In kyu Lee alga (Aglaothamnion inkyui) from Korea closely related to Aglaothamnion pseudobyssoides

NEWS - Researchers collected red algae from the east coast of Korea and phylogenetic analysis using rbcL sequences and two DNA-based species delimitation analyses revealed the specimens to be a new species, In kyu Lee alga (Aglaothamnion inkyui E.Shim & G.H.Kim sp. nov), which is closely related to A. pseudobyssoides.

Aglaothamnion was assigned by Feldmann-Mazoyer (1941) to species previously placed in the genus Callithamnion, with the type species A. furcellariae (J.Agardh) Feldmann-Mazoyer (1941: 454), which was later synonymized with A. tenuissimum (Bonnemaison) Feldmann-Mazoyer (1941; 469).

Currently 35 Aglaothamnion names are accepted and 3 of them are recorded from Korea: A. callophyllidicola (Yamada) Boo, I.K.Lee, Rueness & Yoshida (1991), A. chejuense (G.H.Kim & I.K.Lee) and A. oosumiense Itono (1971). Now Eunyoung Shim and Gwang Hoon Kim from Kongju National University in Gongju and colleagues examine the new collection as a new species of red alga.

A. inkyui has a thallus is uniseriate, thin, up to 4 cm high, attached at the base by multicellular rhizoids. No reproductive structures were seen. Branching is dichotomously alternate, sometimes branches appear at irregular intervals at the bottom of the axial cells.

Freshly collected thalli are reddish in color with a light brown hue. Near the base of the thallus, the initial regular dichotomous pattern is sometimes less easy to observe. Branching results in a marked zig-zag arrangement of the axial cells in the apical parts of the thallus. Mature axial cells, ca. 10 cells below the apex, are longer than wide (30-60 mm by 300-500 mm; L/W: 2–8:1).

Lateral branching is of 2-3 orders; the apical cell is blunt. All cells are uninucleate. The average nuclear size is 10x15 μm in the main axial cells, while the newly growing cells at the tip had smaller nuclei, averaging 4x6 μm.

The species is distributed in Sungeut Beach, Gangneung-si, Gangwon-do, South Korea. It is mostly found on tidal rocky substrates. The fibrous thallus is attached to hard rocky substrates. This is a new species record of South Korea. The name honors Professor In kyu Lee for his many years of psychological research in South Korea.

Black jumping spider (Hyllus diardi)

Black jumping spider ( Hyllus diardi ) is an animal species in the Salticidae, black and white spiders, long hair, round head, elongated belly, relatively small, arboreal, perched on leaves in bushes and low trees in forests and agricultural lands. H. diardi has black and white color, shiny surface and white hair all over the body. The head is round, shiny black with a linear white line in the middle. Black eyes on the front of the head. The stomach has an elongated, jointed, black cylindrical shape with black plots at the top of each segment. The legs are long, segmented, shiny black or brownish in color and hairy. Black jumping spiders live arboreal, perch on leaf surfaces, low bushes, trees in forests, agricultural land, roadsides and shade. Very sensitive to human presence and will hide behind leaves to avoid sight. Kingdom: Animalia Phylum: Arthropoda Subphylum: Chelicerata Class: Arachnida Order: Araneae Suborder: Araneomorphae Infraorder: Entelegynae Superfamily: Salticoi...

Hairy senna (Senna hirsuta)

Hairy senna ( Senna hirsuta ) is a species of plant in the Fabaceae family. It is an upright shrub, growing up to 2.5 meters tall. The leaves are compound on petioles up to 13 cm long. They usually have 2-6 pairs of leaflets, are egg-shaped, and have white hairs, up to 10 cm long and 5 cm wide. The flowers are yellow and arranged at the tips of branches and in the upper leaf axils in clusters of 2-5. The petals are 12-16 mm long, have 6 stamens, 3-8 mm long anthers, and 4 staminodes. Flowering occurs almost monthly. The pods are cylindrical, up to 15 cm long, 4-6 mm wide, and curved.

Awar awar (Ficus septica)

Awar-awar or lagnob or hauli tree or barabar or sirih popar or tobo tobo ( Ficus septica ) is species of plants in Moraceae, trees grow in bushes or in neglected places and sap contained in roots, twigs, leaves and fruit is used to treat poisoning and digestive problems. F. septica is usually 1-5 m high, although in the forest it can be up to 25 m. Round, hollow and bare branches. Roots, twigs, leaves and fruit will emit a yellow sap and sticky if injured. The base of the leaves is large and spiky, arranged alternately or face to face with a stem length of 2.5-5 cm. Large leaf blade, round egg, 9-30x9-16 cm, rounded base and blunt narrow tip, flat-edged, upper side dark green with 6-12 secondary bones pale white. Fruit paired, single or clustered up to 4 items, short-stemmed, at the base has 3 protective leaves, light green or gray green and 1.5 cm in diameter.
