AbstractConservation efforts have led to the recovery of the endangered mountain gorilla populations. Due to their limited potential for spatial expansion, population densities increased, which may alter the epidemiology of infectious diseases. Recently, clinical gastrointestinal illnesses linked to helminth infections have been recorded in both gorilla populations. To understand drivers and patterns of helminth infections we quantified strongylid and tapeworm infections across both Virunga Massif and Bwindi populations using fecal egg counts. We assessed the impact of age, sex, group size, season and spatial differences used as a proxy, which reflects observed variation in the occurrence of gastrointestinal problems, vegetation types, gorilla subpopulation growth and associated social structure on helminth infections. We revealed striking geographic differences in strongylid infections with higher egg counts mostly in areas with high occurrences of gastrointestinal disease. Increased helminth egg counts were also associated with decreasing group size in some areas. Observed spatial differences may reflect mutual effects of variations in subpopulation growth rates, gorilla social structure, and vegetation associated with altitude across mountain gorilla habitat. Helminth infection intensities in Virunga gorillas were lowest in the youngest and the oldest animals. Elucidating parasite infection patterns of endangered species with low genetic diversity is crucial for their conservation management.

The Impact

The four most important King Kong films (1933, 1976, 2005, and 2017) contain religious sentiments that are related to the numinous and mysterious fear of Nature and death that gives meaning to life, and to the institutionalization of society. In this way, as observed in the films, the Society originated by religion is a construction against Nature and Death. Based on these hypotheses, the objective of this work is to (a) show that the social structure of the tribal society that lives on Skull Island is reinforced by the religious feelings that they profess towards the Kong divinity, and (b) reveal the impact that the observation of the generalized alterity that characterizes the isolated tribal society of the island produces on Western visitors—and therefore, on film viewers. The article concludes that the return to New York, after the trip, brings an unexpected guest: the barbarism that is installed in the heart of civilization; that the existing order is reinforced and the society in crisis is renovated; and that the rationality subject to commercial purposes that characterizes modernity has not been able to escape from the religiosity that nests in the depths of the human soul.

The Impact

Colonization and decolonization are theorized at the intersection of Critical Junctures Theory and Power Basis Theory. This framework allows human agency to be conceptualized at micro-, meso-, and macro-levels, where individuals act on behalf of collectives. Their actions decide whether critical junctures in history (moments of potential for substantive change) result in continuity (no change), anchoring (continuity amid change with new elements), or rupture. We apply this framework to European colonization of the world, which is the temporal scene for contemporary social justice. Several critical junctures in New Zealand history are analyzed as part of its historical trajectory and narrated through changes in its symbology (system of meaning) and technology of state, as well as the identity space it encompasses (indigenous Māori and British colonizers). The impact of this historical trajectory on the social structure of New Zealand, including its national identity and government, is considered and connected to the overarching theoretical framework.

The Impact

In the research presented in this paper, we analyse whether the structure of the political cleavage system in Iceland has changed since 1983, as well as whether the impacts of party-voter linkages and the social structure of the vote have changed between 1983 and 2016/2017. Based on official data and the Icelandic National Election Study (ICENES), we find that the rural-urban cleavage and left-right cleavage, which are reflected in party polarisation on the left-right spectrum, are as important today as previously. Our main results regarding the impacts of party-voter linkages and the social-structure of the vote is that the core bonds of party identification, left-right distances and the social structure of the vote have weakened over time, whereas the impact of party sympathy has become stronger. This, we argue, reflects that while there has been a gradual change in the impact of party-voter linkages and the social structure of the vote, opening up a space for new parties to succeed, the political cleavage system has remained intact. The major change has thus occurred in the bond between voters and parties and not in the structure of party competition in Iceland.

Pm2.5 Concentration

As an important field for human activities, cities play a critical role in PM2.5 reductions. Among the determinants for PM2.5 concentration, technological progress is considered to exhibit significant inhibitory effects. Although most extant research has focused on energy technologies or total factor productivity, due to limitations in data and methods, few scholars have focused on emission reduction technological changes at a city-level scale. Therefore, based on the combination of k-means clustering and the log-mean Divisia index method, this study estimates and explores the impact of PM2.5 emission reduction technology (PME) on the temporal changes and spatial differences of 262 Chinese cities’ PM2.5 concentration during 2003–2017. The findings show the following: (1) although the results based on econometric methods indicate that emission reduction technological changes decreased China’s city-level PM2.5 concentration, there were turning points in the yearly impacts, indicating that the improvements to emission reduction efficiency were not stable; (2) compared with PME, energy intensity played a more stable role in PM2.5 emissions reductions, implying that the improvement of energy efficiency was still very important in controlling PM2.5 concentrations; (3) based on the classified groups after clustering, most cities’ PME contributed to negative differences, but the PME of a small number of cities was very weak to largely lower the average level of their group; and (4) distributions of the spatial decomposition of the three classified groups were stable in the period of 2003–2017, implying that the catch-up and transcendence effects of PME within the group were limited. Thus, policymakers should focus on the impact of different policies on PME differences between cities.

The Impact

Soils have a profound impact on the causation and geographical distribution of human disease and well-being. However, because of the multifactorial causes of illnesses, the impact of soils on health needs to be considered in light of the environment in its fullest sense. Since the nineteenth century, medical cartography has served as an epidemiological tool for investigating the links between soils and human well-being. Using examples, particularly the problems of soil-transmitted helminth infections, and iodine and selenium deficiency diseases, this paper shows how maps have been used to identify problem areas, stimulate the development of aetiological hypotheses, help in the planning and management of public health problems, and assess the impact of any beneficial strategies.

Abstract— Little is known about the effects of habitat fragmentation on the patterns of genetic diversity and genetic connectivity of species in the remaining tropical forests of Southeast Asia. This is particularly evident in Cebu, a Philippine island that has a long history of deforestation and has lost nearly all of its forest cover. To begin filling this gap, data from 13 microsatellite loci developed for Tetrastigma loheri (Vitaceae), a common vine species in Philippine forests, were used to study patterns of genetic diversity and genetic connectivity for the four largest of the remaining forest areas in Cebu. Evidence of relatively high levels of inbreeding was found in all four areas, despite no evidence of low genetic diversity. The four areas are genetically differentiated, suggesting low genetic connectivity. The presence of inbreeding and low genetic connectivity in a commonly encountered species such as T. loheri in Cebu suggests that the impact of habitat fragmentation is likely greater on rare plant species with more restricted distributions in Cebu. Conservation recommendations for the remaining forest areas in Cebu include the establishment of steppingstone corridors between nearby areas to improve the movement of pollinators and seed dispersers among them.
