AbstractMagnolia sinica, a Critically Endangered tree endemic to Yunnan, China, is one of the 20 plant species with extremely small populations approved by the Yunnan government for urgent rescue action before 2015. Information on the geographical distribution and population size of this species had not previously been reported, hindering effective conservation. We therefore carried out a survey of the literature and of herbarium specimens, followed by a detailed field survey and morphological measurements and observations of surviving individuals. We located 52 individuals in the wild, in eight localities. Two distinguishing morphological characters (tepal colour and tepal number) were revised based on observations of all remaining wild individuals that produced flowers and on one 30-year-old flowering plant in Kunming Botanical Garden. The survival rate of individuals propagated from seed for ex situ conservation at the Garden was 100% over 5 years; of 100 individuals transplanted to each of two reinforcement sites, 20 and 18, respectively, were alive after 6 years. We propose two groups of measures to protect M. sinica: (1) in situ conservation, population monitoring, and public engagement, and (2) ex situ conservation with reinforcement or reintroduction.

The Status

This study presents the status of ex situ and in situ conservation for the crop wild relatives of rice, potato, sweet potato, and finger millet in Brazil, and the subsequent germplasm collection expeditions. This research is part of a global initiative entitled “Adapting Agriculture to Climate Change: Collecting, Protecting, and Preparing Crop Wild Relatives” supported by the Global Crop Diversity Trust. Species of the primary, secondary, and tertiary gene pools with occurrences reported in Brazil were included: Oryza alta Swallen, O. grandiglumis (Döll) Prod., O. latifolia Desv., O. glumaepatula Steud., Eleusine tristachya (Lam.) Lam., E. indica (L.) Gaertn., Solanum commersonii Dunal, S. chacoense Bitter, Ipomoea grandifolia (Dammer) O’Donell, I. ramosissima (Poir.) Choisy, I. tiliacea (Willd.) Choisy, I. triloba L., and I. cynanchifolia Meisn. The status of the ex situ and in situ conservation of each taxon was assessed using the gap analysis methodology, and the results were used to plan 16 germplasm collection expeditions. Seeds of the collected material were evaluated for viability, and the protocols for seed germination and cryopreservation were tested. The final conservation score, resulting from the gap analysis and including the average of the ex situ and in situ scores, resulted in a classification of medium priority of conservation for all the species, with the exception of I. grandifolia (high priority). The total accessions collected (174) almost doubled the total accessions of these crop wild relatives incorporated in Embrapa’s ex situ conservation system prior to 2015. In addition, accessions for practically absent species were collected for the ex situ conservation system, such as Ipomoea species, Eleusine indica, and Solanum chacoense. The methods used for dormancy breaking and low temperature conservation for the Oryza, Eleusine, and Ipomoea species were promising for the incorporation of accessions in the respective gene banks. The results show the importance of efforts to collect and conserve ex situ crop wild relatives in Brazil based on previous gap analysis. The complementarity with the in situ strategy also appears to be very promising in the country.

In this study, we observed the flowering phenology, breeding system, pollination and seed germination of four species of Calligonum (C. calliphysa, C. rubicundum, C. densum and C. ebinuricum) in the Turpan Eremophytes Botanic Garden, China. Our results showed that the species had overlapping flowering phenologies and were pollinated by similar pollination agents. Their breeding systems were self-compatible, and with signs of outbreeding, but not of hybridization with each other; the main isolation mechanism was post-zygotic isolation and they also had high seed germination rates. Therefore, they are suited to ex situ conservation in the Turpan Eremophytes Botanic Garden, and can supply sufficient seeds for renewal populations and the conservation of germplasm resources. Furthermore, these results provide theoretical support for the construction of a national germplasm resource garden of Calligonum, and for the introduction to the garden of other eremophyteplants and their conservation.

A New Species

Lactarius sect. Deliciosi is a group of ectomycorrhizal mushrooms showing high host specificity with trees of Pinaceae and more rarely Fagales. A new species of this section, L. guangdongensis, is described from South China. This new species has the smallest basidiocarps (pileus 1–3 cm) in the section. The pure orange basidiocarps with faint greenish discoloration are similar to those of Abies-associated L. abieticola and L. laeticolor and Pinus-associated L. vividus. The subdistant lamellae and absence of pleuromacrocystidia can be used as valid characters for this species. It grows with Chinese national protected plant Pinus kwangtungensis and might be one of the very few species that form symbiosis with five-needle pines. Phylogenetic analyses of the ITS region and glyceraldehyde-3-phosphate dehydrogenase gene (gpd) show that L. guangdongensis clearly diversified from its relatives and look-alikes and probably represents an early diverging lineage in the section. Molecular and morphological characters provided in this study will be useful for in situ and ex situ conservation of P. kwangtungensis in the future.

