The incidence of Tomato brown rugose fruit virus (ToBRFV) and biological and molecular characterization of the Palestinian isolates of ToBRFV are described in this study. Symptomatic leaf samples obtained from Solanum lycopersicum L. (tomatoes) and Nicotiana tabacum L. (cultivated tobacco) plants were tested for tobamoviruses infection by reverse transcription polymerase chain reaction. Tomato leaf samples collected from Tulkarm and Qalqilia are infected with ToBRFV-PAL with an infection rate of 76% and 72.5%, respectively. Leaf samples collected from Jenin and Nablus were found to be mixed infected with ToBRFV-PAL and Tobacco mosaic virus (TMV) (100%). Sequence analysis of the ToBRFV-PAL genome showed that the net average nucleotide divergence between ToBRFV/F48-PAL strain and the Israeli and Turkish strains was 0.0026398±0.0006638 (±standard error of mean), while it was 0.0033066±0.0007433 between ToBRFV/F42-PAL and these two isolates. In the phylogenetic tree constructed with the complete genomic sequence, all the ToBRFV isolates were clustered together and formed a sister branch with the TMV. The sequenced Palestinian isolates of ToBRFV-PAL shared the highest nucleotide identity with the Israeli ToBRFV isolate suggesting that the virus was introduced to Palestine from Israel. The findings of this study enhance our understanding of the biological and molecular characteristics of ToBRFV which would help in the management of the disease.

The US National Science Foundation's National Ecological Observatory Network (NEON) is a continental-scale program intended to provide open data, samples, and infrastructure to understand changing ecosystems for a period of 30 years. NEON collects co-located measurements of drivers of environmental change and biological responses, using standardized methods at 81 field sites to systematically sample variability and trends to enable inferences at regional to continental scales. Alongside key atmospheric and environmental variables, NEON measures the biodiversity of many taxa, including microbes, plants, and animals, and collects samples from these organisms for long-term archiving and research use. Here we review the composition and use of NEON resources to date as a whole and specific to biodiversity as an exemplar of the potential of national research infrastructure to contribute to globally relevant outcomes. Since NEON initiated full operations in 2019, NEON has produced, on average, 1.4 M records and over 32 TB of data per year across more than 180 data products, with 85 products that include taxonomic or other organismal information relevant to biodiversity science. NEON has also collected and curated more than 503,000 samples and specimens spanning all taxonomic domains of life, with up to 100,000 more to be added annually. Various metrics of use, including web portal visitation, data download and sample use requests, and scientific publications, reveal substantial interest from the global community in NEON. More than 47,000 unique IP addresses from around the world visit NEON's web portals each month, requesting on average 1.8 TB of data, and over 200 researchers have engaged in sample use requests from the NEON Biorepository. Through its many global partnerships, particularly with the Global Biodiversity Information Facility, NEON resources have been used in more than 900 scientific publications to date, with many using biodiversity data and samples. These outcomes demonstrate that the data and samples provided by NEON, situated in a broader network of national research infrastructures, are critical to scientists, conservation practitioners, and policy makers. They enable effective approaches to meeting global targets, such as those captured in the Kunming-Montreal Global Biodiversity Framework.

1. Hanoi city was built up on the wetland landscape of the Red River delta therefore it has a network of many lakes and rivers. 2. The aquatic biodiversity (Macrophytes, Invertebrates, Fishes, Vertebrates) of the 6 main lakes (Ho Tay, Hoan Kiem, Bay Mau, Giang Vo, Dong Da, Thanh Nhan) are rich and diverse. It represents the patterns of Red River delta one's. Many rare and endangered species are found in these lakes Particularly a giant freshwater turtle species in Hoan Kiem lake. 3. All of these lakes are more or less polluted. Their environments are seriously degrading both in water quality and aquatic biodiversity. 4. Based on socio-economical and cultural role of these lakes of Hanoi city, it is very necessary to preserve and to restore their environments and aquatic biodiversity: water Pollution control, landscape planning, making roads around the lakes and erosion control for their banks, legislation measures, rational exploitation of aquatic biodiversity, restoration the artificial wetlands with macrophytes.

Tofieldia ulleungensis, a new species of the genus Tofieldia from the Nari Basin on Ulleungdo Island, Korea, is described and illustrated. The new species is similar to T. yoshiiana var. koreana in terms of the plant height and in that it has having a long raceme, whitish tepals, and whitish stigma, but can be readily distinguished from the latter by the presence of 1-2 linear cauline leaves, a slightly bent leaf apex, basal leaves which are twice as wide, a shorter pedicel, a revolute style, and crescent-shaped seeds.

The Ministry of Environment of South Korea has launched its plan to establish the National Ecological Institute. An International Symposium and Workshop was held at Ewha Womans University in Seoul on Thursday, 30 September 2010, to strengthen international cooperation, networking and partnerships for the conservation of biodiversity. This symposium was attended by experts of many major institutions for biodiversity conservation from South Korea and overseas. At the symposium and workshop preceded by a keynote speech by the renowned primatologist and conservation biologist Jane Goodall the participants discussed a wide range of topics including "biodiversity conservation: in situ and ex situ approaches", "conservation of species diversity and ecosystem management", and "international cooperation for biodiversity conservation and research". As a basis for future discussions, this article summarizes how the National Ecological Institute might contribute most effectively to public life and environmental management in South Korea and worldwide. It addresses the following issues: governance and funding, synergies within Korea, participation in international networks, external advice, a broad view of ecological issues, research agenda, building on identity, public outreach, and training the next generation of scientists.

The materials that are involved in urban landscaping include plants and the associated animals, soil, water, and other environmental elements. And biodiversity is the substantial base for human beings. The conservation of biodiversity is of great importance in the sustainable development of the society and should not be neglected in the development of sustainable urban landscape. The conservation of biodiversity should be included in the urban landscape planning. The conservation of biodiversity should be emphasized in the construction of urban green space. Every possible opportunity should be used to conserve the species diversity, genetic diversity and ecological diversity. The assessment of biodiversity conservation should be introduced into modern landscape planning.

The pulmonate gastropod Ellobium chinense (Pfeiffer, 1864) is an endangered marine species along the South Korean coasts due to habitat destruction and population declines. We sequenced the cytochrome c oxidase subunit 1 (COI) of 25 E. chinense specimens collected from five coastal sites in South Korea, and identified 16 unique haplotypes. The maximum intraspecific variation among individuals was 1.6%, while interspecific differences from another ellobiid species, Auriculastra duplicata (Pfeiffer, 1854), ranged from 21.9 to 23.0%. Our barcoding data will be useful to elucidate the phylogenetic relationships among pulmonate gastropods and infer the population genetic structure of E. chinense.
