A further investigation of leaf sesquiterpene variation in relation to herbivory in two Brazilian populations of Copaifera langsdorfii
TLDR
Higher yields and more variable concentrations of certain compounds may be important in restricting herbivores such as gelechiids and oecophorids on C.langsdorfii and may partially be a result of historically different intensities and types of herbivory.About:

Higher plant terpenoids:a phytocentric overview of their ecological roles
TL;DR: Characteristics of higher plant terpenoids that result in mediation of numerous kinds of ecological interactions are discussed as a framework for this Symposium on Chemical Ecology of Terpenoids, and the role of terpenoid mixtures is emphasized.

Chemistry of Cirsium and Carduus: a role in ecological risk assessment for biological control of weeds?
TL;DR: It is suggested that further research on thistle chemistry in insect feeding is warranted, since the exotic Canada thistle (Cirsium arvense) is an invasive thistle of current concern in North America and such research on mechanisms underlying host range expansion by exotic insects would be useful.

Elevational variation of quinolizidine alkaloid contents in a lupine (Lupinus argenteus) of the Rocky Mountains.
David B. Carey,Michael Wink +1 more
TL;DR: Alkaloid levels of leaves of seedlings were significantly higher in those seedlings derived from populations of low elevations than those of high elevations, indicating that the observed differences in the field are at least partly genetic and not environmental.

The Role of Mixtures and Variation in the Production of Terpenoids in Conifer-Insect-Pathogen Interactions
TL;DR: The regulation of natural populations was debated intensively during the 1950s and 1960s, and continues to be an important topic of investigation, and the field has advanced to investigations at the tritrophic level; and the linking thread among trtrophic interactions is to a large extent the natural products produced by plants.

Seasonal changes in oak leaf tannins and nutrients as a cause of spring feeding by winter moth caterpillars
Paul Feeny,Paul Feeny +1 more
TL;DR: The content of oak leaf tannins, which inhibit the growth of winter moth larvae, increases during the summer and may render leaves less suitable for insect growth by further reducing the availability of nitrogen and perhaps also by influencing leaf palatability.

Advances in legume systematics
TL;DR: An examination of the phylogenetic relationships of Papilionoideae and the relationships in Caesalpinioidae and Mimosoideae is examined.

Phytophagous Insects as Regulators of Forest Primary Production
TL;DR: Although outbreaks (either local or extensive) do reduce plant production temporarily, they commonly occur in individual plants or in whole forest systems that are not particularly productive-that is, those which are under stress resulting from inadequate or excessive moisture, nutrient deficiencies, or pollution, or are senescent, having already passed their peak efficiencies in biomass production.
Journal ArticleDOI
Differences in Insect Abundance and Diversity Between Wetter and Drier Sites During a Tropical Dry Season
TL;DR: When compared with temperate data on insect communities there are indications that the four tropical communities examined have a much greater number of species and possibly a greater internal uniqueness than similar temperature communities.
Journal ArticleDOI
Fluctuations in Abundance of Tropical Insects
TL;DR: The data suggest that physical stability and predictability of the environment are important for determining the AV of the insects and that the wet but seasonal tropics are physically no more stable than the wet temperate zone.
