Here's How Trees Can Be Sources Of Pollution (And How They Can Stop)

Here's How Trees Can Be Sources Of Pollution (And How They Can Stop) | forests | Scoop.it
We know the drill. Cities are gray pollution farms and forests are verdant planetary saviors. We also know it’s more complicated than that. Here’s an interesting way a seemingly “green” forest can be a source of pollution.

Location matters in the lowland Amazon

Location matters in the lowland Amazon | forests | Scoop.it
"Our findings tell us that lowland Amazon forests are far more geographically sorted than we once thought," Asner explained. "It is not simply a swath of green that occurs with everything strewn randomly. Place does matter, even if it all appears to be flat and green monotony at first glance."

The Amazonian forest occupies more than five million square kilometers, stretching from the Atlantic coast to the foothills of the Andes. Thousands of tree and other plant species are found throughout this area, each synthesizing a complex portfolio of chemicals to accomplish a variety of functions from capturing sunlight to fighting off herbivores, to attracting pollinators, not to mention the chemical processes involved in adapting to climate change.

We need to protect Congo’s forests against shifting cultivation… or do we? | forests | Scoop.it
The Democratic Republic of Congo (DRC) is home to the second-largest single block of forest in the world, and its forests make up two-thirds of the Congo Basin forest area. Researchers have often concluded that slash-and-burn agriculture and biomass production are two of the most important causes of deforestation in the country....

Connecting the dots with a golden-winged warbler

Connecting the dots with a golden-winged warbler | forests | Scoop.it
For the first time, the same Golden-winged Warbler has been caught at both a migration hotspot and in his wintering grounds. Catching a warbler that someone else banded is "like a one in a million longshot," says the researcher who netted the bird in Nicaragua. "It's a needle in the haystack for sure, especially for this species." Connecting the dots between the breeding grounds, migration stop-overs and wintering grounds is important because Golden-winged warblers are sharply declining.

Study reveals how eastern US forests came to be | forests | Scoop.it
Spring visitors to Great Smoky Mountains or the Blue Ridge Parkway will see ridges and valleys covered in flowering mountain laurels, rhododendrons, tulip poplars, dogwoods, black locusts and silverbell trees. A new study of nearly all the trees and shrubs in the southern Appalachians suggests that roughly half of the species can trace their relatives to thousands of miles away in Asia. Most of the rest likely arose within North America, the researchers say.

Judit Urquijo's curator insight, April 22, 7:05 AM

Interesante artículo publicado por la web Salon que pone en entredicho el actual paradigma de la conservación natural y que sirve como extracto del libro "The new wild: why invasive species will be nature´s salvation", obra de Fred Pearce, periodista londinense especializado en medioambiente y ciencia. 

La noticia aborda cómo, en opinión del autor, las especies invasoras posibilitan la expansión de la biodiversidad y crean nuevas oportunidades para otras especies. Así, por ejemplo, cada vez más animales salvajes encuentran acomodo en los hábitats urbanos, áreas donde proliferan las especies exóticas e invasoras, adaptándose a las condiciones del medio. Aunque resulta interesante recordar la diferencia existente entre especies invasoras y especies alóctonas o no nativas, no debemos olvidar que al final, la naturaleza evoluciona en función de los recursos que disponen a su alcance. Así, por ejemplo, en mayo de 2014, la web Agencia SINC publicaba un artículo en el que se ponía de manifiesto el riesgo de desaparición que corría el rascón de manglar por la eliminación de un especie invasora de planta de la que se había hecho dependiente. 


Muchos naturalistas afirman que la conservación de los espacios naturales sin ningún tipo de introducción es necesaria para el mantenimiento de los servicios ecosistémicos que proporcionan estas áreas, pero voces como la de Peter Kareiva, jefe científico de Nature Conservancy, sostienen que muchas de estas áreas "son tan fieles a la naturaleza como Disneyland", puesto que el estado natural nunca es estable. Defienden que los servicios ecosistémicos pueden ser prestados igualmente por especies no nativas, especialmente en los ámbitos urbanos, donde la vegetación juega un papel esencial.


Así que la pregunta final se puede formular en los siguientes términos: especies invasoras ¿coexistencia y que sea la autorregulación natural la que decida, control para evitar grandes daños o lucha sin cuartel?
