Climate change impacts on fishery resources have been widely reported worldwide. Nevertheless, a knowledge gap remainsvfor the warm-temperate Southwest Atlantic Ocean—a global warming hotspot that sustains important industrial and small-scale fisheries. By combining a trait-based framework and long-term landing records, we assessed species’ sensiti...
Large-scale spatial and temporal variability in environmental conditions may result in differences in life-history traits, population demography, and abundance of sandy-beach species. We analyzed the effects of salinity, chlorophyll a (chl a), and sea surface temperature (SST) on population parameters of the wedge clam Donax hanleyanus from 75 Sout...
Changes in the structure and dynamics of sandy beach macrofaunal populations result from the simultaneous action of local and regional factors acting synergistically. This is particularly noticeable in transitional interfaces between freshwater and marine ecosystems, where large-scale gradients affect local beach morphodynamics and resident fauna....
Despite the global occurrence of microplastic contamination on sandy beaches, evidence of microplastic distribution within beaches remains contradictory. When conflicting evidence is used to inform sampling surveys, it increases uncertainty in resulting data. Moreover, it hampers spatially explicit risk characterization of microplastic pollution to...
As a land-sea interface, the fingerprints of climate perturbations may be immediately and profoundly felt in sandy beaches and the macroinvertebrates they harbour. In particular, extreme climatological events can result in long-lasting or irreversible ecological changes, and therefore, it has become critical to understand how these ecosystems respo...
Studies comparing the distribution of genetic diversity may help revealing connectivity patterns in marine populations, as they allow identifying factors behind genetic population structure and elucidating the relationship between the habitat and resident species. The macrofauna of sandy beaches constitutes an interesting study subject, since it in...
The biophysical mechanisms influencing larval distribution and their impacts on the metapopulation dynamics of sandy beaches, particularly the connectivity patterns associated with larval dispersal, are poorly understood. Here, we identify larval connectivity patterns of the mole crab Emerita brasiliensis in the coast of Uruguay. A biophysical indi...
Knowledge on the status and trends in marine biodiversity, and associated drivers of biodiversity change across the Americas is sparse and geographically uneven. International cooperation is needed to fill observational gaps at these geographic scales and provide information to satisfy policy targets of the 2030 Agenda for Sustainable Development a...
Presence of plastics in the Uruguayan ichthyofauna
Spatial and temporal environmental heterogeneity influences biodiversity distribution patterns and dynamics on sandy beaches. In these ecosystems, the microscale vertical distribution adds a dimension to the analysis of biological and physical processes, whose ecological patterns have been rarely described. An intensive across-shore sampling in a d...
Las características de la historia de vida en bivalvos pueden estar influenciadas por la temperatura del mar, salinidad, disponibilidad de alimento y densidad, entre otras. Además para las especies, en organismos que habitan intermareales de playas arenosas se propone que dichas poblaciones están afectadas por la morfodinámica costera, planteándose...
Structural and functional changes in a sandy beach ecosystem in the southwestern Atlantic (Barra del Chuy, Uruguay) were assessed by contrasting four Ecopath trophic models and performing temporal dynamic simulations using Ecosim. Each model (1982, 1989, 1996 and 2012) represents a historical period of a clam fishery in which regulatory structure,...
Climate change is expected to have considerable impacts on sandy beach ecosystems through the loss of intertidal area and changes in physical properties. These changes may affect demography and life history traits of macrofaunal species. We evaluated the role of climate in explaining variations in population traits of the mole crab Emerita brasilie...
Sandy beaches are being threatened by a changing climate. However, the effects of this changing environment, including warming, on these ecosystems, have hitherto been tentative and qualitative. Using concurrent long-term (1984?2007) observations on abundance and individual size, together with laboratory examinations of body abnormalities (morpholo...

Coconut Creek (Florida), ISSN 0749-0208. Effects of long-term trends in climatic variability on the morphodynamics of a reflective and a dissipative sandy beach in U...
Several conceptual models relating biological and morphodynamic variables have been developed in sandy beach ecology. On estuarine sandy beaches, a major environmental factor influencing macrofaunal distribution is salinity. In this setting, the concurrent role of large-scale estuarine and morphodynamic gradients in shaping demographic patterns is...
[Caprella bathytatos Martin & Pettit, 1998, knowm from a marine hydrothermal vent in the Juan de Fuca Ridge, British Columbia, Canada, is reported from the southwestern Atlantic Ocean associated with the mouthparts and the cephalothorax of Lithodes santolla (Molina, 1782). This is the first report of this species associated with a lithodid crab and...
Una gran cantidad de pesquerías a nivel mundial se encuentran sobreexplotadas o colapsadas, en especial las costeras. Esto es de vital importancia, pues la dependencia de los recursos costeros es cada vez mayor. En Uruguay la situación no difi ere de esta realidad, por lo cual son necesarias medidas de manejo pesquero que contemplen un uso sostenib...
The habitat harshness hypothesis (HHH) postulates that in reflective beaches the harsh environment forces organisms to divert more energy towards maintenance and they therefore have lower abundance, fecundity, growth and survival rates than in dissipative beaches. Recent investigations have tested this hypothesis through single comparisons of only...
This paper analyses the spatial and temporal effects of a freshwater discharge (Canal Andreoni) on the macroinfauna community and its habitat in a sandy beach of Uruguay. Bimonthly, we examined 17 environmental variables plus macroinfauna abundance, biomass, richness, evenness and diversity of three sites: Andreoni, at the canal mouth, Coronilla, a...
