Detecting selective logging in tropical forests with optical satellite data: an experiment in Peru shows texture at 3 m gives the best results

Remote Sensing in Ecology and Conservation, Volume 11, Issue 1, Page 100-118, February 2025.
Selective logging is known to be widespread in the tropics, but is currently very poorly mapped. To improve this, we used in‐situ measurements of aboveground biomass loss (∆AGB) collected from selectively logged permanent sample plots in the southern Peruvian Amazon.

Island restoration to rebuild seabird populations and amplify coral reef functioning

Conservation Biology, Volume 39, Issue 1, February 2025.
Abstract Mobile organisms like seabirds can provide important nutrient flows between ecosystems, but this connectivity has been interrupted by the degradation of island ecosystems. Island restoration (via invasive species eradications and the restoration of native vegetation) can reestablish seabird populations and their nutrient transfers between ...

Testing reliability and validity of practitioner‐rated parental sensitivity: A novel tool for practice

Infant Mental Health Journal: Infancy and Early Childhood, Volume 45, Issue 2, Page 234-246, March 2024.
Abstract Improving parental sensitivity is an important objective of interventions to support families. This study examined reliability and validity of parental sensitivity ratings using a novel package of an e‐learning tool and an interactive decision tree provided through a mobile application, called the OK! package.

Global status, impacts, and management of rocky temperate mesophotic ecosystems

Conservation Biology, Volume 38, Issue 1, February 2024.
Abstract The ecology and function of rocky temperate mesophotic ecosystems (TMEs) remain poorly understood globally despite their widespread distribution. They typically occur at 20–150 m (the limit of photosynthesis), and on rocky substratum they support rich benthic communities and mobile fauna.

Consideraciones en torno a las hipótesis alternativas de estacionalidades fijas o variables

Rect@, 2001
