Protein Networks

Protein Networks

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Archival Research

Archival Research

Some researchers gain access to large amounts of data without interacting with a single research participant. Instead, they use existing records to answer various research questions. This type of research approach is known as archival research. Archival research relies on looking at past records or data sets to look for interesting patterns or relationships. For example, a researcher might access the academic records of all individuals who enrolled in college within the past ten years and...

Area of Science:

Marine Biology
Echinodermata Research
Biodiversity Databases

Background:

Asteroids (Echinodermata: Asteroidea) are key marine invertebrates.
Understanding their distribution is crucial for Antarctic and Sub-Antarctic ecosystems.
Existing data on Southern Ocean asteroids is fragmented.

Purpose of the Study:

To create a comprehensive, georeferenced database of asteroid occurrences in the Southern Ocean.
To consolidate historical and recent data for research and conservation efforts.
To include information on asteroid reproductive strategies.

Main Methods:

Data mining from diverse sources for georeferenced occurrence records south of 45°S latitude.
Inclusion of taxonomic, sampling source, and site information where available.
Quality control and validation of records from 1872 to 2016.

Main Results:

A dataset of 13,840 occurrences from 4,580 unique sampling events.
Compilation covers georeferenced data for Antarctic and Sub-Antarctic asteroids.
Reproductive strategy data (brooders vs. broadcasters) for 63 species is included.

Conclusions:

This database represents the most exhaustive occurrence record for Antarctic and Sub-Antarctic asteroids to date.
Facilitates future research on asteroid ecology, biogeography, and evolution in the Southern Ocean.
Provides a valuable resource for marine biodiversity assessments and conservation planning.
