Found 10 records similar to Inland waters lakes and streams – biological communities
This data set includes information on water quality of lakes and streams across Ontario since 1976. It includes: * major anions and cations * nutrients * chlorophyll * metals Data were collected as part of routine monitoring of water quality of inland waters and for scientific and research purposes.
This dataset contains information on benthic invertebrate community structure of samples collected from nearshore index monitoring stations within a Great Lake basin each year. The composition of benthic invertebrates (such as insects, worms, mussels, snails and crayfish) found in a sample is used as a biological indicator of trophic status and general environmental conditions to help understand ecosystem function, structure and change. Surveys are typically conducted in one of the Great Lakes basins each year. In most cases, five replicate samples (600 μm mesh, 9-inch ponar) were collected at each station.
Phytoplankton pigments, determined by high-performance liquid chromatography (HPLC) are measured seasonally along a 20-station transect in the Juan de Fuca / Strait of Georgia Basin. Sampling was initiated in 2004, discontinued in 2012 and restarted in 2015. In addition, occasional sampling is carried out at several locations and times in inland waters.

This data set includes information on sampling locations and physical conditions in lakes and streams across Ontario. It also includes meteorological conditions from monitoring stations in south-central Ontario. Lakes The data for lakes includes sampling location details and measurements such as: * temperature * dissolved oxygen levels * water transparency Streams The data for streams includes measurements such as stream flow discharge from monitoring stations in south-central Ontario. Meteorological conditions This dataset contains meteorological conditions for climate stations close to monitored lakes in south-central Ontario.
Recent observations suggest that shallow lakes and ponds in the Arctic are becoming increasingly dynamic in response to climate change, and changes in water levels, lake surface area, and biological communities have been observed at several high-latitude locations. The Old Crow Flats, located 25 km north of Old Crow in the northern Yukon, is a Wetland of International Importance recognized by the Ramsar Convention. Portions of the Old Crow Flats are protected by Vuntut National Park and the Old Crow Flats Special Management Area. The Vuntut Gwitchin First Nation has observed reduced lake levels over the past few decades and are concerned about how the changing landscape may affect the ecology of the region and their traditional lifestyle.
Get data about the water quality for Ontario's inland lakes. The data is collected through volunteer monitoring efforts – citizen science. The Lake Partner Program (LPP) measures water quality in inland lakes across Ontario. This dataset provides water quality and water clarity data, as well as data on the concentrations of: * total phosphorus * calcium Spatial information for lake monitoring locations across Ontario are also available.
A biosimilar is a biologic drug that is highly similar to a biologic drug that was already authorized for sale. Health Canada authorizes biosimilars for sale using the same rigorous regulatory standards for quality, efficacy and safety as for all other biologic drugs.
This dataset consists of the seventy-three (73) provincial limits of inland fisheries. It was generated from descriptions in Schedule II of the Federal Fisheries Act and from various Service New Brunswick databases.
Contained within the 4th Edition (1974) of the Atlas of Canada is a map that shows lakes and rivers licensed for commercial fishing for the period 1963 to 1964 as well as salmon spawning rivers and lakes. The number of inland fisheries plants is also indicated. The map is accompanied by supplemental graphs and text showing the average annual landed value by leading and minor species for the period 1959 to 1963 as well as territorial percentages of national value of inland commercial fisheries.
Identification of ecological and biological significant areas (EBSA) in the Estuary and the Gulf of St. Lawrence according to six groups of the food chain : primary production (Lavoie et al, 2007), secondary production (Plourde et McQuinn, 2010), meroplankton (Ouellet, 2007), benthic invertebrates (Chabot et al, 2007), demersal fishes (Castonguay et Valois, 2007) and pelagic fishes (McQuinn et al, 2012). The distribution area of each group has been evaluated using five criteria in order to determine the EBSA (DFO, 2004):
- Uniqueness: Ranked from areas whose characteristics are unique, rare, distinct, and for which alternatives do not exist to areas whose characteristics are widespread with many areas which are similar. 2.
