“In [this] article, [the author] explore[s]:
🌿 How beaver-created wetlands support biodiversity
🦟 Their potential influence on mosquitoes and other insect pests
🕷️ The indirect role they may play in tick ecology
🦇 How dragonflies, bats, birds, amphibians and beneficial insects contribute to natural pest regulation
🚜 What this could mean for sustainable agriculture and agroforestry
🌍 Why this matters for biodiversity, farming, and human and animal health in a changing climate…
The beaver isn’t simply creating wetlands. It may be rebuilding the ecological balance that our landscapes have gradually lost….”

[not my usual fare to post, but fascinating…]
“#Bigcats have a big impact. A long-term study showed that when mountain lions began regular visits to a small suburban preserve about 45 miles (72 kilometers) south of San Francisco, they changed the behavior of many other animals.
Mountain lions (Puma concolor) started appearing with increasing frequency on trail cameras at Stanford's Jasper Ridge Biological Preserve ('Ootchamin 'Ooyakma) from 2015 to 2020. Researchers documented a corresponding drop in deer activity compared with the prior years of lower or absent puma activity. Vegetation surveys also showed that many woody plants deer like to eat or tend to trample, including young oak trees, began to thrive.
These types of multilevel effects, called trophic cascades, have been studied primarily in large wilderness areas, particularly cascades caused by #apexpredators such as #wolves reintroduced into Yellowstone National Park...”

Wildlife monitoring in a 4.9 km^2 suburban preserve from 1972 to 2021 recorded almost no mountain lions until 2009, and after 2012 they were observed increasingly frequently. There were corresponding changes in deer, deer forage, and mesopredators (bobcat, coyote, and fox).

Note: no controls. The summary's reference to trophic cascade in Yellowstone has been called into question.

This is both amazing and beautiful: "A trophic cascade is an ecological process that starts at the top of the food chain and tumbles all the way down. A classic examples is when wolves were reintroduced to Yellowstone National Park..."

One of the classics of NZ ecological science is this Auckland study by Sandra Anderson and colleagues. They showed, in extraordinary detail, how the loss of two endemic flower-pollinating birds from mainland Auckland (korimako and hihi), and the relative rarity of another (tūī), have caused the population to falter of the endemic bird-pollinated plant taurepo, Rhabdothamnus solandri.
Plus, Australian silvereyes, now widespread in NZ, were nectar robbers and damaged a lot of the flowers.
Everything is connected, and the effects of species declines can be unexpected and initially easy to overlook.
"Nectar robbing by silvereyes, revealed by slit corolla tubes, was always rare on islands (means 3.2% of flowers near Whangarei and 4.3% near Auckland) compared with the mainland (14.1 and 79.2% in Whangarei and Auckland regions... These data reinforce the conclusion that a shortage of visits by endemic bird pollinators on the mainland is the cause of the failure of seed production and that recently self-introduced silvereyes are not effective substitute pollinators."

[not my usual fare (word play very much intended), but a fascinating and data-driven study; the study is not definitive, of course, but it adds to the scientific knowledge base, including with the socio-economic considerations…]
