Data from: The interplay among intraspecific leaf trait variation, niche breadth and species abundance along light and soil nutrient gradients

Alex Fajardo & Andrew Siefert
It is assumed that widespread, generalist species have high phenotypic variation, but we know little about how intraspecific trait variation (ITV) relates to species abundance and niche breadth. In the temperate rainforest of southern Chile, we hypothesized that species with wide niche breadth would exhibit 1) high among-plot ITV, 2) a strong relationship between trait values and the environment, and 3) a close fit between traits and local environment trait optima. We measured leaf functional...

Data from: Local coastal configuration rather than latitudinal gradient shape clonal diversity and genetic structure of Phymatolithon calcareum maerl beds in North European Atlantic

Cristina Pardo, Marie-Laure Guillemin, Viviana Peña, Ignacio Bárbara, Myriam Valero & Rodolfo Barreiro
Maerl beds are one of the world’s key coastal ecosystems and are threatened by human activities and global change. In this study, the genetic diversity and structure of one of the major European maerl-forming species, Phymatolithon calcareum, was studied using eight microsatellite markers. Two sampling scales (global: North East Atlantic and regional: Galicia) were investigated and fifteen maerl beds from Atlantic Europe were sampled. At the regional-scale the location of sites outside and within four...

Data from: Comparative phylogeography of three host sea anemones in the Indo-Pacific

Aim The mutualistic relationship between anemones and anemonefishes is one of the most iconic examples of symbiosis. However, while anemonefishes have been extensively studied in terms of genetic connectivity, such information is lacking entirely for host sea anemones. Here, we provide the first information on the broad-scale population structure and phylogeographic patterns of three species of host sea anemone, Heteractis magnifica, Stichodactyla mertensii, and Entacmaea quadricolor. We evaluate if there is concordance in genetic structure...

Data from: A late Pleistocene human footprint from the Pilauco archaeological site, Northern Patagonia, Chile

Karen Moreno, Juan Enrique Bostelmann, Cintia Macías, Ximena Navarro-Harris, Ricardo De Pol-Holz & Mario Pino
The present study describes the discovery of a singular sedimentary structure corresponding to an ichnite that was excavated at the paleo-archaeological site Pilauco (Osorno, Chile). The trace fossil is associated with megafauna bones, plant material and unifacial lithic tools. Here we present a detailed analysis of the Pilauco ichnite and associated sedimentary structures, as well as new radiocarbon data. The ichnological analysis confidently assigns the trace to the ichnospecies Hominipes modernus—a hominoid footprint usually related...

Data from: Assessing the effects of human activities on the foraging opportunities of migratory shorebirds in Austral high-latitude bays

Juan G. Navedo, Claudio Verdugo, Ignacio Rodríguez-Jorquera, Jose M. Abad-Gómez, Cristián G. Suazo, Luis E. Castañeda, Valeria Araya, Jorge Ruiz & Jorge S. Gutiérrez
Human presence at intertidal areas could impact coastal biodiversity, including migratory waterbird species and the ecosystem services they provide. Assessing this impact is therefore essential to develop management measures compatible with migratory processes and associated biodiversity. Here, we assess the effects of human presence on the foraging opportunities of Hudsonian godwits (Limosa haemastica, a trans-hemispheric migratory shorebird) during their non-breeding season on Chiloé Island, southern Chile. We compared bird density and time spent foraging in...

Data from: The Magellanic Province and its fish fauna (South America): several provinces or one?

Ezequiel Mabragaña, Germán Pequeño, María Cousseau, Luis Lucifora, Patricia Martinez & Analía Giussi
Aim: We assessed the validity of the division of the Magellanic Province into the four provinces as proposed by Briggs and Bowen (2012): Southern Chile, Tierra del Fuego, Southern Argentina and Falkland (Malvinas) Islands. We aimed to 1) present an up to date list of the fishes from the region known as “Magellanic Province”, 2) analyze the specific richness of fishes in the Atlantic and Pacific sectors and their degree of endemism, 3) evaluate statistically...
