The Mars Desert Research Station (MDRS) is a Mars-simulation campus set in a Martian planetary analogue in southern Utah. Despite a long history of astrobiology research, collections-based taxonomic inventories of the macro-level biodiversity around the station are relatively new. This study serves to add to the initial vascular plant list published for the station in 2016, where 39 species were recorded for MDRS. Here we report 40 new species, two new taxa recorded only to genus and two species re-identified from our 2016 fieldwork, bringing the total number of taxa in the "Martian" flora to 79 species and two taxa recorded to genus.

History Of

By August 2017 an estimated 13,047 species and subspecies of extant reptiles have been described by a total of 6,454 papers and books which are listed in a supplementary file. For 1,052 species a total of 2,452 subspecies (excluding nominate subspecies) had been described by 2017, down from 1,295 species and 4,411 subspecies in 2009, due to the elevation of many subspecies to species. Here we summarize the history of these taxon description beginning with Linnaeus in 1758. While it took 80 years to reach the first 1,000 species in 1838, new species and subspecies descriptions since then have been added at a roughly constant rate of 1000 new taxa every 12-17 years. The only exception were the decades during World Wars I and II and the beginning of this millennium when the rate of descriptions increased to now about 7 years for the last 1,000 taxa. The top 101 most productive herpetologists (in terms of “taxon output”) have described more than 8,000 species and subspecies, amounting to over 60% of all currently valid taxa. More than 90% of all species were described in either English (68.2%), German (12.7%) or French (9.3%).

Article 50

This paper clarifies the confusion relating to the publication of Carlos de la Torre & Paul Bartsch’s taxonomic study of theCuban Urocoptidae. This massive work, which described >500 new taxa, was completed in manuscript form in 1943, butwas not published during the authors’ lifetime. In 1972 Miguel Jaume and Alfredo de la Torre (a nephew of C. de la Torre)published a slightly modified version of a large portion of this manuscript in the Circulares del Museo y Biblioteca deZoología de la Habana, a mimeographed journal which is available for taxonomic purposes per ICZN Code Article 8. The420 new taxa introduced in this paper were made available under the ICZN Code (even though many were differentiatedonly in identification keys) and should be attributed to C. de la Torre & Bartsch because the descriptions were copied fromthe 1943 manuscript and Jaume & A. de la Torre explicitly credited this work to the former two authors (per Article 50 ofthe 1964 edition of the ICZN Code). The 1972 paper does not delineate type material for most of the new species-grouptaxa; however the detailed information provided in the 1943 manuscript constitutes valid evidence of the type series perICZN Code (1999) Article 72.2. The 1972 paper was republished by Jaume & A. de la Torre in 1976 in the Ciencias Bi-ológicas of the Universidad de la Habana. In 1980 Jaume & A. de la Torre prepared a typescript describing the remainingnew taxa from the 1943 manuscript, which was slated to be published in the Circulares; however we have not found anyevidence that it was distributed or otherwise made available in a manner satisfying the ICZN Code criteria for availability.In 2008 Carolina de la Torre, grand-niece of C. de la Torre, published the entire 1943 manuscript in a book of more than760 pages that was printed in Havana. The authorship of this book was credited to C. de la Torre & Bartsch. The bookdescribes as new the taxa already treated in the 1972 paper as well as 130 additional taxa, which also should be attributedto C. de la Torre & Bartsch. We briefly discuss the disposition of the Cuban urocoptid material studied by C. de la Torre & Bartsch and the subsequent citations to their taxonomic study of this fauna.

A new species of the genus Drosophila, Drosophila sagittifolii sp. nov. is described. Adult specimens of D. sagittifolii were aspirated from the inflorescences of Xanthosoma sagittifolium (L.) Schott (camacho), from which they also emerged, at the Río Guajalito Research Station, Santo Domingo de los Tsáchilas, Ecuador.

Review of specimens and names of Faramea Aubl. (Rubiaceae, Coussareeae) has required new nomenclatural combinations, clarified the identities of some previously described species, and discovered some new taxa. Here we transfer two Faramea names, F. suaveolens Duchass. and F. panurensis Müll. Arg., to Coussarea Aubl.; review the identities of F. cuencana Standl., F. multiflora A. Rich., F. oblongifolia Standl., F. parvibractea Steyerm., F. spathacea Müll. Arg. ex Standl., and F. suerrensis (Donn. Sm.) Donn.

In 1957 James R. Beer, Edwin F. Cook and Robert G. Schwab, of the University of Minnesota, conducted an investigation of mammals and their ectoparasites in the Chiricahua Mountains of southeastern Arizona. The area studied included varied habitats in the general vicinity of the Southwestern Research Station of the American Museum of Natural History at Portal. An account of this investigation has now been published (Beer et al., 1959).

SUMMARYRecords on 695 lambs were collected over a period of 5 years from 1961/62 to 1965/66, at Ras El-Hekma Desert Research Station, 230 km west of Alexandria. The characters studied were birth, weaning and yearling body weights, pre- and post-weaning daily gains and greasy fleece weight.Birth, 120-day and 365-day body weights were 3·4, 18·2 and 33·4 kg respectively. Greasy fleece weight at 16 months of age was 3·29 kg. Heritability estimates of birth, weaning, yearling weights, pre- and post-weaning daily gains and greasy fleece weight were 0·22, 0·45, 0·41,0·45 and 0·29 respectively. Genetic and phenotypic correlations between birth, weaning and yearling weights were all positive and significant. Genetic correlations between fleece weight and body characteristics were negative and low.

This paper contains a report on a collection of parasitic protozoa from the blood of some vertebrate animals of Uganda.Seven new species and a number of parasites recorded for new hosts are described. New observations on some known parasites are also recorded.An account is given of the life history of the crocodile haemogregarine. It is shown that the schizogony of Hepatozoon pettiti (nomen novum for Haemogregarina pettiti) occurs in the liver of the crocodile, while the sporogony takes place in Glossina palpalis, its intermediate host.A list of all the blood parasites found, together with their hosts, is given.
