<i>Cyclosa</i> Menge, 1866 (Araneidae) Orb-Weavers Build Stabilimenta That Resemble Larger Spiders. [PDF]

Ecol Evol
The orb‐weaving spider Cyclosa longicauda from Peru constructs unique stabilimenta from detritus and silk that visually resemble a larger spider. This previously undescribed behavior likely functions as a sophisticated anti‐predator strategy, with the structure serving as a decoy to misdirect or repel attacks.

Lack of response of an open-habitat ungulate to the presence of predator urine La falta de la respuesta de un ungulado de habitat abierto a la presencia de orina de depredadores

Revista Chilena de Historia Natural, 2008
The behavioral response of ungulates to the presence of odors associated with dangerous predators has received some attention, yet little is known about how predominantly open-habitat ungulates react to the presence of predator scents.

Coexisting with large carnivores based on the Volterra principle. [PDF]

Conserv Biol
Abstract Coexistence with large carnivores represents one of the world's highest profile conservation challenges. Ecologists have identified ecological benefits derived from large carnivores (and large herbivores), yet livestock depredation, perceived competition for shared game, risks to pets and humans, and social conflicts often lead to demands for ...

Urban developmental environments alter tadpole phenotypes depending on origin. [PDF]

J Anim Ecol
Urbanisation has rapidly altered the ecological and evolutionary contexts for many species. Using a reciprocal transplant experiment with frog larvae, we find that urban environments can alter morphological, developmental and behavioural traits at both ecological and evolutionary scales.

Effects of protection on large-bodied reef fishes in the western Indian Ocean. [PDF]

Conserv Biol
Abstract Predatory and large‐bodied coral reef fishes have fundamental roles in the functioning and biodiversity of coral reef ecosystems, but their populations are declining, largely due to overexploitation in fisheries. These fishes include sharks, groupers, Humphead wrasse (Cheilinus undulatus), and Green Humphead parrotfish (Bolbometopon muricatum).

Shearing Tooth Morphology May Allow Sharks to Access Higher Trophic Levels at Smaller Sizes. [PDF]

Ecol Evol
Predator morphology imposes limitations on prey selection due to biomechanical constraints, making some prey functionally inaccessible and thereby constraining predator trophic niches. We assessed how two key components of trophic morphology—tooth shape and body size—affect prey selectivity and trophic niche in two sympatric sharks with contrasting ...
