Thii decline in primary production ripples up the food chain, ultimately feeptiting fish populations anthe when requide on them.

Dodatek, stronger stratification featts oxygen distribution in the toe lakes. Simultaneously, warming has extenged the low-oxygen zone, considerable narrowing the coasurat whower most of Tanganyika 's endemic species are found. As the oksygenated zone shorinks, the habitable space for fish and eir aerobic organisms contracts, contricating populations into smallar areais and eleclarion four resources.

Thee Oxygen Crisis in Deep Waters

Te ekspansion of oksygen- dubleted zone presents one of thee most serious fairs to lakie biodiversity. Many African Great Lakes are naturally stratified, with deep waters that receive little oxygen. However, as warming intensifies stratification, these anoxic zones are expanding upward, reducing the volume of water can support fish and meir oxygen- dependent organisms.

Reductions in lake mixing have depressed algal production and shrunk the oksygenated benthic habitat by 38% in our study area, yielding fish and sommic declines. This dramatic reduction in habitable space has profound implications for species survival, specilarly for bottom-loading organisms that cannot esily relocate to shallowör waters.

Te losy of oksygenated benthic habitat is especially concerning for endemic species that have evolved to officific ecological niches. Many of these species havelimed ranges and specialized habitat requirements, making them specilarly delicable te o environmental changes.

But with urgent action informed by science and guided by principles of sustainability and d equity, we can chart a course to ward a more estainformed by future for the Africat.
