Migration

Migration

Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.

Osmoregulation in Fishes

Osmoregulation in Fishes

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?

What is Evolutionary History?

Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth and provides evidence for evolution. However, both fossil and living organisms offer evidence that outlines Earth’s evolutionary history.

The Fossil Record

The Fossil Record

The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most organisms never become fossils. Moreover, the fossil record only exhibits fossils that have been discovered. Nevertheless, sedimentary rock fossils of long-lived, abundant, hard-bodied organisms dominate the fossil record. These fossils offer valuable information, such as an organism's physical form, behavior, and age. Studying the fossil record helps...

Cell Migration

Cell Migration

Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.

Area of Science:

Marine Biology
Conservation Science
Ecology

Background:

Animal migrations are extensive, ubiquitous, and facing decline.
Effective conservation of migratory species requires identifying interconnected sites.
A gap exists between ecological research and policy-relevant information, hindering marine migrant conservation.

Purpose of the Study:

To synthesize existing research and identify key sites and migratory networks for marine megafauna.
To model the minimum extent of marine megafauna connectivity across global oceans.
To provide a tool for policymakers to understand and manage migratory species within their jurisdictions.

Main Methods:

Synthesized information from 1304 references.
Identified 1787 critical sites for migratory species.
Developed model migratory networks for 109 marine megafauna species.

Main Results:

Mapped the minimum extent of marine megafauna connectivity across global oceans.
Highlighted the importance of transboundary cooperation for conservation efforts.
Created a free online system for policymakers.

Conclusions:

Marine megafauna connectivity spans larger scales than current regional conservation structures.
Transboundary cooperation is crucial for the effective conservation of declining migratory species.
The online system facilitates efficient summarization of marine migrant use of jurisdictions.
