The great abundance and good preservation of the remains of the American Mastodon have led to various restorations of the skeleton. The best known of these is that made by Prof. Richard Owen, in 1846, based upon a skeleton from Missouri, now in the British Museum. Another restoration was made a few years later by Dr. J. C. Warren, based mainly on a very perfect skeleton from Orange county, New York. This skeleton is now preserved in the Warren Museum in Boston. A third restoration was made by Prof. James Hall, from a skeleton found at Cohoes, New York, and now in the State Museum of Natural History, in Albany. These restorations are all of importance, and taken together have made clear to anatomists nearly all the essential features of the skeleton of this well-known species.

Tree Fruits

The thrips Frankliniella tritici (Fitch) occurred in great abundance early in May, 1954, in orchards of tree fruits in Essex County, Ontario.Observations during the first three weeks of May showed that this insect was abundant on the foliage and blossoms of apple, sweet and sour cherries, plum, and peach. Sweet cherry, European plum, and peach suffered the greatest attack. On sweet cherry and plum large numbers of eggs were inserted in blossom stems, styles and apices of the ovaries. From 30 to 50 per cent of the blossoms of sweet cherry and plum were destroyed, apparently because of disruption of tender tissues by the large numbers of eggs inserted in them; a considerable number of the fruits remaining on the trees were injured by feeding of adults and immature stages of the thrips (Fig. 1).

In this study, we describe and present original data on the bionomics and ecology of Tachygonus erythroxyli Hespenheide, New Species, on Erythroxylum subsessile (Mart.). Thirty individuals of E. subsessile were analysed every two months, from October, 2006 to October, 2007 at the National Park of Restinga de Jurubatiba (PNRJ) Carapebus, Rio de Janeiro, Brazil. Females of T. erythroxyli lay their eggs singly on the upper surface of the host's leaves. The mine of T. erythroxyli is expanded with three bubbles, each one representing one larval instar. These mines occur throughout the year in at least half of the host plants and are markedly more abundant in summer. We obtained three parasitoid species, making a total of 53% of the rate of parasitism. Cirrospilus sp. (Eulophidae) was the most prevalent and represented 88% of the parasitoids. The great abundance of Tachygonus mines, their high frequency in their host plant, and local monophagy of this leaf miner weevil suggest a close association between T. erythroxyli and Erythroxylum subsessile.

The author remarks that the existence of Annelida during the Palæozoic formations is manifested in two conditions. In the one, we have the shelly envelope which invests the order Tubicola, in the form of Seapolites; and in the other, the tracks of the orders Abranchia and Dorsi-branchiata are found impressed on deposits which were, at one time, in a sufficiently soft state to receive the impressions of the wanderings of these animals.Among the strata which have hitherto afforded annelid tracks, those which, in the county of Clare, represent a portion of the equivalents of the Millstone Grit, contain such tracks, in their most perfect state of preservation in great abundance; and these strata also furnish evidence concerning the circumstances which prevailed during their deposition.

Prehistoric Diet

Analysis of the dissected remains of certain small mammals suggests a consistently high ratio of edible meat to live weight. These figures, together with the great abundance of small mammals in natural and culturally modified settings, are combined to support the argument that they may have been important elements in prehistoric diet. Their dietary status may be consistently underestimated because of a number of biases.

Information And Communication

As Developing Nations seek to leverage scarce resources toward the goal of achieving a developed status they must reevaluate past practices and explore available and affordable technologies. Where information and communication infrastructures are weak, use of low-cost, easily distributed technologies have proven effective. Still, many developing nations have failed to incorporate a resource in great abundance, their women, to use these new technologies to greatest advantage. This paper will address the implications of women’s lack of economic and educational parity, and offer examples of how the education of women through the use of information and communication technology can enhance a nation’s gross domestic product (GDP).

The area embraced in this paper consists of that part of Pembrokeshire which lies to the north and north-east of St Bride's Bay. Bounded on the west by St George's Channel and on the north by Cardigan Bay, it extends to the north-east as far as the mouth of the river Teifi, near Cardigan.That part of the country which lies in the immediate neighbourhood of St David's has, through the laborious researches of the late Dr Hicks and others, become well-known to geologists, and may now be regarded as classic ground. The solid geology of this promontory has given rise to much discussion, and has, perhaps, attracted more attention than that of any other part of the Principality. The reason for this great interest is to be sought in the facts that the rocks of this area are of a very great antiquity, and that the sedimentary series contain the remains of some of the earliest organic forms yet found in the earth's crust, whilst the igneous rocks are also displayed in great abundance and variety, and present us, in the words of Sir Archibald Geikie, with “the oldest well-preserved record of volcanic action in Britain.”

Corn is one of the main food products in Mexico. The elaboration of corn-derived products generates wastewater with a high organic load (nejayote). Anaerobic digestion is an indicated treatment for wastewater with high organic loads. The results of this study show that the application of microaeration in the hydrolysis-fermentative reactor increased the percentage of volatile fatty acids (VFA) available in the medium by 62%. The addition of a conductive material, such as granulated activated carbon (GAC), promotes DIET (Direct interspecies electrons transfer) in the methanogenic UASB reactor increasing the methane yield by 55%. Likewise, a great diversity of exoelectrogenic bacteria, with the ability to donate electrons DIET mechanisms, were developed in the GAC biofilm, though interestingly, Peptoclostridium and Clostridium (17.3% and 12.75%, respectively) were detected with a great abundance in the GAC biofilm. Peptoclostridium has not been previously reported as a participant in DIET process.

In a previous paper (8) an organized structure was described in the macronuclei of certain old organisms of Tokophrya infusionum. It was found that the same honeycomb structure appears in great abundance in the macronuclei of overfed organisms. This permitted a better three-dimensional reconstruction of the described structure. Since the defined structure may be experimentally induced, it offers an opportunity for further more detailed studies as to its nature and meaning.
