This is due to photosynthesis rates in the leaves of rainforest species falling at higher temperatures and the trees&#8217; natural cooling systems failing during droughts. Increased heat threatens especially the species that store the most carbon. This has been shown in a new thesis from the University of Gothenburg.<\/p>\n<section class=\"article-banner first-banner ads-336x280\">\n         <!-- \/4988204\/Phys_Story_InText_Box --><\/p>\n<\/section>\n<p>Some species of trees are able to handle rising heat in the tropics by sucking up large quantities of water to their leaves and transpiring through wide-opened pores in their leaves. These are mainly fast-growing trees that establish themselves early as a rainforest grows up. The same cannot be said for the trees that make up the canopy of rainforests in old growth forests. They grow slower, but get bigger and taller, and their leaves do not have the same ability to cool themselves via transpiration.<\/p>\n<p><b>Water powers the &#8216;air conditioning&#8217; of the leaves<\/b><\/p>\n<p>&#8220;The tropics have not experienced Ice Ages and have thus had a relatively stable climate historically as well as seasonally. With climate change, it has started to get warmer and then we have seen that some species of trees are showing increased mortality rates, but we have not really known why before,&#8221; says Maria Wittemann, who wrote the thesis.<\/p>\n<p>She has studied several species of tree that can be roughly divided into early successional species, which establish themselves early in a new rainforest, and late successional species, which grow slower but grow considerably bigger, and are thus a larger carbon sink over the long term. A clear difference is how the trees in the two groups handle heat. The early successional species open the pores wider in their leaves, through which they transpire large amounts of water, thus keeping down the temperature in their leaves\u2014similar to an air conditioning system. The late successional species do not open their pores as much, and therefore it&#8217;s more difficult for them to stay cool.<\/p>\n<figure class=\"mb-4\" itemscope=\"\" itemtype=\"http:\/\/schema.org\/VideoObject\">\n    <meta itemprop=\"name\" content=\"Research shows that some trees become overheated in warmer rainforests\"\/><br \/>\n    <meta itemprop=\"url\" content=\"https:\/\/www.youtube.com\/watch\/?v=EkDvbwisqlQ\"\/><br \/>\n    <meta itemprop=\"description\" content=\"Credit: University of Gothenburg\"\/><br \/>\n    <meta itemprop=\"uploadDate\" content=\"2022-09-26T16:38:24-04:00\"\/><br \/>\n        <meta itemprop=\"embedUrl\" content=\"https:\/\/www.youtube.com\/embed\/EkDvbwisqlQ\"\/><br \/>\n    <meta itemprop=\"thumbnailUrl\" content=\"https:\/\/img.youtube.com\/vi\/EkDvbwisqlQ\/maxresdefault.jpg\"\/><\/p>\n<p>             <iframe loading=\"lazy\" title=\"Tropical montane forests in a warming world\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/EkDvbwisqlQ?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><figcaption class=\"text-darken text-low-up mt-4\" itemprop=\"caption\">Credit: University of Gothenburg<\/figcaption><\/figure>\n<p><b>More sensitive to drought<\/b><\/p>\n<p>&#8220;We found large temperature differences in the leaves in our measurements. There could be a difference of 10 degrees Celsius between late successional species and early successional species growing in the same location. The late successional species had more difficulty coping with abnormally high temperatures. These trees had a higher mortality rate,&#8221; says Maria Wittemann.<\/p>\n<p>However, the early successional species&#8217; profuse transpiration through their leaves also requires a lot of water. During a period of drought, the researchers noted that early successional species became more vulnerable to the heat and dropped their leaves. Their reduced consumption of water meant that late successional species were more resistant to drought.<\/p>\n<p>&#8220;Our results show that photosynthesis rates in rainforest trees falls when the temperature rises in their leaves, which occurs mainly in late successional species. The proteins and membranes in their leaves, that are essential for photosynthesis, fail, and eventually the trees die due to carbon starvation because they cannot convert enough carbon dioxide from the air. This affects the entire ecosystem. We know, for example, that some animals eat the fruits of the late successional species,&#8221; says Maria Wittemann.<\/p>\n<div class=\"article-gallery lightGallery\">\n<div data-thumb=\"https:\/\/scx1.b-cdn.net\/csz\/news\/tmb\/2022\/trees-get-overheated-i-1.jpg\" data-src=\"https:\/\/scx2.b-cdn.net\/gfx\/news\/hires\/2022\/trees-get-overheated-i-1.jpg\" data-sub-html=\"How rainforest trees tolerate higher temperatures is being studied in climate chambers at the University of Gothenburg.
