Biofouling reduction by lantern nets exchange and its relationship with production and survival of Argopecten purpuratus in Samanco Bay, Peru

open access: yesJournal of the World Aquaculture Society, Volume 56, Issue 5, October 2025.
Abstract The aquaculture of Argopecten purpuratus (Peruvian scallop) is a profitable activity with positive impacts on the local economy. However, the development of biofouling on the culture lantern nets generates negative environmental impacts that affect its sustainability.

Spatial and temporal variability of immature green turtle abundance and somatic growth in Puerto Rico

open access: yesEndangered Species Research, 2014
Understanding conservation needs relies on robust estimates of key population parameters, such as survival, abundance and somatic growth. We investigated the somatic growth and abundance dynamics of 2 aggregations of immature green turtles, at Tortuga ...

Mangrove Pollinator Functional Diversity Decreases With Patch Size and Landscape Anthropization

open access: yesBiotropica, Volume 57, Issue 5, September 2025.
This study explores how land use changes impact pollinator diversity in mangrove ecosystems, focusing on the effects of patch size and landscape anthropization on pollinators with different functional traits. Results show that smaller mangrove patches can support higher pollinator abundance, richness, and diversity; however, overall pollinator metrics ...

Estimating abundance of aggregated populations with drones while accounting for multiple sources of errors: A case study on the mass nesting of Giant South American River Turtles

open access: yesJournal of Applied Ecology, Volume 62, Issue 8, Page 2036-2047, August 2025.
The developed approach can be applied to several contexts to efficiently survey spatially aggregated populations using drone‐derived orthomosaics, and to understand phenology at these aggregation sites. We provide general recommendations for planning surveys and discuss implementations of our approach using other types of marking methods and model ...
