During our investigations of freshwater sites along the Atlantic Coastal Plain of North America we had the opportunity to critically study five interesting diatoms with light (LM) and scanning electron microscopy (SEM), each of which is described here as a new species. Two of the organisms are in the genus ...

Berry crops in the southwestern Yukon were quantified from 1997 to 2008 at 10 locations along 210 km of the Alaska and Haines highways. We tested the hypothesis that the size of berry crops could be predicted from spring and summer temperature and rainfall of years t, t-1 (1 year ...

The size of acorns produced by several species of eastern North American oaks decreases with latitude. We investigated three hypotheses for this pattern in the bur oak (Quercus macrocarpa Michx.) using samples collected over 2 years throughout the species' range. We found strong support for the hypothesis that abiotic factors, ...

To better understand the relationship between productivity and species richness after disturbance in the Neotropics, I tested two hypotheses using tree stem data collected in permanent plots set up after abandonment from agriculture. I found that (i) species richness had a significant positive relationship with productivity, where the slopes of ...
