I am sorry, Ecology class today!
One of the most important limiting factors for aquatic fauna in mountain creeks is trophism. In every ecosystem on Earth the main energy source is sunlight, used by photosyntetic organisms to transform some inorganic compounds, water and carbon dioxyde, into organic, mainly glucose sugar. Plants though need more than simple sunlight, as their bodies are also made of proteins and other molecules where Nitrogen and Phosphorus are present as well as Carbon and Hydrogen. The first two elements must be found in the environment, as plants are not able to use athmospheric Nitrogen by their own, and Phosphorus is a relatively rare element. The concentration of N and P are clearly limiting factors for algae and plants growth in many river head stretches.
In that kind of environment algal growth is limited and only microalgae form thin layers on stone surface. Even if the turnover of this organisms is fast, their total biomass is low, so that grazing invertebrates can find poor food sources, while grazing fishes lack.
Energy, Carbon and the so called nutrients (mainly Nitrogen and Phosphorus) are carried into the aquatic ecosystem as organic detritus. This is represented by leaves, wood fragments and dead animals driven into the creek by wind or water rill flow. As soon as leaves are driven into the creek (actually as soon as they leave the tree branch) bacteria and fungi begin their decomposition. On these decomposing leaves a community of microorganisms develops where protozoa prey smaller organisms. Many benthic invertebrates feed cutting and eating fragments of decomposing leaves. These are called detrivorous invertebrates, but are not actually eating leaves, as animals can’t digest cellulose by their own. These cutters ingest leaf fragments and digest the microfauna layer on them. This is the way a large amount of energy and Carbon get into mountain running water ecosystems, the so called detritus food chain. Actually this is simply the most important energy stream into the ecosystem, but the monodimensional concept of “food chain” has been abandoned by ecologists many years ago. It is though an highly intuitive concept, useful in didactic models of freshwater environments.
So, dead leaves are the fuel for aquatic mountain ecosystems. I usually say that the river eats the surrounding forest. A change in forests or lateral river – land connection would change dramatically the energy intake and so the whole system.

The Field Station will afford VI University marine science students the opportunity to conduct field research in Deep Bay and lab work in the lower level of the field station. Some of the students were on hand to tell us about their research and explain the unique centerpieces at each table (shown above right). Each flask held water and live shellfish from the bay and next to it was a flask with murky, algae-filled water. The students advised us to pour the ‘dirty’ water into the larger shellfish-filled flask and watch them go to work. By the end of the delectable meal the water was clear again – a creative demonstration of the important ecosystem services shellfish provide.

The Arctic is a region not easily delineated by one boundary or definition - it includes the Arctic Ocean and the land areas around it, including Greenland, Eurasia and North America. A climate definition of the Arctic is the 10 centigrade July isotherm. This limit roughly coincides with the treeline and represents a change in growing conditions for plants. As visible in the map, this also includes mountainous and alpine areas. The map also presents the Arctic circle at 66°33 North - the limit of the midnight sun and polar night. The Conservation of Arctic Flora and Fauna (CAFF) area presented in the map is the area covered by CAFF working group under the Arctic Council.

By far my favourite combination: an Ecosystem notebook + a black leather VadeMecum Pocket Cover.
The ecosystem notebook is exactly the same as the Moleskine. The cover fits like a glove.
When we stopped at this pond for our "sundowner," my first thought was, "Why couldn't we have stopped somewhere where there was something to see? But after a closer look at the variety of aquatic plants, the old-growth indigenous trees, the weaver-bird nests, and the mist already starting to form, I ended up being the last one back on the truck.
Over the past 40 years, globally, intensification of cultivated systems has been the primary source (almost 80%) of increased output. But some countries, predominantly found in sub-Saharan Africa, have had persistently low levels of productivity, and continue to rely on expansion of cultivated area.

Myanmar 18.09.18 At sea on board “Dr. Fridjof Nansen”
By: Jens-Otto Krakstad, IMR. Cruise Leader
It feels good to be back at sea again, and a pleasure to be back in the waters of Myanmar. After a great reception and a crew change in Yangon in the middle of the survey, the vessel and crew is back at work. The first leg completed more than half of the ecosystem survey, the third one in recent years, and the first with the third “Dr. Fridtjof Nansen”.
The purpose of the survey is as previously to get updated information of the living marine resources and environment in Myanmar waters, and in addition, as a new goal, to identify spawning areas of commercial fish species along the coast. These are areas that should receive special protection to be able to increase fish production in other areas. In addition, this survey is in yet another season (after the Summer (southwest) Monsoon) than the two previous surveys (November-December 2013 (Onset of the winter monsoon) and May 2015 (onset of the Summer Monsoon) complimenting the overall picture of the seasonality of both fish distribution and variability in the marine environment.
On-board are 17 scientists from Myanmar and participants from India (1) and Thailand (2). The inclusion of scientists from neighbouring countries are important to stimulate regional cooperation. In addition, there are 10 scientists and technicians from IMR and FAO that are responsible for the data collection within the different scientific disciplines on board and carry out on-the-job training of the local scientists.
The results from the survey are all very preliminary but we see very important seasonal changes in the ecosystem that we are aware of on a large scale, but which we need to understand in a more local context. We observe a high biodiversity as in the previous surveys and new species not discovered in any of the two previous. In addition, we observe that this season is relative non-productive. Water masses are relatively well mixed in the surface (to 80-90 m) then strongly stratified. Upwelling observed in other periods of the year is now virtually non-existing and primary production is low. This is also reflected in fish biomass who is now possibly at its lowest level seasonally as fish are migrating to other more productive areas.
On-board is a variety of scientific equipment used for our research during this survey. Data on the physical oceanography are collected by a thermosalinograph and a CTD who record environmental parameters like temperature, salinity, oxygen and fluorescence in the water column at selected stations and continuously from the surface water (4 m). For plankton sampling we use four different plankton net with different mesh sizes depending on the type of plankton we search for. Phytoplankton uses a very fine messed net 10 mikron, for zooplankton we use a 180 mikron net called a WP2, while fish egg and larvae are collected with a multinet, and from a so-called manta trawl skimming the surface. In addition, we pump water continuously trough another net to collect fish egg and larvae from the surface. The two last mentioned nets are also used for collection of micro plastic. Plastic pollution and microplastic in the ocean has received considerably attention lately. The Nansen program has recorded plastic in the trawl catches for many years already, but now also microplastic receive special attention and all plastic that we find are carefully recorded, measured and taken to Norway for further laboratory analyses.
Our trawls are historically the equipment that has stayed unchanged the longest. During this survey, we use three different trawls. A bottom trawl for demersal fish, a small pelagic fish trawl and a high speed pelagic fish specially designed for fast swimming species. Once the catch is on board we sort the catch and record the number and weight of all species caught in addition to other biological parameters. Myanmar has an enormous fish biodiversity and all species are carefully identified, while species that cannot be identified will be sent to expert taxonomist around the world.
Another new ting we focus on is food quality. Very little is known about pollution levels; pesticides, heavy metals and other pollutants, in fish flesh. Therefore, fish and fish fillets are collected regularly during the survey, dried, preserved and taken to specialised laboratories to analyse for these substances. This is part of a big international food safety study to identify potential health risks when we eat fish and fish products.

