Social Recognition in the Arachnida
2015More than 99 % of arachnid species are solitary, aggressive and often cannibalistic predators. A few species are social and cooperative, but they do not reach the level of eusociality found in some insects. Kin recognition is suggested to be a key feature for the evolution of cooperation and sociality and thus found predominantly in those few species ...

Heymons (1901), the author of the term Chelicerata, united Merostomata (Eurypterids and Xiphosurans) with Arachnida in one monophyletic group. Dunlop and Selden (1997) restricted this term to Lemoneites, Xiphosura, Chasmataspida, Eurypterida, and Arachnida. There were many attempts to create a “natural” system of the monophyletic (Wheeler et al.

Concerning the fossil orders, Dunlop (1996a, b) presents a revised concept of the formerly accepted (Weygoldt and Paulus 1979; Shultz 1990) five fossil orders of Arachnida. The subclasses of Petrunkevitch (1949) have been rejected, Anthracomartida – synonymized with Trigonotarbida.

This chapter examines distinguishing characteristics of medically relevant ticks with a focus on those found in the United States of America and the disease states they cause in humans. Preventative techniques to minimize tick exposures will also be discussed.

Arachnida: Spiders and Scorpions
2020Though there are over 40,000 species of spiders and 2,000 species of scorpions worldwide, many spiders are incapable of biting humans and very few spiders and scorpions produce clinically significant bites or stings. Most spider bites and scorpion stings in humans cause minimal or no effects and rarely result in more than a local cutaneous reaction ...

There are several important related features of climate and topography which play a major role in the distributions of invertebrate populations in southern Africa. Southern Africa has one of the richest arachnid faunas in the world and this is probably due to the wide range of habitat types ranging from extreme desert to forest within a relatively ...
