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

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

Effect of uneven tolerance to human disturbance on dominance interactions of top predators. [PDF]
Abstract Anthropogenic activities may alter felid assemblage structure, facilitating the persistence of tolerant species (commonly mesopredators), excluding ecologically demanding ones (top predators) and, consequently, changing coexistence rules. We aimed to determine how human activities influence intraguild relationships among top predators and ...

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

La decision de Fernando VII en 1814 de separar radicalmente los asuntos y gobierno de su Real Casa y Patrimonio de los mas generales de la Hacienda y del Estado ha sido interpretada a menudo como una manifestacion de racionalidad administrativa. Lejos de eso, en este trabajo demostramos como este acto fue el inicio de una deriva patrimonializadora, de ...
