3 cze 2022 · The R code to calculate the distance matrix and metrics is given in File S1, including the phylogenetic tree for the meadow community in Figure 1. File S2 includes code for creating a phylogenetic tree from a list of genus and species names of plants in any community.
9 gru 2021 · The nine priority research themes and their contribution to the conservation and management of pond ecosystems. Table 1. Key research themes, research questions, and future research identified in this paper to advance understanding of pond ecology and increase opportunities for pond conservation.
The Geographic Distance Matrix Generator is a platform-independent Java application that implements the same powerful suite of spherical functions as the Perpendicular Distance Calculator to compute all pair wise distances from a simple list of geographic coordinates.
10 lut 2020 · Here, from a macro-genetic perspective, we study the global distribution of genetic diversity in ray-finned fishes using data for 1611 freshwater and 3815 marine species.
6 gru 2013 · We investigated 84 fish ponds in the Dombes region, France, with five taxonomic groups: macrophytes, phytoplankton, macroinvertebrates, dragonflies, and amphibians. Species richness patterns were determined for α - (single pond), β - (between ponds), and γ - (regional pond network) levels.
31 paź 2023 · Genetic distance is used to explain the genetic divergence between species or between populations within a species and can indicate how closely related they are and whether they have a recent common ancestor or recent interbreeding has taken place.
Fitch–Margoliash method. The Fitch–Margoliash method uses a weighted least squares method for clustering based on genetic distance. [3] . Closely related sequences are given more weight in the tree construction process to correct for the increased inaccuracy in measuring distances between distantly related sequences.
