A survey of the archeological and paleontological literature allowed a compilation of Holocene records of mammals in Nebraska. This survey identified Holocene records from 338 sites in 62 of the 93 Nebraska counties. These counties were located throughout state, but there was a concentration of sites in southwestern Nebraska where there were 27 fossil sites in Frontier County and 22 in Harlan County. Fossils sites were underrepresented in the Sand Hills region. Records of fossil mammals covered the entire Holocene period from 13,000 years ago until AD 1850. A minimum of 57 species (with eight additional species potentially present) representing six orders of mammals were represented in the compilation—four species of Lagomorpha, four species of Soricomorpha, 17 species of Carnivora (with three additional species potentially present), one species of Perissodactyla, six species of Artiodactyla, and 25 species of Rodentia (with five additional species potentially present). The remains of bison were found at 276 sites, which was more than for any other species in the state. Additional species that formed the main portion of the diet of Native Americans were the next most abundant in the fossil record—deer, pronghorn, and wapiti. That these food species dominated in the Holocene record was to be expected because fossils were recovered primarily from archeological sites.

A thorough survey of the members of Solanaceae was carried out in Sirumalai Hills and occurrences of six additional species of Solanaceae hitherto not reported from Sirumalai Hills is reported here. Of these, Solanum americanum Mill. var. odishense Kalidass & P. Murugan turned out to be a new report for the state of Tamil Nadu and Solanum pseudocapsicum L. an addition to Solanaceae of Eastern Ghats. A brief description with photographs and other relevant notes is provided for each species for easy identification.

ABSTRACT The bony-tongue fishes, Osteoglossomorpha, have been the focus of a great deal of morphological, systematic, and evolutionary study, due in part to their basal position among extant teleostean fishes. This group includes the mooneyes (Hiodontidae), knifefishes (Notopteridae), the abu (Gymnarchidae), elephantfishes (Mormyridae), arawanas and pirarucu (Osteoglossidae), and the African butterfly fish (Pantodontidae). This morphologically heterogeneous group also has a long and diverse fossil record, including taxa from all continents and both freshwater and marine deposits. The phylogenetic relationships among most extant osteoglossomorph families are widely agreed upon. However, there is still much to discover about the systematic biology of these fishes, particularly with regard to the phylogenetic affinities of several fossil taxa, within Mormyridae, and the position of Pantodon. In this paper we review the state of knowledge for osteoglossomorph fishes. We first provide an overview of the diversity of Osteoglossomorpha, and then discuss studies of the phylogeny of Osteoglossomorpha from both morphological and molecular perspectives, as well as biogeographic analyses of the group. Finally, we offer our perspectives on future needs for research on the systematic biology of Osteoglossomorpha.

This chapter reviews and extends the discussion of slavery and race that runs through previous chapters, starting with Paxton’s Case. Patriots and their critics alike pointed out the tension between colonial rights claims grounded in the state of nature, and colonial slavery. Portrayals of Native American innocence and virtue in the state of nature coexisted with accounts of their savagery, successfully repelled by the early settlers whose descendants, it was claimed, consequently held rights to property and self-government independently from Britain, which failed to finance or protect them. Optimistic, self-critical, racist, and abolitionist revolutionaries, all fearful of American degeneracy and corruption, used state of nature depictions of both abhorrent and justifiable slavery, and noble and savage Native Americans, to advocate for their vision for the new United States. This chapter reviews the whole spectrum of such uses of the state of nature, including the landmark Somersett’s Case and Mohegan Case.

A summary of the numbers of species of the 83 families of Hymenoptera recorded in Canada is provided. In total, 8757 described species are recorded compared to approximately 6000 in 1979, which is a 46% increase. Of the families recognized in 1979, three have been newly recorded to Canada since the previous survey: Anaxyelidae (Anaxyleoidea), Liopteridae (Cynipoidea), and Mymarommatidae (Mymarommatoidea). More than 18,400 BINs of Canadian Hymenoptera are available in the Barcode of Life Data Systems (Ratnasingham and Hebert 2007) implying that nearly 9650 undescribed or unrecorded species of Hymenoptera may be present in Canada (and more than 10,300 when taking into account additional species that have not been DNA barcoded). The estimated number of unrecorded species is very similar to that of 1979 (10,637 species), but the percentage of the fauna described/recorded has increased from 36% in 1979 to approximately 45% in 2018. Summaries of the state of knowledge of the major groups of Hymenoptera are presented, including brief comments on numbers of species, biology, changes in classification since 1979, and relevant taxonomic references.

A New Species

At the time the genus Attacobius Mello-Leitão, 1925 was first acknowledged as a member of the subfamily Corinninae, Corinnidae, by Platnick & Baptista (1995), only three species were recognized. Since then, that number has increased to 15 currently valid species (Bonaldo & Brescovit 1998; 2005; Pereira-Filho et al. 2018). Recently we had the opportunity to discover an additional species of Attacobius, collected in association with fire ants of the genus Solenopsis Westwood in the State of Goiás, Midwest Brazil, a region that harbors a large portion of the Brazilian Cerrado, one of the most threatened savannas in the planet. Attacobius lavape n. sp., described below, appears to belong to the same group of species as A. verhaaghi Bonaldo & Brescovit, 1998 and A. lamellatus Bonaldo & Brescovit, 2005, since these three species share, in the male palp, the presence of an unsclerotized median lobe on the retrolateral tibial apophysis (Figs 9, 11). 

The Holocene record of environmental changes in the ‘Stagno di Maccarese’ marsh (Tiber river delta, central Italy)

Ird Events

The stratigraphic study of the Stagno di Maccarese, carried out on the sediments exposed in about 7 km of trenches excavated in an area of approximately 1.5 km2, has shown that in the course of the Holocene many environmental variations have taken place. The complex evolution of the marsh is demonstrated by the variations in water salinity and the presence of erosion surfaces and soils between the sediments. In the early Holocene, the area studied was an isolated marsh with water having variable salinity, and it was only about 6000 cal. yr BP that it was encompassed in the system of inner delta marshes. In the delta environment, the water of the marsh was oligohaline until about 9th–8th centuries bc, brackish from 9th–8th centuries bc to about 600 yr BP, and later oligohaline until the 19th century drainage. A number of environmental variations are connected with local phenomena, such as erosion of the beach ridges and Tiber floods, but the others can be correlated chronologically with climatic events recorded at regional and global scale. The millennial variations seem to be connected with changes in insolation, while abrupt variations can be correlated chronologically with the IRD events dated at 8200, 5900, 4200, 2800, 1400 and 500 cal. yr BP.
