This study examines postmarital residence patterns at the Windover site, an Early Archaic occupation located in east-central Florida. Residence patterns are assessed using a population genetics model based on isolation by distance and migration matrix methods. Variation in nonmetric dental traits is examined among a group of 40 adult males and 43 adult females. The sex with the higher within-group variance is considered the more mobile sex, thereby providing a possible reflection of residential patterns. Results indicate that females are almost twice as variable as males, thus suggesting patrilocality. However, this result is not statistically significant at the .05 probability level. Additional lines of evidence are assessed in conjunction with dental data. Specifically, ethnographic data indicate that subsistence and sexual division of labor are important factors related to social organization, including residence. Although these lines of evidence can be used to support the dental data and patrilocality, they are not conclusive. Future studies of activity patterns, disease, mortuary remains, and material culture may help to clarify the issue of postmarital residence patterns at Windover.

Lines Of Evidence

This study demonstrates that gender imbalance can explain certain problematic artifact assemblages. Typical warfare refugee populations include more women than men because more men than women are killed in conflicts. This paper proposes that predominantly female warfare refugees altered the material culture of the Grasshopper region of Arizona during the thirteenth and fourteenth centuries. This thesis is supported by the temporal congruity of multiple lines of evidence, including evidence outside of the region for the violent deaths of more men than women and evidence within the region for female- dominated burials, immigration, and gendered continuities and discontinuities in material culture.

Abstract The rs1344706 polymorphism in ZNF804A is robustly associated with schizophrenia and schizophrenia is, in turn, associated with abnormal non-rapid eye movement (NREM) sleep neurophysiology. To examine whether rs1344706 is associated with intermediate neurophysiological traits in the absence of disease, we assessed the relationship between genotype, sleep neurophysiology, and sleep-dependent memory consolidation in healthy participants. We recruited healthy adult males with no history of psychiatric disorder from the Avon Longitudinal Study of Parents and Children (ALSPAC) birth cohort. Participants were homozygous for either the schizophrenia-associated ‘A’ allele (N=22) or the alternative ‘C’ allele (N=18) at rs1344706. Actigraphy, polysomnography (PSG) and a motor sequence task (MST) were used to characterize daily activity patterns, sleep neurophysiology and sleep-dependent memory consolidation. Average MST learning and sleep-dependent performance improvements were similar across genotype groups, albeit more variable in the AA group. During sleep after learning, CC participants showed increased slow-wave (SW) and spindle amplitudes, plus augmented coupling of SW activity across recording electrodes. SW and spindles in those with the AA genotype were insensitive to learning, whilst SW coherence decreased following MST training. Accordingly, NREM neurophysiology robustly predicted the degree of overnight motor memory consolidation in CC carriers, but not in AA carriers. We describe evidence that rs1344706 polymorphism in ZNF804A is associated with changes in the coordinated neural network activity that supports offline information processing during sleep in a healthy population. These findings highlight the utility of sleep neurophysiology in mapping the impacts of schizophrenia-associated common genetic variants on neural circuit oscillations and function.

The data on activity pattern and time budget of Swamp deer (Rucervus duvauceli duvauceli) were collected through instantaneous scan sampling from Dudhwa National Park, Uttar Pradesh, India Diurnal activity pattern of Swamp deer showed marked reduction in resting in winter as compared to summer. In winter resting in adult males showed polymodal pattern with peaks occurring at different hours of the day and continued throughout the day without any break. Feeding of adult females in winter and summer seasons showed a polymodal pattern with peaks occurring at different hours of the day without break. In yearling males feeding and resting was observed to occur throughout the day during winter season with peaks occurring between 11:00 to 12:00 hours. Yearling females showed continuous feeding throughout the day with peaks in different times in both the seasons. The seasonal distribution of activity patterns of the fawns showed that feeding was slightly more in summer as compared to winter. In time budget, of the expenditure on different activities, resting accounted for 63.77% and feeding 24.70%. In both the seasons resting was the major portion of their activity. Analysis showed that in all age and sex categories of Swamp deer in the Dudhwa NP, resting dominated on all other activities. The observation on endangered Swamp deer indicates synchronization in activity only in the feeding in the morning and evening hours and resting throughout the day.

