Herbivore damage along a latitudinal gradient: Relative impacts of different feeding guilds

Article Abstract:

The first broad-scale test for a latitudinal gradient in herbivory made with consistent methods, in similar habitat type, over the entire lifespan of leaves (phyllodes) is presented. The degree of chewing, sap-sucking and mining herbivory on Acacia falcata along its entire coastal latitudinal range in Australia is assessed.

Competition coefficients in a marine epibenthic assemblage depend on spatial structure

Article Abstract:

The dynamics of multispecies assemblages depends on the topology of interaction networks and the nature and strength of interactions among each pair of species. The outcome of overgrowth rates and interactions of pairs of species is compared in contrived as well as unmanipulated assemblages.

Larval gregariousness and neonate establishment of the eucalypt-feeding beetle Chrysophtharta agricola (Coleoptera: Chrysomelidae: Paropsini)

Article Abstract:

Research indicates that initial group density, leaf margin damage and leaf age influence neonate larval survival in the beetle species Chrysophtharta agricola, which inhabits eucalyptus trees. Larval mortality was also found to be higher on older leaves.
