Dietary flexibility promotes range expansion: the case of golden jackals in Eurasia

József Lanszki, Matthew W. Hayward, Nathan Ranc & Andrzej Zalewski
Aim: Exploring the drivers of the successful ongoing expansion of the golden jackal across Europe is essential to understand the species’ trophic ecology. We analysed which climatic and environmental factors affected the dietary composition of golden jackals and compared these drivers in the species’ historic and recently colonised distribution ranges. Location: Eurasia. Taxon: golden jackal (Canis aureus). Methods: Using 40 published data sets, we modelled the diet composition using 13 food categories based on the...

A simple method to describe the COVID-19 trajectory and dynamics in any country based on Johnson cumulative density function fitting

Adam Ćmiel & Bogdan Ćmiel
A simple method is utilised to study and compare COVID-19 infection dynamics between countries based on curve fitting to publicly shared data of confirmed COVID-19 infections. The method was tested using data from 80 countries from 6 continents. We found that Johnson cumulative density functions (CDFs) were extremely well fitted to the data (R2 > 0.99) and that Johnson CDFs were much better fitted to the tails of the data than either the commonly used...

GeldKunstNetz. Rechnungsbücher der Stettin-Danziger Kaufmannbankiersfamilie Loitz

Aleksandra Lipińska
Das interdisziplinäre und internationale Projekt untersuchte in den Jahren 2018-2019 die Rechnungsbücher (1566-1584) der Stettin (Szczecin)-Danziger (Gdańsk) Kaufmannbankiersfamilie Loitz, die sich im Staatsarchiv Danzig befinden. Das Ziel des Projekts war es, diese größte vorhandene Sammlung der frühneuzeitlichen Rechnungsbücher in Danzig (16 Archivalien, 969 S.) zu digitalisieren, online zu publizieren und wissenschaftlich aus drei methodischen Perspektiven auszuwerten. Erstens: als Quelle für die Geschichte des Finanzwesens und Handels im südlichen Ostseeraum. Zweitens: als Datenquelle für die Computer...

Data from: A Miopetaurista (Sciuridae, Rodentia) cranium from the middle Miocene of Bavaria (Germany) and brain evolution in flying squirrels

Isaac Casanovas-Vilar, Montserrat Grau-Camats, Ornella C. Bertrand, Jérôme Prieto, Sergi López-Torres & Mary Silcox
Flying squirrels (Sciurinae, Pteromyini) are the most successful group of gliding mammals. However, their fossil record mostly consists of isolated dental remains which provide very limited insights into their paleobiology and evolution. Only recently, the first skeleton of a fossil flying squirrel, belonging to the species Miopetaurista neogrivensis, has been described. It presents all the diagnostic gliding-related postcranial features of its extant relatives and shows that this group has undergone very little morphological change for...

Data from: Masting increases seedling recruitment near and far: predator satiation and improved dispersal in a fleshy-fruited tree

Barbara Seget, Michał Bogdziewicz, Jan Holeksa, Mateusz Ledwoń, Łukasz Piechnik, Fiona Milne-Rostkowska, Katarzyna Kondrat & Magdalena Żywiec
The animal dispersal hypothesis predicts that mast seeding can increase dispersal rate of seeds by dispersers and enhance reproductive success of plants. However, in contrast to pollination efficiency and predator satiation hypothesis, the animal dispersal hypothesis has received mixed support. Using 12-year data on fruit production and seedling recruitment of a fleshy-fruited tree rowan (Sorbus aucuparia, Rosaceae), we tested if an increase in the fruit production at the population level results in higher proportion of...

