Lacking catalase, a protistan parasite draws on its photosynthetic ancestry to complete an antioxidant repertoire with ascorbate peroxidase
(BioMed Central, 2019-06)
Background: Antioxidative enzymes contribute to a parasite's ability to counteract the host's intracellular killing mechanisms. The facultative intracellular oyster parasite, Perkinsus marinus, a sister taxon to dinoflagellates ...
Influence of the site of oviposition on the level of egg parasitism in the corn leafhopper, dalbulus maidis (Hemiptera: Cicadellidae)
(Academia Brasileira de Ciencias, 2021-03)
The corn leafhopper Dalbulus maidis (DeLong) (Hemiptera: Cicadellidae), transmits three important plant pathogens that adversely affect corn crop and ranges from the USA to Argentina. The vector has a rich natural enemy ...
Habitat fragmentation effects on trophic processes of insect-plant food webs
(Wiley Blackwell Publishing, Inc, 2006-02)
Habitat fragmentation is the transformation of once-extensive landscapes into smaller, isolated remnants surrounded by new types of habitat. There is ample evidence of impoverished biodiversity as a consequence of habitat ...
The first plastid genome of the Holoparasitic Genus Prosopanche (Hydnoraceae)
(MPDI, 2020-03)
Plastomes of parasitic and mycoheterotrophic plants show different degrees of reduction depending on the plants' level of heterotrophy and host dependence in comparison to photoautotrophic sister species, and the amount ...
Evolutionary History of the South American Mistletoe Tripodanthus (Loranthaceae) using Nuclear and Plastid Markers
(American Society of Plant Taxonomists, 2012-01-01)
Tripodanthus consists of three species that are endemic to South America. While T. acutifolius and T. flagellaris have East-West distributions in tropical and subtropical South America, T. belmirensis is restricted to its ...

Testing non-additive effects of nectar-robbing ants and hummingbird pollination on the reproductive success of a parasitic plant
(Springer, 2013)
Nectar robbing may have an indirect negative effect on plant reproduction by discouraging legitimate pollinator species from visiting robbed flowers. In this study, we set up a 2 × 2 factorial design with nectar-robbing ...
