Effects of forest cover on richness of threatened fish species in Japan. [PDF]

open access: yesConserv Biol, 2022
Abstract Estuaries––one of the most vulnerable ecosystems globally––face anthropogenic threats, including biodiversity loss and the collapse of sustainable fisheries. Determining the factors contributing to the maintenance of estuarine biodiversity, especially that of fish, is vital for promoting estuarine conservation and sustainability.

Temperature Conditions in Artificial Sea Turtle Nests: Toward Optimized Hatchery Management. [PDF]

open access: yesEcol Evol
This study examined how environmental and management factors, such as wall distance and egg numbers, influence nest temperatures of Olive Ridley sea turtles in a hatchery on the Pacific coast of Guatemala. ABSTRACT Climate change poses a significant threat to species with temperature‐dependent sex determination, such as sea turtles.

Global warming facilitates the nesting of the loggerhead turtle on the Mediterranean coast of Spain

open access: yesAnimal Conservation, Volume 26, Issue 3, Page 365-380, June 2023., 2023
Average summer sand temperature (July 20th–August 10th) at 40 cm deep in Spanish Mediterranean beaches, as reconstructed from air temperature at El Prat beach, has increased from 1950 to 2019 (top figure). As a result, the duration of the viable nesting window for loggerhead turtles (bottom figure) has also increased and the thermal environment has ...

A metabarcoding protocol targeting two DNA regions to analyze root‐associated fungal communities in ferns and lycophytes

open access: yesApplications in Plant Sciences, Volume 11, Issue 3, May-June 2023., 2023
Abstract Premise Detailed studies of the fungi associated with lycophytes and ferns provide crucial insights into the early evolution of land plants. However, most investigations to date have assessed fern–fungus interactions based only on visual root inspection. In the present research, we establish and evaluate a metabarcoding protocol to analyze the

Successional and phenological effects on plant‐floral visitor interaction networks of a tropical dry forest

open access: yesJournal of Ecology, Volume 111, Issue 4, Page 927-942, April 2023., 2023
Our results showed that plant‐floral visitor interactions are dynamic and vary with flowering phenology and with successional changes in plant and animal diversity. Plant‐floral visitor interactions were more diverse and specialised in the late successional stages.

Can we manage marine mammal bycatch effectively in low‐data environments?

open access: yesJournal of Applied Ecology, Volume 58, Issue 3, Page 596-607, March 2021., 2021
Here we develop three alternative methods that expand the toolbox of approaches available for use in determining marine mammal conservation reference points for human‐caused mortality when it is not possible to apply the more standard, data‐hungry Potential Biological Removal approach.
