Seasonal differences and potential biological drivers of the methane paradox in two peri‐Alpine lakes

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 3, May 2026.
Abstract Seasonal variations and the biological drivers underlying the methane paradox in freshwater lakes are poorly understood. Here, we investigated the relationship between subsurface methane inventories and phytoplankton in two peri‐Alpine lakes across different seasons.

Life after death in the pelagic: Non‐predatory zooplankton mortality and the “ghost carbon pump”

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 3, May 2026.
Abstract The biological carbon pump is traditionally framed as a trophically mediated process in which zooplankton mortality is attributed mainly to predation, routing carbon through fecal pellets and higher trophic levels before export. Increasing evidence, however, shows that nonpredatory mortality—caused by different environmental stressors—accounts

Bacteriological Study of the Marine Water in the Coastal of the North Sulawesi Province, Indonesia

open access: yesMakara Seri Sains, 2006
The main objective of this research was to study the marine bacteriology of the coast of North Sulawesi. The study was accomplished by calculating the abundance of coliform, heterotrophic, and pathogenic bacteria, and analyzing the coexistence ...

Ecosystem size reverses the effect of the spatial coupling between autotrophic and heterotrophic ecosystems

open access: yesOikos, Volume 2026, Issue 5, May 2026.
The flow of non‐living resources between autotrophic and heterotrophic ecosystems can impact their ecosystem function. However, ecosystem size is similarly known to influence ecological properties and it is uncertain how the size of coupled ecosystems mediates the effect of resource flows.

Surveying Denitrification Efficacy in Up-Flow Packed Bed Bioreactor Operated under Heterotrophic Condition Using Autotrophic Bacteria

open access: yesJournal of Environmental Health and Sustainable Development, 2019
Introduction: The biological denitrification process is an interesting cost-effective technique to remove nitrate from water supplies. Acetic acid can be used as a carbon source in this process, but its consumption rate is a critical issue and, in some ...

Agroforestry and enhanced rock weathering: A dual strategy for sustainable cacao

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 3, Page 843-860, May 2026.
Cacao production is both economically vital and environmentally intensive, presenting a major sustainability challenge as a crop largely cultivated by smallholder farmers in climate‐vulnerable regions. This review synthesises evidence that integrating agroforestry with enhanced rock weathering (EW) may significantly reduce emissions from cacao ...
