Biodegradable plastics still damaging to fish      (via sciencedaily.com)     Original source 

Biodegradable plastics may not be the solution to plastic pollution many hoped for, with a new study showing they are still harmful to fish.

Whaling wiped out far more fin whales than previously thought      (via sciencedaily.com)     Original source 

Whaling in the 20th century destroyed 99% of the Eastern North Pacific fin whale breeding population. Because there is enough genetic diversity, current conservation measures should help the population rebound without becoming inbred. The future of fin whales in the Gulf of California depends on the recovery of the Eastern North Pacific population.

Orchid without bumblebee on island finds wasp, loses self      (via sciencedaily.com)     Original source 

Because the bumblebee that an orchid relies on for pollination does not exist on a remote island, the plant gets pollinated by an island wasp. Researchers found that this came at the cost of being hybridized with another orchid species adapted to being pollinated by the wasp. The finding showcases how plants in ecological relationships adapt to changing circumstances.

How to help save plants from extinction      (via sciencedaily.com)     Original source 

Now is the time to identify the conditions that cause plants to die. Doing so will allow us to better protect plants by choosing conservation targets more strategically, botanists argue.

Genomic analysis in snakes shows link between neutral, functional genetic diversity      (via sciencedaily.com)     Original source 

In the world of threatened and endangered species conservation, the genomic revolution has raised some complicated questions: How can scientists justify assessing species genetic diversity without consulting entire genomes now that they can be sequenced? But then again, how can scientists justify the time and expense of genome sequencing when age-old measures of neutral genetic diversity are much cheaper and easier to obtain? A new study suggests making a transition from 'old school' genetics to 'new school' genomics for species conservation purposes probably isn't necessary in all cases.

Flagship individual animals can boost conservation      (via sciencedaily.com)     Original source 

'Flagship' individual animals like Cecil the lion or Freya the walrus can boost conservation, new research suggests.

Bouldering in south-central Madagascar: A new 'rock-climbing' gecko species of the genus Paroedura      (via sciencedaily.com)     Original source 

A new Paroedura gecko species was reported at two small forest sites, Anja Reserve and Tsaranoro Valley forest, in the south-central plateau of Madagascar. Thanks to the recently collected samples, it was described and named after its preferred habitat, the boulders surrounded by the last remaining forests at these sites. Its conservation status was evaluated as Critically Endangered given its tiny distributional range.

Killer whales' diet more important than location for pollutant exposure      (via sciencedaily.com)     Original source 

Both elegant and fierce, killer whales are some of the oceans' top predators, but even they can be exposed to environmental pollution. Now, in the largest study to date on North Atlantic killer whales, researchers report the levels of legacy and emerging pollutants in 162 individuals' blubber. The animals' diet, rather than location, greatly impacted contaminant levels and potential health risks -- information that's helpful to conservation efforts.

Mummified feces reveals pre-Columbian cultures of the Caribbean consumed a diversity of plants      (via sciencedaily.com)     Original source 

DNA analysis of mummified feces reveals two pre-Columbian Caribbean cultures ate a wide variety of plants, like maize, sweet potato, and peanuts -- and tobacco and cotton traces were detected too, according to a new study.

Epiphytes, amazing plants like moss and bromeliads found in trees, face growing threats      (via sciencedaily.com)     Original source 

Epiphytes, plants such as orchids and mosses that grow in trees, draw nutrients from the air and create refuge for all sorts of other life forms. They are the foundation of forest canopy ecosystems, but they are facing threats from human and natural disturbances.

Death is only the beginning: Birds disperse eaten insects' eggs      (via sciencedaily.com)     Original source 

Relationship patterns among flightless stick insects suggest that birds disperse the eggs after eating gravid females. Lab experiments previously suggested the possibility, but a new genetic analysis of natural populations in Japan now supports the idea.

Wild pig populations in U.S. can be managed      (via sciencedaily.com)     Original source 

Recent conservation efforts have proven effective at controlling wild pig populations in the Southeastern United States, according to new research. Within 24 months of the start of control efforts in the study area located around the Savannah River Site in Aiken, South Carolina, researchers found a reduction of about 70% in relative abundance of pigs and a corresponding decline in environmental rooting damage of about 99%.
