments – has been described for plants and animals in many locations around the world. Disturbances of various kinds have increased rates of thermophilization in temperate sites, and this has been proposed, but not demonstrated, for some tropical environments. In this study, we tested whether disturbance by a Category four hurricane in 1988 (Hurricane Gilbert) increased thermophilization in a Jamaican...

Hybridisation and chloroplast capture between ancient Themeda triandra ecotypes in Australia

Luke Dunning, Jill Olofsson, Alexander Papadopulos, Samuel Hibdige, Oriane Hidalgo, Ilia Leitch, Paulo Baleeiro, Sinethemba Ntshangase, Nigel Barker & Richard Jobson
Ecotypes are distinct populations within a species that are adapted to specific environmental conditions. Understanding how these ecotypes become established, and how they interact when reunited, is fundamental to elucidating how ecological adaptations are maintained. This study focuses on Themeda triandra, a dominant grassland species across Asia, Africa and Australia. It is the most widespread plant in Australia, where it has distinct ecotypes that are usually restricted to either wetter and cooler coastal regions or...

Data from: Genomic islands of speciation separate cichlid ecomorphs in an East African crater lake

Milan Malinsky, Richard J. Challis, Alexandra M. Tyers, Stephan Schiffels, Yohey Terai, Benjamin P. Ngatunga, Eric A. Miska, Richard Durbin, Martin J. Genner & George F. Turner
The genomic causes and effects of divergent ecological selection during speciation are still poorly understood. Here we report the discovery and detailed characterization of early-stage adaptive divergence of two cichlid fish ecomorphs in a small (700 meters in diameter) isolated crater lake in Tanzania. The ecomorphs differ in depth preference, male breeding color, body shape, diet, and trophic morphology. With whole-genome sequences of 146 fish, we identified 98 clearly demarcated genomic “islands” of high differentiation...

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 importance of being genomic: non-coding and coding sequences suggest different models of toxin multi-gene family evolution

Anita Malhotra, Simon Creer, John B. Harris & Roger S. Thorpe
Studies of multi-gene protein families, including many toxins, are crucial for understanding the role of gene duplication in generating protein diversity in general. However, many evolutionary analyses of gene families are based on coding sequences, and do not take into account many potentially confounding evolutionary factors, such as recombination and convergence due to selection. We illustrate this using snake venom gene sequences from the Phospholipase A2 (PLA2) subfamily. Novel gene sequences from 20 species of...

Data from: Quantifying pursuit-diving seabirds' associations with fine-scale physical features in tidal stream environments

James J. Waggitt, Pierre W. Cazenave, Ricardo Torres, Benjamin J. Williamson & Beth E. Scott
The rapid increase in the number of tidal stream turbine arrays will create novel and unprecedented levels of anthropogenic activity within habitats characterized by horizontal current speeds exceeding 2 ms−1. However, the potential impacts on pursuit-diving seabirds exploiting these tidal stream environments remain largely unknown. Identifying similarities between the fine-scale physical features (100s of metres) suitable for array installations, and those associated with foraging pursuit-diving seabirds, could identify which species are most vulnerable to either...

Data from: The biogeography of the atlantic salmon (Salmo salar) gut microbiome

Martin S. Llewellyn, Philip McGinnity, Melanie Dionne, Justine Letourneau, Florian Thonier, Gary R. Carvalho, Simon Creer & Nicolas Derome
Although understood in many vertebrate systems, the natural diversity of host-associated microbiota has been little studied in teleosts. For migratory fishes, successful exploitation of multiple habitats may affect and be affected by the composition of the intestinal microbiome. We collected 96 Salmo salar from across the Atlantic encompassing both freshwater and marine phases. Dramatic differences between environmental and gut bacterial communities were observed. Furthermore, community composition was not significantly impacted by geography. Instead life-cycle stage...

Payne, Melita Peharda, Jakup Reinert … & Lilja Stefansdottir
Aim Previous analyses of marine fish species richness based on presence-absence data have shown changes with latitude and average species size, but little is known about the underlying processes. To elucidate these processes we use metabolic, neutral, and descriptive statistical models to analyse how richness responds to maximum species length, fish abundance, temperature, primary production, depth, latitude, and longitude, while accounting for differences in species catchability, sampling effort, and mesh size. Data Results from 53,382...

Mary K. Donovan, Alan M. Friedlander, Joey Lecky, Jean-Baptiste Jouffray, Gareth J. Williams, Lisa M. Wedding, Larry B. Crowder, Ashley L. Erickson, Nick A. J. Graham, Jamison M. Gove, Carrie V. Kappel, Kendra Karr, John N. Kittinger, Albert V. Norström, Magnus Nyström, Kirsten L. L. Oleson, Kostantinos A. Stamoulis, Crow White, Ivor D. Williams & Kimberly A. Selkoe
Coral reefs worldwide face an uncertain future with many reefs reported to transition from being dominated by corals to macroalgae. However, given the complexity and diversity of the ecosystem, research on how regimes vary spatially and temporally is needed. Reef regimes are most often characterised by their benthic components; however, complex dynamics are associated with losses and gains in both fish and benthic assemblages. To capture this complexity, we synthesised 3,345 surveys from Hawai‘i to...

Data from: Exploring preferences for variable delays over fixed delays to high-value food rewards as a model of food-seeking behaviours in humans

Laura-Jean G. Stokes, Anna Davies, Paul Lattimore, Catharine Winstanley & Robert D. Rogers
Foraging and operant models suggest that animals will tolerate uncertainty or risk to obtain food quickly. In modern food environments, sustained access to quick energy-dense foods can promote weight gain. Here, we used a discrete-choice procedure to examine peoples' decisions about when next to eat high-value, palatable food rewards, probabilistically delivered immediately or following longer delays. In Experiment 1, moderately hungry young females showed consistent preferences for a variable delay option that delivered food rewards...
