Cellular bicarbonate accumulation and vesicular proton transport promote calcification in the sea urchin larva

Marian Hu, Marian Hu, Inga Petersen, William Chang, Christine Blurton & Meike Stumpp
The sea urchin embryo develops a calcitic endoskeleton through intracellular formation of amorphous calcium carbonate (ACC). Intracellular precipitation of ACC, requires HCO3-/CO32- concentrating as well as proton export mechanisms to promote calcification. These processes are of fundamental importance in biological mineralization, but remain largely unexplored. Here we demonstrate that the calcifying primary mesenchyme cells (PMCs) utilize Na+/H+- exchange (NHE) mechanisms to control cellular pH homeostasis during maintenance of the skeleton. During skeleton re-calcification, pHi of...

Toolbox for: Teaching lab for large cohorts of undergraduates: private and social information in fish

Jost Borcherding, Mike M Webster & Katja Heubel
A challenge in the Bachelor's studies in Biology, is to strive for a balance between reducing the teaching of practical scientific experiments to what is feasible in a short time, and teaching "real" science in undergraduate labs for high numbers of participants. We describe a lab in behavioural biology, with the primary focus on the student learning. However, also the underlying scientific question and the results of the experiment, namely the behaviour of the three-spined...

Data from: Native distribution characteristics rather than functional traits explain preadaptation of invasive species to high-UV-B environments

Maria Hock, Rainer Hofmann, Franz Essl, Petr Pyšek, Helge Bruelheide & Alexandra Erfmeier
Aim: Alien species successfully colonize new ranges if they encounter favourable environmental conditions there and possess traits that match new challenges. Climate matching approaches comparing native and exotic ranges mostly consider temperature and precipitation niches of alien species, but have largely ignored UV-B radiation. UV-B fundamentally differs between hemispheres, with much higher levels at southern than at northern latitudes. Consequently, UV-B might act at the global scale and present a so far neglected filter that...

Data from: The glue produced by Drosophila melanogaster for pupa adhesion is universal

Virginie Courtier-Orgogozo, Flora Borne, Alexander Kovalev & Stanislav Gorb
Insects produce a variety of adhesives for diverse functions such as locomotion, mating, egg or pupal anchorage to substrates. Although they are important for the biology of organisms and potentially represent a great resource for developing new materials, insect adhesives have been little studied so far. Here, we examined the adhesive properties of the larval glue of D. melanogaster. This glue is made of glycosylated proteins and allows the animal to adhere to a substrate...

ADCP current measurements (75 kHz) during Maria S. Merian cruise MSM88/1

Colin W Devey & Robert Kopte
Upper-ocean velocities along the cruise track of Maria S. Merian cruise MSM88/1 were continuously collected by a vessel-mounted Teledyne RD Instruments 75 kHz Ocean Surveyor ADCP. The transducer was located at 6 m below the water line. The instrument was operated in narrowband mode with 8 m bins and a blanking distance of 8 m, while 100 bins were recorded using a pulse of 1.45 seconds. The ship's velocity was calculated from position fixes obtained...

Biogeographic differences in plant-soil biota relationships contribute to the invasion exotic range expansion of Verbascum thapsus

Julia Dieskau, Helge Bruelheide, Alexandra Erfmeier & Jessica Gutknecht
Exotic plant species can evolve adaptations to environmental conditions in the exotic range. Furthermore, soil biota can foster exotic spread in the absence of negative soil pathogen-plant interactions or because of increased positive soil biota-plant feedbacks in the exotic range. Little is known, however, about the evolutionary dimension of plant-soil biota interactions when comparing native and introduced ranges. To assess the role of soil microbes for rapid evolution in plant invasion, we subjected Verbascum thapsus,...

Drought sensitivity of Empetrum nigrum shrub growth at the species’ southern lowland distribution range margin

Stef Weijers, Nils Hein, Julia Merkelbach & Katharina Zech
The ongoing warming of the Earth’s atmosphere is projected to cause a northward shift of species’ distributions, as they track their climatic optimum. In the rapidly warming Arctic, this has already led to an increase of shrubs in tundra ecosystems. While this northern expansion of woody biomass has been studied relatively extensively over the last decade, little research has been devoted to shrub growth responses at the southern margins of Northern Hemisphere shrubs. Here, we...