LOS ANGELES--U.S. Army Corps of Engineers Los Angeles District and Los Angeles County officials broke ground Feb. 22 on a project designed to restore degraded habitat in the San Fernando Valley.
Supervisor Zev Yaroslavsky, Public Works Deputy Director Mark Pestrella and District Commander Col. Mark Toy ceremonially turned dirt for the start of the $7 million Tujunga Wash Ecosystem Restoration project that will extend greening along the sides of a 3/4-mile stretch of concrete channel that carries runoff from Hansen Dam to the Los Angeles River.
Corps contractors will construct a meandering manmade stream, complete with native riparian vegetation and pedestrian pathways, on the west bank of the channel between Vanowen St. and Sherman Way. The east bank will be planted with native, drought-tolerant perennials and shrubs. The restoration project will connect to the county's Tujunga Wash Greenway project just to the south, creating a riparian habitat corridor nearly 2.5 miles long.
"Every segment of this wash that we've restored has had their neighborhood just thrilled with the beautification," said Yaroslavsky. "It's just an improvement of the quality of life."
Community residents Stan and Lynne Friedman, among the nearly a dozen community members in attendance at the ceremony, couldn't have agreed more with Yaroslavsky. They've lived along the barren channel for nearly 40 years.
"We're pretty excited about the project," Stan said. "We think it's a great idea."
"It'll be nice to look out at and take a walk in," added Lynne.
Toy told the residents and county partners in the audience that the project will effectively combine flood risk management with ecosystem restoration and recreation.
"We owe this to you, to create a community that you can walk down and enjoy the great outdoors," said Toy. "We have so much momentum right now with the LA River Watershed, not only with America's Great Outdoors Initiative, but the Urban Waters Federal Partnership Program."
Both programs share goals that include reconnecting people to their waterways and promoting water conservation.
According to Pestrella, the project brings multiple benefits that will serve as a model for a sustainable and healthy stream system in a dense, urban area of the valley.
"That water will eventually someday become part of the drinking water here in LA," said Pestrella. "It'll also help us with pollution issues. As pollution reaches the channel and we bring the water up onto the top of the channel, it's recharged eliminating a number of pollutants before it reaches our groundwater again."
Tujunga Wash was channelized in the 1950's curbing flooding in the developing area, but also halting the wash's natural function. Some of that function will be restored, providing opportunities for migratory bird nesting, wildlife movement, recreation and education, none of which will reduce the capacity of the flood control system.
The Corps is funding 75 percent of the project costs under its Continuing Authorities Program, Section 1135 of the Water Resources Development Act, that allows improvement of the quality of the environment in the public interest. Los Angeles County Flood Control District, which operates and maintains the wash, will fund the remaining 25 percent of the total project costs. Construction is scheduled to be completed this summer.
Goal of this FAO-led project is to adopt an integrated ecosystems approach for the management of land resources in the Kagera Basin that will generate local, national and global benefits including: restoration of degraded lands, carbon sequestration and climate change adaptation and mitigation, protection of international waters, agro-biodiversity conservation and sustainable use and improved agricultural production, leading to increased food security and improved rural livelihoods.

The thick-billed murre and common murre have ranges 1,000,000 km2 and number in the millions or tens of millions of breeding pairs. However global populations are declining, although increases have occurred in some regions. These seabirds, together with other species of alcids, face a number of direct and indirect marine and terrestrial threats, which influence their survival and reproductive success. These include transboundary pollutants, by-catch mortality from fisheries, competition with fisheries for fish stocks, disturbance of breeding sites/habitat, and unsustainable harvesting. Marine pollution, especially oil, is a significant threat. Alcids are particularly sensitive to even small oil spills because of their concentrated aggregations. There is also concern over the impacts of cruise ship tourism on Arctic seabird colonies, given its rapid growth. Greater ship traffic increases the risk of groundings and other accidents, which may result in oil spills and other consequences.
