Jorge Brito hanging flower (Ceratostema jorgebritoi) and Siete Iglesias hanging flower (Ceratostema sieteiglesiana)

Jorge Brito hanging flower (Ceratostema jorgebritoi) dan Siete Iglesias hanging flower (Ceratostema sieteiglesiana)

NEWS - Ceratostema jorgebritoi has unique spirally arranged leaves and is the second species in the genus with tetrameric flowers. Ceratostema sieteiglesiana is distinguished by its spirally arranged leaves and distinctive five-winged hypanthium, further enhanced by conspicuous calyx branches. Both are new species.

Jorge Brito hanging flower (C. jorgebritoi) is similar to C. flexuosum (A.C. Sm.) J.F. Macbr., but has tetrameric flowers with oblong (vs. lanceolate) petal lobes, 5-9 acuminate (vs. 3-5 acuminate) and spirally arranged (vs. distichous).

Terminal inflorescence (vs. axillary), larger floral bracts (26.0×9.5 mm vs. 4.0-5.0×2.0 mm), longer hypanthium (3.4-10.1 mm vs. 3.0-4.0 mm), lanceolate-deltaic calyx lobes (vs. oblong) with a pointed apex (vs. acuminate) and narrow triangular corolla lobes (vs. lanceolate).

The species is found in Gualaquiza, Morona-Santiago, southeastern Ecuador. It grows in the eastern Andean foothills at elevations of 1600-1800 meters in primary forest and disturbed secondary areas. The researchers propose a conservation status of EN (Endangered). The name is dedicated to Jorge Brito-Molina, a biologist who has made significant contributions to terrestrial amphibians and micromammals.

Siete Iglesias hanging flower (C. sieteiglesiana) is similar to C. zamorana M.M.Jiménez & Vélez-abarca, but leaves are smaller (1.7-5.5×0.6-2.5 cm vs. 7.7-12.7×3.7-6.5 cm), inflorescences are short to very short-stalked (vs. long-stalked), flower parts are pubescent (vs. pruinose), flower stalks are shorter (1.92.7 cm vs. 2.2-4.1 cm) and subterete (vs. subquadrangular).

Bracteoles subulate (vs. ovate), calyx lobes longer (12.7-19.1 mm vs. 11.3-12.5 mm), sinus and apex pointed (vs. acuminate), corolla lobes longer (28-30 mm vs. 15-16 mm), outer black (vs. magenta) and filaments longer (9.5-13.1 mm vs. 4.5 mm).

C. sieteiglesiana is endemic to the forests around the city of San Juan Bosco, Morona-Santiago, Ecuador. The new species was found at 1500-1700 m elevation in a layered forest containing trees and saplings covered with moss. Conservation status EN (threatened). Named after the type location of this rare species, the Municipal Conservation ecological area Siete Iglesias.

Humpback whales (Megaptera novaeangliae) manufacture bubble-nets as tools to increase prey intake

NEWS - Humpback whales ( Megaptera novaeangliae ) create bubble net tools while foraging, consisting of internal tangential rings, and actively control the number of rings, their size, depth and horizontal spacing between the surrounding bubbles. These structural elements of the net increase prey intake sevenfold. Researchers have known that humpback whales create “bubble nets” for hunting, but the new report shows that the animals also manipulate them in a variety of ways to maximize catches. The behavior places humpbacks among the rare animals that make and use their own tools. “Many animals use tools to help them find food, but very few actually make or modify these tools themselves,” said Lars Bejder, director of the Marine Mammal Research Program (MMRP), University of Hawaii at Manoa. “Humpback whales in southeast Alaska create elaborate bubble nets to catch krill. They skillfully blow bubbles in patterns that form a web with internal rings. They actively control details such ...

Matchbox bean (Entada phaseoloides)

Matchbox Bean ( Entada phaseoloides ) is a species in the Fabaceae family, a large woody liana with stems up to 18 cm in diameter, dark brown, rough bark, laterally flattened, and spirally twisted. The leaves are bipinnate, up to 25 cm long, with 1-2 pairs of minor leaflets, each divided into 1-2 pairs of pinnules. The pinnules are somewhat leathery, asymmetrical or oblique, up to 10 cm long and 5 cm wide. The inflorescence is a spike-shaped, about 25-30 cm long, bearing numerous sessile flowers. The individual flowers are very small, about 1.2 mm in diameter. The five petals, green with reddish bases, are 3-4 mm long, and the stamens are about 7 mm long. The fruit is a very large, flattened, woody pod or capsule, about 1-1.2 m long and 12 cm wide. It is usually slightly curved and linear, with about 12 segments, each containing a single seed. The seeds are lens-shaped, shiny brown, smooth, 5-6 cm wide and 1-1.5 cm thick. Filipinos used gugo before commercial shampoos were available ...
