An analysis of long-term data to assess the impact of climate and land use change on an apex avian predator from 1990 to 2028 The aim of this project is to study the impact of climate change and land use on: Life history traits Morphology (body size and proportion, plumage colouration) Population dynamics in the barn owl We will also analyze whether changes over time in all these traits is due to selection. We will also look at whether annual survival and/or breeding success is linked to variation in reproductive parameters, morphological traits and/or life history traits. This project is timely, as society demands a better understanding of the range of impacts of global change on biodiversity. This is particularly relevant for determining whether populations have had time to adapt to changing environmental conditions. The project proposed here to collect data in a wild population of barn owls in western Switzerland (400 nestboxes, up to 200 pairs per year) and to analyze data coll...

Two 3-year postdocs: (1) Theoretical evolutionary ecology, (2) Avian life history evolution We ( kokkonuts.org ) are interested in strengthening our research team that works on life history evolution in a broad sense, including the evolution of ageing, sexual reproduction, and evolutionary conflicts. We are therefore offering two postdoctoral positions. Both are offered for 3 years, ideally starting in January 2025 (with considerable flexibility). You will join a research group that will offer collaboration prospects within the group, with other researchers at JGU, as well as elsewhere via Prof. Kokko’s international network. Short- and long-term visitors, from workshops to sabbatical-length visits, bring in excellent prospects for collaboration and idea exchange between the postdoc and other theoreticians/empiricists as well. The precise topic of position (1) will be developed together with the postdoc (see application procedure below), while the postdoc of position (2) will take part...

(Mira Àreu, plantas y hongos, y cerca de las montañas :D) **Position: PhD Student in Bioflora Research Group** We are currently seeking an enthusiastic and motivated PhD student to join our Bioflora research group to work with us on co-evolution and adaptive speciation of pooid grasses and their fungal endophytes. We invite applications from ambitious candidates with relevant research experience and a passion to conduct research and innovation activities within the framework of a project funded by the Spanish Ministry of Science and Innovation (PID2022-140074NB-I00). The main objective of this research is to advance knowledge on the potential large extent of lateral gene transfer (LGT) in pooids and how this mechanism has contributed to generating evolutionary novelty. Additionally, we aim to investigate the potential co-evolution of grass-Epichloë holobionts and how this phenomenon has contributed to the success of adaptive speciation in temperate grasses. **Specific Objectives:*...

Oferta compartida por Nuria An evolutionary biologist is required for a Post-doc position within a grant ‘Historical morphometrics of the European bison skulls and its association with species inbreeding increase’. The project will be realized at the Mammal Research Institute, Polish Academy of Sciences, Białowieża, Poland. Summary and objectives of the project European bison is a species of unique demographic history. It has been through an extremely severe bottleneck in the 1920s. The whole contemporary population originates from a meager group of founders. Just two of them turned out to be predominant, and their share in the contemporary gene pool is above 80%. The effects are extremely low genetic variation (Wójcik et al., 2009; Tokarska et al., 2009; Tokarska et al., 2011) and highly increased inbreeding level, reaching 75% (Pertoldi et al., unpublished). Although increased inbreeding is regarded as an important factor affecting the viability of a population, resulting in lowere...
Oferta compartida por Nuria Postdoctoral Research Fellow in evolutionary genetics of venom We are searching for a Postdoctoral Research Fellow to run an evolutionary genetics experiment studying the molecular genetic underpinnings of evolvability using venom as a model. The fellowship will be for a period of three years and is affiliated with the Centre for Ecological and Evolutionary Synthesis at the University of Oslo Department of Biosciences. The person will be working in the Undheim group, where we are interested in questions in evolutionary biology that relate to how evolutionary innovations and novelties emerge and how they interact across levels of biological complexity. As relatively simple complex traits, venoms offer unique opportunities for studying molecular mechanisms underlying the ability of traits to respond to selection, i.e. their evolvability, which is currently a major focus of the group. The successful candidate will be working mainly on the microevolutionary...
Oferta compartida por Cristina Open PhD position in our lab! A complex systems approach to understanding the evolution of animal mating systems Understanding the drivers of diverse animal mating systems remains a key challenge in evolutionary biology. In particular, monogyny, where males mate with a single female during their lifetime, remains an evolutionary puzzle because male animals typically maximise reproductive success by mating with multiple females. Monogynous mating systems consist of multiple life history and behavioural traits, including dramatic adaptations such as the lifelong fusing of tiny male anglerfish to a female or the spontaneous death of a male during mating to form a whole-body mating plug in garden spiders. However, intricate correlations between system elements make it difficult to understand their roles in mating system evolution. Using Dolomedes fishing spiders as a model system, the PhD candidate will gain insight into the evolutionary pathways to mo...

Oferta compartida por Nuria A Postdoctoral Fellowship, funded for up to five years, is available within the Division of Evolutionary Ecology ( http://www.ee.iee.unibe.ch/index_eng.html ) led by Professor Catherine (Katie) Peichel at the University of Bern, Switzerland on a recently funded Swiss National Science Foundation project “FITNESS: Forward-In-Time Natural Experimental Study of Selection”. In this project, we have put over 10,000 stickleback fish into eight empty lakes in Alaska. Using whole-genome sequencing data from these founding fish and knowledge about the ecology of the lakes, we will determine whether the genotypes and the phenotypes of the fish change in a repeatable and predictable way over eight generations. The Postdoctoral Fellow will be responsible for leading the phenotypic axis of the project, which will involve yearly fieldwork in Alaska, phenotypic analyses of thousands of fish, and sophisticated multivariate analyses. This project is being carried out in coll...
