Alban Pfeifer (UFZ, Germany)
Alban Pfeifer is conducting research on
the behaviour and population ecology of Maculinea nausithous
focusing on population size. Based on the
knowledge that females need to distribute eggs among the flower heads of
Sanguisorba officinalis as equally as possible to avoid competition
among caterpillars, with a maximum of three being able to survive per
flower head, the statistical distribution of eggs among flower heads is
being predicted. He is investigating egg-laying strategies with the
assistance of computer models. The aim of the research is to estimate
population sizes by counting eggs and calculating the probability of
overseeing a population, when no eggs are found in a flower head sample.
Zoe Randle (NERC, UK)
In the UK conservation management of the
Large Blue Butterfly, Maculinea arion, sites has led to an increase
in species abundance and diversity, in particular Myrmica sabuleti
(Maculinea arion’s host) and Viola species. Zoe Randle is
conducting research to find out what is happening on these sites and why
this is happening. It is well known that Myrmica ants create
microhabitats and enemy free space. Viola species have a seed with an
elaiosome; the elaiosome is an ant attractant that may aid seed dispersal.
Zoe is investigating the relationship between ants, plants and other
invertebrates to ascertain the ecological function of ants within their
ecosystem. Her PhD research is split into two parts: first the monitoring
over time of a restoration site from scratch to assess the impact of
management and re-colonisation rates of selected flora and fauna; second
to investigate why high biodiversity exists on Maculinea arion
sites. The following hypotheses are being tested:
i)High biodiversity exists because species share
similar niches or the same guild
ii)High biodiversity exists as a result of the
direct or indirect effect of ants on their community
Alexander Singer (UFZ, Germany)
Alex Singer aims to model and analyse
the complex population-dynamics of Maculinea-systems, focusing on the
influence of spatio-temporal structures. Taking Maculinea systems as a
starting point for studies on space-dependent predator-prey-dynamics, he
wants to understand, how space is percieved by different species in this
type of ecological system and how patterns of interaction between
different species process spatial and temporal heterogeniety. He hopes to
use his modelling approach to deduce rules for the evaluation and
management of habitat sites. Central questions:
i) Is space important to this
predator-prey-system?
ii)How does the system process spatial patterns?
iii) What is the influence of temporal
variations?
Piotr Skórka (UJAG, Poland)
Piotr Skórka is interested in the behaviour of animals
and its effect on population structure, in particular the influence of
landscape structure on mobility patterns, behaviour at species’ boundaries
and outside the natal patch. Furthermore, he is investigating the
methodology of animal counting, looking for quick and innovative methods
to estimate the population size of butterflies and ants.
