Ecology of fungi and their roles in decomposing refractory organic matters in lakes and ponds

我们研究了湖泊真菌的生态学及其在有机物分解中的作用。因巴湖真菌种类丰富，腐养壶菌占主导地位。腐养型壶菌可以消耗花粉等难降解有机物。分解花粉的壶菌是浮游动物的重要食物。数学模型表明，壶菌影响元素循环和营养转移效率。

We investigated the ecology of fungi in lakes and their roles in decomposing organic matters. In Lake Inba, we found diverse fungi, among which saprotrophic chytrids were dominant. Saprotrophic chytrids could consume refractory organic matters such as pollen. Chytrids decomposing pollen are found to be important foods for zooplankton. Mathematical models revealed that chytrids affected elemental cycling and trophic transfer efficiency.
