Key concepts and a world-wide look at plant recruitment networks.

Plant-plant interactions are major determinants of the dynamics of terrestrial ecosystems. There is a long tradition in the study of these interactions, their mechanisms and their consequences using experimental, observational and theoretical approaches. Empirical studies overwhelmingly focus at the level of species pairs or small sets of species.

Cerebral blood flow and arterial responses in migraine: history and future perspectives.

Introduction: It is largely accepted that migraine with aura (MA) is caused by cortical spreading depression (CSD) and that migraine without aura (MO) is not. This is mostly based on old studies of regional cerebral blood flow (rCBF) and studies of vascular responses. These studies are partly forgotten today and may, therefore, be worthwhile reviewing.

Field-testing the explicit diagnostic criteria for transient ischemic attack: a diagnostic accuracy study.

Background And Aim: Explicit diagnostic criteria for transient ischemic attack (TIA) (EDCT) have been recently proposed based on the assumption, that a migraine aura-like symptom is not typical for a TIA. However, migraine-like symptoms have been unexpectedly frequent in patients with confirmed ischemic stroke. This cross-sectional study aimed to field-test the EDCT to distinguish transient neurological symptoms caused by cerebral infarction from those caused by migraine aura.

Methodology of drug trials in migraine: History and suggestions for the future.

There is a multitude of scientific papers and guideline papers on the methodology of drug trials in migraine. Here, we try to condense this into a single paper and to make proposals for future consideration. Literature known by the authors and from reference lists of relevant publications was used for the history.

Climb forest, climb: diverse disperser communities are key to assist plants tracking climate change on altitudinal gradients.

Climate change is forcing species to shift their distribution ranges. Animal seed dispersers might be particularly important in assisting plants tracking suitable climates to higher elevations. However, this role is still poorly understood due to a lack of comprehensive multi-guild datasets along elevational gradients.