Hydromys Chrysogaster

The Water Rat Hydromys chrysogaster is Australia's largest amphibious rodent, occupying freshwater rivers, lakes, and coastal and estuarine habitats throughout the continent (Watts and Aslin 1981). Little is known of the species' social organisation or use of space in the wild although Harris (1978) suggested that adults might be intrasexually aggressive. The home ranges of all sex and age classes overlap to some extent but home ranges of adults of the same sex appear to overlap less (Harris 1978). Adult males occupy the largest home ranges which overlap those of one or more females. In captivity individuals kept in groups form hierarchies in which only the dominant females usually breed successfully (Olsen 1982). Fighting occurs primarily among males, with the highest incidence of injuries observed at the beginning of the main September-March breeding season (Olsen 1980, 1982). The results of trapping studies indicate that population density may vary considerably, with the greatest numbers of animals typically occupying man-modified habitats such as irrigation channels or fish farms (McNally 1960, Watts and Aslin 1981, Smales 1984). Aggressive behaviour appears to be related to pelage colour (phenotype) and population density; the higher the density the greater the number of injured individuals (Olsen 1980).

The association between NOTCH4 and schizophrenia has been repeatedly reported. However, the results from different genetic studies are inconsistent, and the role of NOTCH4 in schizophrenia pathogenesis remains unknown. Here, we provide convergent lines of evidence that support NOTCH4 as a schizophrenia risk gene. We first performed a meta-analysis and found that a genetic variant (rs2071287) in NOTCH4 was significantly associated with schizophrenia (a total of 125 848 subjects, p=8.31×10−17), with the same risk allele across all tested samples. Expression quantitative trait loci (eQTL) analysis showed that rs2071287 was significantly associated with NOTCH4 expression (p=1.08×10−14) in human brain tissues, suggesting that rs2071287 may confer schizophrenia risk through regulating NOTCH4 expression. Sherlock integrative analysis using a large-scale schizophrenia GWAS and eQTL data from human brain tissues further revealed that NOTCH4 was significantly associated with schizophrenia (p=4.03×10−7 in CMC dataset and p=3.06×10−6 in xQTL dataset), implying that genetic variants confer schizophrenia risk through modulating NOTCH4 expression. Consistently, we found that NOTCH4 was significantly downregulated in brains of schizophrenia patients compared with controls (p=2.53×10−3), further suggesting that dysregulation of NOTCH4 may have a role in schizophrenia. Finally, we showed that NOTCH4 regulates proliferation, self-renewal, differentiation and migration of neural stem cells, suggesting that NOTCH4 may confer schizophrenia risk through affecting neurodevelopment. Our study provides convergent lines of evidence that support the involvement of NOTCH4 in schizophrenia. In addition, our study also elucidates a possible mechanism for the role of NOTCH4 in schizophrenia pathogenesis.

First Time

Born from the fields of Islamic art and architectural history, the archaeological study of the Islamic societies is a relatively young discipline. With its roots in the colonial periods of the late 19th and early 20th centuries, its rapid development since the 1980s warrants a reevaluation of where the field stands today. This Handbook represents for the first time a survey of Islamic archaeology on a global scale, describing its disciplinary development and offering candid critiques of the state of the field today in the Central Islamic Lands, the Islamic West, Sub-Saharan Africa, and Asia. The international contributors to the volume address such themes as the timing and process of Islamization, the problems of periodization and regionalism in material culture, cities and countryside, cultural hybridity, cultural and religious diversity, natural resource management, international trade in the later historical periods, and migration. Critical assessments of the ways in which archaeologists today engage with Islamic cultural heritage and local communities closes the volume, highlighting the ethical issues related to studying living cultures and religions.

