clustered broomrape

Aphyllon fasciculatum, the clustered broomrape, is an obligate root parasite in the family Orobanchaceae native to western North America, ranging from British Columbia south through the western United States to Baja California, particularly in arid and semi-arid grasslands, sagebrush steppe, and chaparral. Like all broomrapes, it lacks chlorophyll and derives all water and nutrients from the roots of host plants, primarily composites (Asteraceae) such as sagebrush (Artemisia) and rabbitbrush (Ericameria). The plant produces a clustered arrangement of yellowish-purple to brownish tubular flowers emerging directly from the soil surface, giving the appearance of a dense cluster of floral spikes without any apparent above-ground vegetative structure. Germination is triggered by chemical signals from host roots. The species is considered an important component of native arid land ecosystems, though broomrapes are sometimes viewed as agricultural weeds where they parasitize crops. A. fasciculatum has not been formally evaluated for IUCN conservation status. The genus Aphyllon was recently split from the broader Orobanche to accommodate some New World species based on molecular evidence.

common bubble snail

The common bubble snail (<em>Akera bullata</em>) is a marine gastropod mollusc found in the coastal waters of Denmark, Norway, Portugal, and Sweden. This species typically inhabits terrestrial and aquatic environments including forests and freshwater-adjacent marine areas, often occurring in shallow subtidal and intertidal zones of temperate European seas. It is classified as Least Concern on the IUCN Red List. As a member of the family Akeridae, the common bubble snail is characterized by its thin, fragile shell and its ability to swim briefly by flapping its large, wing-like parapodia. The species often forages on algae and detritus in sandy and muddy seafloor habitats, particularly in sheltered bays and estuaries. The common bubble snail typically aggregates in large numbers during the spawning season, producing gelatinous egg masses. Biological traits of this species remain poorly documented in the scientific literature.
