The results of comparative song analyses between the ASSO and the Ecuadorian and Brazilian breeding populations and recordings from the Chilean, South African and Namibian migration routes revealed that individuals from at least three humpback whale breeding populations most likely migrate to shared feeding grounds in the ASSO. Humpback whales from different populations potentially mix at different times (i.e., years) at feeding hotspots of variable locations.

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...

Phylogenetic data for: High diversity of new and known Phytophthora species from phylogenetic Clade 10 in natural ecosystems of Asia, Europe and the Americas

Thomas Jung, Ivan Milenković, Tamara Corcobado, Tomáš Májek, Josef Janoušek, Tomáš Kudláček, Michal Tomšovský, Zoltán Nagy, Álvaro Durán, Marthin Tarigan, Eugenio Sanfuentes Von Stowasser, Raghuwinder Singh, Monique Ferreira, Joan Webber, Bruno Scanu, Nguyen Minh Chi, Pham Quang Thu, Muhammad Junaid, Ade Rosmana, Baharuddin Baharuddin, Tutik Kuswinanti, Nasri Nasri, Koji Kageyama, Ayaka Hieno, Hayato Masuya … & Marília Horta Jung
During extensive surveys of Phytophthora diversity, 14 new species were detected in natural ecosystems in Chile, Louisiana, Sweden, Ukraine, Vietnam and Indonesia. Multigene phylogeny based on the nuclear LSU, rpl10, ITS, ßtub, enl, hsp90, tef-1α, ras-ypt1 and tigA and the mitochondrial cox1, nadh1 and rps10 gene sequences demonstrated that they belong to phylogenetic Clade 10 which is structured into three subclades. Subclades 10a and 10b comprise soil- and waterborne species with nonpapillate sporangia and variable...

Data from: Phylogenomic analyses of echinoid diversification prompt a re-evaluation of their fossil record

Nicolás Mongiardino Koch, Jeffrey R Thompson, Avery S Hatch, Marina F McCowin, A Frances Armstrong, Simon E Coppard, Felipe Aguilera, Omri Bronstein, Andreas Kroh, Rich Mooi & Greg W Rouse
Echinoids are key components of modern marine ecosystems. Despite a remarkable fossil record, the emergence of their crown group is documented by few specimens of unclear affinities, rendering their early history uncertain. The origin of sand dollars, one of its most distinctive clades, is also unclear due to an unstable phylogenetic context. We employ eighteen novel genomes and transcriptomes to build a phylogenomic dataset with a near-complete sampling of major lineages. With it, we revise...

A song of wind and ice: increased frequency of marine cold-spells in southwestern Patagonia and their possible effects on giant kelp forests

Alejandra Mora-Soto, Catalina Aguirre, Jose Luis Iriarte, Mauricio Palacios, Erasmo C. Macaya & Marc Macias-Fauria
In contrast to other coastal regions of the world, the giant kelp (Macrocystis pyrifera) ecosystem in southwestern Patagonia has been persistent in area and associated biodiversity in the last decades. In this ecoregion, Sea Surface Temperature (SST) records have consistently remained below the upper thermal threshold for kelp survival, however no studies have analysed the spatiotemporal variability of SSTs and their anomalies across the geographical diversity of the southwestern Patagonian coastline. We explored the geographical...

Trait functional diversity explains mixture effects on litter decomposition at the arid end of a climate gradient

Rafaella Canessa, Liesbeth Van Den Brink, Monica Berdugo, Stephan Hattenschwiler, Rodrigo Rios, Alfredo Saldana, Katja Tielboerger & Maaike Bader
Litter decomposition is controlled by climate, litter quality and decomposer communities. Because the decomposition of specific litter types is also influenced by the properties of adjacent types, mixing litter types may result in non-additive effects on overall decomposition rates. The strength of these effects seems to depend on the litter functional diversity. However, it is unclear which functional traits or combination of traits explain litter mixture effects and if these depend on the range of...
