Limited impact of climate change on seed maturation time in Myrica esculenta Buch-Ham. Ex. D.Don in Himalayan region



Shruti Shah, Ashish Tewari



Climate influences plant recruitment at a global
scale. Asynchronized reproduction with climatic factors may lead to
failure of regeneration. The object of the present study was to monitor
flowering and fruiting phenology in one important under canopy forest
species Myrica esculenta, Buch-Ham. Ex. D.Don of the Himalayan region.
The study was undertaken at two times across a decade on similar sites
2004 and 2013. Variation in time of fruiting and flowering was
insignificant between 2004 and 2013. In Yr 2004 across all the dates the
fruits and seeds were bigger in size in compared to Yr 2013 but there
was no significant difference in fruit size, weight of 100 fruits and
number of fruits per 100g. However, seed size (P<0.01), weight of 100
seeds (P<0.05) and number of seeds per 100g (P<0.05) varied
significantly in Yr 2004 and Yr 2013. In Yr 2013 maximum germination
63.33± 3.33% occurred when fruit moisture content was 69.48 ± 0.93% and
moisture content of seed was 31.96 ± 0.94%. ANOVA showed that moisture
content of fruit and moisture content of seed (P<0.01) varied
significantly across the years whereas there was no significant
difference in germination in both the years. It was apparent from the
study that each species will respond differently and have its own
adaptation strategy against changing climate. Generalizing, that all
species will show variations in their phenophases due to climate change
may be an incorrect assumption. It is evident that all species will
develop their own adaptational strategies to cope with climatic
irregularities.

The Ecological Impacts of Light Pollution at Night-time a Mechanistic Appraisal

The Ecological Impacts of Light Pollution at Night-time a Mechanistic Appraisal Abdullahi MG, Roslan U, Kamarudin M. K. A. Artificial light at night and its negative consequences are of great interest in the fields of Ecology, Human Geography Astronomy, and Human Health. Most of the studies to date concentrated on the influences of light pollution has on our ability to view the night sky, on biodiversity, and ecosystems. Though, in recent years, with the use of new technologies sensors, which provide accurate information for determining of night lights at the area, most consideration were given for estimating artificial light at night within the urban areas. In this study, urban night lights within the cities of Nigeria was evaluated by monitoring data from the ground measurements using Sky Quality Meter (SQM-LU-DL) devices. Besides, the SQM was used at the zenith (upward direction) for maximum evaluating of artificial light at the sites. Differences in night sky bri...

Studying the tendency of citizens to participate in the protection and development of land scape in Tehran

Studying the tendency of citizens to participate in the protection and development of land scape in Tehran Shadi Maleki, Abbas Mafi, Seyedeh Mahsa Hosseini Today, as an essential part and parcel of urban landscape that they play a major role in metabolism and create a lack of serious damage to urban life. This study performed to investigate the willingness of citizens to participate in activities to protect and develop landscapeof Tehran district 4. The research was descriptive and correlation method that is used for collecting information. The statistical population consisted of district 4 of Tehran. The sample size was determined 230 by using Cochrane method. A questionnaire was used to collect data. According to the research, 63.04 percent of citizens showed participation in a high level. Among the variables investigated how citizen participation in conservation and development of landscape, effective strategies to motivate citizens to participate,the reasons for la...

Land Use Land Cover Change Detection by Using Remote Sensing Data in Akaki River Basin

Land Use Land Cover Change Detection by Using Remote Sensing Data in Akaki River Basin Adimasu Woldesenbet Worako   Land use land cover change (LULCC) is the result of the long time process of natural and anthropogenic activities that has been practiced on the land. GIS and remote sensing are the best tools that support to generate the relevant land use/cover change in the basin. This study was conducted in the Akaki River basin to detect land use land cover changes within the 30 years period (1985-2015) by using landsat imagery data acquired from the GCF. Supervised maximum likelihood algorithm classification were deployed to classify land use/cover into four prominent land use groups and data’s were processed by using ERDAS imagine 2014 and ArcGIS10.1 software. In the basin dominant LULC was agricultural land use which accounts around 56.28% and the second largest is built-up area by 31.51% and the rest, forest(11.9%) and water body(0.31%) coverage were takes t...
