Data from: Introduced bees (Osmia cornifrons) collect pollen from both coevolved and novel host-plant species within their family-level phylogenetic preferences

Anthony Vaudo, David Biddinger, Wiebke Sickel, Alexander Keller & Margarita M Lopez-Uribe
Studying the pollen preferences of introduced bees allows us to investigate how species utilize host-plants when establishing in new environments. Osmia cornifrons is a solitary bee introduced into North America from East-Asia for pollination of crops in the Rosaceae. We investigated whether O. cornifrons 1) more frequently collected pollen from host-plant species they coevolved with from their geographic origin, or 2) prefer hosts-plant species of specific plant taxa independent of origin. To address this question,...

Functional groups of wild bees respond differently to faba bean (Vicia faba L.) cultivation at landscape scale

Nicole Beyer, Doreen Gabriel, Felix Kirsch, Katharina Schulz-Kesting, Jens Dauber & Catrin Westphal
1. Concerns about insect declines are growing and the provisioning of ecosystem services like pollination may be threatened. To safeguard biodiversity, greening measures were introduced within the reform of the EU’s Common Agricultural Policy. One measure commonly applied by farmers is the cultivation of nitrogen fixing crops. Although underlying studies are largely missing, this measure is criticized as providing no significant biodiversity benefit. 2. Using a landscape-scale approach, we selected 30 paired study landscapes (1km...

Data from: Behavioural and fitness effects of translocation to a novel environment: whole-lake experiments in two aquatic top predators

Christopher Monk, Bernard Chéret, Philipp Czapla, Daniel Hühn, Thomas Klefoth, Erik Eschbach, Robert Hagemann & Robert Arlinghaus
Translocation into a novel environment through common fisheries-management practices, such as fish stocking, provides opportunities to study behavioural and fitness impacts of translocations at realistic ecological scales. The process of stocking, as well as the unfamiliarity with novel ecological conditions and the interactions with resident fish may affect translocated individuals, leading to alterations of behaviours and causing fitness impacts. Our objectives were to investigate how aquatic top-predators behaviourally establish themselves and compete with resident individuals...

Species richness in North Atlantic fish: process concealed by pattern

Payne, Melita Peharda, Jakup Reinert … & Lilja Stefansdottir
Aim Previous analyses of marine fish species richness based on presence-absence data have shown changes with latitude and average species size, but little is known about the underlying processes. To elucidate these processes we use metabolic, neutral, and descriptive statistical models to analyse how richness responds to maximum species length, fish abundance, temperature, primary production, depth, latitude, and longitude, while accounting for differences in species catchability, sampling effort, and mesh size. Data Results from 53,382...

CO2-Zertifikate für die Festlegung atmosphärischen Kohlenstoffs in Böden: Methoden, Maßnahmen und Grenzen

Martin Wiesmeier, Stefanie Mayer, Carsten Paul, Katharina Helming, Axel Don, Uwe Franko, Markus Franko & Ingrid Kögel-Knabner
Agrarböden besitzen durch den Aufbau von organsicher Bodensubstanz (Humus), die zu etwa 58% aus Kohlenstoff (Corg) besteht, ein großes Potential zur Kohlenstoffbindung. Positive Anstrengungen im Humusmanagement könnten daher einen wesentlichen Beitrag für den Klimaschutz leisten. Für Landwirtinnen und Landwirte stellen so genannte CO2-Zertifikate für den Aufbau von Corg („Humuszertifikate“) einen zusätzlichen Anreiz dar, humusfördernde Bewirtschaftungsmaßnahmen umzusetzen. Diese CO2-Zertifikate werden von privatwirtschaftlichen Initiativen und Unternehmen im Bereich des freiwilligen CO2-Markts vergeben. Insbesondere im Bereich der Landwirtschaft...
