Over the 20th century, surface water temperatures have increased in many lake ecosystems around world, but long-term trends vertical thermal structure of lakes remain unclear, despite strong control that stratification exerts on biological response to climate change. Here we used both neo- and paleoecological approaches develop a fossil-based inference model for mixing depths thereby refine understanding We focused three common planktonic diatom taxa, distributions which previous research...
Course-based undergraduate research experiences (CUREs) for non-science majors (nonmajors) are potentially distinct from CUREs developing scientists in their goals, learning objectives, and assessment strategies. While national calls to improve science, technology, engineering, mathematics education have led an increase revealing the positive effects of science majors, less work has specifically examined whether nonmajors impacted same way. To address this gap our understanding, a working...
We compared phytoplankton diversity and productivity over various time scales in a set of lakes the central Rocky Mountains North America (fed by both glacial snowpack meltwaters [GSF] alone [SF]) to better understand influence nitrogen‐rich meltwater on structure function phytoplankton. Nitrate concentrations GSF were average 44 times higher than SF, even though only 0.01–0.59% catchment area was covered glaciers. In three each type, we determined vertical distribution algae, epilimnetic...
We investigated the response of lake algal communities to changes in glacial meltwater from Renland Ice Cap (Greenland) through Holocene assess whether influxes always elicit consistent responses or novel responses. measured sedimentary pigments two proximal lakes, snow-fed Raven and glacier- Bunny Lake, diatom community structure turnover Lake. Diatom data were not available also modeled lake-level change Lake identify how may have altered habitat availability time. Through a series glacier...
Abstract The alpine–subalpine Loch Vale watershed (LVW) of Colorado, USA, has relatively high natural lithogenic P 5+ fluxes to surface waters. For 1992–2018, the largest number stream samples with concentrations ([P ]) above detection limits occurred in 2008, corresponding highest frost-cracking intensity (FCI). Therefore, cold winters and warm summers a comparatively low mean annual temperature partly influence [P ]. Sediment cores were collected from Loch, an outlet lake LVW. Iron-, Al-,...
