Resumen

Las plantas forestales europeas se están desplazando hacia el oeste, no hacia el norte. La deposición de nitrógeno, no el cambio climático, impulsa estos sorprendentes cambios en la biodiversidad, influenciados por la recuperación de la lluvia ácida.

Área de la Ciencia:

Ecología
Ciencias del medio ambiente
Botánica

Sus antecedentes:

A menudo se asume que la distribución de las especies cambia hacia los polos debido al cambio climático.
Los factores ambientales más allá del clima, como la deposición atmosférica y la dinámica forestal, pueden influir en los rangos geográficos de las especies.
Comprender estos factores es crucial para predecir los cambios en la biodiversidad.

Objetivo del estudio:

Cuantificar los cambios de varias décadas en la distribución de las plantas forestales europeas.
Identificar los factores clave de estos cambios de distribución observados, incluidos el cambio climático, la deposición de nitrógeno y azufre y la dinámica del dosel forestal.
Desafiar la suposición de que el cambio climático es el único impulsor de los cambios de rango de las especies.

Principales métodos:

Análisis de los datos de distribución multidecadal de las plantas forestales europeas.
Enlace estadístico de los cambios de distribución observados con las variables ambientales: cambio climático, deposición atmosférica (N, S) y dinámica del dosel forestal.
Análisis comparativo de la influencia de diferentes factores en los cambios observados.

Principales resultados:

Los desplazamientos hacia el oeste fueron 2,6 veces más frecuentes que los desplazamientos hacia el norte en las plantas forestales europeas.
Los eventos de colonización mediados por nitrógeno fueron identificados como el principal impulsor de los movimientos hacia el oeste.
Estos efectos del nitrógeno pueden verse reforzados por la recuperación de la deposición acidificante histórica.

Conclusiones:

La redistribución de la biodiversidad es compleja, impulsada por múltiples cambios ambientales que interactúan.
El cambio climático no es el único factor; la deposición de nitrógeno juega un papel importante en la configuración de los rangos de las especies.
La investigación futura debería considerar la interacción de varios factores, no solo el clima, para predecir las respuestas de las especies al cambio ambiental.

The Roles of Bacteria and Fungi in Plant Nutrition

The Roles of Bacteria and Fungi in Plant Nutrition

Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

Threats to Biodiversity

Threats to Biodiversity

There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

The Nitrogen Cycle

The Nitrogen Cycle

Nitrogen atoms, present in all proteins and DNA, are recycled between abiotic and biotic components of the ecosystem. However, the primary form of nitrogen on Earth is nitrogen gas, which cannot be used by most animals and plants. Thus, nitrogen gas must first be converted into a usable form by nitrogen-fixing bacteria before it can be cycled through other living organisms. The use of nitrogen-containing fertilizers and animal waste products in human agriculture has greatly influenced the...

Overview of Nitrogen Metabolism

Overview of Nitrogen Metabolism

Nitrogen is a very important element for life because it is a major constituent of proteins and nucleic acids. It is a macronutrient, and in nature, it is recycled from organic compounds and stored in the form of ammonia, ammonium ions, nitrate, nitrite, or nitrogen gas by many metabolic processes. Many of these metabolic processes are carried out only by prokaryotes.
The largest pool of nitrogen available in the terrestrial ecosystem is gaseous nitrogen (N2) from the air, but this...

Global Climate Change

Global Climate Change

Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Key Elements for Plant Nutrition

Key Elements for Plant Nutrition

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...
