“…Yet, at a broader taxonomic scale, certain taxa of pollinating insects tend to visit particular plant taxa. This is exemplified by pollinator syndromes, in which plants are organized into functional groups with similar suites of morphological traits related to their interaction with pollinators, and it is thought that these functional groups also affect the selective pressures exerted on pollinators (Fenster, Armbruster, Wilson, Dudash, & Thomson, 2004; but see Ashworth et al, 2015;Ollerton et al, 2009).…”

Quantitative evolutionary patterns in bipartite networks: Vicariance, phylogenetic tracking or diffuse co‐evolution?

Many pairwise interactions in ecological communities are thought to be structured by co‐evolution, a process difficult to study on a community level. Traditional methods can reveal correlated phylogenies between interacting organisms, suggesting a co‐evolutionary association. However, several processes could lead to cophylogeny, including (1) vicariance, (2) phylogenetic tracking and (3) co‐evolution. We present a framework to investigate diffuse co‐evolution between groups of interacting taxa. Our methodology incorporates two complementary statistical methods to test for evolutionary signals. First, we test for correlated taxonomies between interacting species, and then we test for an association between the pattern of interactions and taxonomy of interacting species. We use these methods to clearly distinguish between three possible explanations of cophylogenies, when present. Our methodology is designed to explore diffuse evolutionary signals among many interacting taxa: it is robust to polytomies and generalization and can use taxonomic trees in place of phylogenies. Thus, we use taxonomic distances to identify groups of associated taxa, as opposed to specific co‐evolutionary relationships. In a case study, we find significant evidence for phylogenetic tracking, vicariance and asymmetry. Generally, our method can be applied whenever relevant taxonomy is well resolved and includes sufficient variation at multiple taxonomic ranks between two groups of interacting taxa. This adaptable method can incorporate many types of data on species traits or behaviours, such as phylogenetic relatedness, pollination efficacy, interaction strengths and visitation rates. The analysis we provide here may be of use to a broad range of ecologists interested in evaluating diffuse evolutionary patterns in groups of interacting species.

The interplay of polyploidisation, hybridization, and apomixis contributed to the exceptional diversity of Sorbus (Rosaceae), giving rise to a mosaic of genetic and morphological entities. The Sorbus austriaca species complex from the mountains of Central and South-eastern Europe represents an allopolyploid apomictic system of populations that originated following hybridisation between S. aria and S. aucuparia. However, the mode and frequency of such allopolyploidisations and the relationships among different, morphologically more or less similar populations that have often been described as different taxa remain largely unexplored. We used amplified fragment length polymorphism (AFLP) fingerprinting, plastid DNA sequencing, and analyses of nuclear microsatellites, along with multivariate morphometrics and ploidy data, to disentangle the relationships among populations within this intricate complex. Our results revealed a mosaic of genetic lineages—many of which have not been taxonomically recognised—that originated via multiple allopolyploidisations. The clonal structure within and among populations was then maintained via apomixis. Our results thus support previous findings that hybridisation, polyploidization, and apomixis are the main drivers of Sorbus diversification in Europe.

Our study highlights the utilization of a genetic database for wood-origin identification in Intsia palembanica, a valuable heavy hardwood from the tropical forests. This forensic tool is essential for strengthening the verification of legality in the wood supply chain from the forest to the end-users. An increasing number of rules and regulations are being put in place to promote sustainable practice in the timber trade, one of which involves ensuring that importers declare the correct species name and source of geographic origin of the timber. We aimed to determine the origin of the I. palembanica seed source used in the early establishment on the Forest Research Institute Malaysia (FRIM) campus. DNA samples of I. palembanica individuals from the FRIM campus were obtained and analyzed using four chloroplast (cp) DNA markers to characterize the haplotype variants for population identification. In addition, the DNA samples were also genotyped at 14 short tandem repeat (STR) loci for individual identification. Individual assignment to the possible geographic origin was done through an assignment test. On the basis of our recently developed I. palembanica genetic databases, the I. palembanica seed source for the early establishment was inferred to be originated from a mixture of several sources, with a large portion from the southern region (89%) and a relatively small portion from the northern region (11%) of Peninsular Malaysia. The I. palembanica seed source used for the early establishment on the century old FRIM campus was inferred to be originated from several forest reserves located not far from the planting sites. This study proves the applicability of the DNA method in supply-chain verification, where an unknown I. palembanica tree can be traced to its geographic origin using genetic databases.
