Temporal changes in gene expression and genotype frequency of the ornithine decarboxylase gene in native silverside Basilichthys microlepidotus: Impact of wastewater reduction due to implementation of public policies

Evolutionary Applications, Volume 13, Issue 6, Page 1183-1194, July 2020., 2020
Abstract Human activity has caused a deterioration in the health and population size of riverine species; thus, public policies have been implemented to mitigate the anthropogenic impacts of water use, watercourse transformation, and pollution. We studied the Maipo River Basin, one of the most polluted with untreated wastewater in Chile, for a period ...

El conocimiento de la Posidonia oceanica y sus funciones ecológicas como herramienta de gestión litoral. La realización de encuestas a los usuarios de playas y calas de la isla de Menorca

Papeles de Geografí­a, 2001
La Posidonia oceanica juega un papel primordial como producción de sedimento y defensa de las playas y calas de la isla de Menorca. La realización de encuestas de percepción a los usuarios de playa sobre el conocimiento y las funciones ecológicas de ...

Estado trófico y estructura comunitaria del microfitoplancton en un sector del golfo de Guayaquil, Ecuador

Biota Colombiana, 2018
El incremento urbano en zonas costeras ha conducido a la eutrofización, cuya acumulación de residuos orgánicos ha afectado también al estuario del golfo de Guayaquil; por ello, se determinó el estado trófico utilizando el índice Karydis, a una milla del

Coinvasional disruptions to island pollinator networks

Conservation Biology, Volume 40, Issue 5, October 2026.
Abstract Biological invasions can adversely affect pollinator diversity by threatening the maintenance of animal‐pollinated plant communities. Although most studies have examined single invasive species, accelerating species introductions driven by global trade highlight the need to understand how multiple co‐occurring invaders jointly influence ...

From species lists to interactions: Network structure, not richness, guides seed dispersal management in human‐modified islands

Journal of Applied Ecology, Volume 63, Issue 5, May 2026.
Our findings show that management strategies can create fundamentally different seed dispersal regimes, even under similar environmental conditions. Anthropogenic diversification reshapes network organisation into distinct structural configurations, rather than consistently enhancing overall cohesion.

Seasonal Variability of the Southern Tip of the Oxygen Minimum Zone in the Eastern South Pacific (30°‐38°S): A Modeling Study

Journal of Geophysical Research: Oceans, Volume 124, Issue 12, Page 8574-8604, December 2019., 2019
Abstract We investigate the seasonal variability of the southern tip (30°–38°S) of the eastern South Pacific oxygen minimum zone (OMZ) based on a high horizontal resolution (1/12°) regional coupled physical‐biogeochemical model simulation. The simulation is validated by available in situ observations and the OMZ seasonal variability is documented.

Global insular leaf size shifts follow the island rule, independently of insect herbivory and macroclimate

Journal of Ecology, Volume 114, Issue 2, February 2026.
We found a positive, non‐linear, saturating relationship between mainland and island leaf sizes, reflecting an island rule‐like pattern. Small‐leaved mainland species tend to develop larger leaves on islands, while this effect weakens for larger‐leaved species, a pattern consistent across both conspecific and congeneric comparisons. Abstract The island
