Tropical forest birds after 20 years of the establishment of a reservoir: Extinction, colonization, and recolonization events

Global Ecology and Conservation, 2023
Reservoirs are fundamental for human well-being but can cause landscape changes (e.g., habitat fragmentation and loss), altering biodiversity and ecosystem services.

Empirical food webs of 12 tropical reservoirs in Singapore [PDF]

Biodiversity Data Journal, 2022
Food webs summarise trophic interactions of the biotic components within an ecosystem, which can influence nutrient dynamics and energy flows, ultimately affecting ecosystem functions and services. Food webs represent the hypothesised trophic links between predators and prey and can be presented as empirical food webs, in which the relative strength ...

Improved fisheries productivity and management in tropical reservoirs

, 2009
The main objective of this 3.5 year project was to increase the productivity of reservoir fisheries and provide sustainable livelihoods to the rural poor through a series of interventions in tropical reservoirs. The main project activities focused on two reservoirs in the Indo-Gangetic basin (Dahob in Madhya Pradesh, and Pahuj in Uttar Pradesh, both in
