Feeding ecology of Australian Christmas beetles (Coleoptera: Scarabaeidae: Rutelinae): Implications for conservation and habitat management

open access: yesAustral Entomology, Volume 65, Issue 2, May 2026.
Abstract Christmas beetles (subfamily Rutelinae, genera Anoplognathus, Calloodes and Repsimus) are an ecologically important and culturally significant group of Australian scarabs, known for their striking appearance and seasonal mass emergences. Over the last decade, anecdotal reports suggest widespread population declines, raising concerns about ...

Size‐based regulation and water quality: Evidence from the Iowa hog industry

open access: yesAmerican Journal of Agricultural Economics, Volume 108, Issue 3, Page 829-855, May 2026.
Abstract The growing prevalence of animal feeding operations (AFOs) in the United States raises concerns among the public and regulators about their impact on local environmental quality. By linking historical regulatory records of AFOs in Iowa to downstream surface water pollution monitors, this paper studies the effects of the 2003 Clean Water Act ...

Optimal timing and rate of nitrogen fertilizer use: An integrated network technology approach

open access: yesAmerican Journal of Agricultural Economics, Volume 108, Issue 3, Page 856-873, May 2026.
Abstract Both the rate and timing of crop fertilizer application play an important role in agricultural productivity. However, inefficient fertilizer use can significantly increase production costs, water pollution, and greenhouse gas emissions. To capture both the spatial heterogeneity and dynamic nature of this problem, we develop a multi‐stage ...

Biological Degradation of Phthalates: From Bioremediation to Plastic Waste Valorization

open access: yesChemSusChem, Volume 19, Issue 7, 14 April 2026.
Phthalic acid isomers play a key role in the plastics industry, but pose significant environmental and health concerns. This review explores the microbial biodegradation of phthalates and their esters, focusing on bacterial enzymes, catabolic pathways, and cellular uptake mechanisms of phthalates.

Impact of Feeding Strategies on Trophic Dynamics, Growth Performance and Sustainability of Nile Tilapia in Semi‐Intensive Aquaculture Systems

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Feed costs and limited knowledge of feeding strategies are a major constraint to the sustainability of semi‐intensive Nile tilapia aquaculture systems in sub‐Saharan Africa. In semi‐intensive systems, Nile tilapia (Oreochromis niloticus) utilizes natural pond production and supplemental feed, but their relative contributions to growth remain ...
