Phylogenetic Trees03:21

Phylogenetic Trees

50.5K
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.

Diversity of Protists III

1.4K
Rhizaria are a diverse group of unicellular protists characterized by their threadlike cytoplasmic extensions known as pseudopodia. These structures aid in both locomotion and feeding, giving Rhizaria an amoeboid appearance. Their amoeboid morphology once led to taxonomic confusion, but molecular phylogenetics has clarified their evolutionary placement and emphasized their shared use of pseudopodia despite divergent lineages.This clade comprises diverse lineages such as Chlorarachniophyta,...

Gene Evolution - Fast or Slow?

8.3K
The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.
In contrast, regions which code...

When cells are placed in a hypotonic (low-salt) fluid, they can swell and burst. Meanwhile, cells in a hypertonic solution—with a higher salt concentration—can shrivel and die. How do fish cells avoid these gruesome fates in hypotonic freshwater or hypertonic seawater environments?

The Evidence for Evolution

48.9K
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

Area of Science:

  • Marine biology
  • Evolutionary biology
  • Ecology

Background:

  • Functional traits are key to coral reef fish evolution and diversification.
  • The link between functional traits and speciation, extinction, and local species pool filtering is not fully understood.

Purpose of the Study:

  • To review and analyze the evolution of functional traits (diet, body size, water column use, geographic range) in reef-associated fishes.
  • To uncover evolutionary patterns driving functional diversity using phylogenetic and trait data.

Main Methods:

  • Literature review of functional trait evolution in reef fishes.
  • Mapping functional traits onto published phylogenetic trees using new and existing data.
  • Reconstruction of evolutionary patterns for diet, feeding mode, body size, and range size.

Main Results:

  • Independent transitions to planktivory observed across reef fish families, suggesting ecological opportunity drives adaptation and speciation.
  • Extreme body sizes (large and small) evolved multiple times within mid-sized clades, primarily in the last 10 million years.
  • Disparate range sizes among sister species suggest vicariance; a relationship between labrid range size and lineage age was found when considering peripheral speciation.

Conclusions:

  • Trait evolution is shaped by trait-environment and trait-trait interactions.
  • Combining phylogenetic and functional approaches enhances understanding of species assembly in coral reef communities.
