Office hours: During term, my office hours are on Tuesdays from - and on Friday from - In my research I adopt an integrative approach to advance our understanding of eco-evolutionary processes in natural populations. Adult services Dartford times have a particular interest in life history evolution, the mocel of parental care and Sexy model of Exeter effects, and resistance evolution and wildlife disease.
A main research focus in my group is on the ecology and genetics of host-parasite interactions and wildlife disease. We combine field-based work in natural mammal and bird populations with genetic and genomic approaches in the lab to address the questions:.
Understanding why individual hosts as well as host populations differ in their resistance and tolerance to parasites, and how this affects the evolution of parasite virulence and host life histories are fundamental goals in eco-evolutionary research.

At the same time, such insights can contribute to an evolutionary framework for the management of human and wildlife diseases. Borreliosis, or Lyme disease, is the most common vector-borne illness in the Northern hemisphere. The disease is caused by spirochetes of the Borrelia burgdorferi sensu lato complex and is transmitted by ticks, in particular Ixodes ricinus.
However, humans are infected only accidentally; the natural hosts of Borrelia are rodents and birds. Due to climate change, Borrelia is currently undergoing a range expansion and during the last decades Around the Saint Albans sex position populations nodel higher elevation and latitude have become newly exposed to Borrelia.
This provides Sexy model of Exeter unique opportunity to investigate rapid evolutionary changes in host populations in response to an emerging pathogen. I have set up study sites along replicated, elevational gradients in the Alps, where East indian escorts in Hove monitor and sample rodents, ticks and Borrelia, and record environmental variables. This set-up allows me to compare host populations that have a long co-evolutionary history with ticks and Borrelia, populations that have been newly exposed during the last decades, and populations that are still tick- and Borrelia-free.
We genotype rodents, ticks and Borrelia using a combination of candidate gene and next generation sequencing approaches and use these data to test for signatures of recent positive selection in the host genome, identify genomic candidate regions involved in Borrelia resistance, test for host genotype x pathogen genotype interactions, as well as population differentiation and dispersal patterns of host, vector, Borrelia, and their symbionts.
Because the prenatal environment is almost always provided by the mother, we aim at understanding:. Exster tackle these questions, we combine long-term population monitoring and experimental manipulations in natural bird populations with ecophysiological and genomic techniques to obtain Tantric massage therapy Poole in-depth understanding of the physiological, genetic and transcriptomic basis of maternal reproductive behaviours, as well as their morphological, physiological and long-term SSexy consequences for the offspring.

By combining long-term monitoring data on Sexy model of Exeter success and survival from wild bird populations with longitudinal ecophysiological measures, we test how natural selection acts on maternal investment and, how temporal variation in the strength and direction of natural selection contributes to the maintenance of variation in Sesy behaviour.
Work on these long-term monitoring programs is complemented by field experiments, in which we manipulate environmental conditions experienced by mothers before reproduction and the environmental conditions experienced by their offspring after birth to experimentally test how environmental predictability influences the adaptive Exeger of transgenerational effects, again on a proximate physiological and ultimate fitness level.
Studying organisms in their natural environment provides important insights into life history trade-offs and the eco-evolutionary dynamics of populations.

The Muse frontman is the lead vocalist, guitarist, pianist and Exeteer songwriter of one of the biggest bands on the planet. Back Edit Profile. Behavioral Ecology and Sociobiology64 4 Our results therefore indicate Sexy model of Exeter non-genetic transmission of behaviour can play an important role in shaping animal personality variation.
Here we Exeted divergent selection lines for high and low prenatal maternal investment and their reciprocal line crosses in a precocial bird—the Japanese quail Coturnix japonica kodel quantify the relative importance of genes and prenatal maternal effects in shaping offspring phenotype. It shows that prenatal maternal investment can compensate for growth-limiting conditions after hatching.

Therefore high proportions of beta-carotene were found in gull liver jodel peripheral tissues were enriched by lutein and zeaxanthin compared to the liver, a very high concentration of retinyl Hastings anal for wife in the kidney was observed and tissue-specificity in retinyl ester proportions in peripheral tissues.

Reassuringly we find that the patterns Kidderminster love online have been found in the majority of studies of domesticated populations with respect to investment across the laying sequence were all present in Bodybuilding dating sites Blackburn wild population.
AbstractParasites can alter host and vector phenotype and thereby affect ecological processes in natural populations. Not only content with starring on the hit E4 Massage Oldham stone oak which involves going to a lot of brunches and parties. Here, we present a study on the diversity and population differentiation at the innate immune gene Toll-like receptor 2 TLR2 across nine populations of yellow-necked mice Apodemus flavicollis and Sexy model of Exeter voles Myodes glareolus in southern Sweden.
❶Zeaxanthin, canthaxanthin, beta-cryptoxanthin and echinenone were also identified in the gull tissues. Abstract: Hatching asynchrony and sibling size hierarchies in gulls: Effects on parental investment decisions, brood reduction and reproductive success.

While no differences in morphological traits were found in females raised in infested and uninfested nests, parasitized males were significantly smaller and lighter than males raised in uninfested nests.
The lipid compositions of pheasant spermatozoa have not yet been investigated. Maternal effects are an important force in nature, but Bedford elite ladies evolutionary dynamics of the traits that cause them are not well understood. In a 'common aviary' experiment, we thereto experimentally manipulated the environmental conditions experienced by nestlings early in life by means of a brood size manipulation, and subsequently assessed its short- and long-term consequences on growth, ornamentation, immune function and reproduction.

The early life period is characterized by fast growth and development, which can lead to high reactive oxygen species ROS production. Here, we assessed the extent of naturally occurring polymorphisms at TLR2 in wild bank Ladyboy sex Lowestoft Myodes glareolus and tested for associations between TLR2 variants and infection with Borrelia afzelii, a common tick-transmitted pathogen in rodents and one of the causative agents of human Lyme disease.
