Applying the IUCN Red List criteria to small-sized plants on oceanic islands: conservation implications for threatened bryophytes in the Canary Islands

Two new micro-endemic species of Eriocaulaceae are described from the Campos Rupestres of Serra Nova State Park, a conservation unit located in the Espinhaço Range in northern Minas Gerais state, Brazil. Herein we provide descriptions, illustrations, photographs and maps, together with notes on morphology, distribution, phenology, taxonomy, and conservation. Paepalanthus ferrugineus is distinguished mainly by the reddish-brown involucral bracts, surpassing the floral disc, with the apex attenuate and tufted adaxially, tufted sepals and hairy petals. Syngonanthus polyaxis is easily differentiated by the inflorescence architecture with three morphologically distinct axial parts. Both species are considered Critically Endangered according to the IUCN Red List criteria.

The new species Chiococcagrandiflora Lorence & T.Van Devender from Sinaloa and Sonora, Mexico differs from its congeners by its larger, showy white flowers in compact cymes of 3–9, and infundibuliform corollas 16–20 mm long with tubes 13–17 mm long and lobes 3–3.5 mm long. Its distribution, habitat, and relationships are outlined. The conservation status for this species is estimated to be Endangered (EN) based on IUCN Red List Criteria.

A New Species

A new species of indotyphlid caecilian amphibian, Hypogeophis montanus sp. nov., is described based on a series of specimens from the Seychelles island of Mahé, collected from two localities in 2013 and 2015. The new species most closely resembles the Seychelles (Mahé) endemic H. brevis in being short (maximum known total length in life ca. 110 mm) and long snouted, but differs by having more vertebrae, a relatively smaller head, and substantially distinct mitochondrial and nuclear gene sequences. Hypogeophis montanus sp. nov. is known from higher elevations (718–731 m) than H. brevis (ca. 350–650 m), and its elevationally restricted distribution on a single small island likely renders it threatened under IUCN Red List criteria. Hypogeophis montanus sp. nov. is the third species of small and long-snouted caecilian reported from the Seychelles. Along with H. brevis and H. pti, H. montanus sp. nov. is among the smallest known species of caecilian and possibly has the smallest global distribution.

A New Species

Begonia tinuyopensis is described and illustrated as a new species from Zamboanga del Norte, Philippines. This new species resembles B. mearnsii by having a decumbent stem, scattered hairs over the entire plant, terminal inflorescence bearing 2 staminate tepals and 5 pistillate tepals. However, Begonia tinuyopensis is distinct by having sparse pilose (vs. matted with long brown hairs) stems, ovate (vs. suborbicular to subreniform) leaves and glabrous (vs. densely pubescent) ovary. We assign B. tinuyopensis as Endangered (EN) following IUCN Red List Criteria.

We describe a new species of Ptychadena from Mutinondo Wilderness in northern Zambia. It has rupicolous tadpoles that develop in a film of water. The species is distinguished on morphology, advertisement call and DNA sequences from other grass frogs and was found to be most closely related to P. broadleyi. It has no contrasting longitudinal bands on the posterior thigh, the foot is longer than half SVL, it has no light triangle on the snout, three phalanges of the fourth toe free of web and the snout has no skin folds. The species should be considered Near Threatened in terms of the IUCN Red List criteria given its limited extent of occurrence and population size.

Iucn Red List Criteria

The Action Plan for Australian Birds 2010 is the third in a series of action plans that have been produced at the start of each decade. The book analyses the International Union for Conservation of Nature (IUCN) status of all the species and subspecies of Australia's birds, including those of the offshore territories. For each bird the size and trend in their population and distribution has been analysed using the latest iteration of IUCN Red List Criteria to determine their risk of extinction. The book also provides an account of all those species and subspecies that are or are likely to be extinct. The result is the most authoritative account yet of the status of Australia's birds. In this completely revised edition each account covers not only the 2010 status but provides a retrospective assessment of the status in 1990 and 2000 based on current knowledge, taxonomic revisions and changes to the IUCN criteria, and then reasons why the status of some taxa has changed over the last two decades. Maps have been created specifically for the Action Plan based on vetted data drawn from the records of Birds Australia, its members and its partners in many government departments. This is not a book of lost causes. It is a call for action to keep the extraordinary biodiversity we have inherited and pass the legacy to our children. 2012 Whitley Award Commendation for Zoological Resource.

New Distribution

A new fern species, Polystichum alluvium, a member of P. subg. Haplopolystichum (Dryopteridaceae), is described from Guizhou Province in Southwest China. Polystichum alluvium is similar to P. lanceolatum in having small habit and subcoriaceous pinnae, but the former has oblanceolate laminae with basal pinnae strongly contracted toward lamina base, deltoid-ovate and sessile pinnae, and very short spinules on acroscopic pinna margins or no spinules, while the latter has lanceolate laminae with basal pinnae not contracted toward lamina base, oblong and petiolate pinnae, and long spinules on acroscopic pinna margins. Polystichum alluvium was found from the alluvial bottom of a karst cave at an elevation of 1410 m with humid and shady conditions and is currently known from one population with ca. 50 plants in western Guizhou. It is classified as Critically Endangered (CR) following IUCN Red List criteria. We also expanded the distribution of P. leveillei to southern-central Guizhou based on our new collections.
