The primary goal of this Web site is to enable users to identify crickets, katydids, and cicadas from America north of Mexico. The males of most species in these groups make loud, persistent calls that attract sexually ready, conspecific females. Because the songs are loud and species specific they are usually an easy means of identifying the caller. They also facilitate field and laboratory studies of many sorts. Secondary goals are to attract amateur and professional biologists to the study of ... [Information of the supplier]

Im Frühjahr 2005 startete das Tagfalter-Monitoring Deutschland. Jahr für Jahr erfassen Freiwillige bei wöchentlichen Begehungen entlang festgelegter Strecken (Transekte) alle tagaktiven Schmetterlinge. Die so entstehenden Bestandsdaten dokumentieren die Entwicklung der Falter auf lokaler, regionaler und nationaler Ebene und können verglichen werden mit denen aus anderen europäischen Ländern, in denen die Beobachtungen z. T. schon seit Jahrzehnten erfolgen. Das Projekt findet breite Unterstützung, ... [Information of the supplier]

The aim of this site is to help you to name daffodil cultivars. Churchyards, municipal plantings and parkland are the best places to search for daffodils, and the best time to look for them is between January and April. Most of the plants you find outside gardens will have been planted intentionally or will have grown from fly-tipped waste; few will have come from seed.
You need to understand from the outset that many of the plants you find cannot be named with certainty: most cultivars are just ... [Information of the supplier]

The Interactive Key to Malesian Seed Plants is an identification system for all native and naturalised (i.e. introduced species with self-maintaining 'wild' populations) families of the Flora Malesiana region (including Malaysia, Brunei, Singapore, Indonesia, Philippines, East Timor and Papua New Guinea). The key is based on a small set of features of the vegetative, floral and fruit morphology and ecology. These features were chosen because they are relatively easy to assess from any reasonably ...

Although these literature searches were originally conceived as providing working documents for our own researches, it soon became apparent that this comprehensive catalogue of literature and illustrations should be made generally available rapidly and freely as a working tool for all those interested in working on Trichoptera material from Africa, especially for colleagues in far-distant institutes and without access to large libraries. Each page will record the name of the species, its distribution, ... [Information of the supplier]
