What is Evolutionary History?

40.6K
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.

Sustainable Development

13.6K
As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

The Fossil Record02:56

The Fossil Record

25.9K
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...

Primary Production01:06

Primary Production

24.1K
The total amount of energy acquired by primary producers in an ecosystem is called gross primary production (GPP). However, of this energy, producers use some for metabolic processes, and some is lost as heat, decreasing the amount of energy available to the next trophic level. The remaining usable amount of energy is called the net primary productivity (NPP). In terrestrial ecosystems, NPP is driven by climate, while light penetration and nutrient availability drive NPP in aquatic ecosystems.

The Colonization of Land02:22

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...

Diversity of Protists III01:27

Diversity of Protists III

153
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,...

Área de la Ciencia:

  • Biología marina
  • Ciencias del clima
  • Ecología

Sus antecedentes:

  • Los ecosistemas oceánicos enfrentan amenazas sin precedentes por el cambio climático antropogénico.
  • El aumento de las temperaturas globales y los cambios ambientales asociados están alterando los hábitats marinos.
  • Comprender las consecuencias a largo plazo del cambio climático es crucial para los esfuerzos de conservación.

Objetivo del estudio:

  • Modelar el impacto potencial del cambio climático no frenado en la biodiversidad marina.
  • Para predecir la probabilidad y la escala de un evento de extinción masiva en entornos oceánicos.
  • Proporcionar pruebas científicas que apoyen la necesidad de estrategias inmediatas de mitigación del clima.

Principales métodos:

  • Desarrollo y aplicación de un modelo ecológico predictivo.
  • Integración de los datos de proyección climática con la distribución y la vulnerabilidad de las especies marinas.
  • Análisis de los umbrales de extinción bajo varios escenarios de calentamiento.

Principales resultados:

  • El modelo predice una alta probabilidad de una extinción masiva en los océanos si las tendencias actuales de cambio climático continúan sin disminuir.
  • Se identifican regiones marinas específicas y especies clave como particularmente vulnerables.
  • La severidad del evento de extinción predicho aumenta con el aumento de las temperaturas globales.

Conclusiones:

  • El cambio climático representa una amenaza grave e inminente para la vida marina, que podría conducir a una extinción masiva.
  • Las reducciones urgentes y significativas de las emisiones de gases de efecto invernadero son necesarias para evitar el colapso catastrófico del ecosistema oceánico.
  • Este estudio subraya la necesidad crítica de una cooperación mundial en materia de política climática para salvaguardar la biodiversidad marina.
