Multitrophic alpha and beta diversity of lake plankton across Canada

open access: yesOikos, EarlyView.
Anthropogenic environmental changes impact freshwater biodiversity globally. While biodiversity assessments in freshwater environments have traditionally focused on individual groups of organisms or trophic levels, considering patterns of ‘multitrophic biodiversity' across the food web provides a more comprehensive view of anthropogenic impacts and ...

Small changes in climate can profoundly alter the dynamics and ecosystem services of tropical crater lakes. [PDF]

open access: yesPLoS ONE, 2014
African tropical lakes provide vital ecosystem services including food and water to some of the fastest growing human populations, yet they are among the most understudied ecosystems in the world. The consequences of climate change and other stressors on

Aquaculture in tropical Mexican lakes and dams: achievements and perspectives [PDF]

open access: yes, 2000
Mexico, with highly diverse physiography, geology, soils and climate, is a country with a broad mosaic of aquatic ecosystems within 320 watersheds.

A long-term study on crustacean plankton of a shallow tropical lake: the role of invertebrate predation

open access: yes, 2015
The primary factor that governs the size and species composition of zooplankton is still a controversial issue and temperature is considered the main factor responsible for latitudinal differences.

Hunting motivations, behaviour and forest access: Characterising wildlife hunting practices in a multi‐ethnic, forested landscape of Brunei Darussalam, Southeast Asia

open access: yesPeople and Nature, EarlyView.
Abstract Unsustainable hunting practices can alter population dynamics, driving biodiversity declines, which leads to ‘empty forests’. Understanding hunting behaviour, including motivations for hunting and relationships with market drivers, and access to hunting grounds are important to develop affirmative policies to stem biodiversity loss.

Andean drought and glacial retreat tied to Greenland warming during the last glacial period

open access: yesNature Communications, 2020
How the abrupt warming events recorded in Greenland ice cores during the last glacial cycle have influenced the tropical climate is not well known. Here the authors present new lake sediment data from the Peruvian Andes that shows that these events ...

Influences of Lake Malawi on the spatial and diurnal variability of local precipitation [PDF]

open access: yesHydrology and Earth System Sciences, 2019
We investigate how the intensity and spatial distribution of precipitation vary around Lake Malawi on a diurnal timescale, which can be valuable information for water resource management in tropical south-eastern African nations. Using a state-of-the-art

HYDRODYNAMIC INVESTIGATION OF A SHALLOW TROPICAL LAKE ENVIRONMENT (LAGUNA LAKE, PHILIPPINES) AND ASSOCIATED IMPLICATIONS FOR EUTROPHIC VULNERABILITY

open access: yesASEAN Engineering Journal, 2014
In this study, a three-dimensional (3D) hydrodynamic model was developed to investigate the water circulation characteristics of a shallow tropical lake environment (Laguna Lake, Philippines) under varying wind stress, watershed river discharge, and sea ...

More than proteins for empty stomachs: Wild meat in the BaTonga food system

open access: yesPeople 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.

Hydrochemistry, ostracods and diatoms in a deep, tropical, crater lake in Western Mexico

open access: yesJournal of Limnology, 2013
Crater lakes are sensitive to natural and anthropogenic environmental changes and it is important to define and understand their current status in order to evaluate past changes related to climate variability and future ones associated with modern global
