Turtles unbothered by close drone monitoring, while birds and crocodiles flee

Bevan E, Whiting S, Tucker T, Guinea M, Raith A, Douglas R (2018) Measuring behavioral responses of sea turtles, saltwater crocodiles, and crested terns to drone disturbance to define ethical operating thresholds. PLoS ONE 13(3): e0194460. https://doi.org/10.1371/journal.pone.0194460 Unmanned aerial vehicles, more commonly known as drones, are quickly gaining popularity as cost effective tools for conservation […]

Important oyster-producing region of British Columbia swamped with microplastics

  If you grew up in the developed world, chances are you have an intimate relationship with plastic. Your lunch container, your childhood toys, your coffee press, that sweater you just bought, and the packaging it came in – they’re all made of low-cost petrochemical derivatives. And they’re swamping our oceans in a pollutant the […]

Old Bay of Fundy dykelands could sequester massive amounts of carbon if restored to saltmarsh

  Blue Carbon Blue carbon is a term scientists use to describe the organic material contained within all the living organisms and soil found in coastal ecosystems. Together, this organic matter, combined with the carbon contained in land-based systems, makes up the stored portion of the Earth’s carbon budget. Climate change scientists hope to protect […]

Agricultural Stewardship Could Prevent Invasive Species Takeover Downstream

  Phragmites australis, or Common Reed, is a marine grass likely introduced to North America from Eurasia in the late 1800s through the garden trade. It has since become one of the most aggressive invaders in history, replacing native grasses in wetlands and disrupting native ecosystem function. Wetlands are interesting study systems for invasive plants. […]

Just Put on the Market: Ideal for Coral Reef Development

Scientists Identify Best Spots for Reef Restoration Coral reefs have been front and center in the news lately, as rising temperatures, increased acidity, and nutrient pollution cause mass bleaching events and scientists lament losses they say mark the “death” of coral reefs around the world. Conservation superstars have even weighed in on the issue; Suzuki, […]

Facts not enough to stop whale watching vessels from disturbing killer whales

  Marine-based eco tourism is a fast-growing industry for many countries and vital part of coastal economies. In many places, it can also be a boon to the conservation of charismatic species that draw in the tourists. The Soundwatch Boater Education Program at the Whale Museum in Washington has been monitoring the behaviour of tourists […]

Invasive seagrass changes fish community in the US Virgin Islands

Seagrass meadows provide food and habitat for a variety of fish species. Juvenile fish are particularly dependent on the meadows, for the shelter they provide from predators. In the Caribbean, several native seagrasses might be found in the same shallow estuary or coastline, forming a patchwork of meadows that support a variety of different fish […]

Fantastic Invaders and Where to Find Them (Galapagos Edition)

Alien species are a commonly known and growing global concern. Increasingly transported to new locations and often following significant and increasingly widespread environmental degradation in their new homes, it seems more and more aliens are making the transition from visitor to invasive species. Some invaders, usually predators, can become particularly competitive and contribute directly or […]

Local disturbance and global warming unite to make seagrasses taste better to predators

Seagrasses form some of the most important habitats in the marine world. Under threat from global climate change as well as local disturbances, they’re also the subject of wide-spread investigation. Field and laboratory studies have shown that nutrient pollution, temperature changes, acidification, and other disturbances will negatively affect seagrass health, at the individual and community […]

Aliens in the kelp forests – community ecology and Miso soup

In the plant world, competition between species is almost always over space. Space dictates how much sunlight, nutrients, and potential mates you have access to. In community ecology, it’s thought that ecosystems only have so much space to offer different species, with some ecosystems containing more space than others. Most systems are also thought to be saturated so that, […]

Builders or Opportunistic Squatters? Invasive Species Drives Ecosystem Change on Georges Bank

See article here: https://link.springer.com/article/10.1007/s10530-017-1517-y Tunicates are underappreciated seafloor animals. Living sedentary lives and resembling some kind of marine slime, they don’t usually make it into headlines or flashy ocean documentaries. They are, however, important components of marine ecosystems (super cute ones too, like these bright blue ones), building bottom habitats and providing food for a […]

Size Matters: Big Eelgrass Beds Hold More Carbon

Oreska MPJ, McGlathery KJ, Porter JH (2017) Seagrass blue carbon spatial patterns at the meadow-scale. PLoS ONE 12(4): e0176630. https://doi.org/10.1371/journal.pone.0176630 Plants take in carbon dioxide as part of their normal functioning, to create carbon-based sugars for food. When they die, that carbon is decomposed in the soils or sediment and, eventually, released back to the […]

Spotlight on Constructed Wetlands

Wetlands are one of the world’s powerhouses for ecosystem services, filtering our water, controlling coastal erosion, and providing feeding and nursery habitat for a huge variety of wildlife. They are super productive, containing plant species that grow fast and therefore contribute a huge influx of organic material to the system when they die and start […]

The Entire Ocean in a Drop

Article: Stoeckle MY, Soboleva L, Charlop- Powers Z (2017) Aquatic environmental DNA detects seasonal fish abundance and habitat preference in an urban estuary. PLoS ONE 12(4): e0175186 Effectively managing fish populations requires accurate and timely monitoring data. Scientists and environmental managers need to know when (presence/absence data), where (location data), and how many fish (abundance […]

Public Perceptions of Aquaculture Show Lack of Ocean Literacy

Article: Froehlich HE, Gentry RR, Rust MB, Grimm D, Halpern BS (2017) Public Perceptions of Aquaculture: Evaluating Spatiotemporal Patterns of Sentiment around the World. PLoS ONE 12(1): e0169281. doi:10.1371/journal.pone.0169281 Aquaculture is one of the fastest growing industries in the world. A 2014 report by the UN-FAO estimated global freshwater and marine farming to constitute 44% of all […]

Life Finds a Way: Eelgrass Beds Respond in Surprising Ways to Extreme Warming Events

Article: Reynolds LK, DuBois K, Abbott JM, Williams SL, Stachowicz JJ (2016) Response of a Habitat-Forming Marine Plant to a Simulated Warming Event Is Delayed, Genotype Specific, and Varies with Phenology. PLoS ONE 11(6): e0154532. doi:10.1371/journal.pone.0154532 Climate change is poised to dramatically alter the make-up and functioning of Earths’ ecosystems, including those in the oceans. […]
