The Paradox of Forest Fragmentation Genetics
TLDR
It is argued that population genetics theory may be misapplied in light of ecological realities that, when recognized, require scrutiny of underlying evolutionary assumptions.
Managing Species Diversity in Tallgrass Prairie: Assumptions and Implications
  • H. Howe
  • Environmental Science
  • 1 September 1994
Conservation and restoration ecology efforts may conserve or restore a particular image of a community, a variety of plausible images, or maximum biological diversity. The choice is a policy decision
Early Consequences of Seed Dispersal for a Neotropical Tree (Virola surinamensis)
TLDR
The results demonstrate clear advantages to local seed dispersal for a tree of the rainforest canopy and suggest that dispersal of seeds > 20 m by large birds, such as guans and toucans, is more favorable for seedling survival than that of the smaller trogons and motmots, which regurgitate seeds under or near the tree crown.
Response of Early‐ and Late‐Flowering Plants to Fire Season in Experimental Prairies
  • H. Howe
  • Environmental Science
  • 1 February 1994
TLDR
Replicated mid—July burns, simulating the peak of lightning—caused fire in natural grasslands, strongly influenced species composition and cover in experimental restorations in southern Wisconsin.
Characterization of highly variable (GA/CT)n microsatellites in the bur oak, Quercus macrocarpa
TLDR
The results, indicating that (GA/CT)n microsatellites are both abundant and highly polymorphic in the bur oak genome, suggest that such genetic markers have tremendous potential for applications for studies of parentage, pollination and dispersal in temperate trees.
Episodic death across species of desert shrubs.
Extreme events shape population and community trajectories. We report episodic mortality across common species of thousands of long-lived perennials individually tagged and monitored for 20 years in
When Seed Dispersal Matters
TLDR
The key issue is that variance in survival of plant life-history stages, and therefore the importance of dispersal, differs greatly among and within plant communities.
Low Recruitment of Trees Dispersed by Animals in African Forest Fragments
Abstract: We investigated the effects of forest fragmentation on the disappearance of fruit‐eating animals and the recruitment of animal‐, wind‐, and gravity‐dispersed trees in 80‐year‐old forest
EGG SIZE, HATCHING ASYNCHRONY, SEX, AND BROOD REDUCTION IN THE COMMON GRACKLE'
TLDR
The overall pattern of brood reduction in this species is interpreted as an evolved system by which a 9 parent reduces risks so as to maximize inclusive fitness.
Arrival and Survival in Tropical Treefall Gaps
TLDR
This work focuses on three issues that, for any species, define probable regeneration at a given site: (1) pattern of seed arrival in gaps and beneath the canopy, (2) proportion of forest area in gap vs. closed canopy, and (3) survival to reproductive maturity of seeds landing in gap and under the canopy.
