A global survey of the societal benefits of trophy hunting in Africa

African trophy hunting is controversial. Central to the debate on this practice is whether it may be justified by any broader provisions to African society. These typically include meat supply to poor communities, problem animal control, and the funding of conservation and community development. The societal role of African hunting is as contested as the practice itself, with proponents advocating for the benefits of hunting, while critics point to these being inadequate. Little is known about the role of location and demography in the debate on hunting benefits. Here we circulated an anonymous online survey through our international networks. We asked respondents to indicate which (if any) benefits they thought may justify the practice and whether they supported African trophy hunting, or not. We also collected data on respondent geographic location, age, gender, and employment within conservation. The 5755 responses were analysed using multiple correspondence analysis and provided strong evidence for an association between the level of support/rejection of trophy hunting and potential benefits that were perceived to justify the practice. Funding of wildlife conservation through hunting was the most frequently selected benefit, even among many respondents with a neutral or slightly negative view toward trophy hunting as a practice. Respondents strongly opposed to trophy hunting were more likely to reject all societal benefits of hunting. There was some divergence in views between Africa-based respondents, and those outside of Africa. We suggest that any policy development on African trophy hunting be required to incorporate the views of all African stakeholders

Patterns of in situ Mineral Colonization by Microorganisms in a ~60°C Deep Continental Subsurface Aquifer

The microbial ecology of the deep biosphere is difficult to characterize, owing in part to sampling challenges and poorly understood response mechanisms to environmental change. Pre-drilled wells, including oil wells or boreholes, offer convenient access, but sampling is frequently limited to the water alone, which may provide only a partial view of the native diversity. Mineral heterogeneity demonstrably affects colonization by deep biosphere microorganisms, but the connections between the mineral-associated and planktonic communities remain unclear. To understand the substrate effects on microbial colonization and the community response to changes in organic carbon, we conducted an 18-month series of in situ experiments in a warm (57°C), anoxic, fractured carbonate aquifer at 752 m depth using replicate open, screened cartridges containing different solid substrates, with a proteinaceous organic matter perturbation halfway through this series. Samples from these cartridges were analyzed microscopically and by Illumina (iTag) 16S rRNA gene libraries to characterize changes in mineralogy and the diversity of the colonizing microbial community. The substrate-attached and planktonic communities were significantly different in our data, with some taxa (e.g., Candidate Division KB-1) rare or undetectable in the first fraction and abundant in the other. The substrate-attached community composition also varied significantly with mineralogy, such as with two Rhodocyclaceae OTUs, one of which was abundant on carbonate minerals and the other on silicic substrates. Secondary sulfide mineral formation, including iron sulfide framboids, was observed on two sets of incubated carbonates. Notably, microorganisms were attached to the framboids, which were correlated with abundant Sulfurovum and Desulfotomaculum sp. sequences in our analysis. Upon organic matter perturbation, mineral-associated microbial diversity differences were temporarily masked by the dominance of putative heterotrophic taxa in all samples, including OTUs identified as Caulobacter, Methyloversatilis, and Pseudomonas. Subsequent experimental deployments included a methanogen-dominated stage (Methanobacteriales and Methanomicrobiales) 6 months after the perturbation and a return to an assemblage similar to the pre-perturbation community after 9 months. Substrate-associated community differences were again significant within these subsequent phases, however, demonstrating the value of in situ time course experiments to capture a fraction of the microbial assemblage that is frequently difficult to observe in pre-drilled wells

Divergent views on trophy hunting in Africa, and what this may mean for research and policy

Over the past decade, trophy hunting in Africa has seen increased public and scientific interest. Much of that attention has come from outside of Africa, with little emphasis on local views. We circulated an online survey through international networks to explore demographic and regional differences in opinion regards support for African trophy hunting, trophy import bans, and outside funding of conservation estates supported by hunting. We received ∼5700 responses and found that location, demography, and conservation background influenced opinion. African and North American respondents showed (significantly) more support for trophy hunting than respondents from Europe or other areas, as did respondents with conservation backgrounds. Unlike North Americans, Africans supported external subsidies of wildlife areas presently funded by hunting. Many factors affected opinions on African hunting, but respondent location played a major role. Realistic policy on African trophy hunting should thus integrate African perspectives, in particular those of rural communities

Wives’ part-time employment and marital stability in Great Britain, West Germany and the United States

Many hail wives’ part-time employment as a work—family balance strategy, but theories offer competing predictions as to the effects of wives’ employment on relationship stability. We use panel data to test these competing hypotheses among recent cohorts of first-married couples in Great Britain, West Germany 1 and the United States. We find effects of wives’ employment on marital stability var y across the countries. In West Germany with its high-quality part-time employment, couples where the wife works part time are significantly more stable. In the more liberal British and US labour markets, neither wives’ part- nor full-time employment significantly alters divorce risk. In the United States, however, mothers working part time have significantly lower divorce risk. West German and British husbands’ unemployment proves more detrimental to marital stability than wives’ employment. These results highlight the importance of the socioeconomic context in structuring the optimal employment participation of both partners
