Mastigias papua is a jellyfish that is trademark of marine lakes. Ongeim’l Tketau Lake in Palau, Hang Du I Lake in Vietnam, Kakaban Lake in Kalimantan, and Lenmakana Lake in Raja Ampat Papua are exotic tourist destinations because of presence of these biota in the lake. Water temperature is very influential on the life of a jellyfish because of its mutual symbiosis with brown algae zooxanthellae. Mastigias has totally disappeared in several places due to water temperature increasing, including Lenmakana Lake in the West Monsoon 2017/2018 and 2018/2019. The absence of Mastigias in this lake will be explained by recorded logger data installed in the lake and at sea. Secondary data from NOAA and BMKG will be used to explain the condition of absence of jellyfish. Water lake temperature data showed an increase to 2.5oC when the Mastigias disappeared. Temperature increasing occur due to seasonal cycle patterns of lake water temperatures and weather cycles which change in time, the dry season occurs faster and the rainy season occurs slower. Conversely, in the West Monsoon 2019/2020, Mastigias still found in the lake. The rainy season which is 20 days faster than normal condition helps reduce the heat in West Monsoon.

Jakarta Bay is a bay that has an important role in Jakarta, but the activity in this area lead to the potential for pollution mainly ammonium and nitrate. Pollution peaks generally occur during the rainy season (west monsoon). Pollution that enters the bay can be neutralized naturally by water as long as the amount does not exceed the asimilation capacity. This study aims to calculate the total input (load), assimilation capacity, and residence time of ammonium and nitrate in Jakarta Bay in the rainy season. Data from this study is derived from secondary data. For the total input of pollutants are calculated from the input stream, the atmosphere and the boundary. From the research found that the Jakarta Bay had a total load of pollutants NH4 at 115.8 x 109 mmol N /month and NO3 46.5 x 109 mmol N/month. The biggest contributor to the pollution comes from the boundary NH4 is 56.9% and NO3 from the river 70.1%. Load from Citarum river for NH4 around 3.8 x 1010 mmol N/month and NO3 around 3.0 x 1010 mmol N/month higher than Marunda, Priok and Angke the rivers. Assimilation capacity of Jakarta bay  for NH4 around 25.7 x 109 mmol N /month and NO3 of 24.1 x 109 mmol N /month. It shows the total load of pollutants entering the Jakarta Bay is greater than the assimilation capacity. The residence time of water in the Bay of Jakarta is 13.3 days longer than the residence time of NH4 and NO3 which were only 8.6 and 9.2 days.

This study investigated the boreal digging frog, Kaloula borealis, to determine the egg hatching period and whether the hatching period is affected by incubation temperature. The results of this study showed that all the eggs hatched within 48 h after spawning, with 28.1% (±10.8, n=52) hatching within 24 h and 99.9% (±0.23, n=49) within 48 h after spawning. A significant difference was noted in the mean hatching proportion of tadpoles at different water temperatures. The mean hatching rates between 15 and 24 h after spawning was higher at a water temperature of 21.1 (±0.2) °C than at 24.1 (±0.2) °C. These results suggest that incubation temperature affected the early life stages of the boreal digging frog, since they spawn in ponds or puddles that form during the rainy season.

Geology of Greenland Survey Bulletin, 186, 78-82. https://doi.org/10.34194/ggub.v186.5219 _______________ Climate and water temperature have an important influence on the functioning of lake ecosystems. From limnological and palaeolimnological studies of lakes, information on biological diversity and climate variability in time and space can be gleaned from physical, chemical and biological indicators preserved in the lake sediments. The lakes in southern West Greenland are particularly useful for this purpose – they are numerous, diverse and have minimal anthropogenic impact (Anderson & Bennike 1997). Palaeolimnological data are fundamental for understanding the functioning and development of modern lakes and for understanding the causes of climatic change as well as the effect on lake biota.

AbstractTourism is vitally important to the Austrian economy. The number of tourist destinations, both farms and other forms of accommodation, in the different regions of Austria is considerably and constantly changing. This paper discusses the position of the ‘farm holiday’ compared to other forms of tourism. Understanding the resilience of farm holidays is especially important but empirical research on this matter remains limited. The term ‘farm holiday’ covers staying overnight on a farm that is actively engaged in agriculture and has a maximum of 10 guest beds. The results reported in this paper are based on an analysis of secondary data from 2000 and 2018 by looking at two types of indicator: (i) accommodation capacity (supply side) and (ii) attractiveness of a destination (demand side). The data sets cover Austria and its NUTS3 regions. The results show the evolution of farm holidays vis-à-vis other forms of tourist accommodation. In the form of a quadrant matrix they also show the relative position of farm holidays regionally. While putting into question the resilience of farm holidays, the data also reveals where farm holidays could act to expand this niche or learn and improve to effect a shift in their respective position relative to the market ‘leaders’. However, there is clearly a need to learn more about farm holidays within the local context. This paper contributes to our knowledge of farm holidays from a regional point of view and tries to elaborate on the need for further research.

