The PCR-based analysis of homologous genes has become one the most powerful approaches for species detection and identification, particularly with recent availability Next Generation Sequencing platforms (NGS) making it possible to identify composition from a broad range environmental samples. Identifying these samples relies on ability match sequences reference barcodes taxonomic identification. Unfortunately, studies have targeted ribosomal markers, despite fact that mitochondrial...
We use an approach based on phylogenetic comparisons to identify life history correlates of abundance trends in 18 intensively exploited fish stocks from the north–east Atlantic. After accounting for differences fishing mortality, we show that those fishes have decreased compared with their nearest relatives mature later, attain a larger maximum size, and exhibit significantly lower potential rates population increase. Such were not evident more traditional cross–species analysis. This is...
Human activities can create noise pollution and there is increasing international concern about how this may impact wildlife. There evidence that anthropogenic have detrimental effects on behaviour physiology in many species but are few examples of experiments showing fitness be directly affected. Here we use a split-brood, counterbalanced, field experiment to investigate the effect repeated boat-noise playback during early life development survival marine invertebrate, sea hare Stylocheilus...
Understanding the role of predators in food webs can be challenging highly diverse predator/prey systems composed small cryptic species. DNA based dietary analysis supplement predator removal experiments and provide high resolution for prey identification. Here we use a metabarcoding approach to initial insights into diet functional coral-dwelling predatory fish feeding on invertebrates. Fish were collected Moorea (French Polynesia) where BIOCODE project has generated barcodes numerous coral...
Some anthropogenic noise is now considered pollution, with evidence building that from human activities such as transportation, construction and exploration can impact behaviour physiology in a broad range of taxa. However, relatively little research has the effects repeated or chronic noise; extended exposures may result habituation sensitisation, thus changes response. We conducted field-based experiment at Moorea Island to investigate how exposure playback motorboat affected coral reef...
Anthropogenic noise is an emergent ecological pollutant in both terrestrial and aquatic habitats. Human population growth, urbanisation, resource extraction, transport motorised recreation lead to elevated that affects animal behaviour physiology, impacting individual fitness. Currently, we have a poor mechanistic understanding of the effects anthropogenic noise, but likely candidate neuroendocrine system integrates information about environmental stressors produce regulatory hormones;...
Despite numerous indices proposed to predict the evolution of mating systems, a unified measure sexual selection has remained elusive. Three previous studies have compared under laboratory conditions. Here, we use genetic study compare most widely used measures in natural populations. We explored and reproductive successes male female bank voles, Clethrionomys glareolus , across manipulated operational sex ratios (OSRs) by genotyping all adult pup voles on 13 islands using six microsatellite...
The physiological and behavioral mechanisms underlying life-history trade-offs are a continued source of debate. Testosterone (T) is one factor proposed to mediate the trade-off between reproduction survival. We use phenotypic engineering multiple laboratory field fitness-related traits test effects elevated T two bank vole Myodes glareolus groups: dominant subordinate males. Males with naturally high levels showed higher social status (laboratory dominance) mobility (distance capture sites)...
Selection of rare-male types in a population can maintain genetic variation that benefits one sex but harms the other.
Characterization of predator-prey interactions is challenging as researchers have to rely on indirect methods that can be costly, biased and too imprecise elucidate the complexity food webs. DNA amplification sequencing techniques gut fecal contents are promising approaches, but their success largely depends ability amplify taxonomic array prey consumed then match amplicons with reference sequences. When little a priori information diet available or generalist predator targeted, versatile...
Populations of fishes provide valuable services for billions people, but face diverse and interacting threats that jeopardize their sustainability. Human population growth intensifying resource use food, water, energy goods are compromising fish populations through a variety mechanisms, including overfishing, habitat degradation declines in water quality. The important challenges raised by these issues have been recognized led to considerable advances over past decades managing mitigating...
Artificial light at night (ALAN) is an increasing anthropogenic pollutant, closely associated with human population density, and now well recognized in both terrestrial aquatic environments. However, we have a relatively poor understanding of the effects ALAN marine realm. Here, carried out field experiment coral reef lagoon Moorea, French Polynesia, to investigate long-term exposure (18–23 months) chronic pollution on survival growth wild juvenile orange-fin anemonefish, Amphiprion...
Sexual selection predicts that trade-offs maintain trait variation in alternative reproductive strategies. Experiments often focus on testosterone (T), but the gonadotropins follicle-stimulating hormone and luteinizing may provide a clearer understanding of pleiotropic relationships among traits. We assess activational role T corticosterone regulation traits expressed by polymorphic male side-blotched lizards Uta stansburiana. Gonadotropins are found to enhance suppress multiple...
Trade-offs are widespread between life-history traits, such as reproduction and survival. However, their underlying physiological behavioral mechanisms less clear. One proposed factor involves the trade-off investment in male reproductive effort immunity. Based on this hypothesis, we investigated differences fitness artificially selected immune response bank vole groups, Myodes glareolus. Significant heritability of was found a correlated testosterone levels to selection function. Male...
During a survey of the population blacktip reef shark Carcharhinus melanopterus in Moorea (French Polynesia) between 2007 and 2011, structural characteristics were estimated from 268 individuals. Total length ( L T ) ranged 48 to 139 cm 157 for males females, respectively, demonstrating that average females was larger than males. The C. at showed an apparent spatial sexual segregation with preferentially frequenting lagoons fore‐reefs. Mean growth rate c . 6 year −1 Males reached maturity...
Abstract Organisms can behaviorally, physiologically, and morphologically adjust to environmental variation via integrative hormonal mechanisms, ultimately allowing animals cope with change. The stress response social changes commonly promotes survival at the expense of reproduction. However, despite climate change impacts on population declines diversity loss, few studies have attributed responses, or their regulatory effects, in wild. Here, we report fitness responses individual wild fish...
Intralocus sexual conflict occurs when a trait encoded by the same genetic locus in two sexes has different optima males and females. Such is widespread across taxa, however, shared phenotypic traits that mediate are largely unknown. We examined whether sex hormone, testosterone (T), controls differentiation, contributes to sexually antagonistic fitness variation bank vole, Myodes glareolus . compared (opposite-sex) sibling reproductive vole after creating divergent selection lines for T....
Although benthic motile invertebrate communities encompass the vast majority of coral reef diversity, their response to habitat modification has been poorly studied. A variety species, particularly decapods, provide benefits host enabling them cope with environmental stressors, and as a result benefit overall diversity coral-associated species. However, little is known about how assemblages associated corals will be affected by global perturbations, (either directly or indirectly via host)...
Crown-of-thorns sea star (CoTS) outbreaks are one of the leading causes hard coral cover decline across Indo-Pacific, posing a major threat to health and resilience reefs. However, drivers underlying feeding on preferred (e.g., Acropora spp.) versus non-preferred Porites poorly understood. We hypothesised that venom may influence CoTS food preferences. investigated whether toxin peptide families drive prey preferences by comparing genomes transcriptomes (five species) species Echinopora...
