1170. Allium kollmannianum Brullo, Pavone & Salmeri

Curtis's Botanical Magazine, EarlyView.
Summary Allium kollmannianum is a small, late‐spring to early‐summer blooming Allium, endemic to the Negev Desert in south Israel, and previously thought to be extremely rare and critically endangered. Here we expand new information regarding its distribution and habitat in the Negev Desert, and a new estimation of its threat level, considering the new

1177. Streptocarpus aylae T.J.Edwards

Curtis's Botanical Magazine, EarlyView.
Summary Streptocarpus aylae T.J.Edwards, a spectacular, rosette forming herbaceous perennial from cliffs of the Msikaba River in Pondoland, Eastern Cape Province, South Africa is illustrated and discussed. The species is known from only two sites and is highly localised, growing in humus rich cracks and crevices on sandstone cliffs.

Threatened cockatoo adapts foraging strategy to survive habitat loss from fire

Ibis, EarlyView.
Fire regimes are changing across the globe as a result of human‐induced climate change. For granivorous bird species, changes in fire regimes can affect seed availability and the persistence of populations. We investigated the foraging behaviour of Glossy Black Cockatoos Calyptorhynchus lathami halmaturinus, a resource specialist, following large‐scale

A bristle‐nosed Jurassic ray‐finned fish (Actinopterygii) bears true dermal odontodes on its snout

Journal of Anatomy, EarlyView.
Teeth show extreme diversity, including tooth‐like dermal odontodes or “skin teeth” in many extant fishes. We describe the anatomy of enlarged tubercles on the snout of Redfieldius, an extinct early Jurassic fish. We found that the tubercles in Redfieldius are dermal odontodes that evolved independently from those of living species. Abstract Comparison

Comparative histological analysis of vertebrates reveals Triassic climate variability across southern Pangea

Journal of Anatomy, EarlyView.
Bone tissues of Triassic taxa reveal life history signals consistent with climatic variation across southern Pangea, spanning present‐day Brazil, Argentina, Zimbabwe, and India. Slower growth patterns within the Zimbabwean assemblage suggest a comparatively more arid intracontinental environment than those closer to the coast. Artwork by Andrey Atuchin.
