Delfines de río: una expedición pionera para una especie única

Un equipo de biólogos colombianos y bolivianos expertos en delfines de río, navegaron durante cinco días el río Itenez- Guaporé en la primera expedición dentro de un área protegida para estimar las poblaciones del bufeo boliviano, ver su estado de conservación y posibles amenazas. La iniciativa es liderada por la Fundación Omacha, WWF con el apoyo de Faunagua y el Parque Noel Kempff Mercado. La expedición es parte del Programa Conservación de Delfines de río de Suramérica.

Un equipo de investigadores expertos en delfines de río, conformado por biólogos colombianos y bolivianos, participó de la primera expedición para estimar las poblaciones del bufeo boliviano, ver su estado de conservación y posibles amenazas en el Parque Nacional Noel Kempff Mercado. Navegaron por el río Itenez-Guaporé. La investigación, liderada por la Fundación Omacha, WWF con el apoyo de Faunagua y el Parque Nacional Noel Kempff Mercado, se realizó entre el 2 y 6 de junio como parte de una actividad del Programa Conservación de Delfines de río de Suramérica.

Minambiente emite Directiva Ministerial por alerta de pesca ilegal de mamíferos acuáticos

Bogotá, D.C. 23 de febrero 2017. (MADS). Para prevenir futuros hechos que atenten contra la fauna especialmente, los mamíferos acuáticos amenazados, el Ministerio de Ambiente emitió una Directiva Ministerial que pone en alerta a las Corporaciones Autónomas Regionales con jurisdicción en la Orinoquia, a propósito de la muerte de dos delfines rosados en la desembocadura del río Cravo Sur, en Orocué.

Las reinas del río

Cinco siglos después, al Orinoco le llegó la maldición de El Dorado. Hasta lo profundo de la Guaina, en una zona vedada para el Estado, se adentran cientos de indígenas y mineros de Ecuador, Brasil, Perú o Colombia, que buscan oro, con el agua al cuello, arriesgándose a que se los trague La Manigua o se los lleve el río. Escarban ese caudal efímero dentro del mayor tesoro de biodiversidad, en una selva que alberga, tal vez, uno de los últimos paraísos perdidos del planeta: la estrella fluvial del Inírida.

Good News For India’s Blind River Dolphins

The “My Ganga, My Dolphin” campaign, conducted by the World Wildlife Foundation (WWF) with the help of local fishing communities, has successfully surveyed a 3,350-kilometre stretch of India’s Ganga River. It took 6,000 hours and involved 21 teams, but in the end 1,263 of the endangered dolphins were found – nearly twice the number reached in previous counts.

Fossil Specimen Reveals a New Species of Ancient River Dolphin to Smithsonian Scientists

Smithsonian scientists and colleagues have discovered a new genus and species of river dolphin that has long been extinct. They made the discovery after carefully examining fossil fragments from Panama. The fossil fragments also shed new light on the evolution of today’s freshwater river dolphin species. The team’s research was published Sept. 1 in the scientific journal Peer J.


First New Species of River Dolphin Discovered in a Century

River dolphins (also known as botos) are among the rarest, and most endangered, dolphins in the world. Three of the four known species are listed as “threatened” by the International Union for Conservation of Nature (IUCN). The discovery of a wholly new species—the first such find in a century—is thus exciting news for biologists and conservation officials.

Two blind dolphins found dead in River Indus

The dead dolphins were reported to be floating near different gates of the Sukkar Barrage for hours. The officials of Wildlife Department reached the spot but left without pulling the dolphins out of the river. Local residents turned up in huge numbers to get a glimpse of the dead fish. Deputy Conservator of Wildlife Department Taj Muhammad said that an investigative committee has been formed to look into the matter.

Saving the seas: smarter hooks and nets

Last year, fish consumption reached a global annual average of 37.5 pounds per person. Meanwhile, cod and bluefin-tuna populations have collapsed, and animals ranging from whales to turtles have been added to the Endangered Species Act. Our voracious appetite isn’t the only problem. Fishermen catch a lot of things unintentionally, in what Tim Werner, director of the New England Aquarium’s Marine Conservation Engineering program, calls the “collateral damage” of commercial fishing: bycatch.

Up the Amazon with a paddle

Pink river dolphins arch gracefully through the delicate waves as a congregation of lumpy yellow-eyed caimans glide past in menacing silence. Overhead, what sounds like thousands of howler monkeys roar in a spine-tingling cacophony, while enormous slouching sloths peer languorously from the treetops.

This Ganges dolphin was found floating dead in the Arial Khan river. Locals believe the endangered species died of starvation. Photo: STAR. One of a small pod of Ganges River dolphins that was stranded in the Arial Khan river allegedly died of starvation although the Department of Fisheries (DoF) and locals took initiative to save them. The death of the dolphin came as a shock to the locals, especially to the school-goers. Hundreds of locals including children came to see it.
