#deadwood — Public Fediverse posts

A young tree seedling grows from the moss-covered trunk of a fallen oak. The decaying wood provides a growing surface for new plant life — a small example of natural forest succession, where dead trees continue to support the ecosystem long after they fall.

“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…"

The #rosechafer #Cetonia #aurata (#Scarabaeidae) is distributed from Europe to Asia. The #saprophagous #larvae develop over about two years in Central Europe in #soil substrates often under #deadwood. According to R. Beaven et al. (2025), #rectalcomplexes as in C. autata (larvae only) are recycling systems of the #gutcontents and #evolved #independently within Scarabaeideae.

I don't know why, but when I think of the best #film #villain or bad guy, #AlSwearengen from #Deadwood always comes to mind first. Absolutely fantastically developed and portrayed. #LoPan is also a blast, even if it's not as multi-layered. #filmsky #tvsky #hbo

What’s the best episode of #television you’ve ever watched? Recently: #ThePenguin #S01E04 #Deadwood: In the show, the circumstances of Smith's demise were changed to a gradual decay due to a brain tumor, though he was mercy-killed by #AlSwearengen (Ian McShane) before dying from the cancer. #WTF

Can someone help a #boomer out? My oldest is trying to explain the term based to me and having trouble getting it, BTW, not necessarily the radical right version of the term as #BannonTwoShirts uses it. Would you say that #AlSwearengen from #Deadwood is #Based?
