▪ Abstract In this review, we discuss the ecological and evolutionary consequences of plant-herbivore interactions in tropical forests. We note first that herbivory rates are higher forests than temperate ones that, contrast to leaves forests, most damage occurs when they young expanding. Leaves dry also suffer wet is greater understory canopy. Insect herbivores, which typically have a narrow host range tropics, cause selected for wide variety chemical, developmental, phenological defenses...
Explaining the mechanisms that produce enormous diversity within and between tropical tree communities is a pressing challenge for plant community ecologists. Mechanistic hypotheses range from niche-based deterministic to dispersal-based stochastic models. Strong tests of these require detailed information regarding functional strategies species. A few studies date have examined trait dispersion individual forest plots using species means in order ask whether coexisting tend be more or less...
1. To assess the degree of herbivore host‐specificity in moist tropical forest on Barro Colourado Island, Panama, I conducted an extensive series feeding trials common insect herbivores from 10 tree species. 2. The were offered leaves both congeneric and confamilial plant species to their known host species, as well most abundant forest. 3. amount damage caused by these young, expanding was also measured nine 4. Of 46 (seven Coleoptera, one Orthoptera, 38 Lepidoptera), 26% specialized a...
The Janzen–Connell model of tropical forest tree diversity predicts that seedlings and young trees growing close to conspecific adults should experience higher levels damage mortality from herbivorous insects, with the adult acting as either an attractant or source herbivores. Previous research in a seasonal showed this pattern distance-dependent herbivory occurred early wet season during peak new leaf production. I hypothesized may occur at time because foliage canopy attracts high numbers...
Abstract: The development of metacommunity theory, which suggests that the diversity and composition communities is influenced by interactions with other communities, has produced new tools for evaluating patterns community change along environmental gradients. These techniques were used to examine how plant changed elevation gradients in montane tropical forests. Two transects 0.1-ha vegetation plots established every 50 m mountains eastern Puerto Rico. ranged from 300 1000 asl 400 900 m....

The Black Belt region of Mississippi and Alabama has long been reported to contain prairies. To assess the extent distribution these prairies, this study examined historical accounts prairie in region, compiled a map based on surveyors' plat maps from 1830s compared flora existing fragments with other open ecosystems Southeast using data literature. Numerous attest presence prairies varying sizes, discretely bounded by forest. Surveys show that approximately 144,000 hectares were present...
Highlighting patterns of distribution and assembly plants involves the use community phylogenetic analyses complementary traditional taxonomic metrics. However, these are often unknown or in dispute, particularly along elevational gradients, with studies finding different based on elevation. We investigated how tree diversity structure change an elevation gradient using sampled 595 individuals (36 families; 53 genera; 88 species) across 15 plots (2440-3330 m) Ecuador. Seventy species were...
New leaf production in seasonal tropical forests may result from changes water or light availability. In this study, the relationship between flushing, photosynthetically active radiation (PAR) and rainfall was examined for understorey saplings a moist forest over one year. During wet season, weeks with greater PAR were correlated proportion of flushing new leaves during subsequent nine out ten species. Rainfall negatively leafing season six However, dry positively following species, but...
Blackland prairies are found in two regions of Mississippi and Alabama, the Black Belt Jackson Prairie Belt. As vegetation remnant these belts has received limited attention, we collected identified grasses forbs from 19 sites western Alabama over a year. A total 196 species were collected, including 168 native species. When compared with prairie lists for early 20th century, our results suggest that 18 present then may now be rare or absent. Habitat data indicate most favor more mesic...
Woody plant composition, trees per ha, and basal area, are provided for both units of the W.L. Giles Bur Oak Preserve, in Black Belt Prairie region Oktibbeha County, Mississippi. A total 1,273 individual were marked, measured, identified between two preserve. The southern unit contained 1,115 from 31 species was dominated numerically area by sugarberry (Celtis laevigata) green ash (Fraxinus pennsylvanica). northern 158 18 sugarberry, eastern redcedar (Juniperus virginiana), bur oak (Quercus...
