La región Centroamericana constituye un puente entre grandes faunas de Norteamérica y Suramérica. Este sitio persigue la incorporación de participantes que estén interesados en constituir un sitio que recoja información básica sobre la fauna de Arácnidos que habita esta región. Queremos llegar a ser una herramienta de consulta eficiente e interactiva para el uso diverso de la información, queremos actualizar las listas de faunas locales, paginas de especies, mapas de distribución y herramientas de clasificación e identificación para conocer mejor lo que tenemos que cuidar y heredar a nuestras futuras generaciones. Haste miembro y participa como colaborador!!
El uso de la información en este sitio está limitado a "uso justo, no comercial".

The Central American region is a biodiversity bridge between North and South American arachnid faunas. This site seeks the inclusion of participants who are interested in forming a cyber place that collects basic information about the arachnids that inhabits this region. We want to become a reference tool for efficient and interactive use of diverse information, we want to update the lists of local faunas, species pages, distribution maps, plus identification and classification tools to better understand what we have to care for and pass to our future generations. Please come and join us by becoming a collaborator.

Lichens - stable, mutualistic associations of fungi and algae - are well-represented in tropical areas. Bermuda is home to many Caribbean lichen species, and thus provides a useful gateway for lichenological exploration of the neighboring Greater and Lesser Antilles.
The primary objective of this site is to document and explore the diversity of Bermudian lichens, as well as the fungi which parasitize them (lichenicolous fungi). As our investigation of the Bermudian lichen flora continues, taxonomic and nomenclatural questions arise which affect a wider audience. This site provides a forum for discussion of these questions. You are invited to register and contribute to the taxonomy of Caribbean and neotropical lichens species. Discover the power of lichen cybertaxonomy!

Learn about freeloader flies, which dare share the dinner of spiders, mantids and other predatory insects much larger than themselves.
Read a short introduction about the family Milichiidae (Diptera, Schizophora) or visit the species pages with information about and photos of common, beautiful and/or important species.

Classification of animals observed or collected for biological inventories predominantly relies on visual attributes. However, many animals generate acoustic signals for communication and orientation, which are predestined for eavesdropping on their presence and behaviour. Acoustic signals can be registered over varying distances, allowing for unobtrusive detection and observation of their producers. Acoustic observations are well established for e.g. birds, insects, anurans, bats or whales. Depending on type of signals and taxonomic group, species identification, abundance estimation or behavioural assessment is possible. But physical properties of sound require certain precautions during recording, analysis as well as interpretation. We outline these prerequisites, describe types of bioacoustical signals for major taxonomic groups, and present a short review on state-of-the-art equipment and methods for bioacoustic recording and analyses. We sum up with a step-by-step key on how to proceed in bioacoustic inventories and research.
