Jesse Jackson, whose impassioned oratory and vision of a “rainbow coalition” of the poor and forgotten made him the nation's most influential Black figure in the years between the civil rights crusades of Martin Luther King Jr. and the election of Barack Obama, died on Tuesday at 84. Follow live.

4/4 Further, field replicates, when used as a proxy for the frequency of observation of a species through the seasons, yielded comparable temporal patterns to the ones extracted from the Global Biodiversity Information Facility (GBIF) for about 35% of investigated species.
@eawag.bsky.social #UZH
3/4 We assessed if #eDNA can capture the temporal changes of #Ephemeroptera, #Plecoptera, #Trichoptera, and #Diptera.
We found pronounced, cyclic phenological trends in most groups: the communities diverged from spring to summer and then in fall gradually returned closer to the spring state.
2/4 ➡️ #Aquatic #insects are ecologically highly relevant in riverine systems & used in monitoring programs 📈 to assess ecological states.
➡️ Commonly, monitoring is conducted at 1–2 timepoints/y, despite known phenology of aquatic insect strongly affecting species presence/detection across seasons.

Shifting leaf fall duration and order of arrival thus has the potential to impact carbon cycling, even when the combined resource quantity remains constant.
by #LukeIreland @tiannapeller.bsky.social & myself #UZH @eawag.bsky.social
➡️ Exposure duration and arrival order of leaf species strongly influenced combined leaf litter consumption. Earlier arrival of high-quality leaves enhanced feeding on low-quality leaves.
↔️ These subsidies are highly seasonally structured, yet their phenologies ⏰ are shifting with climate change 📈 .
We experimentally demonstrated how order of arrival and exposition duration of different leaf species 🍂 🍃 affect decomposition by amphipods 🦐 as a key aquatic ecosystem function.
Shifting leaf fall #phenology disrupts #ecosystem #function.

➡️ Leaf litter fall 🍂 and processing in temperate streams is one of the most pervasive resource subsidies and ecosystem functions globally 🌍 .

New paper in Oikos! 🎉
Ecosystems are connected by resource flows, and ecosystem size can mediate their effects. But how does size mediate the effects of resource flows between autotrophic and heterotrophic ecosystems—one of nature's most ubiquitous linkages?
A quiet start to the Holidays🎄: a bit of #birding with my son around Lake Pfäffikon. Kingfisher, kestrel, merganser 🐦⬛🦉🦆🦅🪶. No particular spectacular observation, yet wonderful foggy scenery. Spending time in nature nearby is among the best things one can do—pure happiness and relaxation.
indeed magic! its one of these enigmatic ecosystems/species that you here in lectures & books, would feel exactly the same!
