BackgroundAdaptation to local habitat conditions may lead to the natural divergence of populations in life-history traits such as body size, time of reproduction, mate signaling or dispersal capacity. Given enough time and strong enough selection pressures, populations may experience local genetic differentiation. The genetic basis of many life-history traits, and their evolution according to diff

In butterflies, male reproductive success is highly related to the quality and the size of the spermatophore transferred to the female. The spermatophore is a capsule produced by the male during copulation, which in many species contains sperm in addition to a nuptial gift, and which is digested by the female after copulation. The nuptial gift may contribute to egg production and offspring quality

Bicyclusbutterflies are key species for studies ofwing pattern development, phenotypic plasticity, speciationand the genetics of Lepidoptera. One of the key endosymbi-onts in butterflies, the alpha-ProteobacteriumWolbachiapipientis, is affecting many of these biological processes;however, Bicyclusbutterflies have not been investigated sys-tematically as hosts toWolbachia.Inthisstudy,wescreenforWo

The Lepidoptera is one of the most widespread and recognisable insect orders. Due to their remarkable diversity, economic and ecological importance, moths and butterflies have been studied extensively over the last 200 years. More recently, the relationship between Lepidoptera and their heritable microbial endosymbionts has received increasing attention. Heritable endosymbionts reside within the h

Protein stabilized emulsions made up of 40% soybean oil by weight and protein dispersions of 2.5% (w/w) protein content have been prepared in an ultrasonic device. The emulsifying apparatus was incorporated into a recirculating system, where power input and number of passes were varied. The food proteins studied were a soy bean protein isolate, a whey protein concentrate (WPC), and a sodium casein

All organisms are challenged by encounters with parasites, which strongly select for efficient escape strategies in the host. The threat is especially high for gregarious species entering immobile periods, such as diapause. Larvae of the Glanville fritillary butterfly, Melitaea cinxia, spend the winter in diapause in groups of conspecifics each sheltered in a silk-nest. Despite intensive monitorin

A new approach to prepare W/O/W-double emulsions is described. The inner W/O-phase is composed of a thermodynamically stable micellar solution of inverse type, an L2-phase. A protein, caseinate, is then used to stabilize the dispersion of this phase in water. Release from the inner to the outer water phase was followed by dialysis. Phase equilibria of the two ternary systems monolaurin-water-soybe

In the drop volume method the surface of the drop enlarges throughout the process of the interfacial tension decay. This surface expansion has been measured for drops of various sizes and shapes, where the interfacial tension depression was caused by different proteins such as lysozyme, β-lactoglobulin, bovine serum albumin, sodium caseinate, whey protein concentrate and soy protein isolate at dif

The density of roots is an important factor influencing the rate and magnitude of landslides. Due to the increased variability in climate, mainly rainfall, Eastern Uganda is severely struck by an increasing number of these mass movements, often with human casualties as one of the negative impacts. The aim of this study is to explore the possibility to estimate the depth and density of the root sys

The recent more or less complete return and recovery in Skåne, southern-most Sweden, of epiphytic bryophyes known to have suffered from atmospheric pollution in the mid 1900’s, e.g. Zygodon rupestris, Antitrichia curtipendula, Leucodon sciuroides, Orthotrichum lyellii, O. speciosum and O. stramineum, is here discussed and illustrated on maps. However, apart from these successful recoveries, at lea
