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;...
While chance events, oceanography and selective pressures inject stochasticity into the replenishment of marine populations with dispersing life stages, some determinism may arise as a result characteristics breeding individuals. It is well known that larger females have higher fecundity, recent laboratory studies shown maternal traits such age size can be positively associated offspring growth, survival. Whether fecundity effects translate recruitment in remains largely unanswered. We...
Long pelagic larval phases and the absence of physical barriers impede rapid speciation contrast high diversity observed in marine ecosystems such as coral reefs. In this study, we used three-spot dascyllus (Dascyllus trimaculatus) species complex to evaluate modes at spatial scale Indo-Pacific. The includes four recognized main color morphs that differ distribution. Previous studies group using mitochondrial DNA revealed a noncongruence between genetic groupings; with two grouped together...
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...
Reef fishes exhibit a bipartite life cycle where benthic adult stage is preceded by pelagic dispersal phase during which larvae are presumed to be mixed and transported oceanic currents. Genetic analyses based on twelve microsatellite loci of 181 three-spot dascyllus (Dascyllus trimaculatus) that settled concurrently small reef in French Polynesia revealed 11 groups siblings (1 full sibs 10 half-sibs). This the first evidence fish can journey together throughout their entire planktonic...
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...
Abstract This article documents the addition of 283 microsatellite marker loci to Molecular Ecology Resources Database. Loci were developed for following species: Agalinis acuta ; Ambrosia artemisiifolia Berula erecta Casuarius casuarius Cercospora zeae‐maydis Chorthippus parallelus Conyza canadensis Cotesia sesamiae Epinephelus acanthistius Ficedula hypoleuca Grindelia hirsutula Guadua angustifolia Leucadendron rubrum Maritrema novaezealandensis Meretrix meretrix Nilaparvata lugens...
Temperate mesophotic reef ecosystems (TMREs) are among the least known marine habitats. Information on their diversity and ecology is geographically temporally scarce, especially in highly productive large upwelling ecosystems. Lack of information remains an obstacle to understanding importance TMREs as habitats, biodiversity reservoirs connections with better-studied shallow reefs. Here, we use environmental DNA (eDNA) from water samples characterize community composition central Chilean...
Human-made noise is contributing increasingly to ocean soundscapes. Its physical, physiological and behavioural effects on marine organisms are potentially widespread, but our understanding remains largely limited intraspecific impacts. Here, we examine how motorboats affect an interspecific cleaning mutualism critical for coral reef fish health, abundance diversity. We conducted in situ observations of interactions between bluestreak cleaner wrasses (Labroides dimidiatus) their clients...
Abstract Observer presence can bias behavioural studies of animals in both the wild and laboratory. Despite existing evidence for significant observer effects across several taxa, little is known about minimum periods acclimation that should precede observations. To date, most either do not report any or include a non‐specific period without empirically quantifying its appropriateness. Here, we conducted situ observations two species demersal coral reef fishes using cameras and/or observers...
Increased ocean temperatures are causing mass bleaching of anemones and corals in the tropics worldwide. While such heat-induced loss algal symbionts (zooxanthellae) directly affects physiologically, this damage may also cascade on to other animal symbionts. Metabolic rate is an integrative physiological trait shown relate various aspects organismal performance, behaviour locomotor capacity, shows plasticity during exposure acute chronic stressors. As climate warming expected affect...
Abstract Environmentally-induced changes in fitness are mediated by direct effects on physiology and behaviour, which tightly linked. We investigated how predicted ocean warming (OW) acidification (OA) affect key ecological behaviours (locomotion speed foraging success) metabolic rate of a keystone marine mollusc, the sea hare Stylocheilus striatus , specialist grazer toxic cyanobacterium Lyngbya majuscula . acclimated hares to OW and/or OA across three developmental stages (metamorphic,...
