Ecosystem services are all the benefits provided to humans by natural systems. These can take many forms ranging from the direct extraction of products, such as wood and timber, to regulating effects such as carbon sequestration and erosion prevention.

With natural systems more and more at risk in light of…

A wooded island surrounded by the ocean.

In 2018, a consultation process was launched in Nova Scotia’s east coast communities to designate an Area of Interest surrounding the Eastern Shore Islands as the 15th Oceans Act Marine Protected Area in Canada.

The Department of National Defence maintains approximately 70 timber Warren truss Air Force Hangars that were built during the Second World War. Throughout the almost 80-year lifespan of these immense buildings, several repair and rehabilitation efforts have occurred to preserve these heritage structures.

However, due to their age and numerous…

The purpose of this trial was to determine when during the growing season and at what rate to surface-apply manure to grassland. This has received little research. Various rates of semi-solid beef manure were applied to timothy in the spring, summer, early, or late fall along with various rates of…

Plants have been used since ancient times as an important source for discovering new drugs for human benefit. Ficus cordata ssp. salicifolia is an evergreen tree (8–15 m) that grows naturally in different areas of the Albaha region (south-western Saudi Arabia). However, the bioactive potential of this plant remains unexplored…

Five years ago we launched FACETS, Canada’s first and only multidisciplinary open access science journal. This year we’re celebrating FACETS’ journey so far, including the official listing of FACETS in the Science Citation Index and the journal receiving its first impact factor (2.535).

We reached this milestone because of the efforts and support of so many, including authors and readers of FACETS — thank you.

Green marshlands sweeping towards a body of water.
Salt marsh in Wolfville Harbour, Nova Scotia.

Coastal salt marshes act as a connection between the land and ocean. They provide crucial services for humans and are important for the proper function of coastal food webs.

These environments allow coastlines to withstand severe weather and prevent erosion of coastal infrastructure. …

Arctic Charr

The lake ecology of Arctic fishes is strongly influenced by seasonal feeding opportunities and environmental variation. Arctic Charr are prevalent throughout the Arctic. They are variable in their growth, number of eggs produced, age when they begin to reproduce and length of life across their range.

Caribou, whooping crane, Gibson’s big sand tiger beetle and dwarf western trillium are among the estimated 80,000 known species (not including viruses and bacteria) in Canada. Of these, scientists have enough information on almost 30,000 species to know that about 20 per cent are imperilled to some degree.

When Canada developed its first national Biodiversity Strategy in 1995, it did so under the assumption that a strong foundation of laws and policies was already in place. Twenty-five years later, however, prevailing biodiversity trends indicate otherwise.

Offspring of fathead minnows that were exposed to metformin during their life cycle.

Metformin is a pharmaceutical drug widely used to treat diabetes in humans by lowering glucose production and absorption. It is taken at doses of about 500–1000 mg daily and is excreted by the kidneys in urine.

Metformin can be degraded by microbes in sewage treatment plants but some of it…
