Survival Tree01:19

Survival Tree

Survival trees are a non-parametric method used in survival analysis to model the relationship between a set of covariates and the time until an event of interest occurs, often referred to as the "time-to-event" or "survival time." This method is particularly useful when dealing with censored data, where the event has not occurred for some individuals by the end of the study period, or when the exact time of the event is unknown.

Threats to Biodiversity01:50

Threats to Biodiversity

There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...
Meristems and Plant Growth02:36

Meristems and Plant Growth

Plants grow throughout their lives; this is called indeterminate growth, and it distinguishes plants from most animals. Although certain parts of plants stop growing (e.g., leaves and flowers), others grow continuously—like roots and stems.
Phylogenetic Trees03:21

Phylogenetic Trees

Phylogenetic trees come in many forms. It matters in which sequence the organisms are arranged from the bottom to the top of the tree, but the branches can rotate at their nodes without altering the information. The lines connecting individual nodes can be straight, angled, or even curved.

Softwoods and Hardwoods01:28

Softwoods and Hardwoods

Softwoods and hardwoods, derived from different types of trees, are distinguished by their leaf structures and cellular compositions, each serving unique purposes in construction and manufacturing. Softwoods come from cone-bearing trees with needle-like leaves and are predominantly composed of longitudinal cells called tracheids and a smaller proportion of radial cells known as rays. Due to their cellular structure, softwoods are commonly used in construction for structural frames, sheathing,...

Area of Science:

  • * Evolutionary biology
  • * Phylogenetics
  • * Bioinformatics

Background:

  • * Understanding the evolutionary history and relationships of carnivores is essential for conservation and biological research.
  • * Previous phylogenetic studies have faced limitations in scope and methodology.
  • * The supertree approach offers a novel way to construct comprehensive phylogenies.

Purpose of the Study:

  • * To present an updated species-level phylogeny for carnivores using a supertree approach.
  • * To compare the supertree method with the supermatrix approach for phylogenetic inference.
  • * To discuss the strengths and limitations of different phylogenetic methodologies.

Main Methods:

  • * Construction of a supertree using existing molecular and morphological data.
  • * Comparative analysis of supertree and supermatrix methodologies.
  • * Discussion of phylogenetic principles and data integration techniques.

Main Results:

  • * The updated phylogeny provides significant new insights into carnivore evolution and relationships.
  • * The supertree approach, while valuable, has limitations and is subject to debate.
  • * Both supertree and supermatrix methods are deemed important for robust phylogenetic inference.

Conclusions:

  • * The supertree approach is a valuable tool for advancing carnivore evolutionary studies.
  • * Acknowledging the merits of both supertree and supermatrix methods enhances phylogenetic accuracy.
  • * Further research integrating diverse phylogenetic techniques is recommended.