Abstract The mutualism between clownfishes (or anemonefishes) and their giant host sea anemones are among the most immediately recognizable animal interactions on planet have attracted a great deal of popular scientific attention [1-5]. However, our evolutionary understanding this iconic symbiosis comes almost entirely from studies clownfishes— charismatic group 28 described species in genus Amphiprion [2]. Adaptation to venomous (Anthozoa: Actiniaria) provided with novel habitat space,...
Oceanographic features influence the transport and delivery of marine larvae, physical retention mechanisms, such as eddies, can enhance self-recruitment (i.e. return larvae to their natal population). Knowledge exact locations hatching (origin) settlement (arrival) reef animals provides a means compare observed patterns 'connectivity' with those expected from water circulation patterns. Using parentage inference based on multiple sampling years in Moorea, French Polynesia, we describe...
The largely unexplored diversity in temperate mesophotic ecosystems (TME, ~30–150 m depth) has attracted much attention over the past years. However, number of studies and knowledge TME ecology remains limited geographically restricted. absence information on how assemblages vary across environmental gradients with depth for most regions also limits our capacity to delimit conservation areas devise management plans effectively. This study focuses from central Chile describes distribution...
The pelagic larval duration ( D PL ) for 10 temperate cryptobenthic species belonging to three families: Gobiidae, Gobiesocidae and Blenniidae was investigated. Overall, the presented short s varying between 11 18 days, Gobiidae’s ranged 14 39 Parablennius pilicornis (Blenniidae) had an average of 33 days (range 31–37 days). Two subtypes settlement marks were found among individuals same species.
As with many marine species, the vast majority of coral-reef fishes have a bipartite life cycle consisting dispersive larval stage and benthic adult stage. While potentially far-reaching demographic ecological consequences dispersal are widely appreciated, little is known structure pool process itself. Utilizing Palindrome Sequence Analysis otolith micro-chemistry (PaSA;) we show that larvae Neopomacentrus miryae (Pomacentridae) appear to remain in cohesive cohorts throughout their entire...
Abstract Climate change causes extreme heat waves that have induced worldwide mass coral bleaching. The impacts of temperature‐induced bleaching events on the loss algal endosymbionts in both corals and anemones are well documented. However, cascading animals live association with understudied. We performed a field‐based experiment to investigate how host anemone affected metabolic rate, growth, behaviour survival wild juvenile orange‐fin anemonefish Amphiprion chrysopterus over 1, 2 (for...
In this study, we compare the composition, abundance and structure of a temperate fish larval assemblage at different depth intervals (0–4, 4–8 8–12 m) in extreme nearshore environment. We used plankton net attached to an underwater scooter sample close proximity rocky substrate (<50 cm). A total 868 larvae from 27 taxa 13 families were caught. The majority belonged benthic reef-associated species (Blenniidae, Gobiidae, Gobiesocidae Tripterygiidae), four most abundant comprising 76%...
We tested whether vicariance or dispersal was the likely source of speciation in genus Clepticus by evaluating evolutionary timing effect mid-Atlantic barrier, which separates C. brasiliensis and africanus, Amazon parrae C brasiliensis. Genetic data from three mitochondrial genes one nuclear gene were used. Mitochondrial separated into well supported clades corresponding to recognized allopatric morpho-species. All analyses provided consistent support for an initial separation (~9.68 1.86...
Abstract Passive acoustic monitoring can offer insights into the state of coral reef ecosystems at low-costs and over extended temporal periods. Comparison whole soundscape properties rapidly deliver broad from data, in contrast to more detailed but time-consuming analysis individual bioacoustic signals. However, a lack effective automated for data has impeded progress this field. Here, we show that machine learning (ML) be used unlock greater soundscapes. We showcase on diverse set tasks...
Outbreaks of the corallivorous crown-of-thorns seastar Acanthaster planci (COTS) represent one greatest disturbances to coral reef ecosystems in Indo-Pacific, affecting not only reefs but also coastal communities which rely on their resources. While injection approaches are increasingly used an attempt control COTS densities, most them display severe drawbacks including logistical challenges, high residual environmental impacts or low cost-effectiveness. We tested a new alternative method...
