#invertebrates — Public Fediverse posts

Amazing these otherworldly creatures inhabit the little ol' English coast. Unlike other #Devon #ctenophores we saw the Northern Comb Jelly (Beroe cucumis) lacks tentacles, instead engulfing other ctenophores with huge mouth. These ancient marine #invertebrates are largest animals to swim with cilia.

#Honeybees and #shrimp are now getting vaccinated
#Vaccines that target #invertebrates’ innate #immunesystems could be a major boon for agriculture
It has become increasingly clear that #innateimmunesystem has own way of creating immune memory. Scientists think this memory is achieved through #epigenetic changes, modifications to #DNA that don’t alter genetic sequence, and that these epigenetic changes can be passed from one generation to the next.

Busy Beavers - The Turbidity Signature Of Ecosystem Engineers At Work

“Beavers are the quintessential ecosystem engineers. In slow-flowing streams, they create complex wetlands with ponds by building dams and canals that can positively impact biodiversity, hydrology and water quality. These activities can interchangeably capture or release sediment along the watercourse. To date this has not been quantified at the resolution of rainfall events or beaver activity. This study used 15-min frequency, sustained monitoring upstream and downstream of a newly establishing beaver wetland to measure episodic changes in water turbidity at an event resolution. Monitoring showed no significant differences between upstream and downstream turbidity over 160 days when the first pair of beavers, known not to be building dams or canals, were resident. Shortly after introduction of another beaver pair, however, dam building, burrows and canal excavations were quickly observed, resulting in the creation of a complex beaver wetland between 2021 and 2024. Monitoring over 375 days during this period showed significant differences. Downstream turbidity was significantly higher overall than upstream: 13.1 Nephelometric Turbidity Units (NTU) compared to 4.2 NTU. Stochastic spikes in downstream turbidity during the study period not recorded upstream were associated with dam building and burrowing. Overall, there was no significant difference in turbidity loads, which was at least partially explained by a reduction in discharge downstream, particularly in higher flows, during the dam building period. This demonstrates a complex system with the trapping of influent sediment, the storing of water and the periodic release of beaver wetland sediment leading to net balance in loads. These results help provide context for other studies which have used temporally discrete sampling campaigns rather than continuous high-frequency monitoring. They provide a unique insight into the downstream impacts of a rapidly developing beaver wetland over its first three and a half years in a landscape that hasn't had beavers for over 400 years…"

“For seven years, planners struggled to complete a $1.2 million wetland restoration project in the Brdy region of the Czech Republic. The goal was to build a dam that would improve water management and bring back valuable wetland habitat, but the project remained trapped in a maze of permits and approvals.
Then a family of eight Eurasian beavers did what engineers had planned… without permits, machinery, or a budget.
The beavers built a network of dams in almost the exact area chosen for the proposed project, naturally restoring the wetland system officials had spent years trying to create. After seeing the results, authorities decided there was little point continuing with the original human-built dam.
Although some reports suggested the beavers completed the work overnight, experts say their construction likely took several weeks. The reason it seemed sudden is that the animals quietly worked away until their finished dams became impossible to miss.
Beavers are known as “ecosystem engineers” because their behaviour can reshape entire environments. By cutting trees and blocking streams, they create ponds and wetlands that support countless species, including fish, amphibians, insects, birds, and mammals.
Their wetlands also act as natural water reservoirs, helping during droughts, reducing flood risks, filtering water, storing carbon, and keeping landscapes wetter during wildfires…
Once heavily hunted across Europe, beaver populations have been recovering thanks to conservation efforts, proving that sometimes nature can solve problems humans spend years trying to fix…"

💁🏻‍♀️ ICYMI: 🐦🌀 If you've ever spotted a shorebird spinning in circles on the water, you might have wondered if it was okay.

Wilson's #phalaropes actually spin to create a small vortex that sucks #invertebrates up to the surface. It's a clever way to forage for food that some say makes them look like "demented wind-up toys."

At 09:09 this morning I decided it was a good time to take advantage of what the #wind had done overnight. A lot of #duckweed had accumulated in one of the bays in the #lake
visible from out lounge window.

With the aid of a angler's net attached to a long pole and a rake I managed to make a good stab of removing the weed along with some sludge and twigs found on the bed of the lake. It's now in a number of piles on the bank. I'll give it a day or two to allow #invertebrates to crawl back into the water and then move the piles to the #compost bins.