AbstractThe tropical island nation of Sri Lanka is a biodiversity hotspot with a high diversity and endemism of amphibians. The endemic, stream-dwelling Kandian torrent toadAdenomus kandianusis Critically Endangered and was considered to be extinct until its rediscovery in 2012. The species is now known from two localities in tropical montane forests. We conducted a 4-year study using transect surveys and opportunistic excursions to assess habitat associations, demographics and abundance ofA. kandianusin and around Pidurutalagala Conservation Forest. We recorded a mean of 44.25 post-metamorphs per year, with a density of < 1 individual per 100 m2, with occurrence within a narrow extent (c. 0.005 km2) of the stream channel. Behaviour and microhabitat selection varied depending on sex and stage of maturity. The species preferred moderately sized montane streams with rocky substrates and woody debris, colder temperatures, and closed-canopy, intact riparian forests. We noted size-based reversed sexual dimorphism and a strong ontogenetic relationship between snout–vent length and body weight. Anthropogenic activities such as intensive crop farming deterred the species; proximity to croplands had a negative influence on abundance. We recommend re-delineation of the boundary of Pidurutalagala Conservation Forest to incorporate the toad's habitat into the core of the reserve and thus limit the impacts of human activities. Conservation and management actions such as ex-situ breeding, population monitoring, and restoration of degraded habitats could also contribute towards the persistence of this toad. Our findings provide useful insights into ecological research on and conservation of range-restricted aquatic amphibians.

Sambas Botanical Garden is an ex-situ conservation area, in its management there is the term Vak, which is a small management area with care and supervision that is more focused on the inside plants, Bellucia pentamera in the management of Vak is very limited and cut down, but actually Bellucia pentamera is forest plant which has the criteria of providing fruit almost all year long and is widely used by most wildlife. The study aims to record species of aves and diurnal mammals that use Bellucia pentamera as a source of feed for wild animals in the Sambas Botanical Gardens. The research was carried out in the management area and secondary forest, each represented by three growing places, namely hills, foothills and riparians. The study was conducted in July-August with a survey method by observing direct observation at the point of tangkalak guava stands with repetitions three times. The results showed that seven types of aves were found, namely Chloropsis sonnerati, Dicaeum trigonostigma, Dicaeum trochileum, Pycnonotus goiavie, Chloropsis cochinchinensis, Zosterops palpebrosus, and Arachnothera crassirostris, There are four types of mammals found, namely Macaca fascicularis, Sundasciurus lowii, Callosciurus prevostii, and Callosciurus orestes.Keywords: Aves, Bellucia pentamera, Feed, Mammals

A spontaneous intergeneric hybrid of Sorbus and Cotoneaster – Pozdnyakov’s sorbocotoneaster (× Sorbocotoneaster pozdnjakovii Pojark.) is an endemic of the South Yakutia. It is known from the river basin Aldan in the areafrom the city of Tommot to the mouth of the river Uchura and on the Aldan-Amga interfluve. It grows in the undergrowthof sparse pine and larch forests on stony-gravelly limestone slopes. It was first found by L. K. Pozdnyakov, a forester,an employee of the Institute of Forest of the Siberian Branch of the USSR Academy of Sciences, on September 9, 1950,when examining forests on permafrost in Yakutia: “in the area of the confluence of the Aya-Sullalah river into Aldan,105–110 km down the Aldan from Tommot” (from the letter of L. K. Pozdnyakov to A. T. Grevtsova, 1982). The article provides data on the origin of the specimens × Sorbocotoneasters, the morphological description of leaves, flowers, fruits,the peculiarities of growth and development in conditions of Kiev, micrographs of pollen grains, micrographs of theendocarp of fruits of three forms, the beginning of the destruction of the scutellum and hypostyle from the ventral side ina hybrid of the third form. Botanical Garden named after acad. A. V. Fomin of the Taras Shevchenko National Universityof Kiev is the only ex situ conservation site in Eastern Europe of the unique Yakut hybrid × Sorbocotoneaster pozdnjakoviiwith leaves of the 1st, 2nd and 3rd forms.
