Cyanobacteria (blue-green algae) bloom on Lake Erie (United States) in 2009. These kinds of algae can cause harmful algal bloom. A harmful algal bloom (HAB), or excessive algae growth, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to other organisms, or by other means.
Microcystins cannot be broken down by standard proteases like pepsin, trypsin, collagenase, and chymotrypsin due to their cyclic chemical nature. [30] They are hepatotoxic , i.e., able to cause serious damage to the liver .
Many cases of anatoxin-a related animal deaths have occurred due to ingestion of detached benthic cyanobacterial mats that have washed ashore. [7] Anatoxin-a producing cyanobacteria have also been found in soils and aquatic plants. Anatoxin-a sorbs well to negatively charged sites in clay-like, organic-rich soils and weakly to sandy soils.
Global warming may not just melt the polar icecaps and create a snowpocalypse previously only seen in 'The Day After Tomorrow.'
I knew that bloat was extremely dangerous, but I had not seen a demonstration like this one from Garret before that explains it in such an easy-to-understand way. Commenters were also appreciative ...
Severe weather is one type of extreme weather, which includes unexpected, unusual, severe, or unseasonal weather and is by definition rare for that location or time of the year. [5] Due to the effects of climate change , the frequency and intensity of some of the extreme weather events are increasing, for example, heatwaves and droughts .
However, this unique phenomenon shows how birds, master migrators, can adapt to various weather conditions. The Sunshine State is home to some 1.3 million alligators, the most in the country.
Unlike those animals, which can generate their own heat internally (endothermic), insects must rely on external sources to provide their heat (ectothermic). Thus, insects persisting in winter weather must tolerate freezing or rely on other mechanisms to avoid freezing. Loss of enzymatic function and eventual freezing due to low temperatures ...
