Direct effects and prey‐mediated effects of global change in projections of early life stages of pelagic predators

open access: yesEcography, Volume 2025, Issue 11, November 2025.
Global change will impact the distribution and abundance of predators through a combination of abiotic variables, such as temperature; and biotic variables, such as prey availability. However, there is a poor understanding of how distribution projections with biotic variables differ from those with abiotic variables, particularly in resource‐limited ...

Integrating eDNA and Visual Surveys With Ocean Drift Models to Monitor Marine Mammals in Tropical Waters

open access: yesEnvironmental DNA, Volume 7, Issue 5, September–October 2025.
This study evaluates the effectiveness of environmental DNA (eDNA) metabarcoding for monitoring marine mammals in tropical waters around Réunion Island. By combining visual surveys with eDNA sampling and reverse particle drift modeling, we show that eDNA captures local cetacean presence and offers additional spatial insight when integrated with ...

The essential role of large research vessels in marine ecosystem observations and ocean sustainability

open access: yesLimnology and Oceanography, Volume 70, Issue 9, Page 2767-2792, September 2025.
Abstract Our understanding of marine ecosystems and ability to manage them sustainably has come from multidisciplinary observations made repeatedly over long periods of time. These long‐term ecosystem observations depend on the capabilities of large research vessels, which play an essential role in the collection of global ocean observations.

Spatiotemporal distribution of ichthyoplankton and their relationship with environmental factors in the waters around the Yellow River estuary, China

open access: yesFrontiers in Marine Science
IntroductionThe Yellow River estuary serves as a crucial convergence point between the Yellow River and the Bohai Sea and is a vital spawning, nursery, and feeding ground for a variety of fish species.

Perils of a Drifter: Larval Drift and Entrainment of Freshwater Catfish (Tandanus tandanus) in the Murray–Darling Basin, Australia

open access: yesAustral Ecology, Volume 50, Issue 9, September 2025.
ABSTRACT The freshwater catfish Tandanus tandanus, a species with riverine populations listed as endangered in the Murray–Darling Basin, faces significant conservation challenges. Knowledge about early life stage dispersal remains limited, yet recent larval netting over two spawning seasons in the Macquarie River and adjoining irrigation channels fed ...

Spatial Distribution of Numerical Density of Pelagic Juveniles (0‐Group) of Broadcast Spawning Fish Stocks Follows a Common Statistical Pattern

open access: yesFish and Fisheries, Volume 26, Issue 5, Page 717-732, September 2025.
ABSTRACT Statistical distributions of spatial abundance data of animal populations can be informative about underlying processes and mechanisms that govern the spatial distributions. Here, we examine a large data set from annual 0‐group fish surveys in the Barents Sea (1980–2017) collected with standardised trawl sampling from a regular grid with 30–35

Ichthyoplankton dynamics in a highly urbanized estuary

open access: yesMarine Biology Research, 2015
AbstractSpatio-temporal distribution and composition of ichthyoplankton assemblages were studied in the Golden Horn estuary (Istanbul) over a 10-month period. Environmental parameters were considered to determine the environmental status in different parts (upper, middle and lower) of the estuary.

Recurrence of the Spatial Structure of Summer Larval Fish Assemblages Linked to Hydrodynamics in the NW Mediterranean

open access: yesFisheries Oceanography, Volume 34, Issue 5, Page 99-120, September 2025.
ABSTRACT In this study, we aim to investigate the contribution of various sources of variability, environmental, spatial and interannual on the larval fish assemblages (LFA) in summer off the Catalan coast, an area with a wide array of environmental conditions.

Distribution dynamics of ichthyoplankton and recruitment hypotheses

open access: yesEge Journal of Fisheries and Aquatic Sciences, 2017
Denizel kemikli baliklarin cogunda yumurta ve larval asamalar planktonik ozellik gostermektedir. Bu formlar aktif hareket kabiliyeti kazanincaya dek balik planktonu anlamina gelen ihtiyoplankton kapsaminda degerlendirilmektedir. Kemikli baliklar genellikle cok sayida yumurta uretmekte; bu yumurtalardan onemli bir kismi, aclik, predasyon, anormal ...

Spatial Modelling of Aerial Survey Data Reveals an Important European Storm‐Petrel Hotspot and Its Underlying Drivers Within the North‐East Atlantic

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
Determining the distribution and population size of marine species, especially small pelagic seabirds, such as the European storm‐petrel, is crucial for conservation but is challenging due to their wide ranges, high mobility and cryptic breeding habits.
