Seasonal variation in carbon sources of mesograzers and small predators in an eelgrass community: stable isotope and fatty acid analyses [PDF]

, 2011
We assessed the seasonal change in trophic interactions at the mesograzer and small predator level in a temperate eelgrass system. This was done through stable isotope (δ13C and δ15N) and fatty acid analyses of eelgrass Zostera marina, attached epiphytes,

Coupled Multivariate Analyses Reveal Separate Climate and Local Drivers of Temporal and Spatial Change in a Coastal Marine Ecosystem

Ecology and Evolution, Volume 15, Issue 7, July 2025.
A set of readily available multivariate tools was used in a complementary way to identify and better understand both the inter‐annual and spatial patterns in a fish and mobile invertebrate community in the Peconic Estuary. We found distinctly different drivers for temporal and spatial patterns, with temporal factors operating on a regional scale and ...

Removal of Sea Lettuce, Ulva spp., in Estuaries to Improve the Environments for Invertebrates, Fish, Wading Birds, and Eelgrass, Zostera marina [PDF]

, 2005
Mats (biomasses) of macroalgae, i.e. Ulva spp., Enteromorpha spp., Graciolaria spp., and Cladophora spp., have increased markedly over the past 50 years, and they cover much larger areas than they once did in many estuaries of the world.

Connectivity and Population Structure in a Marginal Sea—A Review

Diversity and Distributions, Volume 31, Issue 7, July 2025.
ABSTRACT Aim The current biodiversity crisis calls for conservation measures that limit or reduce the negative human impact on key habitats and vulnerable wild populations. To effectively protect biodiversity at all levels, including intra‐specific diversity, conservation measures should, ideally, be aligned with the connectivity and genetic structure ...

The ways in which fish use estuaries: a refinement and expansion of the guild approach [PDF]

, 2013
© 2013 John Wiley & Sons Ltd. This study refines, clarifies and, where necessary, expands details of the guild approach developed by Elliott et al. (2007, Fish and Fisheries 8: 241-268) for the ways in which fish use estuaries.

Assessing conservation priorities for seahorses in Brazil reveals gaps in current protected areas

Conservation Science and Practice, Volume 7, Issue 6, June 2025.
Abstract Seahorses are rare and threatened marine species facing increasing risks from habitat degradation and overexploitation. Understanding their distribution is critical for effective conservation planning, yet comprehensive studies are limited, including in Brazil. This study aimed to conduct a gap analysis and identify priority areas for seahorse

Biological responses to a resumption in river flow in a freshwater-deprived, permanently open Southern African estuary [PDF]

, 2008
The Kariega Estuary is a freshwater-deprived system due to numerous impoundments in the catchment. This system has had little or no horizontal salinity gradient over the last 15 years, with hypersaline conditions sometimes predominating in the upper ...

Genetic Diversity and Connectivity of Syngnathid Fish in Spanish National Parks: Conservation Insights From Protected Marine Ecosystems

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 3, March 2025.
ABSTRACT Spanish National Parks (NPs) are protected areas for biodiversity conservation, including two Maritime–Terrestrian NPs: The Atlantic Islands of Galicia, PNIA (NW Spain) and Archipelago of Cabrera, PNAC (Balearic Islands). This study was aimed to conduct a 3‐year genetic survey of syngnathid fish species (i.e. seahorses and pipefish) identified

Overview of the Fish Diversity of Indian Waters [PDF]

, 2018
Fishing is one of the oldest human activities and it developed gradually, when our ancestors moved from the collection of plants and animals to hunting by using tools and weapons. The oldest fishing implements so far identified are harpoons, found in
