Voilà ce que l'on voit à marée basse dans la baie du Mont St Michel.
Espèce ingénieur de son écosystème, l'hermelle donne naissance à une bioconstruction dont les individus coloniaux érigent des tubes formant le massif ou récif d'hermelles. Les tubes de sable ont une section circulaire de 5 à 10 mm de diamètre, cimentés par une glande du ver, sont droits et forment un ensemble à l’allure buissonnante.
This is what you see at low tide in the bay of Mont St Michel.
An engineer of its ecosystem, the hermella gives rise to a bioconstruction whose colonial individuals erect tubes forming the hermella mass or reef. The sand tubes have a circular cross-section of 5 to 10 mm in diameter, cemented by a gland of the worm, are straight and form a bushy-looking whole.
“Urban Ecosystem Restoration” mural painted by Millo for Street Art For Mankind
From the Street Art For Mankind instagram post:
It features the artist’s signature clumsy character in a surreal setting, attempting to reclaim his space in an urban jungle that has forgotten our primary needs. It poetically and powerfully underscores the importance of green spaces in urban environments. The character demonstrates the strength of these spaces, their transformative impact on our reality, and how they enhance our well-being. It’s a clear invitation to reconnect with nature in our cities.
Picturesque framing of great egrets hunting in a rich intertidal ecosystem, algae-covered rocks and tide pools.
These birds are characterized by their entirely white plumage, long legs, long necks, and pointed beaks
They are typically found in shallow waters, including coastlines, marshes, and lagoons, where they wade to hunt for fish and other small aquatic animals.
Great egrets are known for their elegant and graceful landings, often described as smooth and deliberate, with their long legs and wings outstretched as they approach their landing spot

Seen in the arboretum in Rogów :)
The Rogów Arboretum, established in 1925, is the Station of Protection and Shaping of Forest Ecosystems. It covers an area of 54 ha and is of an exceptional character as compared with other centers of the type in Poland or Europe, because it has been built from the very beginning as a research – didactic object and, moreover, it was located in the forest and has been tightly connected with the forest experimental study from the moment of its origin. The Arboretum consists of three basic parts: the dendrological collections (about 22 ha), the forest experimental plots (about 18 ha) and the alpine garden (1.5 ha).
The dendrological collections that is tree and shrub individuals planted either separately or in groups or small area forms, are mainly concentrated in the central and southern part of the Arboretum, covering a total of 2350 species and varieties. The Arboretum’s specialty is its collection of maples and shrubs from China. This segment is managed naturally, having the look of more a forest park than a typical botanical garden. The trees give the shelter and the proper microclimate for the introduced trees and shrubs.

Biały rododendron w arboretum w Rogowie :)
Arboretum w Rogowie – należy do grupy najcenniejszych, najbogatszych w gatunki i odmiany drzew i krzewów tego typu ogrodów w Europie. Położony jest w dawnym siedlisku leśnym i ma charakter parku leśnego. Od początku istnienia (1925 r.) podlega pod Wydział Leśny SGGW. Na jego obszarze znajdują się jedne z najbogatszych i najciekawszych kolekcji drzew i krzewów Europy Środkowo-Wschodniej. Najchętniej odwiedzanym miejscem w ogrodzie jest alpinarium. Oprócz wyniesionych na 2 m ponad poziom gruntu skalniaków, założono tu ciąg strumyków, kilka oczek wodnych i 5-arowy staw z wyspą. W rogowskim alpinarium można obejrzeć ponad 400 gatunków i odmian roślin, pochodzących z gór całego świata. W większości są to byliny, ale nie tylko. Rosną tu także krzewy i drzewa terenów górzystych, np. majestatyczne świerki serbskie, kształtne limby czy srebrzyste jodły kalifornijskie.
In addition to the impressive peaks, Grand Teton National Park is an almost pristine ecosystem and the same species of flora and fauna that have existed since prehistoric times can still be found there.

