MSN: Ice cores suggest dust, not CO2, once drove major climate shifts
Population Statistics & Trends Fawn to doe ratios and yearling buck percentages are used to help estimate the deer herd size annually and is the starting point for setting antlerless harvest quotas.
Harvest trends are provided and summarized by Deer Management Unit (DMU). Harvest within each DMU is tracked by the type of harvest (antlered vs antlerless), land type (public vs private), and by weapon type.
The primary objective of Long Term Trend (LTT) Lakes monitoring is to document long-term trends in lake water chemistry. This data set also provides context for water chemistry in other lakes in terms of intra and inter-annual variability.
Investigate trends in groundwater levels. Seepage lakes have no surface inlets or outlets, so lake levels are determined by precipitation, evaporation, and groundwater levels. Investigate relationships between lake level and other variables, such as water clarity, water quality, aquatic plants, and fish.
Eurasian watermilfoil: long-term trends in unmanaged populations The Wisconsin Department of Natural Resources conducts and supports a variety of projects that improve our understanding of aquatic invasive species (AIS) and the ways we manage them.

Ice core records stretching back hundreds of thousands of years show that airborne mineral dust, not carbon dioxide alone, played a leading role in driving some of the most dramatic climate shifts in ...
