Metagenomic insights into surface sediment microbial community and functional composition along a water-depth gradient in a subtropic deep lake [PDF]

open access: yesFrontiers in Microbiology
Deep lakes play a critical role in global elemental cycling and serve as habitats for diverse microbial communities. However, studies on the effects of lake stratification on microbial composition and functional potential in surface sediments remain ...

Integrating water depth to predict the threshold of collapse and recovery of submerged macrophytes for lakes with large depth gradients [PDF]

open access: yesFrontiers in Plant Science
IntroductionThe nutrient threshold of collapse and recovery of submerged macrophytes have been widely reported for shallow lakes. However, understanding the threshold variation for lakes with water depth (Z) gradients remains limited.MethodsIn this study,

Bill Length of Non‐breeding Shorebirds Influences the Water Depth Preferences for Foraging in the West Coast of India [PDF]

open access: yesEcology and Evolution
Body size, bill length and shape determine foraging techniques, habitat selection and diet among shorebirds. In this study, water depth preferences of different shorebirds with different bill sizes in various habitats including mudflats, mangroves at ...

The Occurrence and Distribution of Benthic Foraminifera in Tropical Waters Along the Strait of Malacca

open access: yesFrontiers in Marine Science, 2021
Foraminifera are shelled single-celled protists that are found in all marine environments. Benthic foraminifera either live in sediments or attach to surfaces on the seafloor. Understanding the distribution and ecological response of benthic foraminifera

Water depth modulates the species richness–biomass relationship in submerged macrophytes

open access: yesFrontiers in Environmental Science, 2023
The effect of biodiversity on ecosystem productivity has been a controversial issue in ecological research. The species richness–productivity relationship is highly variable in natural ecosystems, with a positive relationship being one of the most ...

MAXIMIZATION OF PRODUCTION AND NET INCOME IN AGRO-FOREST SYSTEMS

open access: yesEngenharia Agrícola, 2022
In this study, we present computational procedures to solve problems for the maximization of production and net income from crops or trees in a randomly generated agroforestry system with limited inputs, based on the Logarithmic Barrier Method.
