takesimensis (2) clear genetic differentiation between P. The results of phylogenetic reconstruction and population genetic structure analyses based on single nucleotide polymorphisms detected by multiplexed inter-simple sequence repeat genotyping by sequencing (MIG-seq) and complementary cpDNA haplotypes provided evidence for (1) the monophyly of P. takesimensis using multiple molecular markers. sargentii from Ulleung Island and its adjacent areas, the current study revealed the origin and evolution of P. Based on extensive sampling of wild flowering cherries, including P. However, the overall genetic complexity and resultant non-monophyly of closely related flowering cherries have hindered the determination of their phylogenetic relationships as well as the establishment of concrete continental progenitors and insular derivative relationships. sargentii Rehder distributed in adjacent continental areas and islands has been suggested as a purported continental progenitor. As the only flowering cherry occurring on Ulleung Island in the East Sea (concurrently known as Sea of Japan), Prunus takesimensis Nakai has been presumed to be derived through anagenetic speciation on the island. However, continued efforts should be made towards compiling new information on their biodiversity, to pursue various fruitful research avenues and develop appropriate conservation management tools.read more read lessĪbstract: Of the two major speciation modes of endemic plants on oceanic islands, cladogenesis and anagenesis, the latter has been recently emphasized as an effective mechanism for increasing plant diversity in isolated, ecologically homogeneous insular settings.
A large amount of data is now available for several groups of organisms on and around many of these islands. The Macaronesian Islands are a well-suited field of study for island ecology and evolution research, mostly due to its special geological layout with 40 islands grouped within five archipelagos differing in geological age, climate and isolation.
#Adaptive radiation island drivers
Several innovative conservation and management actions are in place to protect its biodiversity from these and other drivers of global change. However, in addition to exceptionally high richness of endemic species, Macaronesia is also home to a growing number of threatened species, along with invasive alien plants and animals. This group of archipelagos (Azores, Madeira, Selvagens, Canary Islands, and Cabo Verde) has been crucial to learn about the particularities of macroecological patterns and interaction networks on islands, providing evidence for the development of the General Dynamic Model of oceanic island biogeography and subsequent updates.
Macaronesia also seems to be an important source region for back-colonization of continental fringe regions on both sides of the Atlantic. Some of these discoveries indicate that the Macaronesian flora and fauna is composed of rather young lineages, not Tertiary relicts, predominantly of European origin. We review the scientific developments achieved in this region, and outline promising research avenues enhancing conservation. Abstract: Research in Macaronesia has led to substantial advances in ecology, evolution and conservation biology.
