PHOTOSYNTHETIC EFFICIENCY OF PHYTOPLANKTON IN A TROPICAL MOUNTAIN LAKE
Caldasia, 2006 Minimum (F0), maximum (Fm), and variable (Fv = Fm - F0) fluorescence andphotosynthetic efficiency (Fv/Fm) of phytoplankton were measured for severaldepths and under laboratory conditions during two seasons (June and October of2000) in Lake Guatavita, Colombia.

More than proteins for empty stomachs: Wild meat in the BaTonga food system
People and Nature, EarlyView.Abstract Our paper highlights the limitations of the framework used by many conservation‐focused programmes that incorporate food security objectives. This framework encourages the substitution of wild proteins with domestic proteins by promoting animal farming in communities located near conservation areas.

Limnology of Botos Lake, a tropical crater lake in Costa Rica.
Revista de biologia tropical, 2001 Botos Lake, located at the Poas Volcano complex (Costa Rica) was sampled eight times from 1994 to 1996 for physicochemical conditions of the water column and phytoplanktonic community composition. Depth was measured at fixed intervals in several transects across the lake to determine its main morphometric characteristics.

PLANTS, PEOPLE, PLANET, EarlyView.Banana and plantain are vital for food security and income in West Africa, yet banana bunchy top virus (BBTV) threatens production. This study combined remote sensing, field surveys, modelling and socio‐economic analysis to assess BBTV spread and control strategies in Benin.

Revista de Biología Tropical, 2005 Whether the primary role of bacterioplankton is to act as "remineralizers" of nutrients or as direct nutritional source for higher trophic levels will depend on factors controlling their production and abundance.

PLANTS, PEOPLE, PLANET, EarlyView.Despite growing investment in restoration, weak accountability and poor biodiversity monitoring mean many projects fail to achieve ecological recovery. The Global Biodiversity Standard (TGBS) offers a practical way to ensure that restoration finance delivers measurable gains for nature.

Geophysical Monograph Series, Page 263-304., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Structure and dynamics of phytoplankton in an Amazon lake, Brazil
Revista de Biología Tropical, 2010 Natural lake systems represent important reservoirs for residential water supply, fish production, recreational activities and enjoyment of their natural beauty. Nevertheless, human impacts may affect their health status resulting in degradation and loss

Evaluating anisotropy‐based Monin–Obukhov similarity theory over canopies and complex terrain
Quarterly Journal of the Royal Meteorological Society, EarlyView.This study shows that an anisotropy‐based generalization of Monin–Obukhov surface‐layer scaling (SC23) applies readily across a wide range of atmospheric conditions with variable terrain, canopies, and land‐cover complexity. This work focuses on the scaling of velocity variances for 7 years at the 47 sites in the National Ecological Observation Network
