Are there species smaller than 1 mm?
The rapid advance in genetic sequencing technologies has provided an unprecedented amount of data on the biodiversity of meiofauna. It was hoped that these data would allow the identification and counting of species, distinguished as tight clusters of similar genomes. Surprisingly, this appears not to be the case. Here, we begin a theoretical discussion of this phenomenon, drawing on an individ...

The claim is often made that functional programs are \more" expressive than their imperative counterparts. This paper examines this claim using a particular measure of (i) program length and (ii) programming language \level" (a measure of expressive power) both from the work of Halstead on software metrics. This paper was presented at the 1996 Glasgow Functional Programming Workshop, held in Ul...

متن کاملHow many species are there?
'How many species are there' is a question receiving more attention from biologists and reasons for this are suggested. Different methods of answering this question are examined and include: counting all species; extrapolations from known faunas and regions; extrapolations from samples; methods using ecological models; censusing taxonomists' views. Most of these methods indicate that global tot...
