As the effects of climate change are starting to unearth themselves, the impacts can be observed by tracking the patterns of cyclical natural phenomena also known as phenology, and monitoring how they have changed over time. These cycles are at the crux of making ecosystems viable for their local biodiversity, and understanding the ongoing change allows for further understanding of the ecosystem’s change over time. In this study, we look at the ordinal flowering dates of the Achillea millefolium, Aquilegia coerulea, and Penstemon cyanocaulis over the past century. Our data give insight into how warmer temperatures occurring earlier in …


Wood-Inhabiting Fungi Of The Eastern Ecuadorian Cloud Forest: Fungal Diversity Comparison Along An Altitudinal Gradient In The Rio Zuñac Reserve, Thane Gehring, Rosa Batalles Apr 2020

Wood-Inhabiting Fungi Of The Eastern Ecuadorian Cloud Forest: Fungal Diversity Comparison Along An Altitudinal Gradient In The Rio Zuñac Reserve, Thane Gehring, Rosa Batalles

Wood-inhabiting fungi are responsible for the degradation of dead wood, playing a role in nutrient cycling and nutrient transport making them indispensable to their ecosystem’s health. Fungi are generally understudied, specifically in the tropics despite its proven hotspot in diversity and the importance of conservation. Wood-inhabiting fungi were investigated in the eastern Andean montane cloud forest of Ecuador to determine the biodiversity, distribution, and relation to an altitudinal gradient. Along multiple ridges of EcoMinga’s Rio Zuñac reserve, 13 20x20 meter (0.1-hectare) quadrants between the altitudes of 1300 to 2000 meters were sampled for wood-inhabiting fungi. A total of 175 samples …
