Global biogeography of ant social parasites: Exploring patterns and mechanisms of an inverse latitudinal diversity gradient

Kyle Gray & Christian Rabeling
Aim: One of the most consistent global biogeographic patterns is the latitudinal diversity gradient where species richness peaks within the equatorial tropics and decreases towards the poles. Here, we explore the global biogeography of socially parasitic ants, which comprises the most diverse group of social parasites in the Hymenoptera. We test the biogeographic hypothesis that ant social parasites are distributed along an inverse latitudinal diversity gradient by peaking in diversity outside of the equatorial tropics....

Functional diversity of farmland bees across rural-urban landscapes in a tropical megacity

Gabriel Marcacci, Ingo Grass, Vikas S Rao, Shabarish Kumar S, K.B. Tharini, Vasuki Belavadi, Nils Nölke, Teja Tscharntke & Catrin Westphal
Urbanization is a major threat to biodiversity and food security, as expanding cities, especially in the Global South, increasingly compete with natural and agricultural lands. However, the impact of urban expansion on agricultural biodiversity in tropical regions is overlooked. Here we assessed how urbanization affects the functional response of farmland bees, the most important pollinators for crop production. We sampled bees across three seasons in 36 conventional vegetable-producing farms spread along an urbanization gradient in...

Comparison of high-resolution SIMS profiles with maximum resolution IRMS stable isotope data

Tobias Kluge , Philipp Holz , Elisabeth Eiche , Thomas Neumann , Alexander Land , Maximilian Schuh , Mario Trieloff & Axel K. Schmitt
High-resolution speleothem paleoclimate records with annual to seasonal resolution are helpful for detailed analysis of climatic changes with limited duration (e.g., volcanic climate impacts), but also for longer-duration events (e.g., at 8.2 ka or 4.2 ka). A high resolution paleoclimate data set is also mandatory for meaningful comparison with archaeological or historical records. Low stalagmite growth rates could impede the acquisition of high-resolution isotope data with the classical micro-milling approach and isotope ratio mass spectrometry...

Interactions between protea plants and their animal mutualists and antagonists are structured more by energetic than morphological trait matching

Alexander Neu, Huw Cooksley, Karen Esler, Anton Pauw, Francois Roets, Frank Schurr & Matthias Schleuning
Traits mediate mutualistic and antagonistic interactions between plants and animals, and should thus be useful for predicting trophic species interactions. Studies to date have examined the importance of morphological trait matching for plant-animal interactions, but have rarely explored the extent to which these interactions are shaped by matching between energetic provisions of plants and energetic demands of animals. We tested whether energetic and/or morphological trait matching shapes interactions between Protea plant species and their interacting...

Profile of clinical characteristics and serologic markers of sporadic hepatitis E in a community cohort study

Zi-Min Tang, Gui-Ping Wen, Dong Ying, Si-Ling Wang, Chang Liu, Wei-Kun Tian, Ying-Bin Wang, Mu-Jin Fang, Yu-Lin Zhou, Yun-Sheng Ge, Ting Wu, Jun Zhang, Shou-Jie Huang, Zi-Zheng Zheng & Ning-Shao Xia
Hepatitis E virus (HEV) is a pathogen of global significance, but the value of HEV-related markers in the diagnosis of hepatitis E remains controversial. Previous studies on hepatitis E profiles have been mainly cross-sectional and conducted among inpatients in large hospitals, and hepatitis E cases have been primarily defined by limited partial markers. In this community-based study, 4,110 active hepatitis cases from a population of nearly 600,000 were followed over 48 months and serial serum...

Livestock management promotes bush encroachment in savanna systems by altering plant-herbivore feedback

Franziska Koch, Britta Tietjen, Katja Tielbörger & Korinna Allhoff
This repository contains all code to reproduce the analysis in Koch et al. 2022 "Livestock management promotes bush encroachment in savanna systems by altering plant-herbivore feedback". We use a set of coupled differential equations to describe competition between shrubs and grasses, as well as plant biomass consumption via grazing and browsing. Grazers were assumed to receive a certain level of care from farmers, so that grazer densities emerge dynamically from the combined effect of vegetation...

Elena Magenau, John Clifton-Brown, Danny Awty-Carroll, Chris Ashman, Andrea Ferrarini, Mislav Kontek, Enrico Martani, Kevin Roderick, Stefano Amaducci, Chris Davey, Vanja Jurišić, Jason Kam, Luisa Trindade, Iris Lewandowski & Andreas Kiesel
Miscanthus, a C4 perennial rhizomatous grass, is capable of growing in varied climates and soil types in Europe, including on marginal lands. It can produce high yields with low nutrient inputs when harvested after complete senescence. Senescence induction and rate depend on complex genetic, environmental, and management interactions. To explore these interactions, we analysed four miscanthus hybrids (two novel seed-based hybrids, GRC 3 (M. sinensis × sinensis) and GRC 14 (M. sacchariflorus × sinensis); GRC...

Floral visitation to alien plants is non-linearly related to their phylogenetic and floral similarity to native plants

Mialy Razanajatovo, Mialy Razanajatovo, Felana Rakoto Joseph, Princy Rajaonarivelo Andrianina & Mark Van Kleunen
Biological invasions are key to understanding ecological processes that determine the formation of novel interactions. Alien species can negatively impact floral visitation to native species, but native species may also facilitate early establishment of closely related alien species by providing a preadapted pollinator community. We tested whether floral visitation to alien species depended on phylogenetic relatedness and floral similarity to native species. In a field experiment, we simulated the early stages of an invasion by...
