Abstract: Ramphastidae is Family of secondary cavity-nesting birds that is endemic to the Neotropical region. Here we provide a comprehensive literature review of nest measurements, and new information on characteristics of the nest cavity, parental nest attendance, incubation and nestling period of the Red-breasted Toucan, Ramphastos dicolorus. We also add information on the origin of the seeds found inside toucan nests and propose a potential function for them. Eight nests were studied in three cavities during six breeding seasons at Parque Estadual das Fontes do Ipiranga, São Paulo, and at a private allotment in Ibiúna, southeastern Brazil. The reproductive activities of the birds were observed from September to February. In one cavity, we found the first record of a Meliponini bee hive (Scaptotrigona bipunctata) co-existing with a toucan nest. At the beginning of the nesting season, the parents regurgitate seeds on the floor of the cavity, covering it with them. This preparation plays a role in nest sanitation, once the seeds act as a substrate for the feces facilitating the process of carrying them off the nest by the female. The incubation and nestling periods lasted 17.2 ± 1.2 and 43 ± 5.4 days, respectively, and both parents shared egg incubation, nestling, brooding and provisioning, but only the female performed nest sanitation. This differs from published observations on other species of the group, suggesting that the participation of each sex in nest attendance may not be the same for all ramphastids. Additionally, our observations suggest that selecting anthropic locations for nesting can negatively influence toucan nest success.

First Time

Two species of axiid shrimp are reported from sublittoral to upper bathyal waters around the Ogasawara Islands, Japan. The first, Bouvieraxius keiensis Sakai, 1992, is recorded from Japanese waters for the first time, although it is known widely from the southwestern Pacific to western Indian Ocean. Taxonomic problems of this taxon are pointed out. The second, Manaxius aurantiaca n. sp., is described based on a single female specimen from the Kaikata Seamount (at a depth of 299–335 m). It has rounded pleura of the pleomeres 2–5, and is notable in the lack of spines on the upper margin of the cheliped palms. In this regard, the new species closely resembles M. iro Poore, 2020. Differentiating characters between M. aurantiaca n. sp. and M. iro are discussed.

Molecular Phylogenetic

Molecular phylogenetic analyses, morphological observations, and nomenclatural studies were carried out to investigate the taxonomic status of Portulaca boninensis, endemic species from the Bonin (Ogasawara) Islands (Japan). The results addressed controversy between the widely naturalized P. boninensis and P. pilosa, indicating that they are phylogenetically and morphologically distinct. Furthermore, P. boninensis was showed to be conspecific to P. psammotropha which is until now recorded in southern China, Taiwan, and the northern Philippines, but not in the Ryukyus. The name of P. psammotropha was lectotypified on a specimen preserved at K. Based on phylogeography, P. psammotropha likely migrated to the Oceanic Bonin Islands oversea by sea-current dispersal or by exo- and/or end ozoochory through migratory birds without passing through Ryukyus.

Abstract New taxonomic and distributional data are provided for three eastern Asian species of Calamagrostis (Poaceae, Agrostidinae) in Vietnam: C. abnormis (Hook. f.) Shukla, C. extremiorientalis (Tzvel.) Prob. and C. tripilifera Hook. f. The new national record of C. extremiorientalis is reported here for Vietnam, where it was previously misidentified as C. elatior (Griseb.) A. Camus or Deyeuxia petelotii Hitchc. (= C. abnormis). The presence of C. tripilifera and C. abnormis in Vietnam is confirmed. Additional new provincial records of C. extremiorientalis from Japan’s Bonin Islands (also known as the Ogasawara Islands) and C. tripilifera from Daba Mountains in the northern Chongqing Municipality (Central China) are reported here. A key for identification of Calamagrostis species in Vietnam, nomenclatural data and information about geographical, altitudinal and habitat distributions are provided. Maps showing their complete distribution in eastern Asia are presented.
