Data from: Biodiversity assessment of tropical shelf eukaryotic communities via pelagic eDNA metabarcoding

Owen S. Wangensteen, Judith Bakker, Stefano Mariani, Charles Baillie, Dayne Buddo, Demian D. Chapman, Austin J. Gallagher, Tristan L. Guttridge & Heidi Hertler
Our understanding of marine communities and their functions in an ecosystem relies on the ability to detect and monitor species distributions and abundances. Currently, the use of environmental DNA (eDNA) metabarcoding is increasingly being applied for the rapid assessment and monitoring of aquatic species. Most eDNA metabarcoding studies have either focused on the simultaneous identification of a few specific taxa/groups or have been limited in geographical scope. Here we employed eDNA metabarcoding to compare beta...

Data from: Population structure, connectivity and demographic history of an apex marine predator, the bull shark Carcharhinus leucas

Agathe Pirog, Virginie Ravigné, Michaël Fontaine, Adrien Rieux, Aude Gilabert, Geremy Cliff, Eric Clua, Ryan Daly, Michael Heithaus, Jeremy Kiszka, Philip Matich, John Nevill, Amy Smoothey, Andrew Temple, Per Berggren, Sebastien Jaquemet & Hélène Magalon
Knowledge of population structure, connectivity and effective population size remains limited for many marine apex predators, including the bull shark Carcharhinus leucas. This large-bodied coastal shark is distributed worldwide in warm temperate and tropical waters, and uses estuaries and rivers as nurseries. As an apex predator, the bull shark likely plays a vital ecological role within marine food webs, but is at risk due to inshore habitat degradation and various fishing pressures. We investigated the...

Data from: Indirect legacy effects of an extreme climactic event on a marine megafaunal community

Robert Nowicki, Michael Heithaus, Jordan Thomson, Derek Burkholder, Kirk Gastrich & Aaron Wirsing
While extreme climactic events (ECEs) are predicted to become more frequent, reliably predicting their impacts on consumers remains challenging– particularly for large consumers in marine environments. Many studies that do evaluate ECE effects focus primarily on direct effects, though indirect effects can be equally or more important. Here, we investigate the indirect impacts of the 2011 “Ningaloo Niño” marine heatwave ECE on a diverse megafauna community in Shark Bay, Western Australia. We use an 18...

Evaluating the effects of large marine predators on mobile prey behavior across subtropical reef ecosystems

Lindsay Phenix, Dana Tricarico, Mark Bond, Simon Brandl & Austin Gallagher
The indirect effect of predators on prey behavior, recruitment, and spatial relationships continues to attract considerable attention. However, top predators like sharks or large, mobile teleosts, which can have substantial top-down effects in ecosystems, are often difficult to study due to their large size and mobility. This has created a knowledge gap in understanding how they affect their prey through non-consumptive effects. Here we investigated how different functional groups of predators affected potential prey fish...

La mirada antropológica de Nicolás Guillén Landrián: subalternidad y diferencia en sus primeros documentales

Santiago Juan-Navarro
Este artigo aborda os primeiros documentários de Nicolás Guillén Landrián, de meados dos anos 1960 e interpretados como expressão do espírito de resistência e da pluralidade de alguns grupos marginais (a comunidade afro-cubana de Havana e as colónias de camponeses na zona leste da ilha) numa época em que os marcadores da diferença eram julgados uma ameaça para o discurso normalizador do castrismo. Nessas curtas-metragens, Guillén Landrián introduziu um olhar antropológico focado naqueles sujeitos sociais...

Data from: A phylogenomic framework, evolutionary timeline and genomic resources for comparative studies of decapod crustaceans

Joanna M. Wolfe, Jesse W. Breinholt, Keith A. Crandall, Alan R. Lemmon, Emily Moriarty Lemmon, Laura E. Timm, Mark E. Siddall & Heather D. Bracken-Grissom
Comprising over 15 000 living species, decapods (crabs, shrimp and lobsters) are the most instantly recognizable crustaceans, representing a considerable global food source. Although decapod systematics have received much study, limitations of morphological and Sanger sequence data have yet to produce a consensus for higher-level relationships. Here, we introduce a new anchored hybrid enrichment kit for decapod phylogenetics designed from genomic and transcriptomic sequences that we used to capture new high-throughput sequence data from 94...

Data from: Nonlinearity of root trait relationships and the root economics spectrum

Deliang Kong, Junjian Wang, Huifang Wu, Oscar J. Valverde-Barrantes, Ruili Wang, Hui Zeng, Paul Kardol, Haiyan Zhang & Yulong Feng
The root economics spectrum (RES), a common hypothesis postulating a tradeoff between resource acquisition and conservation traits, is being challenged by conflicting relationships between root diameter, tissue density (RTD) and root nitrogen concentration (RN). Here, we analyze a global trait dataset of absorptive roots for over 800 plant species. For woody species (but not for non-woody species), we find nonlinear relationships between root diameter and RTD and RN, which stem from the allometric relationship between...
