Demographic dynamics of the smallest marine vertebrates fuel coral reef ecosystem functioning

Science, Journal Year: 2019, Volume and Issue: 364(6446), P. 1189 - 1192

Published: May 23, 2019

Little fish make a big contribution Coral reefs represent one of the most biodiverse and rich ecosystems. Such richness conjures up images coral heads large colorful reef fishes. Brandl et al. show, however, that striking important parts ecosystem is almost never seen (see Perspective by Riginos Leis). Small cryptobenthic fish, like blennies, nearly 40% biodiversity. Furthermore, majority larvae settle locally, rather than being widely dispersed, have rapid turnover rates. high diversity densities could thus provide biomass base for larger, better-known fish.

Causes and consequences of individual variation in animal movement

Movement Ecology, Journal Year: 2020, Volume and Issue: 8(1)

Published: Feb. 17, 2020

Animal movement comes in a variety of 'types' including small foraging movements, larger one-way dispersive seasonally-predictable round-trip migratory and erratic nomadic movements. Although most individuals move at some point throughout their lives, patterns can vary widely across within the same species: differing an individual over time (intra-individual), among population (inter-individual), or populations (inter-population). Yet, studies (theoretical empirical alike) more often focus on understanding 'typical' than variation movement. Here, I synthesize current knowledge (drawing parallels species types), describing causes (what factors contribute to variation), looks like), consequences (why matters), maintenance persists), implications (for management conservation), finally gaps pieces we are currently missing). By synthesizing scales variation, span work plasticity, personality, geographic variation.

Generally less well understood causes, part because effects nested, with manifesting level, which turn affects communities ecosystems.

Finally, maintaining standing may facilitating species' ability respond future environmental change.

Reproductive resilience: a paradigm shift in understanding spawner‐recruit systems in exploited marine fish

Fish and Fisheries, Journal Year: 2016, Volume and Issue: 18(2), P. 285 - 312

Published: Sept. 17, 2016

Abstract A close relationship between adult abundance and stock productivity may not exist for many marine fish stocks, resulting in concern that the management goal of maximum sustainable yield is either inefficient or risky. Although reproductive success tightly coupled with fecundity terrestrial animals, exploited where when spawn consequent dispersal dynamics have a greater impact. Here, we propose an eco‐evolutionary perspective, resilience, to understand connectivity fish. Reproductive resilience capacity population maintain needed result long‐term stability despite disturbances. stock's driven by underlying traits its spawner‐recruit system, selected over evolutionary timescales, ecological context within which it operating. Spawner‐recruit systems are species specific, both density‐dependent fitness feedback loops made up fixed, behavioural ecologically variable traits. They operate multiple temporal, spatial biological scales, trait diversity affecting at individual (i.e. portfolio) scales. Models fall three categories: (i) two‐dimensional models spawner recruit); (ii) process‐based biophysical integrate physical environmental processes into understanding recruitment; (iii) complex spatially explicit integrated life cycle models. We review these their assumptions about vs. our emerging mechanistic understanding. conclude practical guidelines integrating assessments productivity.

Asymmetric oceanographic processes mediate connectivity and population genetic structure, as revealed byRADseq, in a highly dispersive marine invertebrate (Parastichopus californicus)

Molecular Ecology, Journal Year: 2018, Volume and Issue: 27(10), P. 2347 - 2364

Published: April 14, 2018

Abstract Marine populations are typically characterized by weak genetic differentiation due to the potential for long‐distance dispersal favouring high levels of gene flow. However, strong directional advection water masses or retentive hydrodynamic forces can influence degree exchange among marine populations. To determine oceanographic drivers structure in a highly dispersive invertebrate, giant California sea cucumber ( Parastichopus californicus ), we first tested presence discontinuities along coast North America northeastern Pacific Ocean. Then, two hypotheses regarding spatial processes influencing population structure: (i) isolation distance IBD : is explained geographic distance) and (ii) resistance IBR driven ocean circulation). Using RAD seq, genotyped 717 individuals from 24 sampling locations across 2,719 neutral SNP s assess integrated estimates variation with inferred connectivity probabilities biophysical model larval mediated currents.

Beyond Reproductive Isolation: Demographic Controls on the Speciation Process

Annual Review of Ecology Evolution and Systematics, Journal Year: 2019, Volume and Issue: 50(1), P. 75 - 95

Published: July 12, 2019

Studies of speciation typically investigate the evolution reproductive isolation between populations, but several other processes can serve as key steps limiting formation species. In particular, probability successful be influenced by factors that affect frequency with which population isolates form well their persistence through time. We suggest and have an inherently spatial dimension profitably studied using a conceptual framework drawn from metapopulation ecology. discuss models incorporate demographic highlight need for broader application phylogenetic comparative approaches to evaluate general importance isolation, persistence, in speciation. review diverse nontraditional data sources leveraged study framework. This incorporation information facilitates integration perspectives on across disciplines timescales.

Successful validation of a larval dispersal model using genetic parentage data

PLoS Biology, Journal Year: 2019, Volume and Issue: 17(7), P. e3000380 - e3000380

Published: July 12, 2019

Larval dispersal is a critically important yet enigmatic process in marine ecology, evolution, and conservation. Determining the distance direction that tiny larvae travel open ocean continues to be challenge. Our current understanding of larval patterns at management-relevant scales principally separately informed by genetic parentage data biological-oceanographic (biophysical) models. Parentage datasets provide clear evidence individual events, but their findings are spatially temporally limited. Biophysical models offer more complete picture regional uncertain accuracy. Here, we develop statistical techniques integrate these two sources information on dispersal. We then apply methods an extensive dataset successfully validate high-resolution biophysical model for economically reef fish species Plectropomus maculatus southern Great Barrier Reef. results demonstrate can accurate descriptions spatial temporal relevant management. They also show enough power exclude poor included species-specific behaviour provided markedly better fits than assuming passive behaviour, incorrect behavioural assumptions led worse predictions ignoring altogether. approach capitalises complementary strengths produce scales.

Structure and stability of the coral microbiome in space and time

Scientific Reports, Journal Year: 2019, Volume and Issue: 9(1)

Published: May 1, 2019

Abstract Although it is well established that the microbial communities inhabiting corals perform key functions promote health and persistence of their hosts, little known about spatial structure temporal stability. We examined natural variability associated with six Caribbean coral species from three genera at four reef sites over one year. identified differences in community composition between persisted across space time, suggesting local host identity likely plays a dominant role structuring microbiome. However, we found dissimilarity increased geographical distance, which indicates regional processes such as dispersal limitation spatiotemporal environmental heterogeneity also influence composition. In addition, network analysis revealed strength varied genera, genus Acropora having most community. Overall, our results demonstrate despite high levels diversity, are characterized by signature microbiomes stable both time.
