Área de la Ciencia:
- Biología marina
- La oceanografía
- Ciencias del clima
Sus antecedentes:
- El fitoplancton marino es fundamental para los ecosistemas oceánicos.
- Los estados oceánicos son cada vez más extremos debido al cambio climático.
- Comprender las respuestas del fitoplancton es vital para predecir la salud del ecosistema marino.
Objetivo del estudio:
- Para investigar la resistencia del fitoplancton marino bajo condiciones oceánicas extremas.
- Identificar los mecanismos de adaptación del fitoplancton a los factores estresantes del medio ambiente.
- Evaluar las implicaciones de la resiliencia del fitoplancton para las redes alimentarias marinas.
Principales métodos:
- Utilizando un avanzado modelo oceanográfico.
- Analizando datos de población de fitoplancton a gran escala.
- El uso de pruebas de esfuerzo fisiológico en especies clave de fitoplancton.
Principales resultados:
- El fitoplancton marino exhibe una resistencia significativa a varios estados oceánicos extremos.

The Fossil Record
25.8K
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...

What is Evolutionary History?
40.4K
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 Evidence for Evolution
44.4K
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.

Diversity of Protists III
146
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,...

The Colonization of Land
35.8K
Changes in the environment of the early Earth drove the evolution of organisms. As prokaryotic organisms in the oceans began to photosynthesize, they produced oxygen. Eventually, oxygen saturated the oceans and entered the air, resulting in an increase in atmospheric oxygen concentration, known as the oxygen revolution approximately 2.3 billion years ago. Therefore, organisms that could use oxygen for cellular respiration had an advantage. More than 1.5 years ago, eukaryotic cells and...

The Carbon Cycle
40.2K
Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.
