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 ...
Artificial light at night as a driver of urban colonization by an avian predator
(Springer, 2021-01)
Context: Urbanization and artificial light at night (ALAN) are major drivers of local biodiversity losses causing community alterations, disruption of predator-prey interactions, and ultimately, promotion of cascading ...
Quantifying predation on galaxiids and other native organisms by introduced rainbow trout in an ultraoligotrophic lake in northern Patagonia, Argentina: A bioenergetics modeling approach
(American Fisheries Society, 2009-05)
Exotic rainbow trout Oncorhynchus mykiss support an economically valuable recreational fishery in Patagonia but also create concern for impacts on native organisms. These concerns are intensified by the possibility of ...
Trophic ecology of a top predator colonizing the southern extreme of South America: Feeding habits of invasive American mink (Neovison vison) in Tierra del Fuego
(Elsevier Gmbh, 2013-02)
The American mink (Neovison vison) is a semi-aquatic, generalist carnivore released onto Tierra del Fuego (TDF) Island in the 1940s, subsequently spreading to adjacent islands in the archipelago with potential effects on ...
Weak trophic links between a crab-spider and the effective pollinators of a rewardless orchid
(2015-01)
Sit and wait predators hunting on flowers are considered to be exploiters of plant–pollinator mutualisms. Several studies have shown that plant–pollinator interactions can be highly susceptible to the impact of a third ...

Trophic interactions and metal transfer in marine ecosystems driven by the Peruvian scallop Argopecten purpuratus aquaculture
(Wiley, 2022)
This study investigates the trophic interactions and As and Cd transfer along seven marine ecosystems in Peru. Five of these ecosystems are driven by aquaculture of the Peruvian scallop Argopecten purpuratus. A southward ...
Sympatric otariids increase trophic segregation in response to warming ocean conditions in Peruvian Humboldt Current System
(Public Library of Science, 2022)
Determining trophic habits of predator communities is essential to measure interspecific interactions and response to environmental fluctuations. South American fur seals, Arctocephalus australis (SAFS) and sea lions Otaria ...
Topological properties of polar food webs
(Inter-Research, 2013-01)
Mean annual temperatures of the Arctic Ocean and Antarctic Peninsula are warming much faster than global mean warming rates, which will likely result in significant biological impacts. Whereas most assessments have been ...
