Limited global awareness of invasive alien species and little support for their management

Invasive alien species (IAS) are one of the main drivers of global change and can cause a wide range of negative ecological and social impacts. Addressing these impacts requires management actions, which can fail to be effective when not supported by the public. Here, we conducte...

A global mitochondrial genomic atlas illuminates freshwater microeukaryote diversity

Abstract Environmental genomics has transformed our view of the microbial world, yet progress remains largely prokaryote-centric. Among microbial eukaryotes, inconsistent marker choice and limited species-level resolution blunt diversity estimates and hinder cross-study synthesis...

From online traces to upstream surveillance: Large language models uncover the hidden status of non-native freshwater apex predators in China

Biological invasions are often recognised only after ecological damage has become visible in the wild, even though the human-mediated processes that drive introductions may already be underway through private rearing, trade, and release. This gap in upstream surveillance is espec...

Elevation Amplifies Carrier-Type Differences in Nitrogen Cycling and N 2 O Dynamics in Lake Biofilms

Abstract Lake biofilms are microbial habitats for nitrogen transformation, but how carrier type and elevation influence N2O dynamics remains unclear. We examined abiotic- and biotic-carrier biofilms from 12 lakes spanning 4–4272 m using anoxic incubations, 15N tracing, selective...

Trpv4 links environmental temperature to testicular differentiation in hermaphroditic ricefield eel

The ricefield eel ( Monopterus albus ), an economically important aquaculture species in China, is a freshwater teleost fish that exhibits protogynous hermaphroditism. Although progress has been made in understanding the sex determination and differentiation of this species, the...

Misperceptions of charismatic species' conservation status: Zoo visits and virtual exposure shape perceptions of extinction risk

Abstract Biodiversity loss is accelerating globally, yet species are not equally affected, and public perceptions of extinction risk often diverge from scientific assessments. Understanding what shapes public perceptions is critical for effective conservation communication, parti...
