Devil’s hole pupfish might be functionally extinct (they recently added dozens of captive bred individuals to the 20 wild individuals left). www.npr.org/2026/05/07/n...

As federal scientists faced turmoil, the Devils Hole pupfish reached a crisis point

The Devils hole pupfish lives in just one spot in Death Valley. Wildlife officials have managed this iconic fish for decades, and last spring, just as the Trump administration was laying off all kinds...

@govnl.bsky.social has turned down the proposed South Coast Fjords Marine Conservation Area. This is a huge drawback for Canada's #30by30 conservation target. MCAs benefit both the ecosystem AND the economy, rather than hindering them. More info here: lnkd.in/eZeqVfv8 #MarineConservation #MCA

N.L. terminates MOU that could have seen south coast fjords become conservation area | CBC News

The Progressive Conservative government is tearing up a memorandum of understanding that could have created a National Marine Conservation Area on the south coast of Newfoundland.

Colossal Bioscience did not revive dire wolves, despite a sensationalist Time Magazine cover story. Making genetically modified animals that are cosplaying as extinct species is not de-extinction.

Riley Black 🏳️‍⚧️ 🦖@restingdinoface.bsky.social · 2y ago

Dire wolves were not close relatives of gray wolves. They last shared a common ancestor more than 5 million years ago. What Colossal has done is make something new and slapped a dire wolf sticker on it, as if an organism equals a hypothetical genome.

One of my first internships was with ME Sea Grant (where I learned R!), and I wouldn't be where I am now without that opportunity. This is devastating for the future of coastal/ marine management in Maine.

Emily Knight@emilyknight.bsky.social · 2y ago

Maine Sea Grant changed my life when they gave me the Knauss Fellowship on Capitol Hill. I owe them my career. How will young scientist looking to use our skills to serve the public find opportunities going forward? We are killing ourselves. www.pressherald.com/2025/03/01/m...

Merry #fishmas! Along with being adorable, Lumpsuckers are used in Atlantic Salmon #aquaculture to eat sea lice, resulting in interesting genetic differences between wild and domestic populations. #25daysOfFishmas

We have reached day 25 of #25daysoffishmas and we draw to a close with my subject of study, Cyclopterus lumpus, which actually lacks a full common name and is simply called "lumpsucker". This species really stands out from the rest of the family, in terms of appearance, size and behaviour.

Atlantic #salmon, brown #trout and their hybrids can be difficult to distinguish, especially at early life stages. This new DNA-based method can be used to screen lots of individuals to verify the species or detect hybrids! 🧪🐟 With a low-cost DNA extraction, it is less than 1 euro / sample.

Fast and cost‐efficient species identification of Atlantic salmon (Salmo salar L.), brown trout (Salmo trutta), and their hybrids using a single SNP marker

A workflow for developing a cost- and time-efficient, single nucleotide polymorphism (SNP)-based assay for species and hybrid identification is described. In a reference set (n = 46), the developed a....

The Golden Redhorse is one of my favorites from biodiversity surveys on the Buffalo River, AR! #25DaysOfFishmas

On the 5th day of #Fishmas, my true love gave to me…5 Gold Rings? Boring. Up your gift-giving game instead this season by giving your love the Golden Redhorse (Moxostoma erythrurum), a fish who - despite being part of the sucker family (Catostomidae)- definitely does not suck 🍭 #25DaysofFishmas
