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.
A 27-year study of the largest colony of Magellanic penguins in the world, published in 2014, found that extreme weather caused by climate change kills 7% of penguin chicks in an average year, accounting for up to 50% of all chick deaths in some years. [76] [77] Since 1987, the number of breeding pairs in the colony has reduced by 24%. [77]
Survival of Parelaphostrongylus tenuis, a brain worm of white-tailed deer that affects moose, could be increased due to the higher temperatures and milder winters that are caused by climate change. In moose, this brain causes neurological disease and eventually ends up being fatal. Moose are already facing heat stress due to climate change, and ...
Bacterial diseases are a leading cause of death and a future without effective antibiotics would fundamentally change the way modern human as well as veterinary medicine is practised. [ 196 ] [ 197 ] [ 198 ] However, legislation and other curbs on antibiotic use in farm animals are now being introduced across the globe.
In biology, overabundant species refers to an excessive number of individuals [1] and occurs when the normal population density has been exceeded. Increase in animal populations is influenced by a variety of factors, some of which include habitat destruction or augmentation by human activity, the introduction of invasive species and the reintroduction of threatened species to protected reserves.
See more on climate change: A University of New Hampshire researcher says the horses, originally approximately the size of a dog, "may have gone down to the size of a cat." That's not the only bad ...
A new study ranked the top 10 most dangerous states for habitability in the U.S., including factors like climate and air quality. Other factors included natural hazards and accidents, non-violent ...
Human-caused climate change and the rise in invasive species are directly linked to changing of ecosystems. [6] [7] The destabilization of climate factors in these ecosystems can lead to the creation of a more hospitable habitat for invasive species, thus allowing them to spread beyond their original geographic boundaries.
