In April 2009, Sir David Attenborough, the respected face and voice of British natural history programmes for more than fifty years, became the patron of a new charity, the Optimum Population Trust (OPT), an organisation campaigning to limit the world’s population. His reason for accepting the honour, he confessed to The Times, was that he was terribly worried about the dramatic increase of the...

A new record of the tarantula genus Phlogiellus Pocock, 1897 from Thailand is described. Distributional data, natural history, morphological characters, and illustrations of male and female are provided. The Thai specimens belong to a new species, Phlogiellus longipalpussp. n. The diagnosis of the new species and related species are discussed.

The species of the mostly Neotropical Region Apocephalus analis group are revised, and found to comprise 21 species, 19 of which are new to science: A. bilineatus, A. euryacanthus, A. holdenae, A. mexacanthus, A. paracanthus, and A. rectisetus in the newly recognized A. comatus series, and the following unclassified species: A. amacayacuensis, A. amati, A. amenti, A. amorimi, A. camarae, A. cri...

The study of the adaptive manipulation of animal behavior by parasites is entering very exciting times. Collectively the field has moved from its important and instructional natural history phase into proximate-level studies aiming to elucidate the mechanisms by which one organism controls another. Because many cases studies involve cross-kingdom control of behaviour, the findings are sure to b...

Natural selection generally produces specific and efficient enzymes. In contrast, directed evolution experiments usually produce enzyme variants with broadened substrate specificity or enhanced catalytic promiscuity. Some proteins may be more evolvable than others, but few workers consider this problem when choosing starting points for laboratory evolution. Here, we review the variables associa...

During their first visit to Brazil, in 2001, Michel Van Praet, Jean Davallon, and Daniel Jacobi - French researchers in the field of museology - discussed the complex nature of the museum experience. Professor Van Praet underscores the unique character of natural history museums and offers an evaluation of his work as head of the restoration project at Paris's Grande Gallery of Evolution, inaug...

Remote oceanic islands have long been recognized as natural models for the study of evolutionary processes involved in diversification. Their remoteness provides opportunities for isolation and divergence of populations, which make islands remarkable settings for the study of diversification. Groups of islands may share a relatively similar geological history and comparable climate, but their i...
