Species Specific

This study serves as the first generation research on the rich yet not poorly known ferns and lycophyte species of the Mount Timolan Protected Landscape (MTPL). A total of 151 species from 62 genera and 24 families were recorded from December 2019-May 2019. Overall, the species of MTPL respectively holds 14%, 40% and 71% of the recorded total species, genera and families of ferns and lycophytes in the Philippines. The most represented families in terms of the number of genera is Polypodiaceae (10 spp.), whereas, the most represented genera in terms of the number of species were Selaginella (11 spp.). The results of the study showed that Mount Timolan Protected Landscape harbours number of some endemic species (17 spp.), critically endangered species (1 spp.), endangered species (3 spp.), vulnerable species (5 spp.), threatened, non-native species and economically important species (25 spp.). Based on conservation and ecological status of assessed ferns and lycophyte species, it is likely to strongly suggest to set species-specific conservation management strategy to protect the threatened species. However, additional studies and thorough field explorations should also be done to conduct a re-inventory on the pteridophyte species in order to arrive a more scientific results to establish a real profile of the ferns and lycophyte species of Mount Timolan Protected Landscape.

Quezon Protected Landscape (QPL) is a tropical rainforest situated at the southern Sierra Madre mountain range. However, it is subjected to anthropogenic pressure that poses threats to its flora and fauna. This study was conducted to describe the plant diversity, assess their ecological and conservation status, and to identify current anthropogenic threats in various vegetation types in QPL. Vegetation assessment was done using quadrat method established at different land use types wherein ninety 10×10 m nested plots were used for trees, 5×5 m subplots were used for herbs and shrubs, and 1×1 m subplots were used for grasses. The study documented a total of 328 species belonging to 84 families and 208 genera with 2,737 individuals. Species diversity is high as revealed by the values obtained from species diversity (H’) and species evenness (J’) indexes. Out of 172 tree species identified, the most important species are: Parashorea malaanonan (Blanco) Merr. in the regenerating and lowland evergreen dipterocarp forest; Diospyros pyrrhocarpa Miq. in the karst forest; Leucaena leucocephala (Lam.) de Wit in the secondary forest; and Cocos nucifera L. in the agroforest. Assessment of ecological status showed that out of 328 species, 213 (64.94%) are native, wherein 65 (19.8%) are endemic, and 115 (35.06%) are introduced. Forty-five species (13.72%) are threatened in which 25 of those are endemic in the Philippines. Overall, QPL has a wide array of plant species and threats such as the illegal extraction of natural resources, encroachment, cleanliness and presence of invasive alien species. So, it is recommended that protection and awareness campaign should be done for conservation and sustainability.

Species Specific

The increasing use of exotic and hybrid poplar species in forestry and the lack of genetic barriers between most poplar species may present a risk to the genetic integrity of native poplar species. To monitor any spontaneous hybridization and (or) introgression from exotics into native species, it is essential to have a system for the quick and reliable identification of species. We developed a set of single nucleotide polymorphism (SNP) markers that allows the distinction between five commercially important species of poplar ( Populus balsamifera L., Populus deltoides Marsh., Populus trichocarpa Toor. ex Gray, Populus nigra L., and Populus maximowiczii Henry) and their hybrids. Six genomic regions spanning 6.1 kb were screened at the DNA sequence level to search for discriminating SNPs among the five species. A total of 245 SNPs and indels were found, 86 of which were species specific. A subset of 12 species-specific SNPs was chosen for use with high-throughput SNPstream technology. In addition, 32 species-specific SNPs and indels were found that can be assayed using restriction enzymes. Application of the developed markers to a set of hybrid clones showed that the markers are not only useful for monitoring introgression but also for the verification of breeding material.

Critically Endangered Species

Abstract Queimada Grande (QGI) is a small, legally protected island off the southeastern coast of Brazil that harbors two endemic and critically endangered herpetofauna species: the Golden Lancehead viper (Bothrops insularis) and a hylid frog (Scinax peixotoi); its vegetation, however, has been little studied. We integrated remote sensing and phytosociology of the Atlantic Forest on QGI to characterize the habitat of those two species and support their in situ conservation. QGI retains a mosaic of Atlantic Forest, rock outcrop and anthropogenic vegetation, including invasive alien species, and bare rock surfaces. Mature Atlantic Forest, the preferential habitat of B. insularis and S. peixotoi, currently covers ~28 ha (~50%) of QGI and shows very low tree richness and an oligarchic structure. The most important species are Guapira opposita, Rudgea minor and Aspidosperma australe. Anthropogenic formations cover ~9% of the island and do not seem to have expanded in recent years. Based on local conditions, we recommend permanent monitoring of QGI and the use of local tree species in projects to restore the habitat of those two endangered species.

