Molluscan Mystery in Acadia: An Aeolid Nudibranch Possibly New to Science by Jovan G. Grollino “At this point, we had enough morphological distinctions to realize our species had a chance of being undescribed, but we couldn’t go any further in distinguishing it from the known species without collecting a live, adult specimen in order to observe the egg laying and development.“ The Observer 2026, issue 1

“During 2025, I conducted extensive seaweed sampling along the Coast of Maine, from Kittery to Lubec. I was surprised to find that Grateloupia turuturu had spread eastward from the western side of the Piscataqua River in New Hampshire, where Dr. Mathieson documented it at Hilton Park on Dover Point in 2017. Numerous populations now occur throughout the Piscataqua, extending south and eastward to the York River.” Range Expansion of Grateloupia turuturu, an Invasive Red Alga, on the Coast of Maine by Jordan Chalfant. The Observer 2026 issue 1

“Perhaps the most notable observations were of Bembix pallidipicta, also known as the Pale-painted Sand Wasp. Records of this species across the continent are scant, particularly in the Northeast. Prior to 2022, the species appears not to have been documented in Maine. Recent efforts by expert wasp observers on iNaturalist have seen a small number of observations identified within the state.”

“While I reveled in this close encounter, I spotted another flock of shorebirds approaching. Prepared for their arrival, I was able to get some whole flock and close up images that revealed that they were all Red Knots, 32 in total. The previous high count here had been 24 in 1981 by the renowned Maine ornithologist, Peter Vickery, a number just equaled in this area by a local birder.” The (Gray) Red Knots by Lewis Holmes.

“The Ducktrap River in Waldo County, Maine is the only river in the United States with a self sustaining population of totally wild Atlantic Salmon...There is no stocking...The genetic makeup of the Atlantic Salmon and sea run Brook Trout in the Ducktrap is believed by biologists to be a distinct population, adapted by natural selection to the particular hydrographic features of the Ducktrap watershed.” Ducktrap Monitoring Program 2025 by Georges River Chapter of Trout Unlimited.