“Sally Lightfoot crabs are brightly-coloured coastal scavengers, found in the Galapagos Islands and across the western coast of South and Central America. They have an extremely generalist diet, feeding on anything from sea lion placenta to other crabs. This makes them an important part of the ecosystem, as they provide services such as keeping the shore clean of any organic debris and eating ticks off marine iguanas. They are rumoured to have been named after a Caribbean dancer, due to their agility in jumping from rock to rock, their ability to run in four directions and their capacity to climb up vertical slopes. This extreme agility makes them very difficult to catch. Adult crabs show characteristic intense blue and red colouring on their shells, with a white or pale blue underbelly. Younger crabs have darker colouration with red spots, providing a higher degree of camouflage. Every time the crabs moult their shell, the spots become gradually larger, until they obtain the adult colouring.
Female Sally Lightfoot crabs carry their eggs around with them on their stomachs until they hatch into the water. The larvae then swim out to deeper waters, where they consume phytoplankton and undergo a rapid series of moults. Eventually they undergo metamorphosis to become juvenile crabs and swim to shore, where they start to scavenge, becoming bigger and more colourful with each moult. These juveniles tend to travel in large groups until they reach maturity, after which they become largely solitary when not mating. When they are not mating or feeding, the crabs spend their time hiding in cracks in rocks. If they are disturbed, they may spray water or shed one of their legs as a defence mechanism.”

Continuing my coastal ecosystem series with this preening Brown Pelican.
Brown Pelicans live in estuaries and coastal marine habitats along both the east and west coasts. This one was found perched and preening atop a weathered wharf pole near a fish cleaning station in Lamar, Texas.
Another coastal ecosystem resident is this Black Oystercatcher.
From the Cornell Lab:
"Among the mussel- and barnacle-covered rocks of the Pacific Coast lives this stout shorebird with a gleaming reddish bill, yellow eyes, and pink legs. Black Oystercatchers spend their entire lives in view of the Pacific Ocean or adjacent bays, in rocky marine habitats that provide both nesting and foraging areas."
This one was foraging on the jetty in Crescent City, California.
A striking view of the coastal mangrove ecosystem at low tide. The muddy forest floor is covered with thousands of pneumatophores—the unique upward-growing "breathing roots" that allow these resilient trees to survive in the waterlogged, tidal environments of the delta. Through the slender trunks and lush green canopy, a quiet waterway and a distant boat hint at the deep connection between the forest and the riverine communities.

Le Hopewell Rocks Park, au sud de Moncton, Nouveau-Brunswick, Canada. Situé au débouché de la rivière Petitcodiac, sur la baie de Shepody, le Hopewell Cape est célèbre pour ses falaises de conglomérat rouge dont l'érosion a détaché de pittoresques rochers parfois coiffés d'épinettes noires (épicéas) et de quelques sapins baumiers. À marée haute, ces rochers forment de petits îlots et lorsque la mer se retire on aperçoit leur base étrangement rétrécie par le frottement de l'eau qu'on surnomme alors rochers en "pot-de-fleur".
Des panneaux d’interprétation sur chaque belvédère du parc aident les visiteurs à mieux comprendre les écosystèmes uniques de la baie de Fundy reconnue comme ayant les marées les plus hautes au monde. Des interprètes amicaux et bien renseignés sont partout dans le parc pour répondre directement aux questions ou aider les visiteurs.
Brittle stars, an alternate common name is the 'serpent stars', are a species-rich class of echinoderms with outstanding regenerative abilities. Living under rocks or in crevices with only the tips of the arms exposed, they are known to be seafloor ecosystem engineers. They reshape the seafloor sediment surface and influence the distribution of other seafloor species. They also provide nutrition to fish, sea stars and crab predators.
Their presence in a sediment sample is one indicator of a healthy benthic community. They embody nature's fragility and resilience.

