Convergent Evolution01:54

Convergent Evolution

29.1K
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.

Pinocytosis00:38

Pinocytosis

3.4K
Cells use energy-requiring bulk transport mechanisms to transfer large particles or large numbers of small particles into or out of the cell. The cells envelop the particles in spherical membranes called vesicles or vacuoles. Vesicles that transport material into the cell are built from the cell membrane. These vesicles encapsulate external molecules and transport them into the cell in a process called endocytosis.
Pinocytosis ("cellular drinking") is one of three main types of...

Osmoregulation in Fishes02:32

Osmoregulation in Fishes

50.5K
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?

Diversity of Protists II01:27

Diversity of Protists II

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...

Multi-species Conserved Sequences02:51

Multi-species Conserved Sequences

4.3K
Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale  studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved...

Poisson's Ratio01:23

Poisson's Ratio

546
Poisson's ratio is a material property that indicates their stress response. It explains the connection between the elongation or compression a material undergoes in the direction of an applied force and the contraction or expansion it experiences perpendicular to that force. When a slender bar is loaded axially, it stretches in the direction of the force and contracts laterally. Poisson's ratio is the negative ratio of this lateral contraction to the axial elongation. The negative sign...

Area of Science:

  • Marine Biology
  • Zoology
  • Evolutionary Biology

Background:

  • Alan Kohn's research established fish predation in two cone-snail species.
  • These species, Conus striatus and Conus catus, are now classified within the subgenus Pionoconus.
  • Pionoconus represents a distinct lineage among eight known piscivorous (fish-eating) cone snail clades.

Purpose of the Study:

  • To present an integrated, multidisciplinary review of Pionoconus biology.
  • To consolidate knowledge stemming from research initiated by Kohn's work.
  • To explore diverse facets of Pionoconus biology, from molecular to applied aspects.

Main Methods:

  • Comprehensive literature review of published research on Pionoconus.
  • Synthesis of data across various biological disciplines.
  • Analysis of studies covering molecular biology, phylogeny, biogeography, and behavior.

Main Results:

  • Detailed review of Pionoconus molecular biology and evolutionary relationships (phylogeny).
  • Exploration of their geographical distribution (biogeography) and life history traits.
  • Examination of specialized topics including prey-capture mechanisms, human envenomation, and biomedical potential.

Conclusions:

  • Pionoconus cone snails exhibit complex biology with significant ecological and biomedical relevance.
  • The subgenus represents a key group for understanding piscivory in Conus.
  • Alan Kohn's foundational research continues to influence and guide scientific inquiry into these fascinating marine snails.
