Kearse heydrich biography
- In this study, 50 Korean Reinboldiella specimens, previously known as Reinboldiella schmitziana, were collected from 11 localities and reexamined to verify.
- A new non-geniculate coralline algal species, Chamberlainium tenue, is described from South Africa that was previously passing under the misapplied name.
- The integrative approach established clear taxonomic concepts for the studied genera and species, and identified useful characters for genera.

Abstract
The genus Ramicrusta (order Peyssonneliales) is a new record for Micronesia, with range expansions of Ramicrusta fujiiana and R. lateralis to Guam. In addition, four species (Ramicrusta adjoulanensis, R. asanitensis, R. labtasiensis, and R. taogamensis) are newly described from Guam using molecular and anatomical characters. Ramicrusta lateralis specimens from Guam share most anatomical features with the holotype description from Vanuatu, but the plants from Guam are more tightly adherent, rigid, and robust than those of Vanuatu. Ramicrusta adjoulanensis possesses a well-developed epithallus with frequent cell fusions, secondary pit connections, and lacking hair bases or trichocytes, similar to Ramicrusta bonairensis. Ramicrusta adjoulanensis differs from other Ramicrusta species in having occasionally free margins and being attached by frequently produced, relatively long rhizoids (75–100 μm long). Ramicrusta asanitensis shares features with many other species, but the thickness of the crust (upwards of 2 mm thick), heavy calcification

Small tropical islands as hotspots of crustose calcifying red algal diversity and endemism
Introduction
In ecology, biodiversity has been the subject of extensive study, and has been shown to affect the stability, health, ecosystem processes, and overall performance of ecosystems (Naeem et al., 1994; Loreau et al., 2002; Tilman et al., 2006). Moreover, the implementation of new technologies (Mora et al., 2011) and the rapid changes that many ecosystems are experiencing (Hughes et al., 2003; Hughes et al., 2007) emphasize the need to further examine biodiversity worldwide, especially in the tropics (Paulay, 2003). Macroalgae are an integral component of tropical reefs and contribute significantly to the biodiversity of tropical reef ecosystems in the Pacific (Vroom, 2011). Of these, crustose calcifying red algae (CCRA) provide major ecological functions for tropical reefs. In this study, CCRA are comprised of the non-geniculate, calcified members of the Corallinophycidae and the Peyssonneliales. CCRA have long been considered as essential components
