The university through its Trout Lake Station in Boulder Junction Wisconsin has played a pivotal role in the Global Lake Ecological Observatory Network (GLEON) an international network that has placed observation buoys at more than 100 lakes.
The 24/7 nature of data collection is essential says Tim Kratz director of Trout Lake and a GLEON founder.
Big algae bloom in Lake erie, very dry 2015 forecastscientists delivered a mostly negative forecast for how climate change will affect Ohioans during the next year or so and well beyond.
if the 2014 algae bloom could approach the size of the one in 2011--the largest in Erie's history As these blooms move into the Central Basin east of Sandusky they tend to die
Lake erie often produces more fish for human consumption than all the other Great lakes combined he explained.
An algae bloom not only hinders swimming and boating--it also affects the fishery So tourism and fisheries are both likely to be impacted.
But the consequences will be strongest for Toledo and Maumee Bay where the bloom is likely to be most severe.

#Crabs killing Northeast saltmarshes, study confirmsa marathon summer of field work by Mark Bertness professor of ecology and evolutionary biology and a squadron of students may finally help settle the heated debate about
The winner by far was runaway herbivory of cordgrass by the Sesarma crab. In the other study published in the journal Ecology Letters they directly tested that hypothesis with experiments on Cape cod.
The results were that wherever they protected Sesarma from the pressure of predators the crabs ruthlessly mowed the grasses down.
because overfishing has reduced the predators that would naturally keep the crabs in check. Long-held beliefs that physical forces rather than disrupted food webs are killing the marshes just aren't true Bertness said.
A summer of salt crabs and mudbertness'team included lab manager Caitlin Brisson seniors Matt Bevil and Sinead Crotty and junior Elena Suglia.
and then protected it from all herbivores including the crabs. To assess whether any site had too much nitrogen they took leaves of the grasses at each site back to the lab ground them up
and then stopping every two meters to measure signs of crab damage on 100 cordgrass stalks.
In August they tethered crabs to make them more vulnerable to predators and measured how much predation there was.
Substrate hardness influences crab herbivory by limiting crab burrowing in hard and soft substrates leading to a peak in herbivory in medium hardness substrates where burrows can be constructed easily
but they also implemented a direct test of the Sesarma herbivory hypothesis. They erected cages on some plots that could protect the crabs from predators.
Warming has resulted already in plankton fish and invertebrate communities shifting northwards. In northern marine areas the diversity and biomass of fish populations have increased.
Water warming has altered also the distribution of large species of fish found in the open sea.
As marine and coastal ecosystems change their diversity and the products and services derived from them will weaken.
Those who depend on coastal areas for their livelihoods such as fishing communities in the tropics and arctic areas will suffer.

#Ancient clam gardens nurture food securitya three-year study of ancient clam gardens in the Pacific Northwest has led researchers including three from Simon Fraser University to make a discovery that could benefit
The researchers discovered that ancient clam gardens made by Aboriginal people produced quadruple the number of butter clams and twice the number of littleneck clams as unmodified clam beaches.
This is the first study to provide empirical evidence of ancient clam gardens'superior productivity. In the past as indigenous coastal communities from Alaska to Washington state grew in numbers people needed to devise sustainable ways of feeding themselves.
One of the ways they did this was by cultivating clams in human-made rock-walled beach terraces known as clam gardens.
When the researchers transplanted more than 800 baby clams into six ancient clam gardens and five non-walled natural beaches to compare their growth rates they made a groundbreaking discovery.
The clams in the ancient gardens grew almost twice as fast and were more likely to survive than baby clams transplanted into unmodified beaches in the same area.
We discovered that flattening the slope of ancient beach clam gardens expanded the real-estate for clams at the intertidal height at
which they grow and survive best explains Salomon. The School of Resource and Environmental Management assistant professor adds:
Traditional knowledge by coastal First Nations members further revealed that their ancestors boosted these gardens'productivity by adding ground clam shell and pebbles to them.
The researchers began their clam garden investigations in 2008. From 2009 to 2011 they focused their efforts on Quadra Island due to the sheer number of clam gardens available to survey
and use as experimental replicates. They surveyed 11 ancient clam gardens and 10 un-walled clam beaches
and compared their number size and weight of clams. They collaborated with indigenous knowledge holders from the Tla'amin First Nation and Laich-kwil-tach Treaty Society.

It was the key ingredient for fish tacos which were served then at a residence hall on campus. We were growing tilapia Handler said.
They are a hardy fish that grows well in a controlled environment. They were also the key ingredient in his aquaponics project where fish waste fertilized the plants
and plants kept fish healthy by cleaning their water. It's the same interaction that happens in the natural world said Handler operations a senior research engineer at Michigan Tech.
We just managed things with tanks and pipes. Once the aquaponics project was completed the tilapia were turned over to Michigan Tech Dining Services and wound up on the lunch tables at Wadsworth Hall.
The fish tacos were a resounding success combined with coleslaw made of carrots and cabbage from the residence hall's organic garden.

#Algae research gives hope for renewable carbon-negative source of food, medicinesthe University of Greenwich has won funding for three pieces of research related to algae.
Algae have huge potential as a next generation renewable resource to manufacture a whole range of essential products including food medicines and fuel.
The challenge is to grow and process them in a way which delivers that potential sustainably. The three stories are told separately to aid clarity:
Algae research gives hope for renewable carbon-negative source of food and medicinesbright pink-orange microalgae found in salt lakes
Algae are known for their ability to convert CO2 and sunlight into chemical energy five times faster than crops grown in soil.
The race is on to develop a broader spectrum of compounds from algae which can be turned into high-value products including food and medicines.
If we can make algae biorefineries commercially viable we will have developed a new industry founded on an environmentally-kind raw material
By 2020 these algae may also provide us with sustainable fuel--the science is there but at the moment the costs don't add up.
The project hopes to demonstrate the business case for global investment in algae biorefineries and in large-scale production of microalgae within three years in order to raise investment for the first prototype D-Factory in Europe.
Current biofuels may not be sustainable says Dr John Milledge Research Fellow at Greenwich and an expert in the commercialisation of algae.
Saltwater algae are therefore a very attractive proposition as an alternative biofuel if we can overcome the challenges.
***Algae research into new medicines wins awarddrug discovery company IOTA Pharmaceuticals has chosen the University of Greenwich as its academic partner to research the potential of the microalga Dunaliella as a route to new medicines.

And the broad team of researchers--Pauli tapped entomologists limnologists and bacteriologists--found the algae in samples taken from the stomachs of three-toed sloths.
It could be that even just small amounts of the algae makes ends meet if only because it's so rich in lipids Pauli says.
Having this highly-digestible high-fat algae could be an important input that makes the difference
It's not clear how the algae get into the sloth's stomach or how much of it they're actually consuming.
It may be part of ingesting the algae. Why does the sloth poop in the woods? Maybe because it's hungry.
