Pollinator decline has captured global attention, but another plant-animal mutualism is quietly unraveling.

Our new Nature Reviews Biodiversity article synthesizes global evidence on seed disperser decline and what it means for plant biodiversity, ecosystem recovery, and climate adaptation. 🧵
Drivers and impacts of global seed disperser decline
Nature Reviews Biodiversity - Many plants rely on animals to disperse their seeds, but some groups of these seed-dispersing animals are facing severe declines. This Review summarizes evidence of...

Since we are still talking about interactions, I worked with some ecologists a couple of years ago on measurement scale, interactions and interpretation issues. I think some problems arise from failure to distinguish prediction from inference, a chronic problem in ecology imo doi.org/10.1111/brv....
Three common inferential errors when investigating context dependence in ecology. Consider a test of context dependence in its most basic form: a 2 × 2 factorial experiment, measuring an ecological response Y, to the crossing of factors X and Z, each with two levels. The analyst fits a statistical model with an interaction term to the data: Y ~ X + Z + X × Z, to test for and quantify context dependence. Three inferential errors are possible when the measurement scale or symmetry of the interaction are overlooked: detection and magnitude (Type D), sign (Type S) and misidentification of underlying processes (Type A).

I decided to start a #thread 🧵 of stories about legal residents and tourists being (illegally) arrested, detained and/or deported by the Trump regime. I'll only post stories from serious sources, as rumors and conspiracies are really not needed in this authoritarian moment.

Probably one of the most productive things you could be doing this week as a scientist in the US. Your science won't matter when narcissistic demagogues dismantle the institutional scaffolding of scientific progress.

NOAA's #GreatLakes Environmental Research Lab will be taking an "indefinite hiatus" from communications due to staff cuts. GLERL communicates critical weekly updates about the extent of harmful algal blooms in Lake Erie - like the one that left my hometown of Toledo without drinking water in 2014

I have written a short statement responding to mass firings today of #NOAA / National Weather Service (#NWS) staff (which were concentrated among recent hires as well as highly experienced staff who had recently been promoted). Please see below screenshot & below for full text.
Statement begins: The mass firing of both new hires and recently promoted senior staff within NOAA, including mission-critical and life-saving roles at the National Weather Service (NWS), is profoundly alarming. It appears that NOAA staff fired today include meteorologists, data and computer scientists responsible for maintaining and upgrading weather predictive models, and technicians responsible for maintaining the nation’s weather instrumentation network (among many others). Housed within NOAA, the U.S. NWS is a truly world-class meteorological predictive service, perhaps singularly so. Its cost of operation is only ~$3-4/yr per taxpayer—equivalent to a single cup of coffee—and yields a truly remarkable return on investment (at least 10 to 1, and perhaps 100 to 1, depending on methods of estimation). NOAA and the NWS collectively offer tens to hundreds of billions of dollars each year in net economic benefit through a combination of averted losses and efficiencies gained....
