Ambush predators depend on cryptic body colouration, stillness and a suitable hunting location to optimise the probability of prey capture. Detection of cryptic predators, such as crab spiders, by flower seeking wasps may also be hindered by wind induced movement of the flowers themselves. In a beach dune habitat, Microbembex nigrifrons wasps appro...

Predation is one of the main interactions between organisms and one of the primary selective agents for their survival. Both prey and predators have developed different strategies and characteristics that allow them to be conspicuous or go undetected. In sit and wait predators, their shape and appearance are important factors that allow them to rem...

Background and aims: Ant-plant associations are widely diverse and distributed throughout the world, leading to complex ecological networks. Regarding ant-plant mutualism, ant pollination is a very rare interaction and few studies have shown the role of ants as pollinators. Therefore, we aimed to evaluate the role of ants as effective pollinators...

Many animals use body coloration as a strategy to communicate with conspecifics, prey, and predators. Color is a trade-off for some species, since they should be visible to conspecifics but cryptic to predators and prey. Some flower-dwelling predators, such as crab spiders, are capable of choosing the color of flowers where they ambush flower visit...

Although there is a large diversity of plant species with extrafloral nectaries, histological detail of these glands is poorly documented in tropical rain forest species. We characterized extrafloral nectaries using digital photographs, scanning electron microscopy and histological methods for eight plant species belonging to the Costaceae, Euphorb...

All mutualistic plant–animal interactions are mediated by costs and benefits in relationships where resources (from plants) are exchanged by services (from animals). The most common trading coin that plants offer to pay for animal services is nectar; the main servers are hymenopterans. Extrafloral nectar (EFN) is produced in almost all aboveground...

We surveyed of 50 individuals of Heliconia uxpanapensis C. Gut. Báez, an understory herb common in the forest and trail sides of Los Tuxtlas Biological Station, a tropical rainforest. In these plants we found the presence of beetles of the genus Chelobasis in the Sierra de Los Tuxtlas, being the first record of the genus for Mexico. Los Tuxtlas is...

Qué son los humedales? Cuando se habla de humedales lo primero que viene a la mente son los manglares, sistemas naturales do-minados por agua con mangles que presentan raíces espectaculares que sobresalen de la superficie del agua, semejando grandes zancos. Existen diferentes tipos de humedales y, a pesar de la variedad de sus atributos en todo el...

We evaluate the behavior that arthropods (prey) present against their possible predators in different biological scenarios.
