DOI: 10.1002/ece3.7489
Abstract: Abstract The presence of shell bands is common in gastropods. Both the marine snails Littorina fabalis and Lttorina saxatilis are polymorphic for this trait. Such polymorphism would be expected to be lost by the action… read more here.

DOI: 10.1002/ece3.9356
Abstract: Abstract Maintenance of variation in aposematic traits within and among populations is paradoxical because aposematic species are normally under positive frequency‐dependent predation (PFD), which is expected to erode variation. Aposematic traits can evolve in an… read more here.

DOI: 10.1002/ecy.3956
Abstract: Theoretical models suggest that infectious diseases could play a substantial role in determining the spatial extent of host species, but few studies have collected the empirical data required to test this hypothesis. Pathogens that sterilize… read more here.

DOI: 10.1002/mp.15344
Abstract: PURPOSE Scintillators and photoconductors used in energy integrating detectors (EIDs) have inherent variations in their imaging response to single detected x-rays due to variations in x-ray energy deposition and secondary quanta generation and transport, which… read more here.

DOI: 10.1007/s00707-015-1512-2
Abstract: AbstractPhase field simulations are conducted to investigate the frequency-dependent behavior of a ferroelectric single crystal with and without dislocation arrays. For the dislocation-free ferroelectric, both coercive field and remnant polarization increase with the increase in… read more here.
