A multi-stressor scenario for the ocean and waterway ecosystems:

* The ocean is 'cooked' by the combustion of fossil fuels.
* Add a generous heap of 'nutrient-rich' floodwaters (runoff) from farms and suburbia.
* Get a harmful algal bloom (HAB) disaster, killing bio-diverse marine life and threatening the hip pocket nerve of coastal dwellers.

"A survey found that Australians remained far more concerned about disasters such as bushfires and flooding than they did HABs, despite 22 million people living with seven kilometres of the coastline and climate change modelling predicting more frequent and severe blooms."

"The study also found Australians had a "relatively low prioritisation of disasters — and HABs in particular — when compared with everyday socio-economic concerns"...Cost of living and healthcare dominated respondents' concerns in Australia, while environmental and climate change-related risks were perceived as less pressing.' >>

Most of my Himalayan Bird Count birding was in a Cold Temperate Forest with Oaks, Horse Chestnut, Indian Laurel, Rhododendrons, .

The central focus was around Mesar Kund , a forest pond.

The correct local name is Mesar Kund, long story about the that I will share soon. But this name is being changed to suit dominant cultural trends.

Brewing oceans, brewing storms, making a blooming disaster

"Over the past year, Australia’s oceans have been hotter than ever before...The continued burning of fossil fuels has caused our atmosphere to warm by approximately 1.2 degrees C since the pre-industrial era....If you change what happens in the oceans, you start to change the whole system...The problem with climate change is we’re hitting that system incredibly hard with extra energy and we’re putting a lot of pressure on the oceans."

We have known about the relationship between #nutrient_runoff, #eutrophication and #algaebloom of all types since at least 1970 (well, at least those of of us who were old enough to follow the news, and actually paid attention to the environmental news.) Why hasn't there been more action to correct these problems?

Lifeless rock pools at Sawtell

After cyclone Alfred whipped up a 'bacteria smoothy' along Australia's east coast the sea foam then merged with a 'flush' from the suburbs. Dislodged smelly sponges at Sawtell beach made breathing and contact impossible. Even without fossil fueled disasters the intertidal zone at the north end of the beach is barren. The rock pools and crevices no longer house sea anemones, crabs, black nerites, limpets, sea stars, mulberry oyster borers, algae, sea anemones, sponges, tube worms, sea stars, oysters, and fish.

Still good enough for hosting 'sports' and advertising events amplified by megaphone so they can be heard at Lord Howe Island too.

Early 2024, my 2nd PhD Chapter was published about the key roles of species body sizes and trophic positions in determining the outcomes of #invasivespecies in communities subject to gradients of #temperature and nutrients levels. A pretty cool study with N. Pichon, A. Sentis and D. Boukal.

Our results also demonstrate how anthropogenic disturbances (e.g. habitat #eutrophication) can have profound effects on freshwater communities, including sudden population collapses and cascading extinctions.

A look back at my 1st paper in 2021, when my 1st PhD chapter was out, on the role of body size and mesohabitats productivities in the linkage of #pelagic & #benthic systems, with David Boukal.

We show that
> 1) temperature-dependent vital rates, especially growth, are more important than temperature-driven changes in body size for community responses to #warming and #eutrophication
> 2) thermal niche mismatches between prey and predator have different effects on community transitions.
