The geotectonic evolution of the Aegean islands has had a major contribution in shaping the biogeographic patterns of all recent taxa of these areas (see brief review in and references therein). The islands have been formed under the influence of three major forces: tectonism, volcanism, and eustatism. Throughout the Aegean islands history, repeat...
The habitats on Aegean islands have been extensively affected by modern humans, who are continuously present on almost all of them for more than 10,000 years . There is even evidence for Palaeolithic (ca. 130,000 years ago) human settlement, e.g. on Crete , but permanent occurrence probably started around the end of the last glacial period. Of cour...
As we have seen, the palaeogeography and palaeoecology of the Aegean has been very dynamic, with most of modern islands having a long history of repeated merging into larger islands and subsequent fragmentation, of connection and disconnection to neighboring mainland, and of changes in their ecological and topographic features. In consequence, rese...
Patterns of species richness
What determines the number of species present in a defined region? This is a central question in ecology and a relation between the area of the studied region and the species richness observed therein has been one of the first described patterns in biogeography. Elaborations on the species–area relationships (SARs) have occupied a large bulk of the twentieth century ecological literature, and continue to produce interesting theoretical advancements also in the twenty-first century [26–30]. On...
Community assembly
Insular communities have also played an important role in the development of community-level theories that relate to what has been generally addressed as ‘assembly rules’, such as those related with community nestedness and species co-occurrences, as well as patterns of alpha- and beta-diversity. Nestedness related research on Aegean islands has contributed to this discussion, mainly through the analysis of a few taxa for which detailed information on both local and ‘regional’ communities has...
Evolutionary diversification on island systems has been central in the development of evolutionary theory, since the multiple isolation of an initially common genetic pool, i.e., of the first immigrants, can lead to quick allopatric speciation. Adaptive radiation on archipelagos has been shown in several taxa and is a fairly well understood process...
Studies of animal or plant communities and assemblages on islands may have provided significant insights into the various aspects of island biogeography theory, but what about the ecology of insular systems? What have we learned on the way species and communities interact within each island and with the abiotic components of the environment? This l...

When most of us think of an island, we think of a lush biodiverse paradise, but what about an entire cluster of these islands offering near-endless adventure and natural life to explore? Archipelago islands are simply a tight cluster, group, or chain of islands that can be found in various locations around the world.
Jun 5, 2012 · Geographically, islands are defined as areas of land surrounded by water. This results in a degree of biological isolation – it is difficult for terrestrial organisms to colonise small islands which lie far from a large land mass. Other habitats of similar types may also be isolated from each other.
Feb 19, 2020 · Analysis of a unique global data set reveals how the species diversity of birds is affected by the properties of archipelagos and offers a way to test an influential theory.
