Recent changes in molluscan species diversity of a large tropical lake (Lago de Peten, Guatemala)1 [PDF]
Limnology and Oceanography, 1976 The relative and absolute shifts in abundance of five species of freshwater gastropods appear to reflect widespread changes in the drainage basin around Lago de Peten. Fluctuations in the number of shells deposited in 3.7 m of lake sediments are not directly correlated with changes in preserved organic matter or major cations (calcium, magnesium, and ...

Revista de Biología Tropical, 2017 Functional morphology corresponds to adaptive responses to changes in the environment. In phytoplankton, traits such as the development of mucilage, oil vesicles, filaments and variation in the surface/volume ratio, allow algae to deal with sedimentation, optimizing light and nutrient uptake.

Bio-Research, 2021 Ologe and Badagry Lagoons are important tropical lagoons in Lagos, Nigeria. The water quality and heavy metal concentration were studied for a period of 2 years (Aug. 2016 to Jul. 2018) using standard methods. The least temperature obtained was 28.70±0.05 °C in Ologe Lagoon during the wet season and the maximum recorded was 29.41±0.08 in in Badagry ...

Nitrógeno: elemento limitante para el crecimiento fitoplanctónico en un lago oligotrófico tropical [PDF]
, 2008 "El presente estudio tuvo como propósito evaluar si las concentraciones naturales de fósforo y nitrógeno limitaban la biomasa fitoplanctónica en el Lago Alchichica. Se aplicaron tratamientos de enriquecimiento con nitrógeno, fósforoy nitrógeno + fósforo durante las dos etapas características de la hidrodinámica del lago: estratificación y mezcla.Se dio
