Shark depredation and bycatch are a common occurrence at remote Lord Howe Island, New South Wales. This is causing extra mortality of target fish species like yellowtail kingfish, costly loss of gear and catch for fishers and injuries to sharks. We conducted the first study into the resident Galapagos shark population at Lord Howe Island, using acoustic telemetry to map shark home ranges and residency patterns and combining this with vessel tracking to identify key areas where fishers and sharks interact more frequently. Highest overlaps occurred at productive shelf edges and a fish disposal site. This spatial information was combined with local fisher knowledge to develop a set of best-practice guidelines for assisting fishers to mitigate the occurrence of shark interactions, providing positive benefits for the marine environment, fishers and sharks. This work was supported by Parks Australia, The University of Western Australia, NSW DPI and the IMOS Animal Tracking Facility. You can read the full open-access paper here: https://lnkd.in/gR_YMWMR

A recent potential wolf sighting in Nevada had wildlife enthusiasts buzzing, but the mystery has now been solved through good old-fashioned science! Here are the fascinating details: 📸 In March, a helicopter crew spotted 3 wolf-like animals roaming near Merritt Mountain, sparking an investigation by the Nevada Department of Wildlife. 🧫 Biologists collected hair, fecal, and urine samples believed to be from the creatures for DNA testing at two independent labs. 🚨 The results? It was 99.9% certain that the "wolves" were actually coyotes, common residents of Nevada! 🐺 While disappointing for wolf spotters, the case highlights the importance of accurate species identification to protect ecosystems. This saga reminds us that nature often holds surprises, and sometimes, first impressions can be deceiving. Kudos to the wildlife experts for their diligent investigative work! 👏 Have you ever mistaken one animal for another in the wild?

The Exocoetidae are a family of marine ray-finned fish in the order Beloniformes, known colloquially as 'flying fish'. About 64 species are grouped in seven genera. Flying fish can make powerful, self-propelled leaps out of the water where their long wing-like fins enable gliding for considerable distances above the water's surface. The main reason for this behavior is thought to be to escape from underwater predators. 1. "How and why do flying fish fly?" Reviews in Fish Biology and Fisheries. 4 (2): 184–214. 2.

Horizon Scanning & Hotspot Analysis for Invasive Species Early Detection and Rapid Response Webinar Mon April 29th – 3:00-4:30 pm ET Join us for a webinar that explores horizon scanning (what to look for) and hotspot analysis (where to look) to inform early detection and rapid response (EDRR) for invasive species. The webinar will feature presenters from the US Geological Survey and the US Fish and Wildlife Service. They will share the latest information on global and regional horizon scans, watchlists, and hotspot analysis tools for both aquatic and terrestrial species. The webinar will also feature breakout sessions to further explore this topic and learn about participants’ perspectives, with a focus on how a new hotspot analysis tool in development for invasive animals can best meet needs.   Register here: https://lnkd.in/ehvFymKc #invasivespecies #edrr #earlydetection #horizonscan #hotspotanalysis #invasive #invasiveplants #invasivefish #invasivecarp #webinar #professionaldevelopment

Animals Everywhere: Exploring Habitats In the fascinating world of science, one of the most exciting topics to explore is how animals live and thrive in different environments across the globe. From the freezing polar regions to the steamy tropical rainforests, animals are found everywhere, each uniquely adapted to its habitat. In this article, we'll dive into the concept of animal habitats and explore the amazing adaptations that allow animals to survive and flourish in their surroundings. What Is a Habitat? A habitat is the natural environment where an animal lives. It provides everything the animal needs to survive: food, water, shelter, and space. Habitats can vary widely in temperature, moisture, and the types of plants and animals that live there. The main types of habitats include: Forests: Forests are dense with trees and vegetation. They can be tropical, temperate, or boreal, each offering a unique environment. Animals like monkeys, birds, and insects are commonly found in forests, where they depend on trees for food and shelter. Deserts: Deserts are dry, with little rainfall and extreme temperatures. Animals such as camels, lizards, and snakes have adapted to conserve water and survive in the intense heat. Grasslands: Grasslands, also known as savannas or prairies, are open areas with few trees. They are home to herbivores like zebras and antelopes, as well as predators like lions and cheetahs that hunt in the vast, open spaces. Oceans: Oceans cover most of the Earth and provide a habitat for a wide range of marine life, from tiny plankton to massive whales. Fish, sharks, dolphins, and sea turtles are just a few examples of ocean dwellers. Polar Regions: The Arctic and Antarctic are cold, icy regions where only the hardiest of animals, like polar bears, penguins, and seals, can survive. These animals have special adaptations to stay warm in the freezing temperatures. Wetlands: Wetlands are areas where water covers the soil, like swamps and marshes. Frogs, alligators, and many bird species thrive in these water-rich environments.

Bighead carp are voracious eaters and are capable of wiping out the base of an aquatic food chain. Silver carp routinely leap up to nine feet out of the water when startled by boat motors, which can cause serious injuries to boaters. Both are beginning to invade Minnesota waters. Minnesota’s best defense at keeping these invasive species at bay: a single, strategically placed wall of vibrating bubbles known as a bioacoustic fish fence, or BAFF, which can be placed in navigation locks. 🎣 Learn more about the work U of M researchers are doing by visiting z.umn.edu/9mul Peter W.
