Parasitic plants proliferation globally is daunting and a threat to our ecosystems. In this study we explore holoparasites with limitation to dodders (Cuscuta spp. & Cassytha filiformis). An experiment was performed to ascertain anatomical and morphological characteristics of dodder capsule and its stem. We present dodder infestation stages, development phases and close observable internal and external microscopic features. A distinct haustorium trait of dodders is shown by micrographs. The study finds that dodder seeds possess high ecological dispersal character with vast adaptability through morphological analysis. This ramifies their ecological phenotypic plasticity. Externally, dodder stems attack the host phloem through haustoria that suck nutrients from the sap weakening it.

Continuing the series of articles that promote the implications of thematic philately about protected natural areas, we stopped this time, on the Piatra Craiului National Park. As an area of national interest, the Piatra Craiului area has also been immortalized on various post-philatelic effects. From the multitude of philatelic pieces (postage stamps, envelopes on the first day of the show - FDCs, illustrated postcards, occasional envelopes, etc.) that were identified, the reproduction was chosen only of those who contributed to the promotion of tourism potential. From landscapes to species of flora and fauna, of scientific interest and environmental protection, the pieces analyzed come to certify the idea that thematic philately is more than an ambassador of the intrinsic values of an area. In fact, by appealing to philatelic effects, the entire community had to gain in terms of the fact that tourists, mostly from abroad, had already provided access to tourist information and more.

People repeatedly confronted by natural catastrophe in almost every year such as drought and flood in the lower Teesta Basin area. After the construction of two barrages in Gozaldoba and Dalia on Teesta River drought and flood occurs almost every year. Intensity and frequency of these calamities are also increasing in an alarming rate, which caused serious damage to livelihoods and economy of this area. The objective of this paper is to find out the drought and flood induced vulnerability in the study area through Strength Weakness Opportunities Threat (SWOT) analysis. By this we can summarize the current state of a space and helping to devise a plan for the future, one that employs the existing strengths, redresses existing weaknesses, exploits opportunities and defends against threats. The study is conducted in Charkharibari village of Tepakharibari union of Dimla upazilla in Nilphamary district and Jigabari village of Tepamadhupur union of Kaunia upazilla in Rangpur district, taking the locational advantage, flood and drought proneness, topographic nature and population diversity under consideration. The study population is finite and sample size was determined by using Kothari’s formula. Sample size for Charkharibari and Jigabari is 200 and 85 respectively; samples were drawn through Simple Random Sampling (SRS) procedure. The relevant data and information used in this study have been collected from both primary and secondary sources. Primary data has been collected through a questionnaire survey and couple of Focus Group Discussions (FGD’s) with a view to collect quantitative as well as qualitative data. Results from Strength Weakness Opportunities Threat (SWOT) analysis shows that, between the two villages severity of drought and flood is higher in Charkharibari village. After comparing the strengths Jigabari is ahead; comparing weakness, opportunities and threat Charkharibari is ahead. Based on the analysis and the findings, it is evident that in terms of vulnerability Charkharibari is more vulnerable than Jigabari. But there are more opportunities for Charkharibari than Jigabari. However, it is evident that proper dissemination of information regarding early warning and assistance from government as well as non-government organizations can significantly improve the coping capacity of people.

One of the most beautiful countries in Europe, Romania, offers many travel experiences that are just waiting to be discovered. The words that best describe the essence of Romania are authentic, natural, and cultural, being a country rich in history, art, and natural beauty. As a part of Europe, Romania has often earned its reputation as a country with special cultural and spiritual values. Most often, however, it has been noted in terms of people who have sanctified the places, in terms of places and monuments that delight our eyes, but especially in terms of biodiversity in protected areas recognized nationally and internationally. The purpose of this study is to present the implications of philately in promoting Romania abroad. In this sense, an attempt was made to expose a series of different philatelic effects. The pieces in question (postage stamps, First Day Covers - FDCs, maximum postcards, special envelopes and covers, etc.) that appeared on the occasion of various philatelic issues, come to warmly greet the visitor and entice him to visit these places. Moreover, through these philatelic materials (collected, indexed, and analyzed based on specialized catalogs and platforms with philatelic content), it was wanted to show that our country (Romania) is not just a Carpathian garden, but a European treasure, which transcends over the centuries through beauty and spirituality. No less than four reference philatelic issues have been discovered for the period 2009-2020, which support the idea of visiting the country, as well as the possibility to practice special cultural tourism.

Air temperature is one of the fundamental indicators of Climate Change in any place on earth. Understanding the changing patterns of air temperature in Yobe State is instrumental in establishing the manifestation of Climate Change in the area and to enables the policy makers to design the best mechanisms to cope with the vagaries of increasing temperature. This study examined the changing patterns of temperature in Yobe State as an evidence of Climate Change. The study used mean monthly minimum and maximum air temperature data collected from the archives of the Nigerian Meteorological Agency (NIMET) with respect to Nguru and Potiskum weather stations in the State for a period of 1956-2015. The data was analyzed using descriptive statistics, linear regression trend lines and coefficient of variation (C.V). The result showed that April is the hottest month with the highest mean maximum temperatures of 39.6°C and 38.6°C in Nguru and Potiskum respectively while January is the coldest month with mean temperatures of 30.5°C and 30.8°C for Nguru and Potiskum respectively. Further finding revealed that temperatures are highly variable in February in both Nguru and Potiskum with C.V of 8.7% and 5.7% and less variable in October with C.V of 2.0%. Finding showed that in general term, there were upward trends in monthly and annual positive temperature anomalies ranging from 0.2°C to as high as 4.0°C in some months and years in the state. The study concludes that temperatures in Yobe State have witnessed series of changes within the 60 years period. Therefore, it is suggested that stakeholders in the Yobe State Environmental Protection Agency should intensify efforts in reducing deforestation while encouraging people on afforestation with a view to reducing the impact of Greenhouse gases that are contributing to more warming than normal. There should be adequate electricity and water supply for immediate relieve from excessive heat emanating from high temperature.
