1. The abundance, survival, and causes of mortality of Cameraria hamadryadella (Clemens) (Lepidoptera: Gracillariidae) were examined on four host plant species in Virginia, U.S.A. Quercus alba L. and Q.rubra L. are native within the geographic range of C. hamadryadella, and Q. robur L. and Q. benderi Baenitz are exotic. Q.robur is native to Europe, North Africa, and Asia and was probably introd...

We examined reassembly of winning and losing tree species, species traits including shade and fire tolerance, and associated disturbance filters and forest ecosystem types due to rapid forest change in the Great Lakes region since 1850. We identified winning and losing species by changes in composition, distribution, and site factors between historical and current surveys in Minnesota's mixed a...

Studies of the effects of logging on Lepidoptera rarely address landscape-level effects or effects on larval, leaf-feeding stages. We examined the impacts of uneven-aged and even-aged logging on the abundance, richness, and community structure of leaf-chewing insects of white (Quercus alba L.) and black (Q. velutina L.) oak trees remaining in unharvested areas by sampling 3 years before and 7 y...

(2) Our campus squirrel population provides ample opportunities to explore squirrel feeding preferences or scatterhoarding behaviors. Many of the findings summarized in a series of papers by Steele and Smallwood (e.g., “What are squirrels hiding? Natural History 10: 40-44. 1994. and other findings reported in their articles) offer challenging field experiment ideas. For example, given that spec...

We used LANDIS, a model of forest disturbance and succession, to simulate successional dynamics of forests in the southern Appalachian Mountains. The simulated environments are based on the Great Smoky Mountains landscapes studied by Whittaker. We focused on the consequences of two contrasting disturbance regimes—fire exclusion versus frequent burning—for the Yellow pine (Pinus L., subgenus Dip...

Oaks (Quercus) are economically important, and their seed (acorns) a valuable food for many animals. Thus, forest managers must consider potential tradeoffs between oak growth acorn production. I used 13 years of dbh 17 trapping data on 195 trees five common eastern species to compare stand-level production closed canopy mature (M) recent shelterwood with reserves regeneration harvests (SW) (BA...
