Understanding larval connectivity patterns in exploited fishes is a fundamental prerequisite for developing effective management strategies and assessing the vulnerability of a fishery to recruitment overfishing and localised extinction. To date however, researchers have not considered how regional variations in fishing pressure also influence recruitment. We used genetic parentage analyses and modelling to infer the dispersal patterns of bumphead parrotfish (Bolbometopon muricatum) larvae in the Kia fishing grounds, Isabel Province, Solomon Islands. We then extrapolated...
Supplementary material: Ultraconserved elements improve the resolution of difficult nodes within the rapid radiation of neotropical sigmodontine rodents (Cricetidae: Sigmodontinae)Andrés Parada, Guillermo D'Elía & John Hanson
Sigmodontine rodents (Cricetidae, Sigmodontinae) represent the second largest muroid subfamily and the most species-rich group of New World mammals, encompassing above 410 living species and ca. 87 genera. Even with advances on the clarification of sigmodontine phylogenetic relationships that have been made recently, the phylogenetic relationships among the 11 main group of genera (i.e., tribes) remain poorly resolved, in particular among those forming the large clade Oryzomyalia. This pattern has been interpreted as consequence of...

Monitoring plans using environmental DNA have the potential to offer a standardized and cost-efficient method to survey biodiversity in aquatic ecosystems. Among these ecosystems, coastal wetlands are key elements that serve as transition zones between marine and freshwater ecosystems and are today the target of many conservation and restoration efforts. In this sense, eDNA monitoring could provide a rapid and efficient tool for studying and generating baseline biodiversity information to guide coastal wetland management programs....
Pinpointing genetic breaks in the southeastern Pacific: phylogeography and genetic structure of Pyura chilensis, a commercially important tunicateSuany Quesada-Calderon, Emily C. Giles, Sarai Morales-González & Pablo Saenz-Agudelo
Aim: Accurate characterization of evolutionary units (species or populations) underlies all ecological and evolutionary studies and is crucial to conservation planning. Seascapes have long been thought to be highly permeable to gene flow, yet over the last decade building evidence has shown that barriers to gene flow in marine environments are much more common than previously thought. Here, we precisely characterize barriers to gene flow in the tunicate Pyura chilensis across 26° of latitude in...
1. Predators can exert nonconsumptive effects (NCEs) on prey, which often take place through prey behavioural adjustments to minimize predation risk. As NCEs are widespread in nature, interest is growing to determine whether NCEs on a prey species can indirectly influence several other species simultaneously, thus leading to changes in community structure. 2. In this study, we investigate whether a predator can exert NCEs on a foundation species and indirectly affect community structure. 3. Through...
Semi-intensive Shrimp-Farms as Experimental Arenas for the Study of Predation Risk from Falcons to ShorebirdsJuan G. Navedo
Varying environmental conditions and energetic demands can affect habitat use by predators and their prey. Anthropogenic habitats may provide an opportunity to document both predation events and foraging activity by prey, and therefore enable an empirical evaluation how prey cope with trade-offs between starvation and predation risk in environments of variable foraging opportunities and predation danger. Here we use seven years of observational data of peregrine falcons Falco peregrinus and shorebirds at a semi-intensive shrimp-farm...
Cetaceans are the longest-living species of mammals and the largest in the history of the planet. They have developed mechanisms against diseases such cancer, although the underlying molecular bases of these remain unknown. The goal of this study was to investigate the role of natural selection in the evolution of 1077 tumour suppressor genes (TSGs) in cetaceans. We used a comparative genomic approach to analyse two sources of molecular variation in the form of dN/dS...
