Tropical Lakes May Emit More Methane

open access: diamondEos, 2021
Fresh waters are one of the primary sources of natural methane emissions, but methane dynamics in tropical lakes are not as well understood as those in more temperate regions.

The methane-oxidizing microbial communities of three maar lakes in tropical monsoon Asia [PDF]

open access: goldFrontiers in Microbiology
Methane-oxidizing bacteria (MOB) is a group of planktonic microorganisms that use methane as their primary source of cellular energy. For tropical lakes in monsoon Asia, there is currently a knowledge gap on MOB community diversity and the factors ...

Identification of aquatic consumer trophic pathways in four volcanic tropical lakes using fatty acid biomarkers

open access: yesJournal of Limnology, 2022
Food web studies rely heavily on the use of traditional gut content analysis or the fairly popular stable isotope analysis rather than fatty acid analysis (FAA) despite its straightforward process, and ability to identify and characterize more diverse ...

Bottom Sediment Characteristics of a Tropical Lake: Lake Tana, Ethiopia [PDF]

open access: yesHydrology, 2020
Sediment concentration of rivers in developing countries has been increasing greatly over the last 50 years due to the conversion of forest to continuously cultivated land with the increasing population. Few studies have addressed its effect on sedimentation and water quality of the lakes by analyzing bottom sediment characteristics. In this study, the

Effects of submerged vegetation on water clarity across climates [PDF]

open access: yes, 2009
A positive feedback between submerged vegetation and water clarity forms the backbone of the alternative state theory in shallow lakes. The water clearing effect of aquatic vegetation may be caused by different physical, chemical, and biological ...

Large CO2 disequilibria in tropical lakes [PDF]

open access: yesGlobal Biogeochemical Cycles, 2009
On the basis of a broad compilation of data on pCO2 in surface waters, we show tropical lakes to be, on average, far more supersaturated and variable in CO2 (geometric mean ± SE pCO2 = 1804 ± 35 μatm) than temperate lakes (1070 ± 6 μatm). There was a significant negative relationship between pCO2 and latitude, resulting in an average decrease of pCO2 ...

Benthic macroinvertebrate community diversity of Montebello Lakes, Chiapas

open access: yesRevista Mexicana de Biodiversidad, 2019
Benthic macroinvertebrate community biodiversity of tropical lakes has been rarely addressed. The present study recognizes the taxonomic diversity of the deep benthic macroinvertebrate communities of 18 lakes of the Protected Natural Area "Lagunas de ...

Linking Biogeochemical and Hydrodynamic Processes to Model Methane Fluxes in Shallow, Tropical Floodplain Lakes

open access: yesJournal of Advances in Modeling Earth Systems, 2023
Floodplains lakes are abundant in the Amazon basin and are important methane sources to the atmosphere. Existing biogeochemical models require modifications and inclusion of hydrodynamic processes operative in shallow, warm waters to be applied to these ...

Perspectives on utilization of community based health information systems in Western Kenya

open access: yesThe Pan African Medical Journal, 2017
INTRODUCTION: Health Information Systems (HIS) are considered fundamental for the efficient delivery of high quality health care. However, a large number of legal and practical constraints influence the design and introduction of such systems.
