Frogs of the Solomon Islands

This key is designed for live specimens of the 21 frog species from the political Solomon Islands (excludes Bougainville). It is mainly for use with adult specimens but may be used for juveniles if body size is not used. We have included photographs or line drawings of the natural variation in most of the characters to help the user. We have also included photographs of each species and tried to incorporate the natural variation in morphology, particularly skin colour and patterning where applicable.

Fruits of Brazilian Savanna Attractive to Wildlife (Frutos Atrativos do Cerrado)

The Cerrado biome is considered the richest savanna of the planet. It is the second biggest vegetation domain of Brazil, occupying 22% of its territory, and has about 12.000 species of vascular plants. From this, it is estimated about 4.000 species producing fruits attractive to wildlife, distributed in 300 genera. The correct identification of fruit species is important in studies of plant-animal interactions. The aim of this key is to represent the most common fruit species of all genera. This key is also a complement of the first volume of the book “Fruits and Seeds of Cerrado Attractive to Wildlife” (Frutos e Sementes do Cerrado Atrativos para Fauna) and, currently, has about one third of all genera of Cerrado fruits.

Key characters for identification process and each of the species are illustrated by photographs. For each species it is also presents a fact sheet with more information.

Human Impacts Pollen Collection

A Pollen Identification Key

While many pollen reference collections emphasize indigenous regional, often arboreal taxa, the Human Impacts Pollen Collection focuses on taxa relating to peoples’ impacts on the environment and landscape. These include cultivated and ornamental plants, but also ruderals, segetals, exotics, and invasives, which are often, although not exclusively, forbs, grasses, and shrubby taxa. This collection of pollen reference materials provides a tool for helping to identify the pollen from these types of plants and reconstruct changing vegetation patterns. The collection contains plants relating to human activities in the Caribbean, Iceland, and elsewhere, but focuses primarily on the North American landscape within the last 500 years. However, some of these taxa were introduced from Eurasia, Africa, and Australia. As such, the development of a database of these materials provides information that complements regionally-based collections that are focused on indigenous vegetation. The key has several thousand images of pollen from about 800 specimens.
