Oil Extraction Amazon Rainforest

Oil Extraction Amazon Rainforest | Rainforest EXPLORER:  News & Notes | Scoop.it

Oil Extraction Amazon Rainforest: "No one knows how long the Achuar people have lived deep within the Amazon rainforest on the border between Ecuador and Peru. They live there in harmony and in reverence of the rivers, trees, and animals that inhabit their spectacular surroundings. The rainforest is where the Achuar find their food, medicines, and raw materials to construct anything they need. It is their sacred place of worship."

Maintaining mimicry diversity: optimal warning colour patterns differ among microhabitats in Amazonian clearwing butterflies

Maintaining mimicry diversity: optimal warning colour patterns differ among microhabitats in Amazonian clearwing butterflies | Rainforest EXPLORER:  News & Notes | Scoop.it
Mimicry is one of the best-studied examples of adaptation, and recent studies have provided new insights into the role of mimicry in speciation and diversification. Classical Müllerian mimicry theory predicts convergence in warning signal among protected species, yet tropical butterflies are exuberantly diverse in warning colour patterns, even within communities. We tested the hypothesis that microhabitat partitioning in aposematic butterflies and insectivorous birds can lead to selection for different colour patterns in different microhabitats and thus help maintain mimicry diversity. We measured distribution across flight height and topography for 64 species of clearwing butterflies (Ithomiini) and their co-mimics, and 127 species of insectivorous birds, in an Amazon rainforest community. For the majority of bird species, estimated encounter rates were non-random for the two most abundant mimicry rings. Furthermore, most butterfly species in these two mimicry rings displayed the warning colour pattern predicted to be optimal for anti-predator defence in their preferred microhabitats. These conclusions were supported by a field trial using butterfly specimens, which showed significantly different predation rates on colour patterns in two microhabitats. We therefore provide the first direct evidence to support the hypothesis that different mimicry patterns can represent stable, community-level adaptations to differing biotic environments.

Was The Amazon Once An Ocean?

Was The Amazon Once An Ocean? | Rainforest EXPLORER:  News & Notes | Scoop.it
The Amazon rainforest is a treasure trove of biodiversity, containing 10% of the planet’s species in its 6.7 million square kilometers. How it got to be that way has been fiercely disputed for decades. Now, a new study suggests that a large section of the forest was twice flooded by the Caribbean Sea more than 10 million years ago, creating a short-lived inland sea that jump-started the evolution of new species. But the new evidence still hasn’t convinced scientists on the other side of the debate.

In Peru, canopy bridges keep rainforest animals connected over a gas pipeline

In Peru, canopy bridges keep rainforest animals connected over a gas pipeline | Rainforest EXPLORER:  News & Notes | Scoop.it
Hundreds of square miles of the Amazon are zoned for oil and gas exploration, with commercially viable reserves destined for national and international markets, including the US and the UK. But pipelines fragment the rainforest, dividing populations and disrupting the movements of species that spend their lives in the treetops. Now, a study using canopy camera trapping has shown that these impacts can be mitigated if natural canopy bridges are left in place when pipelines are constructed.

Amazonia's future will be jeopardized by dams

Amazonia's future will be jeopardized by dams | Rainforest EXPLORER:  News & Notes | Scoop.it
More than a hundred hydropower dams have already been built in the Amazon basin and numerous proposals for further dam constructions are under consideration. The accumulated negative environmental effects of existing dams and proposed dams, if constructed, will trigger massive hydrophysical and biotic disturbances that will affect the Amazon basin’s floodplains, estuary and sediment plume. We introduce a Dam Environmental Vulnerability Index to quantify the current and potential impacts of dams in the basin. The scale of foreseeable environmental degradation indicates the need for collective action among nations and states to avoid cumulative, far-reaching impacts. We suggest institutional innovations to assess and avoid the likely impoverishment of Amazon rivers.

Ants, not evil spirits, create poisonous devil’s gardens in the Amazon rainforest

Ants, not evil spirits, create poisonous devil’s gardens in the Amazon rainforest | Rainforest EXPLORER:  News & Notes | Scoop.it
"Devil's gardens are large stands of trees in the Amazonian rainforest that consist almost entirely of a single species, Duroia hirsuta, and, according to local legend, are cultivated by an evil forest spirit," write Frederickson and her colleagues in Nature. "Here we show that the ant, Myrmelachista schumanni, which nests in D. hirsuta stems, creates devil's gardens by poisoning all plants except its hosts with formic acid. By killing other plants, M. schumanni provides its colonies with abundant nest sites—a long-lasting benefit, as colonies can live for 800 years."
