As climate change reduces landscape-scale habitat availability for insects that colonize ephemeral wetlands, population-level shifts in large branchiopods will likely further shift ephemeral wetland ecosystem function from its historic state, which may have large impacts for migrating birds

Insect colonization didn't change which large branchiopod taxa were present, but it did affect their body size, abundance, and reproductive timing (and did so differently across different taxa!).

New 🦐 paper out in Hydrobiologia (with one of my faves @bugginbusch.bsky.social )! We asked: how do resistant ephemeral wetland communities change when insects can't colonize? Short answer is: the species list stays the same, but the populations look different!

πŸ—£οΈ MAJOR ANNOUNCEMENT: Over 80% of our nation’s 4.4M miles of rivers aren’t adequately protected!

Our brand new peer-reviewed research with Conservation Science Partners published in Nature Sustainability shows just how vulnerable our rivers are.

Over the holidays, every single national wildlife refuge, plus some fish hatcheries and marine monuments were directed to conduct a system-wide review. Outrageous deadline of Jan 5 functionally eliminates public input & tribal consultation.

SFS Response Letter on Changes to Waters of the U.S. Definition | Society for Freshwater Science December 30, 2025 β€” The Society for Freshwater Science (SFS) today released a letter outlining changes to the Waters of the U.S. (WOTUS) definition and our response.

The EPA has announced changes to the definition of Waters of the U.S. that leave critical systems supporting drinking water, floodwater storage, and biodiversity unprotected. Public comments on the changes are open until January 5, 2026.

The Trump administration just unveiled a plan to significantly narrow which bodies of water qualify for protection under the Clean Water Act. They proposed a new definition of what counts as a β€œwater of the United States,” a change that would

dramatically reduce which waterways fall under federal pollution safeguards. Under the proposal, groundwater would be excluded entirely, and interstate waters would no longer receive automatic protection.

EPA & Army Corps Unveil Clear, Durable WOTUS Proposal | US EPA EPA Administrator Lee Zeldin, and Assistant Secretary of the Army for Civil Works Adam Telle, today announced a proposed rule that would establish a clear, durable, common-sense definition of β€œwaters ...

The rule also removes protections for ephemeral streams (waterways that flow only after rain or snow) despite their importance to downstream water quality. In short, this proposal rolls back long-standing protections and leaves millions of acres of waterways more vulnerable to pollution.

Surveying wildlife in a pond with water reeds, amidst farmland, trees, hills, woods in distance.

Often overlooked, small water bodies - streams, damp ditches, small bogs, ponds - support more rare species compared with larger habitats while high-quality ponds support about 2/3 of all freshwater plant + animal species in a landscape.

Hundreds of Alligator Alcatraz detainees drop off the grid after leaving site As of the end of August, the whereabouts of two-thirds of more than 1,800 men detained at Alligator Alcatraz during the month of July could not be determined by the Miami Herald.

More than 1800 detainees are missing after the closure of Alligator Alcatraz. Their families and lawyers can’t find them and they’ve vanished from the ICE database. Feels like this should be a much bigger story www.miamiherald.com/news/local/i...

Energy chief suggests Trump administration is altering previously published climate reports | CNN Wright said the Trump administration is updating the National Climate Assessments that have been previously published, which the administration recently removed from government websites.

The Trump administration has deleted all previous National #Climate Assessments from government websites and fired the scientists working on the next report. Now they say they're going to rewrite the previous ones.
This is scientific sabotage and a rewriting of history.
