We integrate climatic niche models and dated phylogenies to characterize the evolution of climatic niches in Oenothera sections Anogra and Kleinia (Onagraceae), and from that we make inferences on diversification in relation to climate. The evolution of climatic tolerances in Anogra + Kleinia has been heterogeneous, across phylogenetic groups and across different dimensions of climate. All the ...

The large number of threatened species, both insects and plants, in the European agricultural landscape, has often been attributed to the abandonment of semi-natural grasslands. Species may also be threatened in the remaining managed grasslands due to a changed and intensified management, compared to the historical use. In this study, effects of grazing management and population characteristics...

There is discussion over whether pollen limitation exerts selection on floral traits to increase floral display or selects for traits that promote autonomous self-fertilization. Some studies have indicated that pollen limitation does not mediate selection on traits associated with either pollinator attraction or self-fertilization. Primula tibetica is an inconspicuous cross-fertilized plant tha...

This paper presents an approach to the Hamiltonian structure of isomonodromic systems of matrix ODE’s on a torus from their spectral curve. An isomonodromic analogue of the so called SU(2) Calogero-Gaudin system is used for a case study of this approach. A clue of this approach is a mapping from the Lax equation to a dynamical system of a finite number of points on the spectral curve. The coord...

Your Everyday, Average Academic The data described in this paper come from a unique cross section study collected by the author, using a postal questionnaire, of five Scottish Universities: Aberdeen, Dundee, Glasgow, Heriot-Watt and St. Andrews undertaken in 1995/6. It encompasses detailed information on the personal and working history of 900 academics. The paper aims to provide the reader wit...

We give a general prescription for deriving quark and lepton mass matrices with “texture” zeros in the framework of superstring inspired SO(10) models. The key to our approach is a new way to naturally implement the doublet–triplet splitting which enables us to obtain symmetric quark and lepton mass matrices which have different structures in the up and the down quark sectors. We illustrate our...

Jonathan A. Sherratt Centre for Theoretical Modelling in Medicine, Department of Ma thema tie, Heriot-Watt University, Edinburgh EH14 4AS, U.K. E-mail: jasbma.hw.ac.uk Abstract Predation is an established cause of cycling in prey species. Here, the ability of predation to explain periodic travelling waves in prey populations, which have recently been found in a number of spatiotemporal field st...
