Nouvelle expo de mon travail sur le rivage à St Herblain au restaurant Polaris.
" Estran, mon délicat rivage " est à voir jusqu'au 26 septembre en dégustant l'un des fameux et délicieux smørbröd de Camilla.

Sand dollar community, half hidden under the sand. Dozens of sand dollars, overlapping each other. New blog post: wanderinweeta.blogspot.com/... #VancouverIsland #Invertebrates #MarineInvertebrates #IntertidalInvertebrates #Intertidal #Nature

Sand on a beach, all covered with lumps. Every lump conceals a sand dollar or two. Some circular shapes are  visible.

A very pretty little shore crab (Hemigrapsus oregonensis) I found on the beach. Usually these are mostly greyish-green, but this one seems to have its own style in mind.

A very close-up photo of a tiny crab with red, slightly purple coloration across its body. The crab is walking away from the camera, across a surface of seaweed, mussel shells, and gunk.

@alcootatooter also and just for good measure :awesome: #wildoz
"There are about 1000 species of #Chiton worldwide, Australia has about 150 species and 90% of these are native to #Australia. Most species are quite small (between 2 and 5 cm long). The largest rarely exceed 30 cm. All chitons are marine living, in cold water and in the tropics, mostly in #intertidal or #subtidal zones." mesa.edu.au/molluscs/molluscs_

We are attending an online training for the beach naturalist program at #SeattleAquarium Tonight’s program features two topics: Queer Ecology and Seastars (latest updates). Here’s a link to a calendar of dates and maps of where, which eastern Puget Sound beaches we will be exploring this season. Join us! seattleaquarium.org/explore-th #SalishSea #invertebrates #algae #seagrasses #intertidal

That red-purple mass between the rocks is a colony of starfish having a snooze in the sun (I'm assuming, there was zero movement, I'm guessing they're waiting for the tide). https://en.wikipedia.org/wiki/Pisaster_ochraceus

I didn't go too close, but a rough estimate would say 30-50 of them, at first sight (partly out of frame). No idea how many submerged.

In this study of Nypa fruticans, a mangrove #palm sp. with origins dating back to the Late #Cretaceous, Wu et al. investigate long-term #adaptation strategies to #intertidal environments and the early #evolution of palms. onlinelibrary.wiley.com/doi/10

Diagram to illustrate early evolution, genome stability, and adaptive traits (specifically waterlogging tolerance and crypto-vivipary) of the mangrove palm Nypa fruticans.

And remember, opposite the #Kingtides are delightfully low tides for you tidepoolers! #tidepool #intertidal sfba.social/@sfbaykeeper/11172

Exceptional analysis of the 2021 #PNW #heat #dome.

OA 🔗 nature.com/articles/s41467-023

Quotes: “…(analyses of) deaths in metropolitan #Vancouver found that they were disproportionately in neighborhoods with higher #material and #social #deprivation and lower levels of #green #space…”

“…over one million #mussels were estimated to have died in a mere 100-m stretch of #shoreline…”

“…the #heatwave killed ~10 million #barnacles along a single 100-m stretch of #intertidal #habitat…”

#ClimateChange 🔥🌡️🌎

Quote fig. 1: “Heatwave daily maximum near-surface (2 m) temperatures (TX). a ERA5 reanalysis data maximum 3-day running mean (between 23 June and 02 July 2021) of TX anomalies relative to a daily 1981–2020 climatology (see Methods for more details). b Absolute TX values for 2021 (solid) and 1981–2020 climatology (dashed); black lines: spatial average of ERA5 data over the black box in a, with shading ±1, 2, and 3 standard deviations; red lines: observations from Lytton, British Columbia (BC), denoted by the red triangle in a—missing values from 1 to 5 July are likely due to the wildfire. Black letters and outlines in a show the main Canadian provinces and US states referred to in this study. Gray outlines and letters in a show the eight crop regions in BC, discussed further in the section on Agricultural Yields.”Quote fig. 2: “Exceedance of previous record high temperatures during a the June 2021 Pacific Northwest heatwave, b the July–August European heatwave of 2003, and c the July–August Russian heatwave of 2010. Filled contours show ERA5 since 1950, whilst individual markers show observational station data in Canada; see Methods for record lengths.Quote fig 6: “Thermal images showing extreme high surface temperatures during low tide on 28 June, 2021, on a a rocky intertidal shoreline and b within a mussel bed. Scale bars indicate the range in temperature from the coolest to warmest parts of the image, while the value at the upper left indicates the temperature in the cross-hairs at center. Note that the mussels in b have died and are gaping open. A subset of species impacted by the heatwave are shown in c–i, including c bay mussels, Mytilus trossulus, d Pacific oysters, Magallana (= Crassostrea) gigas, e heart cockles, Clinocardium nuttallii, f leather stars, Dermasterias imbricata, g kelp crabs, Pugettia producta, h dogwhelks, Nucella lamellosa, and i barnacles, Chthamalus dalli (upper portion of image) and Balanus glandula (lower portion of image). See Methods for locations and dates of photos in c–i.”
