Parasite biodiversity is underestimated or unknown in many regions, yet information on parasites is critical to understanding ecosystem structure and how this will change into the future. Understanding the diversity and role of parasites is especially important in regions exposed to anthropogenic pressures, such as aquatic ecosystems, as their interactions with other stressors can either exacerbate or mediate negative impacts. Water scarcity in the Brazilian semi-arid has led to a proliferation of reservoirs for human use. These artificial waterbodies host a diversity of taxa, including a large number of fish species; however, fish parasite diversity remains undocumented. This study investigated the parasitological diversity of fishes from reservoirs in the Paraíba and Mamanguape River basins in the Caatinga domain, Brazil – one of the most populated semi-arid regions worldwide. Eight reservoirs were studied, with fish sampled across the two phases of the hydrological cycle (dry and rainy seasons) using gillnets, cast nets, and trawl nets. Endo- and ecto-parasites were identified and enumerated, and parasitological indices (prevalence, intensity, and abundance) were calculated. In total, 1,170 individuals of 21 fish species were examined. Of these individuals, 42% were parasitized with at least one of 54 parasite taxa. We recorded 32 new geographical occurrences of parasites and 23 new fish-parasite interactions, expanding our understanding of ichthyoparasite diversity in the Brazilian semi-arid. Moving forward, it is important to develop knowledge around how anthropogenic changes (e.g., biological invasions, climate, and land use change) influence host-parasite structure and dynamics and ecosystem functioning in these ecosystems.

In Cameroon, >90% of cattle are considered exposed to African animal trypanosomiasis (AAT) infection, with the presence of tsetse rendering cattle husbandry as a very difficult proposition. A systematic review of data on AAT and tsetse from 1990 to 2021 was conducted to develop a national atlas. The review identified 74 relevant scientific documents, with three pathogenic Trypanosoma species (Trypanosoma vivax, T. congolense and T. brucei s.l.) most frequently identified as causing AAT. Trypanosoma grayi, T. theileri, T. simiae and the human African trypanosomiasis causative agent T. brucei gambiense were also identified in a wide range of hosts. The tsetse fly fauna of Cameroon comprises nine species, with Glossina palpalis palpalis and G. fuscipes fuscipes the most widely distributed following their identification in seven and five of the 10 regions, respectively. Two species, Glossina nigrofusca and G. pallicera pallicera appeared to be rare and were restricted to both forest and protected areas. The presence of AAT is associated with the presence of tsetse in the livestock–human–wildlife interface of Cameroon. AAT occurs beyond the tsetse belts of the country where mechanical vectors are abundant. This study provides AAT and tsetse maps to support ongoing interventions in Cameroon.

Submitting grant proposals is becoming an increasingly common expectation—and, in some cases, a requirement—in the discipline of political science as well as other social sciences and the humanities. However, writing a grant with a good chance of success at getting funded is not part of standard mentorship or pedagogy in our discipline. It is a part of the hidden curriculum, where grant-writing skills often are taught informally in working with a principal investigator. This article describes the process and structure of writing a grant to provide a roadmap for scholars to follow in submitting externally funded projects. The article describes an Institutional Review Board–approved survey about mentorship and grant writing and discusses the importance of socialization, professionalization, and administration in supporting scholars in writing and obtaining grants.

This article examines the first German PEN Club (established in 1924) as a semi-formal agent of cultural diplomacy after the First World War. It shows that leading figures in the German PEN negotiated a role in the International PEN which blended PEN's ostensibly non-political literary internationalism with the national interests of the young Weimar Republic. It explores their mutually expedient relationship with the German Foreign Ministry their efforts to influence state cultural diplomacy and their use of the International PEN framework to test alternative visions of international order. The article complicates the notion that PEN was an ‘instrument’ or ‘extended arm’ of foreign policy by underlining the agency of PEN intellectuals and by showing how PEN was part of a wider search for new ways to shape international affairs and find ideological compromise in an era often seen through a dominant lens of confrontation and polarisation.

Can multicellular life be distinguished from single cellular life on an exoplanet? We hypothesize that abundant upright photosynthetic multicellular life (trees) will cast shadows at high sun angles that will distinguish them from single cellular life and test this using Earth as an exoplanet. We first test the concept using unmanned aerial vehicles at a replica moon-landing site near Flagstaff, Arizona and show trees have both a distinctive reflectance signature (red edge) and geometric signature (shadows at high sun angles) that can distinguish them from replica moon craters. Next, we calculate reflectance signatures for Earth at several phase angles with POLDER (Polarization and Directionality of Earth's reflectance) satellite directional reflectance measurements and then reduce Earth to a single pixel. We compare Earth to other planetary bodies (Mars, the Moon, Venus and Uranus) and hypothesize that Earth's directional reflectance will be between strongly backscattering rocky bodies with no weathering (like Mars and the Moon) and cloudy bodies with more isotropic scattering (like Venus and Uranus). Our modelling results put Earth in line with strongly backscattering Mars, while our empirical results put Earth in line with more isotropic scattering Venus. We identify potential weaknesses in both the modelled and empirical results and suggest additional steps to determine whether this technique could distinguish upright multicellular life on exoplanets.

Our research on bias in family formation is rooted in the extant literature of gender and academia but moves beyond discussion of the “leaky-pipeline” metaphor to explore less frequently addressed issues including pregnancy loss, illness, lactation, and challenges faced by academic parents who are the partners of those who have given birth. We explore the lower-order processes that inform the gap in professional achievement between men and women in political science specifically and in academia more broadly. In turn, these lower-order processes manifest as more observable higher-order outcomes such as the disparate rates of tenure and promotion. We conducted a 100-question survey from November 2017 through July 2019 involving more than 300 respondents. Through analysis of open-ended survey responses, we identified a common theme uniting faculty experiences at a range of universities: family formation and parenting can be isolating processes for academics, and there often is a gross lack of both formal and informal support within universities, which creates the potential for setbacks in both personal and professional life. We highlight the challenges confronting academic parents—especially women—and suggest potential avenues to a more inclusive and balanced approach to academia.
