Decoding Dual Regulatory Layers: Integrating Differential Expression and Alternative Splicing Dynamics in the Evolution of Laryngeal Echolocation Across Chiropteran Lineages

open access: yesIntegrative Zoology, EarlyView.
We integrated short‐read and long‐read RNA‐seq data from cochlear tissues of echolocating and non‐echolocating bats to disentangle transcriptional and post‐transcriptional regulation. Echolocating bats showed neural‐function enrichment among differentially expressed genes, while alternatively spliced genes were linked to epigenetic regulation. Overlaps

Aboriginal whale watching

open access: yes, 2008
[Extract] There are several aboriginal-owned whale-watching ventures in Canada, Australia and New Zealand. These include viewing orca (killer whale) with Village Island Tours (Telegraph Cove, BC), operated since 1989 by Tom Sewid, a Kwakwak'awakw First ...

The current state and future prospects of whale-watching management : with special emphasis on whale-watching in British Columbia, Canada [PDF]

open access: yes, 2008
Commercial whale-watching has become an important aspect of global marine tourism. Rapid expansion during the 1990s has created a yearly US$1 billion industry, in which approximately 10 million people go whale-watching in nearly 90 countries.

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

open access: yesIntegrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

Fishing Activity Affected Odontocete Cetacean Distribution in a Marine Protected Area in the East China Sea

open access: yesIntegrative Zoology, EarlyView.
Spatiotemporal distribution of odontocete cetaceans within China's Jiushan Archipelago National Nature Reserve was investigated. Fishing vessels significantly reduced both cetacean acoustic detections and feeding activity, whereas gillnets selectively suppressed cetacean feeding behavior without affecting overall cetacean detection rates.

Osteological, Biological, and Genetic Consequences of Colonization of Fresh Waters by Marine Cottoid Fishes (Cottidae)

open access: yesIntegrative Zoology, EarlyView.
Lacustrine forms of Triglopsis from North American and European lakes are at different stages of evolution, making them a suitable model for testing hypotheses about evolutionary patterns and rates. An integrative analysis of morphological, genetic, and biological adaptations occurring in lacustrine forms of the genus Triglopsis was carried out.

Evolutionary Mechanisms of Coagulation Factors in Cetaceans During Aquatic Adaptation

open access: yesIntegrative Zoology, EarlyView.
Compared with Bos taurus, T. truncatus showed shorter prothrombin time and thrombin time but prolonged activated partial thromboplastin time, indicating pathway‐specific remodeling of coagulation. Evolutionary analyses identified 18 positively selected genes and accelerated F11 evolution, while functional assays revealed increased coagulation factor ...

Successful 22‐Hour Rescue and Release of a 19.5 M Beached Sperm Whale

open access: yesIntegrative Zoology, EarlyView.
19.5‐m‐long sperm whale was stranded on a mudflat, China on 19 April 2022. A dramatic 22‐hour rescue mission ultimately saved the whale, enabling it to swim back to sea. ABSTRACT Whales, dolphins, and porpoises are important flagship species and play a vital role in maintaining healthy aquatic ecosystems. However, stranded cetaceans are often doomed if

Maximizing eDNA detections of rare marine organisms: A case study of a delphinid species

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Environmental DNA (eDNA) is an emerging tool for surveying marine organisms. Advances in molecular assay designs and bioinformatic methods provide new opportunities for detecting rare species; however, overcoming methodological challenges of rare species detection remains an important obstacle for the widespread deployment of eDNA methods for ...