American Bison
The American Bison or simply Bison (Bison bison), also commonly known as the American Buffalo or simply Buffalo, is an American species of Bison that once roamed North America in vast herds. Its historical range, by 9000 BC, is described as the Great Bison Belt, a tract of rich grassland that ran from Alaska to the Gulf of Mexico, east to the Atlantic Seaboard (nearly to the Atlantic tidewater in some areas) as far north as New York and south to Georgia and, according to some sources, further south to Florida, with sightings in North Carolina near Buffalo Ford on the Catawba River as late as 1750. It nearly became extinct by a combination of commercial hunting and slaughter in the 19th century and introduction of bovine diseases from domestic cattle. With a population more than 60 million in the late 18th century, the species was down to just 541 animals by 1889. Recovery efforts expanded in the mid-20th century, with a resurgence to roughly 31,000 wild Bison today, largely restricted to a few national parks and reserves. Through multiple reintroductions, the species is now also freely roaming wild in some regions in the United States, Canada, and Mexico, with it also being introduced to Yakutia in Russia.

Les insectes du monde entier sont en voie d'extinction , Plus de 40 % des espèces d'insectes sont en déclin et un tiers sont menacées, selon les chercheurs. Leur taux de mortalité est huit fois plus rapide que celui des mammifères, oiseaux et reptiles. Au cours des trente dernières années, la masse totale des insectes existant dans le monde a diminué de 2,5 % chaque année. A ce rythme, s'inquiètent les scientifiques, ils pourraient disparaître d'ici à un siècle. « C'est très rapide. Dans dix ans, il y aura un quart d'insectes de moins, dans cinquante ans, plus que la moitié, et dans cent ans, il n'y en aura plus » Les insectes sont « essentiels » au bon fonctionnement de tous les écosystèmes, expliquent les chercheurs. Ils pollinisent les plantes, recyclent les nutriments et servent de nourriture de base aux autres animaux. Leur disparition « aura des conséquences catastrophiques à la fois pour les écosystèmes de la planète et pour la survie de l'humanité » L'un des impacts majeurs concerne les nombreux oiseaux, reptiles, amphibiens et poissons qui se nourrissent d'insectes. « Si cette source de nourriture leur est enlevée, tous ces animaux mourront de faim » , « Si nous ne changeons pas nos méthodes de production alimentaire, les insectes dans leur ensemble s'engageront sur la voie de l'extinction dans quelques décennies », écrivent les chercheurs, pour lesquels l'agriculture intensive est la cause principale du déclin des populations d'insectes, en particulier la forte utilisation des pesticides. L'urbanisation et le changement climatique sont également des facteurs importants.

Britain’s largest social wasp, the European Hornet is native to the UK and Europe, as well as being established in both North and South America - it’s latinate name is Vespa Crabro. A subfamily of the Vespinae, these members are characterised by habits that include chewing up their food to feed to their young, and chewing up materials to create paper-like nests.
Due to their colouring, European hornets are often mistaken for the Asian Giant Hornet - which are a more dangerous species that is not native to the UK. Though we do not know when the first hornet was sighted in the UK, it is believed that the
Due to the unwarranted fear surrounding European hornets, many of their nests in the past have been destroyed - leading to them becoming critically endangered. It is no secret that we need to do more to protect the natural ecosystems and biodiversity that is in place. That is why in some countries like Germany, it is illegal to kill or harm a European wasp nest. Though we don’t have this law in the UK - it signals to us how important it is to protect the decline of these species.

