Introduction
My interests lean on Cognition in invertebrates but also on Navigation, Sensory Ecology, and mimicry. Currently looking for a Postdoc position on these areas.

Article
Jumping spiders (Salticidae) use exceptional vision, largely mediated by their forward-facing anterior lateral (AL) and anterior medial (AM) eyes, to pounce on prey from a distance. We evaluated depth perception through the use of 'texture density' (depth estimation through surface texture comparisons, with greater distances having higher textural...
Article
Several non-mutually exclusive hypotheses have been proposed to explain the evolution of cognition in animals. Broadly, these hypotheses fall under two categories: those that pertain to the selective pressures exerted either by sociality or by the ecological niche in which animals live. We review these ideas and then discuss why the highly visual j...

The article Widespread army ant aversion among East African jumping spiders (Salticidae)
Article
Animals often rely on different sources of information when making decisions about the environment. Here, we assessed whether two jumping spiders (Salticidae), Trite planiceps and Portia fimbriata, take two different sources of information into account when jumping over water, to which they are averse. Specifically, we investigated whether salticid...

Jumping spiders (Salticidae) typically prey on a variety of arthropods of similar size to themselves, but rarely on ants. Using 28 salticid species from East Africa, we first investigated vision-based aversion to ants by recording latency to enter a transparent sealed chamber flanked by chambers containing living army ants (Dorylus sp.) or tsetse f...

To take an indirect route (detour) in order to reach a specific target requires complex cognitive processes. Yet more demanding, from the cognitive point of view, is when the goal is only visible at the beginning of the detour. In spiders from the family Salticidae, vision is a key sensory modality mediating navigation and prey search. Their acute...

Selection on individuals that incorporate risk to quickly and accurately make a priori navigational assessments may lead to increased spatial ability. Jumping spiders (Araneae: Salticidae) are characterized by their highly acute vision, which mediates many behaviors, including prey capture and navigation. When moving to a specific goal (prey, nest,...

Prey signalling to predators is an attempt to divert or nullify an attack even before it occurs. If these signals are backed up by a potent defence, then the likelihood of the predators learning to avoid them is high. In species that use deceptive signalling, predators could learn to overcome such a display and diminish the efficacy of the display....
Article
Full-text available
Interactions between prey and predators are often mediated by signals sent by the prey. Passive signals such as aposematic coloration and active signals such as pursuit deterrence signals are thought to prevent attack from predators. In true fruit flies (Diptera: Tephritidae), the defensive wing display is called supination, and studies have shown...
Article
Predators often adopt strategies to capture prey that reflect both the characteristics of the prey and their own hunger level. In generalist spiders of the family Salticidae, predatory behavior typically consists of four phases: orientation towards the prey, pursuit, crouching, and jumping to capture. In this study, we conducted laboratory experime...
Article
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...
Article

Fruit flies (Diptera: Tephritidae) are major pests worldwide. The sterile insect technique, where millions of flies are reared, sterilized by irradiation and then released, is one of the most successful and ecologically friendly methods of controlling populations of these pests. The mating behaviour of irradiated and non-irradiated flies has been c...
