Snow: More Than Just the Backdrop for your Favorite Winter Olympic Sport

Even if you don’t live anywhere near mountains, it is very possible that the water that comes out of your tap originated as snow in the mountains. Many places rely on melting snow from the mountains to supply water downstream for cities, agriculture, and ecosystems. However, melting is not the only thing that can happen to mountain snowpack and scientists are trying to figure out where else it goes and how that could change in the future.

Connecting to nature and understanding ecosystem services: the urban perspective

Food and water – two resources vital for life on Earth. These are two prime examples of the products that arise from ecosystem services. There are four broad categories of ecosystem services: provisioning regulating, supporting, and cultural. Food and water are a form of ecosystem service provisioning – these are the products that directly benefit humans. Globalization and climate change are increasingly threatening food and water security, and other vital ecosystem services throughout the world.

Predicting nature’s trends: What is behind leaf turnover in temperate deciduous forests?

Finally, after five gruesome months spent doing field work in the Louisiana swamps sweating and inhaling mosquitos, I can sense the coming of fall. My coworker from Minnesota is not convinced however with temperatures still reaching above 90°F during the middle of the day. I try to explain that unlike further north where the changing of seasons is marked by an obvious change in temperature and vibrant alteration in the color of the landscape, seasonal change in the south takes a well trained eye to observe. The changes are a bit more obscure: A slight browning of the green swamp canopy, fewer bugs, and a small breeze. How do the trees decide the time is now to start the process of dropping all their precious foliage and why are there differences in preferred timing between various individuals living within the same area. More importantly, why do you care?

Of feces and fertilizer: residential sources of urban water pollutants

Excess nutrients from pet waste and lawn fertilizer contribute to degraded water quality in cities. Due to the widely dispersed nature of these pollutants in residential areas, decisions made at the household level can go a long way towards solving—or exacerbating—water quality problems.
