Contribution of predation to the biological control of a key herbivorous pest in citrus agroecosystems
(Wiley, 2019-03-21)
Biological control has traditionally simplified the view of trophic relationships between herbivorous pests and their natural enemies in agriculture. The success or failure of this pest management strategy is still mainly ...
Predation of Soil-Nesting Centris muralis (Insecta: Apidae) by Armadillos (Zaedyus pichiy) (Mammalia: Cingulata) in La Rioja Province, Northwestern Argentina
(Kansas Entomological Society, 2011-07)
This paper documents the predation of Centris muralis by Zaedyus pichiy. It presents the first detailed observations of the predation of solitary bee nests by a mammal in soils and reports the alternative use of soil mounds ...
Nest predation by arboreal snakes on cavity nesting-birds in dry chaco woodlandsDepredación por serpientes arborícolas en aves nidificantes de cavidades en los bosques del Chaco Seco.
(Neotropical Ornithological Society, 2011-09)
Ornithologists have extensively studied nest predation because predators are responsible for most nest failures (Ricklefs 1969, Martin 1995, Newton 1998). Factors correlated with variation in the occurrence of predation ...
Toxicity of the fungicide trifloxystrobin on tadpoles and its effect on fish-tadpole interaction
(Pergamon-Elsevier Science Ltd, 2012-02)
Contamination of aquatic systems is a major environmental stress that can interfere with predator-prey interactions, altering prey or predator behavior differentially. We determined toxicity parameters of the fungicide ...
Rhinella fernandezae (garden toad): eggs and embryos predation by leeches
(Society for the Study of Amphibians and Reptiles, 2018-07)
Predation of eggs and embryos is one reason for early mortality in anurans, and it is known that embryos of several amphibian species can accelerate their hatching as a mechanism to reduce predation risk (Warkentin 2000. ...
Variation in parental care in the spectacled tyrant Hymenops perspicillatus is associated with increased nest predation in grassland fragmentsUnterschiede in der Brutpflege beim Brillentyrann steht in Verbindung mit einer erhöhten Nest-Prädationsrate in fragmentiertem Grasland
(Wiley Blackwell Publishing, Inc, 2016-04)
Predation risk on birds is often an important source of natural selection that shapes parental care and may promote behavioral changes. Parents can often estimate certain risks and adjust their behavior to reduce the ...
Trophic ontogenetic shifts of the dragonfly Rhionaeschna variegata: the role of larvae as predators and prey in Andean wetland communities
(Edp Sciences, 2014-03)
Body size strongly influences the type and strength of species interactions. Animals with complex life cycles, such as dragonflies, usually go through different stages that include a variation in body size and may involve ...
Edge effect on bird nest predation in the fragmented caldén (Prosopis caldenia) forest of central Argentina: an experimental analysis
(Springer Tokyo, 2017-03)
Clearing of caldén (Prosopis caldenia) forests for agriculture and cattle raising in east-central La Pampa Province, central Argentina, has created a highly fragmented landscape, a condition that has resulted in adverse ...
Chemical defense in harvestmen (Arachnida, Opiliones): Do benzoquinone secretions deter invertebrate and vertebrate predators?
(Springer, 2005-11)
Two alkylated 1,4-benzoquinones were identified from the defensive secretion produced by the neotropical harvestman Goniosoma longipes (Gonyleptidae). They were characterized as 2,3-dimethyl-1,4-benzoquinone and ...
Medium-sized exotic prey create novel food webs: The case of predators and scavengers consuming lagomorphs
(PeerJ Inc., 2016-07)
Food web interactions are key to community structure. The introduction of species can be seen as an uncontrolled experiment of the addition of species. Introduced species lead to multiple changes, frequently threatening ...
