Individuals that forgo their own reproduction in animal societies represent an evolutionary paradox because it is not immediately apparent how natural selection can preserve the genes underlie non-breeding strategies. Cooperative breeding theory provides a solution to paradox: non-breeders benefit by helping relatives and/or inheriting positions; do disperse breed elsewhere of ecological constraints. However, question why contest within group has rarely been addressed. Here, we use wild...
Plasticity, the capacity of individuals to respond changing environments by modifying traits, may be critically important for population persistence allowing adaptive responses on shorter timescales than genetic change. Here, we use clown anemonefish Amphiprion percula , whose access resources is constrained their anemones, test role plasticity in generating variation reproductive success among groups. We surveyed a wild clownfish and found positive correlations between anemone area, fish...
In social groups, high reproductive skew is predicted to arise when the output of a group limited, and dominant individuals can suppress subordinate efforts. Reproductive suppression often assumed occur via overt aggression or threat eviction. It unclear, however, whether eviction alone sufficient induce restraint by subordinates. Here, we test two assumptions model investigating resource limitation generates competition leads in clown anemonefish Amphiprion percula . First, use feeding...
Animals frequently make adaptive decisions about what to prioritize when faced with multiple, competing demands simultaneously. However, the proximate mechanisms of decision-making in face are not well understood. We explored this question using brain transcriptomics a classic model system: threespined sticklebacks, where males conflict between courtship and territorial defence. characterized behaviour gene expression profiles confronted by trade-off defence comparing them trade-off. When...
Predators exert a powerful selective force, however, predator avoidance can conflict with other important activities such as attracting mates. Decisions over whether to court mates versus avoiding predators are vital fitness, yet the mechanistic underpinnings of how animals manage tradeoffs poorly understood. Here, we investigate flexibility behaviour and gene regulation in response tradeoff between (survival) courting potential (reproduction) three-spined stickleback ( Gasterosteus...
Vertebrate growth can be phenotypically plastic in response to predator-prey and competitive interactions. It is unknown however, if it mutualistic Here we investigate plasticity of vertebrate variation interactions, using clown anemonefish their anemone hosts. In the wild, there a positive correlation between size fish anemone, but cause this unknown. Plausible hypotheses are that exhibit food or space provided by host. lab, pair individuals with real anemones various sizes show on larger...
Abstract Asymmetries in power (the ability to influence the outcome of conflict) are ubiquitous social interactions because interacting individuals rarely identical. It is well documented that asymmetries reproductive conflict groups. Yet have received little attention context negotiations between caring parents, which surprising given parents often markedly different size. Here we built on an existing negotiation model examine how and punishment over care. We incorporated asymmetry by...
Coral reefs are increasingly ecologically destabilized across the globe due to climate change. Behavioural plasticity in corallivore behaviour and short-term trophic ecology response bleaching events may influence extent severity of coral subsequent recovery potential, yet our understanding these interactions situ remains unclear. Here, we investigated between corallivory during a severe high thermal event (10.3-degree heating weeks) Belize. We found that parrotfish changed their grazing by...
Abstract In species with biparental care, conflict arises over how much each parent provides to their offspring because both parents benefit from shifting the burden of care other. Here, we tested alternative hypotheses for will negotiate using a wild population clownfish (Amphiprion percula). We experimentally handicapped by fin-clipping female in 23 groups, male and neither groups measured changes indicators female, male, pair effort response handicapping. First, found that handicapping...
Abstract Understanding drivers of species co-existence on coral reefs is important to predict community responses environmental change. Here, we present, for the first time, observations takeovers anemones occupied by one species, Amphiprion percula , another A. perideraion and ask if habitat characteristics, fish or conditions these occurrences. Comparing survey data from multiple years, find that occur at a frequency 0.48–6.84 per 100 groups/year this does not depend disturbances (anemone...
Each year from 2012 to 2019, during a 12-day period in November or December, we photographed common herpetofauna on Calabash Caye, small mangrove-dominated island the eastern edge of Turneffe Atoll, Belize. Atoll is home newest, largest, and most biodiverse marine protected area Caye exemplifies islands Turneffe’s whose elevated beach ridges enable development coastal strand plain littoral forest habitats, which are among threatened habitats world. As no herpetofaunal survey has been...
Abstract Parental care is a critical component of many breeding systems that enhances both parent and offspring fitness. It widely recognized parental varies in quality quantity response to variation need, condition, ecological context. One context has been underexplored, however, the presence extensive at night, with studies focused on diurnal care. To fully understand evolution care, nocturnal must be accounted for. Here, we show exists clownfish Amphiprion percula , males females actively...
Dispersal, the movement of individuals away from their natal location to another location, is a basic driver ecological and evolutionary processes. Direct measures marine fish larval dispersal have shown that individual distances can vary over several orders magnitude within species. We currently do not know causes this variation. One plausible explanation for cause intraspecific variation in plasticity. Dispersal plasticity, especially as an adaptive parental effect where parents alter...
