Habitat type drives the distribution of non-indigenous species in fouling communities regardless of associated maritime traffic

Jean-Charles Leclerc, Frédérique Viard, Elizabeth González Sepúlveda, Christian Díaz, José Neira Hinojosa, Karla Pérez Araneda, Francisco Silva & Antonio Brante
Aim: Biological invasions and changes in land and sea use are amongst the five major causes of global biodiversity decline. Shipping and ocean sprawl (multiplication of artificial structures at the expense of natural habitats) are considered as the major forces responsible for marine invasions and biotic homogenization. And yet, there is little evidence of their interplay at multiple spatial scales. Here, we aimed to examine this interaction and the extent to which the type of...

Data from: Zoogeographic patterns of pelagic oceanic cephalopods along the eastern Pacific Ocean

Christian M. Ibañez, Heather E. Braid, Sergio A. Carrasco, David A. Lopez-Cordova, Gabriela Torretti & Patricio A. Camus
Aim: To analyse the diversity and distribution of oceanic pelagic cephalopods along the Eastern Pacific Ocean, assessing the existence of biogeographic structuring, and the role of physical variables in generating geographical patterns. We hypothesized that the control by environmental factors, and the effect of geometric constraints, determine the range size and limits of distribution of oceanic cephalopods along the eastern Pacific Ocean, generating a latitudinal gradient in species richness. Location: Eastern Pacific Ocean (60°N –...

Files for phylogenetics, structure, and migration rate analyses for the bivalve Aequiyoldia eightsii

Carlos P. Muñoz-Ramírez, Chester Sands, David Barnes, James Scourse, Alejandro Roman-Gonzalez, Simon Morley, Leyla Cardenas, Antonio Brante & Michael Meredith
The Antarctic Circumpolar Current (ACC) dominates the open-ocean circulation of the Southern Ocean, and both isolates and connects the Southern Ocean biodiversity. However, the impact on biological processes of other Southern Ocean currents is less clear. Adjacent to the West Antarctic Peninsula (WAP), the ACC flows offshore in a northeastward direction, whereas the Antarctic Peninsula Coastal Current (APCC) follows a complex circulation pattern along the coast, with topographically-influenced deflections depending on the area. Using genomic...

Spatial dissimilarity of zooplankton and hydrodynamic conditions in a Patagonian channel used intensely by aquaculture: the influence of a geomorphological constriction

Eduardo Hernández-Miranda, Ignacio Betancourt, Marcus Sobarzo, Odette Vergara, Claudio Iturra & Renato A. Quiñones
Abstract Background Marine aquaculture is a very important economic and food production activity in Patagonian channels. The biophysical mechanisms through which farms interact with surrounding areas is poorly understood. A better understanding of the relationship between zooplankton distribution, hydrodynamics and aquaculture farms in Patagonian channels can contribute to the environmental sustainability of this activity. Methods The study was conducted in winter in the Caucahué Channel (Chiloé Island, southern Chile), which is composed of two asymmetric...

Historical allopatry and secondary contact or primary intergradation in the Puerto Rican Crested Anole, Anolis cristatellus, on Vieques Island

Liam J Revell, R. Graham Reynolds & Quynh N. Quach
Recent work revealed surprisingly deep mitochondrial genetic divergence in the lizard Anolis cristatellus among samples obtained from the small Caribbean island of Vieques. We sought to determine whether this had resulted from natural or anthropogenic causes, and (if the former), whether divergence occurred in a biogeographic context of allopatry followed by secondary contact, or via isolation-by-distance across the species’ historical range. We first estimated a mitochondrial gene tree for 379 samples and then genotyped 3,407...

Greater functional similarity in mobile compared to sessile assemblages colonizing artificial coastal habitats

Jean-Charles Leclerc, Naily Nashira Figueroa, Antonio Brante & Frédérique Viard
Among anthropogenic habitats built in the marine environment, floating and non-floating structures can be colonized by distinct assemblages. However, there is little knowledge whether these differences are also reflected in the functional structure. This study compared the functional diversity of sessile and mobile invertebrate assemblages that settle over 3 months on floating vs. non-floating artificial habitats, in two Chilean ports. Using morphological, trophic, behavioral, and life history traits, we found differences between mobile and sessile...

Leaf resistance traits influence endophytic fungi colonization and community composition in a South American temperate rainforest

Marcia González-Teuber, Guevara-Araya María José, Vilo Claudia, Salgado-Luarte Cristian & Gianoli Ernesto
Despite the ubiquitous presence of fungal endophytes in woody plants, mechanisms underlying variation in foliar fungal endophyte communities are poorly understood. Given that endophytes in woody plants are predominantly horizontally transmitted, fungal endophyte colonization of foliar tissues is likely to be influenced by plant resistance traits. Here, we evaluated the association between leaf resistance traits and colonization and community composition of horizontally transmitted endophytes (HTE) in ten dominant trees species in a temperate rainforest in...

After a catastrophe, a little bit of sex is better than nothing: genetic consequences of a major earthquake on asexual and sexual populations

Ronan Becheler, Marie-Laure Guillemin, Solenn Stoeckel, Stéphane Mauger, Alice Saunier, Antonio Brante, Destombe Christophe & Valero Myriam
Catastrophic events can have profound effects on the demography of a population and consequently, on genetic diversity. The dynamics of post-catastrophic recovery as well as the role of sexual versus asexual reproduction in buffering the effects of massive perturbations remain poorly understood, in part because the opportunity to document genetic diversity before and after such events is rare. Six natural (purely sexual) and seven cultivated (mainly clonal due to farming practices) populations of the red...
