Population-level compensation by an invasive thistle thwarts biological control from seed predators.
Pre-dispersal seed predators are often chosen as biocontrol agents because of their high impacts on plant fitness; however, they have a mixed record in realizing decreased plant population growth. Few studies have experimentally removed agents to explore their impact on weed population growth. Here, we used manipulative experiments with invasive yellow starthistle (YST), Centaurea solstitialis,...
متن کاملSeed dispersal by neotropical seed predators.
From a plant's perspective, the difference between a seed predator and a seed disperser should be straightforward: attract animals that will disperse seeds and defend seeds from potential predators. Unlike pulp-eating frugivores, seed predators regularly encounter diverse plant protective mechanisms. The purpose of this paper is to examine feeding constraints, morphological adaptations, and the...
متن کاملInteractions Between Pea Seed - borne
approved: Richard 0. Hampton Pea seed-borne mosaic potyvirus pathotype 1 (PSbMV-P1) has the ability to infect most genotypes of Pisum sativum. The exception are those genotypes that are homozygous recessive for the sbm-1 gene. The life cycle of PSbMV pathotype 4 (PSbMV-P4) is unaffected by the sbm-1/sbm-1 genotype. Infectious clones of Pl-P4 recombinants were used to define the genomic segment ...
متن کاملSynchrony between fruit maturation and effective dispersers' foraging activity increases seed protection against seed predators.
The evolution of pollination and seed dispersal mutualisms is conditioned by the spatial and temporal co-occurrence of animals and plants. In the present study we explore the timing of seed release of a myrmecochorous plant (Helleborus foetidus) and ant activity in two populations in southern Spain during 2 consecutive years. The results indicate that fruit dehiscence and seed shedding occur mo...
متن کاملUndercover predators: Vegetation mediates foraging, trophic cascades, and biological control by omnivorous weed seed predators
Blubaugh, Carmen K. Ph.D., Purdue University, May 2015. Undercover Predators: Vegetation Mediates Foraging, Trophic Cascades, and Biological Control by Omnivorous Weed Seed Predators. Major Professor: Ian Kaplan. Weed pressure is the most costly challenge that vegetable growers face, requiring more labor investment than other production inputs. Vertebrate and invertebrate seed predators destroy...
