Seasonal variability of copepods and cladocerans in Bahía de los Ángeles (Gulf of California) and importance of Acartia clausi as food for whale sharks

Ciencias Marinas, 2011
Bahía de los Ángeles is located on the Baja Californian coast of the Gulf of California, adjacent to Ballenas Channel. The bay receives a dynamic tidal influence from the channel but is protected by numerous islands.

Improving sightings-derived residency estimation for whale shark aggregations: A novel metric applied to a global data set

Frontiers in Marine Science, 2022
The world’s largest extant fish, the whale shark Rhincodon typus, is one of the most-studied species of sharks globally. The discovery of predictable aggregation sites where these animals gather seasonally or are sighted year-round – most of which are ...

A Comprehensive Reassessment of the Global Illegal Wildlife Trade's Economic Value 全球非法野生动植物贸易经济价值的全面重新评估**

Integrative Conservation, EarlyView.
Through systematic price collection and correction for underreporting and undetected seizures, the global illegal wildlife trade (IWT) is estimated at US$28.4–39.5 billion per year. This finding highlights that previous valuations were underestimates.

A metabolomic approach to health assessment in the whale shark, Rhincodon typus [PDF]

, 2013
Background. No studies have evaluated the biochemistry of whale sharks. The illness of two animals in the collection at Georgia Aquarium provided an opportunity to evaluate the blood chemistry of healthy and unhealthy animals in a search for biomarkers of health in this species. Methods.

The ecological connectivity of whale shark aggregations in the Indian Ocean: a photo-identification approach [PDF]

Royal Society Open Science, 2016
Genetic and modelling studies suggest that seasonal aggregations of whale sharks (Rhincodon typus) at coastal sites in the tropics may be linked by migration.

Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

Journal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...

‘It's not much, but it's honest work’: The status of environmental DNA analyses of fish biodiversity in southern Africa

Journal of Fish Biology, EarlyView.
Abstract Environmental DNA (eDNA) biodiversity surveys have the power to transform the detection of species in natural environments, which is crucial for the conservation and management of freshwater, estuarine and marine environments. Globally, eDNA‐based analyses have increased significantly, with fishes being the most widely studied aquatic ...

Spatial modeling of whale shark protection using the marxan method in Saleh Bay, West Nusa Tenggara [PDF]

BIO Web of Conferences
Saleh Bay is a recurring aggregation area for whale sharks (Rhincodon typus). This study applied the Marxan decision-support tool to identify spatial conservation priorities based on whale shark sighting records and selected environmental and ...

Prospects of multipurpose biomonitoring for fisheries assessment based on environmental nucleic acids

Journal of Fish Biology, EarlyView.
Abstract Methods using environmental nucleic acids have become highly effective for monitoring aquatic biodiversity, with an array of suitable use cases, including metrics for fisheries assessment. Traditional methods for assessing fish populations often rely on invasive techniques with limited spatial and temporal coverage.

Longest recorded trans-Pacific migration of a whale shark (Rhincodon typus) [PDF]

Marine Biodiversity Records, 2018
Les requins-baleines (Rinchodon typus) se trouvent dans les eaux côtières peu profondes et profondes des mers tropicales et tempérées chaudes. Les études génétiques des populations indiquent une connectivité élevée entre les populations, et une métapopulation indo-pacifique a été suggérée avec des migrations potentielles dans certains bassins ...
