The scale and drivers of marine biodiversity loss are being revealed by the International Union for Conservation Nature (IUCN) Red List assessment process. We present first global reassessment 1,199 species in Class Chondrichthyes-sharks, rays, chimeras. (in 2014) concluded that one-quarter (24%) were threatened. Now, 391 (32.6%) threatened with extinction. When this percentage threat is applied to Data Deficient species, more than one-third (37.5%) chondrichthyans estimated be threatened,...
International trade for luxury products, medicines, and tonics poses a threat to both terrestrial marine wildlife. The demand consumption of gill plates (known as Peng Yu Sai, "Fish Gill Mobulid Ray") from devil manta rays (subfamily Mobulinae, collectively referred mobulids) significant these fishes because their extremely low productivity. has driven an international supplied by largely unmonitored unregulated catches target incidental fisheries around the world. Scientific research,...
Biodiversity loss is a major global challenge and minimizing extinction rates the goal of several multilateral environmental agreements. Policy decisions require comprehensive, spatially explicit information on species’ distributions threats. We present an analysis conservation status 14,669 European terrestrial, freshwater marine species (ca. 10% continental fauna flora), including all vertebrates selected groups invertebrates plants. Our results reveal that 19% are threatened with...
Abstract Understanding the details of local and regional extinctions allows for more efficient allocation conservation activities resources. This involves identifying where populations persist, may still be present, locally extinct. Three threatened angel sharks occur in Eastern Atlantic Mediterranean Sea: Sawback Angelshark (Squatina aculeata), Smoothback oculata), squatina). Population sizes geographic ranges these species have been reduced due to overfishing habitat loss, placing them...
Structural or binary approaches, based on presence‐absence of feeding links, are the most common method assembling food webs and form basis well explored web models. Binary approaches to links often criticized as being less powerful accurate than flow‐based methods. To test this assumption we compared estimates trophic position with stable isotope values nitrogen (δ 15 N). For 366 species from eight marine estuarine (presence‐absence) a subset 127 fish in four further gut content analysis...
Nonselective fishing gears extract a great many small marine species, with limited documentation or assessment of their impacts. Among those seahorses (genus Hippocampus ) are unusual because this genus has been the focus scientific surveys and international trade regulation. Our review published unpublished data sources analyzed on seahorse bycatch for five gear‐type categories 22 countries. The median catch per unit effort across all gear types was 0.96 vessel −1 day . Nonetheless, fleet...
Recent studies on deep-sea sponges have focused mapping contemporary distributions while little work has been done to map historical distributions; can provide valuable information the time frame over which species co-evolved and may insight into reasons for their persistence or decline. Members of sponge family Geodiidae are dominant members assemblages in northwestern Atlantic. They possess unique spicules called sterrasters, undergo transport sediment therefore indicate presence when...
Life‐history variables for three incidentally captured species of seahorse (Kellogg's Hippocampus kelloggi , the hedgehog spinosissimus and three‐spot trimaculatus ) were established using specimens obtained from 33 fisheries landing sites in Peninsular Malaysia. When samples pooled by across peninsula, sex ratios not significantly different unity, height mass relationships significant all species. For two these species, at physical maturity ( H M was smaller than which reproductive activity...
Two seahorse species, Hippocampus spinosissimus and trimaculatus , sampled in east west coastal waters of Peninsular Malaysia, fed mostly on crustacean prey; small caridean shrimps amphipods as adults (both species), copepods larval meroplankton juveniles (for H. only). The similar short relative gut length (~0.4) both species is consistent with a carnivorous diet. Both are considered specialists prey selection, focusing slow-moving epibenthic, hyperbenthic canopy-dwelling crustaceans that...
New records of the Japanese seahorse Hippocampus mohnikei from Cambodia, Malaysia, Thailand and Vietnam, along with recently published studies India Singapore, have greatly expanded known range H. within Southeast Asia. These new reveal novel habitat preferences threats to in region. Although global conservation status is classified as Data Deficient according IUCN Red List Threatened Species, sightings indicate that this species found similar habitats faces other are considered Vulnerable.
Video cameras recorded the diurnal visitation rates of transient (large home range) piscivorous fishes to coral patch reefs in The Bahamas and identified 11 species. Visits by bar jack Caranx ruber , mutton snapper Lutjanus analis yellowtail Ocyurus chrysurus barracuda Sphyraena cero Scomberomorus regalis were sufficiently frequent correlate with a range biophysical factors. Patch‐reef fish abundances varied distance from shore all species except S. seen more frequently inshore. This pattern...
Background. Increased interest in luxury products and Traditional Chinese Medicine, associated with economic growth China, has been linked to depletion of both terrestrial marine wildlife. Among the most rapidly emerging concerns respect these markets is relatively new demand for gill plates, or Peng Yu Sai (“Fish Gills”), from devil manta rays (subfamily Mobulinae). The high value plates drives international trade supplied by largely unmonitored unregulated bycatch target fisheries around...
<h3>Objectives</h3> Molecular classification of endometrial carcinoma (EC) enables consistent tumours and provides valuable prognostic predictive information. Herein we describe molecular subtype distribution histomorphologic correlates in recently diagnosed (2016) ECs from across Canada. <h3>Methods</h3> was performed on representative tumour specimens participating centres. Clinicopathologic, management outcome data were collected (REDCap). <h3>Results</h3> 1453 30 centres have been...
Moored fish aggregating devices (MFADs) are promoted in small-scale fisheries around the world as tools to increase fisher incomes, enhance food security, and ease pressure on degraded inshore fisheries. Despite their growing popularity, biophysical socioeconomic contexts which MFAD implemented - implications of these for fishery success remain poorly understood. Here we develop a framework identifying evaluating factors likely influence outcomes apply it across states insular Caribbean...
Abstract Total allowable catch restrictions (hereafter referred to as quotas) play an important role in maintaining healthy fish stocks. While studies have identified a positive relationship between quota implementation and improved stock status, these methods are subject selection bias quotas typically applied stocks that depleted. We address this challenge using the synthetic control method, which estimates causal effect of on fishing mortality biomass by predicting counterfactual outcome....
