Justice for biodiversity: an X‐curve transformation pathway for a sustainable future

Frontiers in Ecology and the Environment, EarlyView.
Decades of conservation action have failed to stem biodiversity loss, stimulating heated debates over which conservation strategies are the most effective. Do we focus on preserving sufficient wilderness, maintaining services from nature for societal well‐being, or protecting vulnerable socioecologies from injustice?

Rethinking Environmental Impact Assessment for nature positive development

Frontiers in Ecology and the Environment, EarlyView.
Achieving “nature positive” development within existing regulatory frameworks will be challenging. Halting and reversing biodiversity loss requires protection, restoration, and enhancement of ecosystems alongside a fundamental shift in how biodiversity is valued and quantifiable improvements are assessed.

Trophic ecology of benthic fish assemblages in a lowland river in the Brazilian Amazon

, 2019
Studies on the trophic ecology of fish have revealed considerable alimentary plasticity for the majority of ichthyofauna in tropical rivers. This leads to the prediction that diet reflects the availability of food in the environment, namely seasonal ...

Antimicrobial Sensitivity Profile and Resistance Gene Research in Escherichia coli Isolated From Water and Fish From Lagoa da Conceição, Florianópolis, SC, Brazil

Food Safety and Health, EarlyView.
This paper highlights a concerning scenario of environmental contamination by multidrug‐resistant bacteria, underscoring the need for integrated surveillance and control strategies to address antimicrobial resistance in aquatic environments within the context of One Health.

Emergent competition shapes top-down versus bottom-up control in multi-trophic ecosystems.

PLoS Computational Biology
Ecosystems are commonly organized into trophic levels-organisms that occupy the same level in a food chain (e.g., plants, herbivores, carnivores). A fundamental question in theoretical ecology is how the interplay between trophic structure, diversity ...

Experimental reduction of land use increases invertebrate abundance in grasslands

Basic and Applied Ecology
Grasslands are diverse ecosystems that are increasingly threatened by intensive land use. Restoring grasslands by reducing land-use intensity may support insect abundance and diversity, helping to halt insect declines.

The relationship between cellular protein content and selenium accumulation in freshwater microalgae

Integrated Environmental Assessment and Management, EarlyView.
Abstract Variability in the bioconcentration of selenium (Se) by primary producers at the base of the food web results in uncertainty in predictions of bioaccumulation and ecological risk to higher trophic level organisms. Water chemistry, speciation of Se, and periphyton community composition have all been suggested as factors that contribute to ...

Soil‐derived, gut‐dominant generalist bacteria shape the fitness of folivorous larvae

iMeta, EarlyView.
Whether Lepidoptera harbor a conserved core gut microbiome has long remained contentious. Through large‐scale microbiome profiling of folivorous larvae, their host plants, and associated soils across three climatically distinct regions of China, we identify two soil‐derived generalist bacteria, Ralstonia insidiosa and Delftia sp., that colonize 97.92 ...

Half a Century of Per‐ and Polyfluoroalkyl Substances in Northern Gannet Eggs: Impact of Regulations

Journal of Applied Toxicology, EarlyView.
ABSTRACT Per‐ and polyfluoroalkyl substances (PFAS), known as “forever chemicals”, are persistent organic pollutants that have been widely used in the industry across the globe for many decades. Their chemical stability, bioaccumulation, and toxicity pose major environmental and health risks. This study examines temporal trends in the concentrations of
