Invasive species will save us: The new way we must think about the environment now

Invasive species will save us: The new way we must think about the environment now | forests | Scoop.it
Nature no longer congregates where we expect to find it -- so conservationists must radically rethink priorities

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?

The world's forests are fragmented and deteriorating, states a new paper published in Science Advances. After analyzing satellite imagery and compiling data from long-term fragmentation studies, the authors conclude that 70 percent of remaining forest land exists within 1 km of an edge, which negatively impacts their fauna, flora, and ecosystem services.

Who's funding palm oil?

Who's funding palm oil? | forests | Scoop.it
Palm oil may be the single most important crop that you never heard of. A vegetable fat that resembles reddish butter at room temperature, palm oil is derived from the fruit of the oil palm tree. Both nutritious and highly versatile, palm oil is now an important component of products ranging from biofuels and food to soaps and cosmetics. Estimates indicate that as much as 50 percent of the products used by the average Western consumer every day contain palm oil or its derivatives.

Spectacular Lost Hummingbird Rediscovered after 69 years amid Rampant Fires across the Sierra Nevada de Santa Marta in Colombia

Spectacular Lost Hummingbird Rediscovered after 69 years amid Rampant Fires across the Sierra Nevada de Santa Marta in Colombia | forests | Scoop.it
Described in 1880, the charismatic Blue-bearded Helmetcrest (Oxypogon cyanolaemus) was last seen in 1946; thereafter, it disappeared. Restricted to the world’s highest coastal mountain range, the Sierra Nevada de Santa Marta (rising to over 19,000 feet), the Helmetcrest was suspected to be facing severe threats as cattle ranching by indigenous people expanded across the sensitive high-elevation slopes of the mountain range. Each dry season, more of the fragile brush and forest is burned to make way for grasslands for cattle. The fragile montane forests of the Santa Marta mountains are unique as this isolated mountain range pre-dates the Andes of South America by over 100 million years

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.
