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. By using feld observations, laboratory experiments and spectrophoto...

This work discusses the criteria proposed to consider wild bees as bioindicators, and specifically applied to orchid bees in neotropical forests. Some of the issues are: 1) the deficiencies of the sampling methods, which makes it difficult to accurately assess species inventories. 2) missing knowledge about the biology of many species. 3) spatial o...

Introduction: Ephuta Say is a widespread New World genus of mutillid wasp whose ecology is poorly understood. Objective: The objective of this study was to determine how Ephuta species abundance varies annually and seasonally driven by weather conditions and hosts. Methods: Ephuta specimens, located in the “old forest” at Barro Colorado Island, w...

A taxonomic revision of the genus Scolia Fabricius, 1775 (Hymenoptera: Scoliidae) from Central America is presented. Two species of Scolia are present in Central America: S. (Discolia) guttata Burmeister, 1853 and S. (Hesperoscolia) rufiventris Fabricius, 1804, the latter representing the first record for Costa Rica, Panama and Colombia. The male o...

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 meta-analysis to evaluate trends in abundance and diversity of euglossine bees across strata. We found no evidence of stratification in terms of d...

Aim The study of the theory of island biogeographic (TIB) has focused mainly on plants and vertebrates, with support for the predictions that species richness decreases with distance from the mainland and increases with island size. However, less work has been done on invertebrates. Similarly, the study of the island rule has been studied mainly in...

Introducción: Carollia se caracteriza por la dificultad de identificar a los individuos de las diferentes especies. En Panamá no se ha realizado un estudio sobre la clasificación y la identificación correctas de las mismas; sin embargo, en otras regiones de América se han realizado estudios moleculares y filogenéticos que evidencian la dificultad d...

Guarumo leaves (Cecropia sp.) have been traditionally used in Latin America to manage diabetes mellitus.

Euglossini, or orchid bees, are Neotropical bees known for their fragrance harvesting behavior. This review, done by experts and conducted under Preferred Reporting Items for Systematic Reviews and Meta Analyses guidelines, summarizes four decades (1966-2022) of literature on their biology in Panama, including taxonomy, ecology, behavior, and conse...

A list of Scoliidae species recorded in Panama is presented. Considering the recent taxonomic updates made on this tribe of wasps, as well as the lack of a formal study on its geographical distribution, richness, and species diversity in Panama, this study aimed to document the existing species in the country. Based on literature records and an exa...

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 re...

Coloration anomalies are widespread across the animal kingdom; however, they pass underreported for some taxa or are extremely rare, like in the case of mammals. Three of those anomalies are albinism, leucism, and erythrism, each of which generates atypical colorations in white with white spots and reddish-brown, respectively. Here, we report five...

The reproduction of Neotropical snakes, such as those of the genus Leptodeira, varies widely influenced by climatic factors, with species ranging from strictly seasonal to continuous reproductive patterns. Recent research reveals significant variability in reproductive cycles, determined by local environmental conditions such as temperature and pre...

Vertical stratification in orchid bees is a small field, particularly suitable for an in-depth bibliometric analysis. We examined 13 publications to test the hypothesis that inclusion in databases is more important than language in the visibility and impact of publications about orchid bee stratification. Our findings matched the hypotheses: databa...

Body mass is an important morphological trait, which is associated with the physiology and ecology of insects. In the past, estimates of body mass were often based on general mathematical equations in which body mass was related to linear measurements of anatomical structures. For example, in female bees, estimates of dry body mass are expected to...

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...
