Connectivity, or the exchange of individuals among marine populations, is a central topic in ecology. For most benthic species with complex life cycles, this occurs primarily during pelagic larval stage. The small size larvae coupled vast and fluid environment they occupy hamper our ability to quantify dispersal connectivity. Evidence from direct indirect approaches using geochemical genetic techniques suggests that populations range fully open closed. Understanding biophysical processes...
Defining the scale of connectivity, or exchange, among marine populations and determining factors driving this exchange are pivotal to our understanding population dynamics, genetic structure, biogeography many coastal species. Using a high-resolution biophysical model for Caribbean region, we report that typical larval dispersal distances ecologically relevant magnitudes on only 10 100 kilometers variety reef fish We also show importance early onset active movement mediating potential. In...
Most marine populations are thought to be well connected via long-distance dispersal of larval stages. Eulerian and Lagrangian flow models, coupled with linear mortality estimates, were used examine this assumption. The findings show that when simple advection models used, exchange rates may overestimated; such simplistic fail account for a decrease up nine orders magnitude in concentrations resulting from diffusion mortality. alternative process retention near local is shown exist great...

We examine the hypothesis that reef fish larvae have some direct influence on their own dispersal and ability to recruit natal by tracking cohorts of bicolor damselfish ( Stegastes partitus ) from hatching settlement onto reef, about 30 d later. conducted high‐resolution sampling during two consecutive years in a small area (15 km × 20 km) off west coast Barbados, extending depths 0 100 m.

In this paper we review on the technologies available to make globally quantitative observations of particles, in general, and plankton, particular, world oceans, for sizes varying from sub-micron centimeters. Some these have been years while others only recently emerged. Use is critical improve understanding processes that control abundances, distributions composition provide data necessary constrain ecosystem biogeochemical models, forecast changes marine ecosystems light climate change....
A variety of hypotheses have been proposed regarding the processes that regulate survival planktonic life history stages marine organisms. Several these grouped under a general, "growth–mortality" hypothesis, which postulates larger (a "bigger-is-better" mechanism), faster growing "growth-rate" and developing "stage-duration" mechanism) individuals higher probability survival. Using otolith record age, size, ontogeny, three mechanisms hypothesis were tested for larval pelagic juvenile...
Over the last two decades, there has been an accelerating advancement of acoustic and optical plankton samplers, opening many opportunities for fine‐scale studies distribution. To date, however, imaging systems have limited in volume water being sampled, thereby restricting their utility to quantifying highly abundant, small zooplankton like copepods, but not relatively rarer, larger ichthyo‐ other meso‐zooplankton (e.g., larval decapods, salps, pteropods, ctenophores, etc.). Here we...
Ocean acidification affects a wide diversity of marine organisms and is particular concern for vulnerable larval stages critical to population replenishment connectivity. Whereas it well known that ocean will negatively affect range calcareous taxa, the study fishes more limited in both depth understanding species. We used new 3D microcomputed tomography conduct situ analysis impact on otolith (ear stone) size density cobia (Rachycentron canadum), large, economically important, pantropical...
Aim To identify connectivity patterns among coral reefs of the Indo-West Pacific. Projecting forward in time provides a framework for studying long-term source–sink dynamics region, and makes it possible to evaluate manner which migration shapes population genetic structure at regional scales. This information is essential addressing critical gaps knowledge conservation planning efforts one most biologically diverse regions on earth.

Abstract The rise of in situ plankton imaging systems, particularly high‐volume imagers such as the In Situ Ichthyoplankton Imaging System, has increased need for fast processing and accurate classification tools that can identify a high diversity organisms nonliving particles biological origin. Previous methods automated have yielded moderate results either resolve few groups at accuracy or many relatively low accuracy. However, with advent new deep learning convolutional neural networks...
Currently, ocean acidification is occurring at a faster rate than any time in the last 300 million years, posing an ecological challenge to marine organisms globally. There critical need understand effects of on vulnerable larval stages fishes, as there potential for large and economic impacts fish populations human economies that rely them. We expand upon narrow taxonomic scope found literature today, which overlooks many life history characteristics harvested species, by reporting larvae...
Abstract Among marine organisms, gelatinous zooplankton (GZ; cnidarians, ctenophores, and pelagic tunicates) are unique in their energetic efficiency, as the body plan allows them to process assimilate high proportions of oceanic carbon. Upon death, shape facilitates rapid sinking through water column, resulting carcass depositions on seafloor (“jelly‐falls”). GZ thought be important components biological pump, but overall contribution global carbon fluxes remains unknown. Using a...
In the past 100 years since birth of fisheries oceanography, research on early life history fishes, particularly larval stage, has been extensive, and much progress made in identifying mechanisms by which factors such as feeding success, predation, or dispersal can influence survival.However, recent years, study fish undergone a major and, arguably, necessary shift, resulting growing body aimed at understanding consequences climate change other anthropogenically induced stressors.Here, we...
In this study we examined the mechanisms by which Pomatomus saltatrix (Pisces: Pomatomidae) larvae and pelagic juveniles are transported from South Atlantic Bight spawning grounds to Middle estuarine nursery habitats. Data on larval juvenile distributions, recruitment, hydrography, wind speed direction satellite‐derived, sea surface temperature were used examine potential transport mechanisms. On basis of these analyses, a scenario for northward P. was developed. Gulf Stream‐associated flow...
