Abstract:

Abstract Significant increase of biological stability, timber volume, and economic value of forests is impossible without refinement and improvement of the organization, and implementation of forest seed production on a genetic and breeding basis. It is possible to solve this task by creating and efficiently functioning in situ and ex situ facilities. In Ukraine, the basic principles of plus selection are envisaged, which include the selection and testing progeny of plus trees. The total number of progeny tests in Ukraine is 106 plots, in which 1,079 genotypes of plus trees are presented. Taki

The high conservation status of ironwood (Eusideroxylon zwageri Teijsm & Binn.) causes conservation efforts need to be carried out immediately. Balitek KSDA has carried out ulin conservation efforts by building ulin ex-situ conservation plots in the Samboja KHDTK with seeds from the Sungai Wain, Sangatta and Berau. This study was conducted to evaluate the variation of ironwood plant growth from these three provenances in the Samboja KHDTK. The results showed that the average survival rate of ironwood plant was 79.12% and there were no differences in the three provenances. Plants from Sanga

Abstract:

From the genus Ulmus, the naturally spread species in Bulgaria are Ulmus minor, U. laevis, and U. glabra. The main reason for the decreasing of the number and density of the elm populations in Bulgaria are the epyphytonic expressions of the Dutch elm disease (DED) in the 1920s and 1970s, after which the representatives of genus Ulmus today occur predominantly as solitaire trees, biogroups and rarely form stands. In connection with the preservation of the genepool of the elms after the in situ method, an inventory of their genetic resources in North Bulgaria has started in 2002. To study the va

Native, endemic, and threatened flora species in a swamp forest in Tagum City, Philippines: Implications for species and habitat conservation. Biodiversitas 26: 1189-1201. Endemic and threatened plants are among the most susceptible species, and are considered the most effective surrogates for identifying and evaluating conservation priority areas. This study aimed to provide critical information regarding native, endemic, and threatened flora species within the swampy beach forest ecosystem of Hijo, Tagum City, Davao Del Nort

Biodiversitas 20: 3189-3198. The study described the communities of woody plants in a semi-evergreen tropical forest dominated by endemic Philippine teak (Tectona philippinensis Benth. & Hook. f, Lamiaceae) and determined the local environmental factors affecting the distribution of dominant woody species across the Philippine teak forest (PTF) landscape. The Philippine teak is a Critically Endangered species acco

Abstract:

In response to declining coral populations worldwide, conservation groups are increasingly applying restoration strategies to bolster abundance and diversity, including sexual propagation of corals. Collection and fertilization of coral gametes as well as larval rearing and settlement have been successful. However, post‐settlement stages remain a bottleneck (80–100% mortality), which makes this technique costly to implement at scale. To address this challenge, we compared the survival and colony size of three sexually propagated Caribbean coral species, Diploria labyrinthiformis, Pseudodiplori

Abstract:

AbstractSacred sites like monasteries harbour a higher diversity of flora and fauna than nearby unprotected areas and sometimes even higher than protected areas. However, anthropogenic disturbance puts woodlands in these monasteries and churches under significant threat. To study the floristic composition and forest degradation of Waldiba monastery woodland in Tigrai, Ethiopia, 30 plots were established along transect lines. We recorded 39 native woody species (33 trees, 5 shrubs and 1 liana) belonging to 19 families. The woodland had a Shannon diversity index of 3.10, Simpson similarity index

Abstract:

Climate change is impacting the sustainability of indigenous tree species. However, the impacts of climate change on African olive tree (Olea europaea subspecies Cuspidata) are less‐explored. This study, conducted in Tigray, northern Ethiopia, aims to determine the impacts of climate change on the current and future distributions of the species. A total of 225 presence points and abundance of O. europaea within 20 m × 20 m plots at each location were collected. Additional input variables, such as the 19 bioclimatic variables, 3 topographic variables, and Pedologic data, were used. Maxent softw

IntroductionSaussurea costus, an important critically endangered medicinal herb native to the Himalayan region, is commonly used in various ailments, viz. asthma, ulcer, inflammation, and stomach problems. In the international market, the dry roots and essential oil of S. costus has become an important drug. The lack of appropriate fertilizer dose recommendations is one of the limiting factors for its ex-situ conservation and large-scale cultivation, as plant nutrition is vital in determining crop growth and productivity.

Abstract:

AbstractPlants living at the edge of their range boundary tend to suffer an overall decline in their fitness, including growth and reproduction. However, the reproductive performance of plants in artificially expanded habitats is rarely investigated, although this type of study would provide a better understanding of range limitations and improved conservation of ex situ plants. In the current study, we transplanted a narrowly dispersed species of Gentiana officinalis H.
