Background Anosteira pulchra is one of two species of the obligately-aquatic freshwater clade Carettochelyidae (pig-nosed turtles) from the Eocene of North America. Anosteira pulchra is typically rare in collections, and their distribution is poorly documented. The Uinta Formation [Fm.] contains a diverse assemblage of turtles from the Uintan North American Land Mammal Age. Whereas turtles are abundantly preserved in the Uinta Fm., A. pulchra has been reported only from a few specimens in the Uinta C Member. Methods We describe new records of Anosteira pulchra from the Uinta Basin and analyze the distribution of 95 specimens from multiple repositories in the previously published stratigraphic framework of the middle and upper Uinta Fm. Results Here we report the first records of the species from the Uinta B interval, document it from multiple levels within the stratigraphic section and examine its uncommon appearance in only approximately 5% of localities where turtles have been systematically collected. This study details and extends the range of A. pulchra in the Uinta Fm. and demonstrates the presence of the taxon in significantly lower stratigraphic layers. These newly described fossils include previously unknown elements and associated trace fossils, with new anatomical information presented. This study provides insight into the taxonomy of Anosteira spp. in the middle Eocene, and suggests the presence of a single species, though no synonymy is defined here due to limits in Bridger material.

Insight Into

The two versions of the autobiography that Nicholas Said published offer insight into 19th-century conditions in five continents as well as insight into life as a child, slave, manservant, and teacher. As a child in the 1830s, Said was enslaved in Borno, marched across the Sahara Desert, and passed from hand to hand in North Africa and the Middle East. After serving as a slave in various societies, Said was freed by a Russian aristocrat in the late 1850s after accompanying the aristocrat in question to various parts of Europe. In the 1850s, Said also traveled as a manservant for a European traveler to South and North America. Ultimately he settled in the United States, where he authored two versions of his autobiography, served as a teacher and soldier, got married, and disappeared from sight. This article compares the two versions of the autobiography that Said published, provides an overview of Said’s life, charts the development of scholarly works on Said, and draws attention to the primary sources related to the study of Said and his autobiography.

Insight Into

This Chapter explores the emergence of dense networks of migrant smuggling in response to the efforts of the Ottoman state to enforce the ban on Armenian migration to North America. It shows how these networks formed very shortly after the imposition of the ban, and until the lifting of the ban in 1908, assisting the travel of thousands of Armenian migrants from their home communities in the Anatolian interior to various port cities on the Black and Mediterranean Sea coasts and on to steamships bound for European transit ports. It also provides insight into the diverse set of actors that comprised these networks and coordinated them across vast stretches of time and space. The Chapter also draws parallels between the dynamics that drove clandestine migration in the late Ottoman period with those that drive the same phenomenon in the present.

Context According to the tens rule, 10% of introduced species establish themselves. Aims We tested this component of the tens rule for amphibians and reptiles globally, in Europe and North America, where data are presumably of good quality, and on islands versus continents. We also tested whether there was a taxonomic difference in establishment success between amphibians and reptiles. Methods We examined data comprising 206 successful and 165 failed introduction records for 161 species of amphibians to 55 locations, and 560 successful and 641 failed introduction records for 469 species of reptiles to 116 locations around the world. Key results Globally, establishment success was not different between amphibians (67%) and reptiles (62%). Both means were well above the 10% value predicted by the tens rule. In Europe and North America, establishment success was lower, although still higher than 10%. For reptiles, establishment success was higher on islands than on continents. Our results question the tens rule and do not show taxonomic differences in establishment success. Implications Similar to studies on other taxa (birds and mammals), we found that establishment success was generally above 40%. This suggests that we should focus management on reducing the number of herptile species introduced because both reptiles and amphibians have a high likelihood of establishing. As data collection on invasions continue, testing establishment success in light of other factors, including propagule pressure, climate matching and taxonomic classifications, may provide additional insight into which species are most likely to establish in particular areas.

We provide an initial insight into the occurrence and characteristics of animal-visitor interactions (AVIs) involving captive wild animals within zoos and aquaria. Using information provided online via official public websites of modern zoos and aquaria, we found that AVIs were provided by the majority of facilities. Our study revealed that a variety of AVI types were being offered. Globally, petting captive wild animals was the most prevalent AVI type advertised (n = 1241 observations, 43% (534) of facilities) and Mammalia was the most advertised taxonomic class (n = 5142; 53% (2739)). We found certain AVI types that were more commonly offered than predicted. These were opportunities to: (1) Hand feed captive wild animals in Asia, North America and Oceania; (2) ride wild animals in Europe and North America; (3) walk with or swim through wild animal enclosures in Asia; and (4) walk with wild animals in Asia and Europe. Given the global prevalence of AVIs in modern zoos and aquaria, and an apparent lack of animal welfare focused research, we provide recommendations to help effectively balance and manage captive wild animal welfare with other primary interconnected goals.

Two new species of the subterranean amphipod genus Stygobromus (Amphipoda: Crangonyctidae) from Siberia, with new data on Stygobromus pusillus (Martynov) and remarks on morphology and biogeographic relationships

Two new species of the subterranean amphipod genus Stygobromus are described from groundwater habitats in Siberia: Stygobromus mikhaili n. sp. from a spring in the Central Altay Mountains and Stygobromus anastasiae n. sp. from two non-freezing springs in South Pribaikalye in the Irkutsk area. Additional taxonomic details of the previously described S. pusillus (Martynov) from Teletskoye Lake, also in Central Altay, are illustrated based on syntype material. Utilization of SEM has revealed a tiny structure on antenna 2 that appears to be a new character, and may prove useful in future analyses. Descriptions of the two new species raise the total number of described species in the genus Stygobromus to 134, but four or possibly five have been found in the Palearctic region outside North America. However, it is likely that continued exploration of subterranean groundwater habitats in Siberia and other parts of the Palearctic will reveal additional new species of Stygobromus and provide more insight into the origin and geographic distribution of this large, northern hemisphere, subterranean freshwater amphipod genus. Careful evaluation of taxonomic affinities of the new species and comparison with previously described congeners should provide further insight into the biogeographic history of Stygobromus.

ABSTRACTThe social and economic position of lodgers in Europe and North America has attracted considerable scholarship, yet the financial and interpersonal relationships between lodgers and boarders and their hosts in working-class homes is somewhat underdeveloped. This article examines patterns of lodging and boarding in working-class homes in Scotland between 1861 and 1911, focusing upon multiple layers of connection between paying guests and householders. This article demonstrates that connections had national and ethnic roots, and that taking in lodgers and boarders was of prime cultural and economic importance for many. The ability to offer space played a crucial role in the social and economic status of single, separated and widowed women, and this article offers an insight into the sometimes troubled relationships between landladies and their tenants.
