threatened with extinction, resulting in a sampled RLI of 0.914 for all species, 0.968 in marine and 0.862 in freshwater ecosystems. Our sample showed fishing as the principal threat for marine species, and pollution by agricultural and forestry effluents for freshwater fishes. The sampled list provides a robust representation for tracking trends i...

Global biodiversitytargets require us to identify species at risk of extinction and quantify status and trends of biodiversity. The Red List Index (RLI) tracks trends in the conservation status of entire species groups over time by monitoring changes in categories assigned to species. Here, we calculate this index for the world’s fishes in 2010, us...
Article
Oil and gas extraction activities occur across the globe, yet species-specific toxicological information on the biological and ecological impacts of exposure to petrochemicals is lacking for the vast majority of marine species. To help prioritize species for recovery, mitigation, and conservation in light of significant toxicological data gaps, a t...

Increasing rates of Anthropocene biodiversity extinctions suggest a possible sixth mass extinction event. Conservation planners are seeking effective ways to protect species, hotspots of biodiversity, and dynamic ecosystems to reduce and eventually eliminate the degradation and loss of diversity at the scale of genes, species, and ecosystems. While...

The use of high-throughput sequencing technologies to produce genome-scale datasets was expected to settle some long-standing controversies across the Tree of Life, particularly in areas where short branches occur at deep timescales. Instead, these datasets have often yielded many well-supported but conflicting topologies, and highly variable gene-...

Understanding the extinction risk of taxonomic groups increases our ability to prioritize efforts to address biodiversity loss. Over 400 species of herrings, shads, sardines, anchovies, menhadens, and relatives belong to the Order Clupeiformes and include many of the most important forage fishes. These small, schooling fishes are ecologically, econ...

Repeatable, convergent outcomes are prima facie evidence for determinism in evolutionary processes. Among fishes, well-known examples include microevolutionary habitat transitions into the water column, where freshwater populations (e.g., sticklebacks, cichlids, and whitefishes) recurrently diverge toward slender-bodied pelagic forms and deep-bodie...

A fundamental understanding of the impact of petrochemicals and other stressors on marine biodiversity is critical for effective management, restoration, recovery, and mitigation initiatives. As species-specific information on levels of petrochemical exposure and toxicological response are lacking for the majority of marine species, a trait-based a...

We reviewed the status of the Mottled Rabbitfish (Siganus fuscescens Houttuyn, 1782) as a major fishery product in Negros Oriental, including threats from microplastic pollution and overfishing. This species is often marketed as either fresh or dried “danggit”. Out of a total of 300 fish samples from four areas in Negros Oriental province, 91 (30%)...

The Mekong River is a vital fisheries resource supporting millions of people in mainland Southeast Asia. However, numerous threats have the potential to negatively impact fish populations in this region including overfishing, pollution, climate change and increased urban, agriculture and upstream hydropower development. Although a few studies have...

An understanding of the genetic composition of populations across management boundaries is vital to developing successful strategies for sustaining biodiversity and food resources. This is especially important in ecosystems where habitat fragmentation has altered baseline patterns of gene flow, dividing natural populations into smaller sub-populati...

A new species of the genus Acropoma, A. arafurensis sp. nov., is described based on two specimens (57.3–76.2 mm standard length: SL) collected from the Arafura Sea. The present species is distinguished from other congeners by a combination of the following characters: luminous gland U-shaped extending from throat to posterior tip of pectoral fin; l...

Aim Mayr's central‐peripheral population model (CCPM) describes the marked differences between central and peripheral populations in genetic diversity, gene flow, and census size. When isolation leads to genetic divergence, these peripheral populations have high evolutionary value and can influence biogeographic patterns. In tropical marine species...

Puffers are biologically and ecologically fascinating fishes best known for their unique morphology and arsenal of defenses including inflation and bioaccumulation of deadly neurotoxins. These fishes are also commercially, culturally, and ecologically important in many regions. One-hundred-and-fifty-one species of marine puffers were assessed again...

Europe has a long tradition of exploiting marine fishes and is promoting marine economic activity through its Blue Growth strategy. This increase in anthropogenic pressure, along with climate change, threatens the biodiversity of fishes and food security. Here, we examine the conservation status of 1,020 species of European marine fishes and identi...

In the Persian/Arabian Gulf, there has been extensive coral habitat degradation and loss because of coastal development and climate change. Fishes dependent on this habitat for survival are of particular concern for conservation. Coral-dependent fishes in the Persian/Arabian Gulf were identified using primary literature and expert opinion. Of the m...

In the Gulf, multiple human impacts and recurrent bleaching events have resulted in serious declines of coral assemblages , particularly in near-shore areas. However, the degree to which the extinction risk of coral-dependent fishes is impacted by these coral declines has been uncertain. Using primary literature and expert knowledge, coral-dependen...

About 50 species of elasmobranchs and 460 species of bony fishes are currently known from the Arabian Gulf. They are key components of the region’s marine biodiversity, contributing to ecosystem functions and services, such as food security. Addressing natural and human-induced threats and the absence of adequate species-specific information, bony...

Percomorphs are a large and diverse group of spiny-finned fishes that have come to be known as the "bush at the top" due to their persistent lack of phylogenetic resolution. Recently, the broader E-uteleost Tree of Life Project (EToL) inferred a well-supported phylogenetic hypothesis that groups the diversity of percomorphs into nine well-supported...

Coral reefs within the Coral Triangle (CT) are home to the greatest marine diversity on the globe and are an important supplier of marine resources to densely populated coastal regions. Many coral reefs within the CT and around the world are under threat from over-exploitation. Marine protected areas (MPAs) have been proven to be effective tools in...