The purpose of this study was to determine the hydrodynamic conditions at Bojong Salawe beach. The method used in this research is a quantitative method, where numerical data is collected to support the formation of numerical models such as wind, bathymetry, and tide data. The hydrodynamic model will be made using Mike 21 with the Flow Model FM module to determine the current movement pattern based on the data used. In the west monsoon with a maximum instantaneous speed of 0.04 - 0.08 m/s, while in the east monsoon it moves with a maximum instantaneous speed of 0,4 – 0,44 m/s. The dominant direction of current movement tends to the northeast. The results indicate the current speed during the east monsoon is higher than the west monsoon. The difference in the current speed is also influenced by the tide conditions; higher during high tide and lower during low tide. Monsoons also have a role in the current movements, though the effect is not very significant.

Pilgrimage Tourism

India is a large country with great traditions, culture, and civilization. India has 4000 years of fertile civilized life with planned cities, monumental temples, mosques and churches,  palaces,  sculptures,  paintings  and  various artistic creations. These scenic beauties have made India one of the most famous tourist destinations in the world. The Tourism potential of any country mainly depends on its climate, scenery, historical monuments, arts, tradition, festivals  and  the  society.  If  any  place  or  area  or  spot possesses all these characters and potentials, we may call it  as  a  tourist  centre  or  pilgrim  centre.  Tamil  Nadu,  a southern State of India, is a land of charm with ancient traditions;  the  picturesque  land  of  Tamil  Nadu  has towering temples  with  magnificent  architecture  and sculptures,  art  galleries  and  heterogeneous  natural beauty, existing on the hills and mountains. Tamil Nadu is flooded with different cultural, spiritual and religious centres  like  Madurai,  Rameswaram,  Kanyakumari, Tanjavur,  Kumbakonam,  Trichy,  Kancheepuram, Chidambaram,  Tiruvannamalai  and  Palani.  Religious institutions like temples in Tamil Nadu have been playing a  multifaceted  role in  religious,  social,  economic  and cultural life of the Tamil community. Moreover, temples are  considered  as producers,  land  owners,  trustees,employers,  pilgrim  centres  and  institutions.    There  are studies  conducted  in  cultural  and  spiritual tourism centres, which focus on heritage, culture and the historical aspects.  But  studies  that  focus  on  economic  aspects  of such  centres  are  scanty.  With  this  background,  the authors have made an attempt to study the memories and reminiscence  of  150  Pilgrimage  tourists,  who  visited Palani Temple; one of the Six abodes  of Lord Muruga located in the Dindigul district of Tamil Nadu, with an objective  of  examining  the  social and  economic characteristics  of the pilgrimage  tourists;  and  identify their major problems and suggest ways and means for promoting  pilgrimage  tourism  in  Palani.  The  Primary data has been collected through interview schedules. The interview  schedule  was  pre-tested,  modified and  well- structured, and was used for obtaining information and data from the cultural-spiritual tourists, who are visiting the Palani temple. Secondary data in connection with the Palani temple were also gathered from the office of the Commissioner, Palani temple. Further, the authors have collected  data  and  information  from  150  tourists  who visited  the  Palani  temple  during  June-July  2011.  The tourists  were purposively selected in different spots in and  around the Palani  temple.  For  the  purpose  of analyzing the data, simple tools like ratio, percentage and average were used

This study was carried out using Moderate Resolution Imaging Spectroradiometer (MODIS) 1 km × 1 km resolution records on board Terra and Aqua satellites and in-situ measurements during the period (2003–2019). In spite of the presence of increasing atmospheric warming, in summer when evaporation is maximal, in fresh-water Lake Kinneret, satellite data revealed the absence of surface water temperature (SWT) trends. The absence of SWT trends in the presence of increasing atmospheric warming is an indication of the influence of increasing evaporation on SWT trends. The increasing water cooling, due to the above-mentioned increasing evaporation, compensated for increasing heating of surface water by regional atmospheric warming, resulting in the absence of SWT trends. In contrast to fresh-water Lake Kinneret, in the hypersaline Dead Sea, located ~100 km apart, MODIS records showed an increasing trend of 0.8 °C decade−1 in summer SWT during the same study period. The presence of increasing SWT trends in the presence of increasing atmospheric warming is an indication of the absence of steadily increasing evaporation in the Dead Sea. This is supported by a constant drop in Dead Sea water level at the rate of ~1 m/year from year to year during the last 25-year period (1995–2020). In summer, in contrast to satellite measurements, in-situ measurements of near-surface water temperature in Lake Kinneret showed an increasing trend of 0.7 °C  decade−1.

Indirect Rule

This paper argues that the British colonialists introduced indirect rule to deliberately slow down development in Nigeria and therefore examines how policies influenced the nature and character of socio-cultural and political activities in Nigeria, as well as made it dependent on the west for the sustenance of its economy. It adopts the Dependency Theory as theoretical framework. The study is qualitative and thus obtained secondary data from text books, journals, newspapers and magazines both online and offline, which were content analyzed and formed the basis of conclusion. It observed that the colonial masters had deliberate policies that negatively affected the post-colonial development of Nigeria. It recommended, amongst others, a comprehensive restructuring and overhaul of the political and economic structures that impede development, as well as the reawakening of the consciousness of Nigerians for veritable development.
