ABSTRACTA striking feature of most scorpion species is fluorescence under ultraviolet light, but fewstudies have investigated the adaptive benefit of this trait. A hypothesis is that fluorescencemay lure prey towards the scorpion improving foraging success. In this study, we investigatedwhether the fluorescence of the scorpion Centruroides granosus Thorell, 1876 lures the housecricket Acheta domesticus Linnaeus, […]

AbstractAnts are an abundant and diverse group with worldwide distribution. Given their omnipresence, ecosystem services,and potential applications, ants may be excellent models for multiple lines of research such as physiology. However, thefocus and worldwide distribution of ant physiology research are unknown. Given the evidence of scientific colonialism inmultiple scientific areas – where credit and reward

Predators exert negative effects on prey, besides the act of killing, generating behavioral and physiological costs, a concept known as the ecology of fear. Studies in scatter-hoarding rodents in temperate zones suggests that prey use habitat structure to perceive predation risk. Less is known about how tropical forest rodents perceive predation risk. Here, we investigated

Abstract – We measured abundance, diversity, and richness of Euglossa bees (Euglossini, Apidae) in lowlandsemi-deciduous forest in Darién National Park, Panamá, during the wet and dry seasons in the canopy andunderstory for five consecutive years (2013 to 2017) using McPhail traps baited with eucalyptus oil. We found aprecipitous decline in abundance and richness throughout the

ABSTRACTEmpirical evidence of immune priming in arthropods keeps growing, both at thewithin- and trans-generational level. The evidence comes mostly from work on insectsand it remains unclear for some other arthropods whether exposure to a non-lethaldose of a pathogen provides protection during a second exposure with a lethal dose.A poorly investigated group are arachnids, with regard

AbstractRoadkill monitoring can provide important information about spatial and temporaltrends on roadkill events. These studies are important for conservation, but thereare few examples from Central America. Here, I identified in a road near a nationalpark in Panama that monthly vertebrate roadkill events decreased with increases intemperature and precipitation.

Abstract – We report the occurrence of Brachyplatys subaeneus (Westwood, 1837) on a new hostplant species: the leguminose Macroptilium longepedunculatum. We discovered thebugs in the mouth of the river San Juan in Coiba National Park in Panama. Wepresent the morphological and barcode species level identification. This insect pestnormally attacks plants of economic importance within cultivated

Abstract – Vertical stratification of animal assemblages has been observed in several arthropod taxa. However,for some groups there is conflicting evidence, such as for the neotropical orchid bees. Here, we used a metaanalysisto evaluate trends in abundance and diversity of euglossine bees across strata. We found no evidence ofstratification in terms of diversity, but abundance

The omnipresence of pathogens makes them a strong selective pressure for most organisms, generating a variety of defensive responses to fight them. One mechanism by which organisms can release this pressure is avoidance of the pathogens in a spatial or temporal context. To date, only a few biological systems provide evidence that habitat selection can
