Osmoregulation in Fishes02:32

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?
Sustainable Development01:43

Sustainable Development

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

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...
Growth Models with Integration: Problem Solving01:27

Growth Models with Integration: Problem Solving

In population modeling, integration provides a systematic way to determine accumulated quantities from known rates of change. One such application arises in ecology, where the total weight of a fish population in a body of water is referred to as its biomass. When the rate of growth of this biomass is known as a function of time, calculus can be used to determine the total biomass at a future date.Growth Rate and Biomass FunctionLet the growth rate of the fish population be represented by a...
Freshwater Microbial Ecology01:24

Freshwater Microbial Ecology

Freshwater systems such as streams, rivers, and lakes exhibit distinct physical and biological characteristics that influence their microbial communities. These environments are broadly categorized into lotic systems—those with flowing waters like streams and most rivers—and lentic systems, which include still or slow-moving waters such as lakes, ponds, and marshes.In lentic systems, phytoplankton drive primary production, generating autochthonous organic carbon. In contrast, lotic systems...
Upstream Processing01:27

Upstream Processing

Upstream processing represents a critical phase in biomanufacturing, wherein biological systems such as microorganisms, mammalian cells, or insect cells are cultivated to produce therapeutic proteins, vaccines, enzymes, or other biologically derived products. This phase encompasses all steps from the selection and genetic manipulation of the production organism to the cultivation of cells in bioreactors under tightly controlled environmental conditions.Host Selection and Genetic OptimizationThe...

Resumen

La pesca marina mundial se enfrenta a la disminución de las capturas y la pérdida de biodiversidad debido a las tendencias actuales. Sin embargo, el examen de cuatro escenarios de desarrollo social indica que las tendencias negativas pueden revertirse y que los ecosistemas marinos pueden reconstruirse parcialmente.

Área de la Ciencia:

  • Biología marina Biología marina.
  • Ciencia de la pesca Ciencia de la pesca
  • La gestión de los ecosistemas.

Sus antecedentes:

  • Faltan análisis formales de las perspectivas a largo plazo de la pesca marina mundial.
  • La investigación pesquera actual prioriza el manejo local y específico de la especie.
  • Las tendencias actuales sugieren una expansión hacia aguas más profundas y una disminución de las capturas mundiales, potencialmente empeorada por los costos de combustible.

Objetivo del estudio:

  • Analizar las perspectivas a largo plazo de la pesca marina mundial.
  • Evaluar el impacto de las diferentes opciones de desarrollo social en la pesca y los ecosistemas.
  • Identificar vías potenciales para revertir las tendencias negativas y reconstruir los ecosistemas marinos.

Principales métodos:

  • Extrapolación de las tendencias actuales de la pesca.
  • Examen de cuatro escenarios distintos de desarrollo social.
  • Evaluación de los impactos en la biodiversidad y las capturas globales.

Principales resultados:

  • Sin intervención, las tendencias apuntan a una expansión más profunda del agua, pérdida de biodiversidad y reducción de las capturas globales.
  • Cuatro escenarios analizados ofrecen vías para revertir las tendencias negativas.
