Scientists and managers rely on indicator taxa such as coral and macroalgal cover to evaluate the effects of human disturbance on coral reefs, often assuming a universally positive relationship between local human disturbance and macroalgae. Despite evidence that macroalgae respond to local stressors in diverse ways, there have been few efforts to evaluate relationships between specific macroalgae taxa and local human‐driven d...
Rank change and growth within social hierarchies of the orange clownfish, Amphiprion perculaNARA Subscribed
Social hierarchies within groups define the distribution of resources and provide benefits that support the collective group or favor dominant members. The progression of individuals through social hierarchies is a valuable characteristic for quantifying population dynamics. On coral reefs, some clownfish maintain size-based hierarchical communities where individuals queue through social ranks. The cost of waiting in a lower-r...
NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the NeotropicsNARA Subscribed
Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal specie...
When endemic coral‐reef fish species serve as models: endemic mimicry patterns in the Marquesas IslandsNARA Subscribed
This article documents several cases of widespread species, which usually mimic other widespread species throughout the Indo‐Pacific, using endemic Marquesan species as a model and displaying endemic mimicry patterns. This discovery adds a new line of evidence to the uniqueness of the Marquesas Islands, which not only host a high number of endemic reef‐fish species, but also endemic mimicry patterns.
Understanding the distribution of genetic diversity in the light of past demographic events linked with climatic shifts will help to forecast evolutionary trajectories of ecosystems within the current context of climate change. In this study, mitochondrial sequences and microsatellite loci were analysed using traditional population genetic approaches together with Bayesian dating and the more recent approximate Bayesian comput...

Population structure, spatial distribution and life‐history traits of blacktip reef sharks Carcharhinus melanopterusNARA Subscribed
During a survey of the population of blacktip reef shark Carcharhinus melanopterus in Moorea (French Polynesia) between 2007 and 2011, population structural characteristics were estimated from 268 individuals. Total length ( L T ) ranged from 48 to 139 cm and 48 to 157 cm for males and females, respectively, demonstrating that the average L T of females was larger than that of males. The C. melanopterus population at Moorea sh...
Fisheries replenishment of early life taxa: potential export of fish eggs and larvae from a temperate marine protected areaNARA Subscribed
An ichthyoplankton survey was conducted at the periphery of Cabrera National Park (Balearic Islands, Western Mediterranean Sea) in July 2004, using bongo nets, fixed nets and collection of oceanographic data. This work focused on analysing the distribution of eggs and larval stages of some fishery‐targeted taxa ( Coris julis, Epinephelus spp. , Sciaena umbra and Scorpaena sp.) whose adult abundances and/or biomass are higher i...
The application of spatially explicit models of population dynamics to fisheries management and the design marine reserve network systems has been limited due to a lack of empirical estimates of larval dispersal. Here we compared assignment tests and parentage analysis for examining larval retention and connectivity under two different gene flow scenarios using panda clownfish ( Amphiprion polymnus ) in Papua New Guinea. A met...