SummaryThe estimation of genetic similarity from correspondence of surnames (isonymy) allows investigation of historical population structure. This study uses surname data from seven isolates located along the west coast of Ireland during the 1890s to assess geographic and historic influences on population structure. Observed genetic variation among populations shows a close fit with the expected isolation by distance model, with estimated parameters of isolation and migration being similar to those obtained in other studies of isolated populations. Local genetic variation appears to be due primarily to the size of the local breeding population, with deviations being explained in terms of recent emigration.

The activity patterns of a resident population of 15 feral cats (Felis catus L.) on New Zealand farmland were investigated from March 1984 until February 1987 by radiotelemetry. Females could be divided into two separate groups: (1) those denning in barns and (2) those denning in the swamp and willows. Females denning in barns were mainly nocturnal except in spring and summer when rearing kittens. Barn cats moved significantly further between dusk and dawn, except in autumn-winter, than those denning in swamp and willows which were active over 24 h. When not breeding, related females occupied the same barn. In both groups, the home range of female relatives overlapped. Males ranged over all habitats, and dominant adult males moved significantly further and had larger home ranges than other males in all seasons, except in summer when they rested, avoiding hot summer days. Only adult males were active during the day in spring and autumn-winter. The importance of a Zeitgeber in synchronising cat activity with that of the prey is examined. The significance of female den site is discussed in relation to proximity of food, predators, social behaviour and male defence.

This article presents new excavation results from three oval or apsidal houses discovered at the site of Maydos-Kilisetepe (ancient Madytos), which is located near the coast of the Hellespont on the Gallipoli peninsula. The houses date to the late eighth to early sixth century bc. The material from Maydos is evaluated in comparison with the nearby site of Troy (Ilion) and situated within the wider context of developments in the north-eastern Aegean region during the Late Geometric to Early Archaic periods. From the mid-eighth to the mid-seventh century, a cultural koine existed in the north-eastern Aegean, shown by the strong similarities in material culture among the sites in the region. Troy was most probably a large regional centre, while Maydos functioned as a smaller settlement within this network. The power and influence of this koine declined or was replaced in the mid-seventh century, when there was a sudden influx of Ionian-style ceramics at Maydos, around the same time that Troy experienced a destruction. The patterns of cultural interactions changed with the establishment of Greek (primarily Ionian and Athenian) colonies on both sides of the Hellespont during the second half of the seventh to the early sixth century.

Abstract Observations of Chinese pangolin (Manis pentadactyla) in the wild are extremely rare and challenging because of their nocturnal and cryptic activity patterns and low population density. The present article reported the first field observation in eastern Taiwan, from October 4, 2012 to June 16, 2016, on the reproductive behavior of the Chinese pangolin based on the monitoring of a female (LF28) using radiotelemetry and camera traps. During this period, LF28 aged from 1 to 4.5-years old and gave two single-births, both took place in early December, at 3 and 4 years old, respectively. We recorded the entire 157 days of the first nursing period from parturition to maternal separation. For the second infant, the gestation period was estimated to be around 150 days based on the evidence that the pregnancy started in early Jul. 2015 and the offspring was born on Dec. 9, 2015. During the entire nursing period, LF28 frequently moved the offspring from one nursing burrow to another staying various durations ranging from 1 day to more than 35 days, and almost all (= 15/16) of these burrows were located in the core (MCP75) of LF28’s home range. Started from the month of parturition and lasting throughout the whole nursing period, different adult males constantly visiting the nursing burrows were recorded. Mating behavior was recorded once outside the burrow in March, which provided evidence of the occurrence of post-partum estrus in this species. Delay implantation was proposed based on the observation of a several months lag between copulation and the estimated pregnancy initiation date. The present study demonstrated the advantage of using remote technologies to learn the life history of resting fossorial species.