The organisms in the riparian zone respond to changes in river channel location and patterns of flow. The ecosystem of rivers is generally described by the river continuum concept, which has some additions and refinements to allow for dams and waterfalls and temporary extensive flooding. The concept describes the river as a system in which the physical parameters, the availability of food particles and the composition of the ecosystem are continuously changing along its length. The food (energy) that remains from the upstream part is used downstream.
The general pattern is that the first order streams contain particulate matter (decaying leaves from the surrounding forests) which is processed there by shredders like Plecoptera larvae. The products of these shredders are used by collectors, such as Hydropsychidae, and further downstream algae that create the primary production become the main food source of the organisms. All changes are gradual and the distribution of each species can be described as a normal curve, with the highest density where the conditions are optimal. In rivers succession is virtually absent and the composition of the ecosystem stays fixed in time.
The Female Multicolored Tanager (Chlorochrysa nitidissima), photographed at La Minga Ecolodge near Cali, Colombia, is a striking representation of the vibrant biodiversity found in the Andean cloud forests. This delicate bird, with her emerald-green plumage, golden-yellow face, and soft blue undertones, perched gracefully on a slender branch amidst lush greenery. The diffused forest light illuminated her vibrant colors and intricate feather details while creating a soft, natural backdrop that emphasized her presence.
To capture this image, I used a Canon R5 paired with the RF 100-500mm lens at its maximum focal length of 500mm. A shutter speed of 1/500 second froze the tanager’s subtle movements, while ISO 800 ensured clarity and vibrancy in the low-light conditions of the dense forest. The combination of technical precision and patience was key to highlighting the beauty of this elusive species. Collaborating with local birding guide Asherita Viajera added depth to this experience, making it possible to observe and capture this stunning moment. This photograph reflects the importance of preserving such habitats and the species that thrive within them.

Hey fellow reef enthusiasts and followers!
About eight months ago, I faced a challenging moment in my marine adventure. While I was away on vacation, the caretaker of my beloved reef tank accidentally dosed it with a chemical that led to a complete wipeout. After a decade of nurturing a vibrant ecosystem filled with both hard and soft corals, it was a tough blow.
However, as any marine biologist will tell you, maintaining a delicate balance of hard and soft corals in a home reef tank is an art that comes with challenges and a thin margin for error. Each species has its own unique requirements, making their cohabitation tricky but incredibly rewarding.
Now, after seven months of hard work and dedication, I’m excited to share this photo of my complete restart! While it’s heart-wrenching to face setbacks like this, it’s also a chance to learn, rebuild, and create something even more spectacular. Join me on this journey as I work to establish a thriving reef community once again!
Happy reefing, everyone! 🌊✨

Moose of Grand Teton
Moose are the largest member of the deer family and love cold weather. They frequent marshy meadows and edges of lakes and streams. About 800 Moose inhabit the southern part of Yellowstone, Grand Teton National Park and surrounding national forests. Moose are most heavily concentrated in Grand Teton Park.
To keep from sinking in mud while feeding, as the animal lowers its foot, a large dewclaw spreads to better support the weight. Similarly, the odd-looking crook of the hind leg allows a Moose to pull the leg straight up, more easily releasing it from deep, sucking mud.
Bull Moose lose their antlers anytime between December and March. Most of the Moose drop them in January. Immature bulls may not shed their antlers for the winter but retain them until the following spring. Female Moose do not have antlers.
A new set of antlers begin to grow the following spring, nourished by the covering of furry skin known as velvet. They take three to five months to develop fully – the velvet is then scraped and rubbed off against bushes and branches. The antlers are then ready for battle. Generally, each set of antlers will be larger than the one before.
Birds, carnivores, and rodents eat dropped antlers as they are full of protein and Moose themselves will eat antler velvet for the nutrients.
Take note—cow Moose with young can be particularly dangerous.

Calm waters reflect the tidal sedge grasses and the lush rainforest environment of the Pacific Northwest, the largest, almost roadless temperate rainforest ecoregion on the planet. North Pacific coastal forests are home some of the tallest species of trees, dominated by western red cedar, Sitka spruce, and western hemlock. Dense growths of epiphytes and mosses cover the trees, and lush vegetation is present everywhere. Indeed, in terms of biomass, these forests are the most massive ecosystems in the world.

"Hoback at sunset."
“In the Tetons, two bull moose seem to get all of the attention: Hoback and Shoshone. There are several other majestic bulls, but over the past couple of years, the dynamic duo has become the stars of the show. Both are stunningly large and relatively “dependable” subjects. There are times, especially early and late in the season, when you might see them together, as they share much of the same territory. Over a period of three or four years of photographing them, I can suggest they enjoy each other’s company. During the heat of the rut, however, they can become mortal enemies!” By Mike R.
