Long-term effects of #climate change on juvenile #BullShark migratory patterns https://besjournals.onlinelibrary.wiley.com/doi/10.1111/1365-2656.14140
"warming water temperatures in the #GulfOfMexico have been responsible for delaying the overwintering migrations of juvenile bull #sharks from their nurseries in #Texas #estuaries into the Gulf for the last 40 years."
The #CowichanRiver #estuary is one of the largest & most important in #BritishColumbia. The #watershed drains 90,000 hectares & provides #CriticalHabitat to dozens of #fish species, including #steelhead, #Chinook, #chum, #coho & #PinkSalmon, as well as brown, #cutthroat & #RainbowTrout. But the #Cowichan’s troubles are by no means unique; they are a #CaseStudy for a much larger problem.
#TimberCompanies store #LogBooms all along the #BCcoast, says Jamieson Atkinson, a fish #biologist & program manager for the #Aquatic #Research & #Restoration Centre at #BritishColumbiaConservationFoundation. “It’s shocking.” While #estuaries make up less than 3% of British Columbia’s coast, they provide rich #habitat for 80% of the province’s coastal #wildlife. The #FraserRiver estuary, near #Vancouver on the mainland, supports more than 300 species of #birds & 80 species of fish & #shellfish for at least part of their life cycles.

A cocktail of nasty pesticides in oysters and water in one of the NSW North Coast’s dominant rivers.
"New research led by Southern Cross University has found a cocktail of nasty pesticides in oysters and water from one of the NSW North Coast’s dominant rivers. Samples taken from the Richmond River estuary reveal 21 different pesticides, including a mix of herbicides, insecticides and fungicides. The study is the most comprehensive investigation that has been undertaken into the pesticides entering waterways from agricultural and urban run-off in northern NSW"
"The concentrations of several pesticides exceeded safe environmental guidelines, including atrazine and diuron that are banned overseas. Benomyl was also detected despite being banned in Australia...At present there is little accountability for the downstream impacts from land-based run-off.”

Green macroalga #Caulerpa has replaced #seagrass in #Florida's #IndianRiver Lagoon https://phys.org/news/2023-12-green-macroalga-caulerpa-seagrass-florida.html
The green macroalga Caulerpa prolifera replaces seagrass in a nitrogen enriched, phosphorus limited, urbanized estuary https://www.sciencedirect.com/science/article/pii/S1470160X23011779
Rachel Brewton, Ph.D.: "Loss of #seagrasses in urbanized #estuaries is common, as they are highly susceptible to watershed nutrient and sediment inputs, making seagrasses effective biological sentinels"

#Learn about the biggest #estuary #RestorationProject on #VancouverIsland - to remove two kms of dikes & #restore 70 hectares of #marsh #habitat . #Estuaries make up just 2.3% of #BritishColumbia #coastline but support 80% of its #coastal #plants & #wildlife .
The #NatureTrustOfBritishColumbia & #Cowichan #Indigenous #FirstNations are leading the project.

Hello, I'm Kevin. I love #surfing and most of all surfing at Vilano. I have always lived here in St. Augustine. I really care about doing away with shoreline hardening (seawalls and bulkheads) and protecting the #estuaries. On Day 47 learning Chinese on Duolingo. I am a web applications developer for ~27 years. Other #hobbies; #fishing, #biking, #trail-walking, #camping, #kayaking, #sailing. My wife and I are empty nesters and grandparents.
