Lack of Compliance in Gillnet Fisheries Regulations Increases Risk to a Vulnerable Species

Fisheries Management and Ecology, Volume 33, Issue 5, Page 933-948, October 2026.
ABSTRACT This article presents an analysis of regulatory compliance in a Brazilian gillnet fishery, based on Vessel Monitoring System (VMS) tracking data. Satellite transmissions records, interpreted as proxies for gillnet haulings events, were analyzed and classified using a neural network to assess the level of compliance of the gillnet fleet.

Influence of the Freshwater Discharge on the Hydrodynamics of Patos Lagoon, Brazil

International Journal of Geosciences, 2014
Patos Lagoon is a very dynamic environment presenting hydrodynamic fluctuations from synoptic to decadal timescales. Thus, understanding the processes that determine the long term variability is fundamental for the correct coastal planning and management of this region. The main objective of this study is to understand how the freshwater discharge

Assimilation of Velocity Data for Tidal Hydrodynamics Model Calibration

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract Assessing tidal stream energy resource typically involves the application of numerical models calibrated against sparse Acoustic Doppler Current Profiler (ADCP) data. This introduces significant challenges in energetic sites which are prone to significant spatiotemporal variations, like the Pentland Firth, Scotland, which is home to the world ...

Shoreline Evolution of Lagoon Sandy Spits and Adjacent Beaches, Lagoa dos Patos, Brazil

, 2019
The development of lagoon sandy spits is dependent on sediment supply (mainly through longshore transport) and is often related to erosion of updrift beaches under high-angle waves.

Location of Shops and Services: A Local Perspective on Accessibility in Southern Brazil

Transactions in GIS, Volume 30, Issue 4, June 2026.
ABSTRACT Urban accessibility strongly influences the spatial distribution of economic activities and supports planning aimed at territorial equity. This study examines the location of shops and services in Laranjal, Pelotas (Brazil), using accessibility measured by closeness centrality.

Trophic Niche Overlap Between the Invasive Crab Rhithropanopeus harrisii (Gould, 1841) and Native Crab Species in the Southwest Atlantic Coast

Marine Ecology, Volume 47, Issue 3, May/June 2026.
ABSTRACT The introduction of exotic species is one of the main drivers of biodiversity loss in aquatic ecosystems. The Harris mud crab Rhithropanopeus harrisii, native to the Atlantic coast of North America, was recorded in the Patos Lagoon estuary (southern Brazil) in the 1980s, likely introduced via ballast water. However, the effects of this invader

Small jellyfish, large consequences: The overlooked predatory role of hydromedusae in subtropical estuarine ecosystems

Limnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract Hydromedusae are often overlooked in pelagic trophic ecology compared to large scyphozoans. We investigated the diet, prey selectivity, ingestion rates, digestion times, and predation impacts of the native Liriope tetraphylla and non‐indigenous species Cnidostoma fallax and Moerisia inkermanica in a subtropical estuary of the southwestern ...
