The vascular flora of Chiapas, Mexico, has been the subject of a long term study by Dennis Breedlove of the California Academy of Sciences. This has stimulated a related project dealing with the bryophyte flora of the region. A collecting expedition in 1988 generated 1420 collections of bryophytes. Specialists from 13 institutions assisted with identifications. Approximately 70% of the collections have been determined. Checklists of species of bryophytes of Chiapas are presented. These lists are based on collections at CAS and literature citations. A total of 364 species of mosses and 310 species of hepatics and hornworts are reported from Chiapas.

At the end of the year 2012, Food and Chemical Toxicology published a long-term study by Seralini et al., describing the safety evaluation of genetically modified NK603 maize and Roundup herbicide. Contrary to previous, short-term studies, this experiment revealed some negative effects of these substances on the health of experimental animals. GM feeds and Roundup generate revenue worth millions of dollars. This may be the reason why Seralini’s paper has became the subject of much heated criticism, mainly from parties linked to business and agro-biotechnology. After one year of debate, the editors of Food Chem Toxicol. decided to retract the paper, an unprecedented event given that the published article was peer-reviewed and there was no evidence of plagiarism or fraud. Here, we stress the results of Seralini’s study, discuss the methodological hints of that work and cite the commentaries on the whole situation.

The Subject

In the late 1940's significant increases in the population of the spruce budworm, worm, Choristoneura fumiferana (Clem.), occurred in northern New Brunswick and culminated in a severe outbreak of this major forest pest. The outbreak has been the subject of intensive investigations dealing with emergency chemical control operations (Webb, 1956) and with a long-term study of the population dynamics of the budworm. The latter program, called the Green River Project, is located on the Green River Watershed in northwestern New Brunswick. Its objectives, the co-operating agencies involved, the mortality factors being studied, and methodology have been discussed elsewhere by Morris et al. (1956), Morris (1951), Morris and Miller (1954), and Morris (1955).

As part of the long-term study of the prehistoric archaeology of the Caddo peoples in Northeast Texas, we are currently focusing our investigations on the Little Cypress Creek valley in Upshur County. Although poorly known archaeologically, background research conducted to date, discussions with landowners, and selected survey-limited testing efforts over the last few years indicates that there are extensive Archaic and Caddoan archaeological remains preserved in the Little Cypress Creek valley. Caddoan period archaeologi cal sites (ca. A.O. 800-1600) are particularly common. The investigations of one of the more significant Caddoan sites found to date in the valley, the Griffin Mound site (41UR142), is the subject of this paper.
