An Annotated Checklist of Invasive Species of the Phyla Arthropods and Chordates in Panama.

Invasive species are one of the five main causes of biodiversity loss, along with habitat destruction, overexploitation, pollution, and climate change. Numbers and species of invasive organisms represent one of the first barriers to overcome in ecological conservation programs since they are difficult to control and eradicate. Due to the lack of records of invasive exotic species in Panama, this study was necessary for identifying and registering the documented groups of invasive species of the Chordates and Arthropod groups in Panama.

Assessment of the Quality, Chemometric and Pollen Diversity of Honey from Different Seasonal Harvests.

The parameters for assessing the quality of honey produced by are standardized worldwide. The physicochemical properties of honey might vary extensively due to factors such as the geographical area where it was produced and the season in which it was harvested. Little information is available on variations in honey quality among different harvest periods in tropical areas, and particularly in neotropical dry forests.

Description of the male of Suárez, 1960 (Hymenoptera, Mutillidae), including new information on the biology of the genus.

The male of Suárez, 1960 is described and associated with the female based on couples reared from trap-nests occupied by Dreisbach, 1963 (Hymenoptera: Pompilidae). Information on the diapause of and Pseudomethoca nr. chontalensis (Cameron, 1895) (Hymenoptera: Mutillidae) is presented.

Immune priming against bacteria in spiders and scorpions?

Empirical evidence of immune priming in arthropods keeps growing, both at the within- and trans-generational level. The evidence comes mostly from work on insects and it remains unclear for some other arthropods whether exposure to a non-lethal dose of a pathogen provides protection during a second exposure with a lethal dose. A poorly investigated group are arachnids, with regard to the benefits of immune priming measured as improved survival.

Age variation in the body coloration of the orb-weaver spider Alpaida tuonabo and its implications on foraging.

Spiders show a repertoire of strategies to increase their foraging success. In particular, some orb-weaver spiders use attractive body colorations to lure prey. Interestingly, coloration varies with age in many species, which may result in ontogenetic variation of foraging success.

A new species of Banks, 1944 (Hymenoptera, Pompilidae, Pompilinae) from Panama.

Priochilus chrysopygus Wasbauer, Cambra & Añino sp. nov. based on both sexes is described and illustrated.
