Broad‐range necrophytophagy in the flagellate Orciraptor agilis (Viridiraptoridae, Cercozoa) and the underappreciated role of scavenging among protists

open access: yesJournal of Eukaryotic Microbiology, Volume 72, Issue 2, March/April 2025.
Abstract Protists show diverse lifestyles and fulfill important ecological roles as primary producers, predators, symbionts, and parasites. The degradation of dead microbial biomass, instead, is mainly attributed to bacteria and fungi, while necrophagy by protists remains poorly recognized.

Current Status of Hilsa (Tenualosa ilisha) Fisheries in Bangladesh and Implications for Future Research and Development

open access: yesAquaculture, Fish and Fisheries, Volume 5, Issue 1, February 2025.
The hilsa shad (Tenualosa ilisha) is the single largest wild‐fish species in Bangladesh. Approximately 2% of the Bangladeshi population is engaged in hilsa fishing, contributing 1% to the national gross product. Yet, there are several knowledge gaps in hilsa fisheries. In this article, we conducted a systematic review and meta‐analysis of literature to

Naturalized knowledge‐first and the epistemology of groups

open access: yesPhilosophy and Phenomenological Research, Volume 109, Issue 3, Page 856-873, November 2024.
Abstract This paper commences by making a case for a naturalized approach to knowledge‐first epistemology. On this basis it then goes on to describe and defend a naturalized, functionalist account of group knowledge. It then contrasts this with Jennifer Lackey's (2021) account of the epistemological status of groups.

Inclusion of near‐threatened micronutrient‐rich small indigenous species (SIS) dhela (Osteobrama cotio) in pond aquaculture

open access: yesAquaculture, Fish and Fisheries, Volume 4, Issue 3, June 2024.
This study investigated the culture suitability of dhela fish in polyculture with carp species in pond aquaculture systems. Results showed that including dhela in polyculture with carp species did not affect total production but significantly increased net profit and benefit–cost ratio compared to systems without dhela. This suggests that incorporating
