Introduction Touching certain plants can be dangerous. Many plants are highly poisonous when ingested, this is common knowledge. It is remarkable, however, that simply touching certain plant species can also be a serious health hazard. The infamous Stinging Nettles are rather harmless in this respect, but there are much more dangerous contact-poisonous plants in many parts of the world, especially in the tropics. They can cause severe pain, rashes, blisters and leave scars. Some trees are reported to be so powerful that even raindrops falling from them can irritate the skin. This document wants to give a concise overview of all contact-poisonous plants that may be of interest for travellers. Information about this interesting subject is usually hard to find, as it is scattered across many different sources like scientific works about dermatology or botany, regional field guides, travel literature, and magazines.

Solvin Zankl Photography. Mushrooms of SW Ohio. Raccoon. The raccoon ( Though previously thought to be solitary, there is now evidence that raccoons engage in gender-specific social behavior. Related females often share a common area, while unrelated males live together in groups of up to four animals to maintain their positions against foreign males during the mating season, and other potential invaders. Home range sizes vary anywhere from 3 hectares (7 acres) for females in cities to 50 km2 (20 sq mi) for males in prairies. After a gestation period of about 65 days, two to five young, known as "kits", are born in spring. Etymology The mask of a raccoon is often interrupted by a brown-black streak that extends from forehead to nose.[8] The word "raccoon" was adopted into English from the native Powhatan term, as used in the Virginia Colony.

Taxonomy Track Evolution Subspecies Four subspecies of raccoon found only on small Central American and Caribbean islands were often regarded as distinct species after their discovery. Description Skeleton Senses. Butterfly. Butterfly flying around a flower Etymology The name is derived from Middle English buterflie, butturflye, boterflye, from Old English butorflēoge, buttorflēoge, buterflēoge, perhaps a compound of butor (beater), mutation of bēatan (to beat), and flēoge (fly).[2] Life cycle Mating Common Buckeye Butterflies The face of a Dryas iulia, more commonly known as a Julia butterfly.

Butterflies in their adult stage can live from a week to nearly a year depending on the species. Butterflies may have one or more broods per year. Eggs Butterfly eggs are protected by a hard-ridged outer layer of shell, called the chorion. Butterfly eggs are fixed to a leaf with a special glue which hardens rapidly. Eggs are almost invariably laid on plants. The egg stage lasts a few weeks in most butterflies but eggs laid close to winter, especially in temperate regions, go through a diapause (resting) stage, and the hatching may take place only in spring.
