Descriptions of two new species of nun birds from Panama

Two new species of Monasa are among the interesting birds collected by E. A. Goldman while working on the Smithsonian Biological Survey of Panama during the winter of 1911. They were collected at the same locality on the base of Cerro Azul, northwest from Chepo, and only a single specimen of each was obtained. No others were seen during the entire season in the Canal Zone and adjacent territory...(Document contains 4 pages)

Two new subspecies of birds from Panama

While working on the Smithsonian Biological Survey of the Canal Zone, Mr. E. A. Goldman of the Biological Survey, United States Department of Agriculture, collected specimens of two undescribed subspecies of birds which are characterized below. (Document contains 3 pages)

A Remarkable new fern from Panama

Toward the last of February, 1911, in the course of fieldwork connected with the Smithsonian Biological Survey of the Panama Canal Zone, I accompanied Mr. Henry Pittier from the Canal Zone, where our work had been carried on up to that time, to Chiriqui, the westernmost province of Panama, and spent nearly all of March in collecting plants--mainly ferns and lower cryptogams--in the mountains north of David, the principal city of the province...(Document contains 10 pages)

Descriptions of new genera, species and subspecies of birds from Panama, Colombia, and Ecuador

The first of January, 1912, E. A. Goldman, of the Biological Survey, Department of Agriculture, was again detailed on the Smithsonian Biological Survey of the Canal Zone. He returned to Panama in January and remained there until the last of June passing most of this period in collecting birds and mammals on the slopes of Mount Pirri on the Pacific side of eastern Panama, near the Colombian border...(Document contains 27 pages)

New mammals from eastern Panama

During the early part of the present year I was again detailed from the Biological Survey, U. S. Department of Agriculture to field work in connection with the Smithsonian Biological Survey of the Panama Canal Zone. Additional collections of mammals and birds were made in January and February in the Canal Zone. From the latter part of February to near the end of June work was carried on in eastern Panama to determine the faunal relation of the region to the Canal Zone and the better known areas to the westward and northward. The work was centered in the Pirri range of mountains which rises to a height of over 5,000 feet near the Colombian boundary southeast of San Miguel Bay...(Document contains 20 pages)

Descriptions of new mammals from Panama and Mexico

Further study of the collection of mammals taken by the writer while detailed from the Biological Survey, U.S. Department of Agriculture, to the Smithsonian Biological Survey of the Panama Canal Zone has resulted in the discovery of eleven new species and subspecies in addition to those already published...(Document contains 22 pages.)

Descriptions of twelve new species and subspecies of mammals from Panama

In the early part of 1911 a collection of 368 mammals was made by me while engaged in the biological survey of the Canal Zone, and adjacent parts of Panama, undertaken by the Smithsonian Institution in cooperation with several government departments, including the War Department and Department of Agriculture. This collection, representing between 40 and 50 genera, includes 12 new species and subspecies which are here published in advance of a general report on the mammals of the region...(Document contains 13 pages)

Two new subspecies of birds from the slopes of Mount Pirri, eastern Panama

The two subspecies described below were part of the rich collection made by E. A. Goldman in Eastern Panama, during the season of 1912, while engaged in the Smithsonian Biological Survey of Panama. Other new birds from this collection were described in a recent paper...(Document contains 4 pages)

New species of fishes from Panama

The fishes described in the following pages were collected by the authors in the fresh waters of Panama, while engaged in field work on the Biological Survey of the Canal Zone; the ichthyological work of which is being conducted cooperatively by the Smithsonian Institution, the Field Museum of Natural History and the Bureau of Fisheries. A complete account of all the fishes collected during the past two years on this survey is in the course of preparation. (Document contains 16 pages)

Descriptions of new genera and species of microlepidoptera from Panama (with one plate)

The following decriptions [sic] of new forms of Microlepidoptera are published in advance of proposed papers, dealing with the lepidopterous fauna of Panama as a whole, based on material collected by the writer as a member of the Smithsonian Biological Survey of the Panama Canal Zone during the first half of the year 1911. ...

Temporary ponds in the UK; a critical biodiversity resource for freshwater plants and animals

The importance of ponds for biodiversity in Britain has been demonstrated by a number of studies. However, most of the research and interest has been directed at permanent waterbodies, and temporary ponds have been largely neglected. In this article the author present some preliminary findings from a project which aims to fill some of the many gaps in our knowledge of temporary ponds in Britain. The project, which runs for three years until the end of 2001, aims specifically to investigate the ecology of temporary ponds in England and Wales by describing (i) their wetland plant and macroinvertebrate communities, (ii) their physico-chemical characteristics, and (iii) their value as a biodiversity resource. The article focuses on the assessment of temporary ponds as a biodiversity resource and briefly considers aspects of species richness, rarity and distinctiveness. Where possible, temporary ponds are compared with other waterbody types, mainly permanent ponds from the National Pond Survey (NPS), to give the results a broader context.

Distribution of ommastrephid paralarvae in the eastern tropical Pacific

Jumbo squid (Dosidicus gigas) and purpleback squid (Sthenoteuthis oualaniensis) (Teuthida: Ommastrephidae) are thought to spawn in the eastern tropical Pacific. We used 10 years of plankton tow and oceanographic data collected in this region to examine the reproductive habits of these 2 ecologically important squid. Paralarvae of jumbo squid and purpleback squid were found in 781 of 1438 plankton samples from surface and oblique tows conducted by the Southwest Fisheries Science Center (NOAA) in the eastern tropical Pacific over the 8-year period of 1998–2006. Paralarvae were far more abundant in surface tows (maximum: 1588 individuals) than in oblique tows (maximum: 64 individuals). A generalized linear model analysis revealed sea-surface temperature as the strongest environmental predictor of paralarval presence in both surface and oblique tows; the likelihood of paralarval presence increases with increasing temperature. We used molecular techniques to identify paralarvae from 37 oblique tows to species level and found that the purpleback squid was more abundant than the jumbo squid (81 versus 16 individuals).