New Distribution

Platycerium grande (Fee) Kunze is an endemic, Critically Endangered species of fern in the Philippines. The known distribution of this species remains limited at present and its population is threatened by various anthropogenic threats especially for ornamental collection.  In our recent survey, we found high abundance of this species in Central Mindanao, southern Philippines.  It can be distinguished from other species belonging to the genus Platycerium through its frond’s vegetative leaf which is symmetrical with two equally long main lobe.  Based on literatures, the known distribution range extend from Zambaonga, Lanao, and Davao (Mt. Apo); and our recent records extends the known distribution of this species in Kalamansig, Sultan Kudarat and South Upi, Maguindanao suggesting this species may still be around in other areas within the known range, however, the species may remain narrowly distributed as multiple threats to this species continue to persist.

Abstract: The Resplendent Shrub Frog, Raorchestes resplendens Biju, Shouche, Dubois, Dutta, & Bossuyt, 2010 is a Critically Endangered species endemic to the Western Ghats and was considered to be restricted to a three-square kilometer patch atop Anamudi summit.  In this study, we report 36 new locations of the species from the Anamalai massif of the southern Western Ghats.  Niche-based prediction modelling suggests that the species is restricted to Anamalai massif.  The call description of this frog is also provided for the first time. The preferred microhabitat of the frog is Chrysopogon grass clumps in the marshy/swampy montane grassland ecosystem. Restricted to a small area with controlled burning management practiced in its habitat, R. resplendens needs immediate attention.

Chapter 7 focuses on the upbringing of the second generation of the Russian bourgeoisie. As the first generation of wealthy Russians grows older, they are becoming more aware of their own mortality and are preparing to hand over their wealth to the next generation. It seems that rich Russians are yet to find a convincing narrative to justify their children’s legitimate entitlement to wealth that does not contradict their own everyday ideology of being self-made. Nevertheless, a two-pronged approach is emerging. First, in line with the shift toward new modesty, children are being encouraged to cultivate a habitus of privilege, as Sherman suggests in the case with wealthy US Americans, which makes them appear morally worthy in an environment marked by extreme inequality. Second, via their philanthropy the rich are supporting institutions and scholars in an effort to strengthen a dynamic capitalist environment in which privileged status is respected.

Population Sizes

The increasing demand for tropical timber from natural forests has reduced the population sizes of native species such as Cedrela spp. because of their high economic value. To prevent the decline of population sizes of the species, all Cedrela species have been incorporated into Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). The study presents information about the modeled distribution of the genus Cedrela in Peru that aims to identify potential habitat distribution of the genus, its availability in areas protected by national service of protected areas, and highlighted some areas because of their conservation relevance and the potential need for restoration. We modeled the distribution of the genus Cedrela in Peru using 947 occurrence records that included 10 species (C. odorata, C. montana, C. fissilis, C. longipetiolulata, C. angustifolia, C. nebulosa, C. kuelapensis, C. saltensis, C. weberbaueri, and C. molinensis). We aim to identify areas environmentally suitable for the occurrence of Cedrela that are legally protected by the National Service of Protected Areas (PAs) and those that are ideal for research and restoration projects. We used various environmental variables (19 bioclimatic variables, 3 topographic factors, 9 edaphic factors, solar radiation, and relative humidity) and the maximum entropy model (MaxEnt) to predict the probability of occurrence. We observed that 6.7% (86,916.2 km2) of Peru presents a high distribution probability of occurrence of Cedrela, distributed in 17 departments, with 4.4% (10,171.03 km2) of the area protected by PAs mainly under the category of protection forests. Another 11.65% (21,345.16 km2) of distribution covers areas highly prone to degradation, distributed mainly in the departments Ucayali, Loreto, and Madre de Dios, and needs immediate attention for its protection and restoration. We believe that the study will contribute significantly to conserve Cedrela and other endangered species, as well as to promote the sustainable use and management of timber species as a whole.