Plant cover and plant-pollinator interactions in Central European grasslands (Poland/Czech Republic)

Demetra Rakosy, Elena Motivans, Valentin Ştefan, Arkadiusz Nowak, Sebastian Świerszcz, Reinart Feldmann, Elisabeth Kühn, Costanza Geppert, Neeraja Venkataraman, Anna Sobieraj-Betlińska, Anita Grossmann, Wiktoria Rojek, Katarzyna Pochrząst, Magdalena Cielniak, Anika Kirstin Gathof, Kevin Baumann & Tiffany Marie Knight
Complex socio-economic, political and demographic factors have driven the increased conversion of Europe’s semi-natural grasslands to intensive pastures. This trend is particularly strong in some of the most biodiverse regions of the continent, such as Central and Eastern Europe. Intensive grazing is known to decrease species diversity and alter the composition of plant and insect communities. Comparatively little is known, however, about how intensive grazing influences plant functional traits related to pollination and the structure...

Data from: Scale-dependence of landscape heterogeneity effects on plant invasions

Dorota Kotowska, Tomas Pärt, Piotr Skórka, Alistair G. Auffret & Michał Żmihorski
Invasive alien species are amongst the most concerning threats to native biodiversity worldwide, and the level of landscape heterogeneity is considered to affect spatial patterns of their occurrence and spread. However, as previous studies on these associations report contrasting results, the role of landscape heterogeneity on its susceptibility to invasions remains poorly understood. Landscape heterogeneity is usually described by two measures: configuration and composition. Both measures may differently affect invasive species and these impacts may...

Timing and synchrony of birth in Eurasian lynx across Europe

Jenny Mattisson, John D.C. Linnell, Ole Anders, Elisa Belotti, Christine Breitenmoser-Würsten, Ludek Bufka, Christian Fuxjäger, Marco Heurich, Gjorge Ivanov, Włodzimierz Jędrzejewski, Radio Kont, Rafał Kowalczyk, Miha Krofel, Dime Melovski, Deniz Mengüllüoğlu, Tomma Lilli Middelhoff, Anja Molinari-Jobin, John Odden, Jānis Ozoliņš, Henryk Okarma, Jens Persson, Krzysztof Schmidt, Kristina Vogt, Fridolin Zimmermann & Henrik Andrén
The ecology and evolution of reproductive timing and synchrony has been a topic of great interest in evolutionary ecology for decades. Originally motivated by questions related to behavioural and reproductive adaptation to environmental conditions, the topic has acquired new relevance in the face of climate change. However, there has been relatively little research on reproductive phenology in mammalian carnivores. The Eurasian lynx (Lynx lynx) occurs across the Eurasian continent, covering three of the four main...

Cross-biome synthesis of source versus sink limits to tree growth

Antoine Cabon, Steven A. Kannenberg, Flurin Babst, Dennis Baldocchi, Soumaya Belmecheri, Nicolas Delpierre, Rossella Guerrieri, Justin Maxwell, Shawn McKenzie, Chritoforos Pappas, Adrian Rocha, Paul Szejner, Masahito Ueyama, Danielle Ulrich, Caroline Vincke, Jingshu Wei, David Woodruff, Altaf Arain, Rick Meinzer, David J. P. Moore, Steven L. Voelker, William R. L. Anderegg & Frederick C. Meinzer
Uncertainties surrounding tree carbon allocation to growth are a major limitation to projections of forest carbon sequestration and response to climate change. The prevalence and extent to which carbon assimilation (source) or cambial activity (sink) mediate wood production are fundamentally important and remain elusive. We quantified source-sink relations across biomes by combining eddy-covariance gross primary production with extensive on-site and regional tree ring observations. We found widespread temporal decoupling between carbon assimilation and tree growth,...

Breeding in the pandemic: Short-term lockdown restrictions in a European capital city did not alter the life-history traits of two urban adapters

Michela Corsini, Zuzanna Jagiello, Michał Walesiak, Michał Redlisiak, Ignacy Stadnicki, Ewa Mierzejewska & Marta Szulkin
Humans are transforming natural habitats into managed urban green areas and impervious surfaces with unprecedented peace. Yet, the effects of human presence per se on animal life-history traits are rarely tested. This is particularly true in cities, where human presence is often indissociable from urbanisation itself. We analysed four years of avian breeding data collected in a European capital city to test whether lockdown measures altered nestbox occupancy and life-history traits in terms of egg-laying...
