Journal Introduction: The Invasive of Pomacea canaliculata in Indonesia (ARYA)

 



Recently, I found interesting journal for me about “the invasive of apple snail Pomacea canaliculata in Indonesia: in Lake Rawa Pening” this journal written by Mrs. Ristiyanti (LIPI, Indonesia), Mr. Heryanto  (LIPI, Indonesia) and Mr. Joshi (CABI) and published in 2020. This journal showed us some effect of invasive species threat native species population. Well, before I am explaining the interesting part of this journal better to explain first the different of this species. Golden apple snail, P. canaliculata, is an invasive species from South America. It was distributed in many parts of the world including Indonesia. Golden apple snail sometime become trouble for rice plant production as they can consuming paddy seedling. Pink is the colour of their egg and we can see the eggs in the plant parts above the water area. This is their strategy to survive from some predator. So, how about Indonesia native species? Indonesia native snail is Pila scutata. Indonesia native snail is not so dangerous such as golden apple snail because they do not eat all kind of plant. The distribution nowadays is not widespread as they can’t survive in polluted water. The colour of P. scutata egg is white but they also laid the eggs above the water in some part of the plant.

As a student who study about freshwater snails this is very interesting as native species can’t compete with the invader. The study of this journal held on lake in Rawa Pening, Indonesia. In this journal mention from a whole area P. canaliculata can be found everywhere and P. scutata (native species) only be found in 6 location. It said that P. canaliculate could adapted well and ate all kind of plants there. This behaviour can be treating for Indonesia native snail which feeds only preferred plants. The population of P. canaliculata in Rawa Pening Lake are increasing day by day followed with water hyacinth (Eichornia crassipes) growth. Both species has positive correlation and it potentially decrease the number of P. scutata. I think we need to consider and understand more the ecology of both species to avoid some extinction and loss of diversity in our nature.  

最近、夫人が書いた「インドネシアのスクミリンゴガイの侵入種：ラワペニング湖」についての興味深いジャーナルを見つけました。 Ristiyanti（LIPI、インドネシア）、Mr。 Heryanto（LIPI、インドネシア）とMr. Joshi（CABI）であり、2020年に発行されました。このジャーナルは、侵入種が在来種の個体数を脅かす影響を示しています。さて、私がこのジャーナルの興味深い部分を説明する前に、最初にこの種の違いを説明する方が良いでしょう。ゴールデンアップルカタツムリ、P。canaliculataは、南アメリカからの侵入種です。インドネシアを含む世界の多くの地域で配布されました。スクミリンゴガイは水田の苗を消費する可能性があるため、イネの生産に支障をきたすことがあります。ピンクは彼らの卵の色であり、私たちは水域の上の植物の部分で卵を見ることができます。これは、ある捕食者から生き残るための彼らの戦略です。では、インドネシアの在来種はどうですか？インドネシア原産のカタツムリはPilascutataです。インドネシア原産のカタツムリは、あらゆる種類の植物を食べないため、ゴールデンアップルカタツムリのようにそれほど危険ではありません。彼らは汚染された水で生き残ることができないので、今日の分布は普及していません。 P. scutataの卵の色は白ですが、植物の一部の水面に卵を産みました。


淡水カタツムリについて研究する学生として、在来種は侵入者と競争できないため、これは非常に興味深いものです。インドネシアのラワペニングの湖で開催されたこのジャーナルの研究。このジャーナルでは、地域全体からの言及で、P。canaliculataはいたるところに見られ、P。scutata（在来種）は6か所でしか見られません。 P. canaliculateはうまく適応でき、そこであらゆる種類の植物を食べることができると言われています。この行動は、好ましい植物だけを養うインドネシアの在来カタツムリを治療することができます。ラワペニング湖のP.canaliculataの個体数は日ごとに増加しており、ホテイアオイ（Eichornia crassipes）が増加しています。両方の種は正の相関関係があり、P。scutataの数を減らす可能性があります。私たちは考慮し、理解する必要があると思います

HAZARD VS. RISK-BASED APPROACHES TO PROTECTING HEALTH (ERNEST)

                                               HAZARD VS. RISK-BASED APPROACHES TO PROTECTING                             HEALTH AND ENVIRONMENT FROM PESTICIDES                                                                      April 2021     What’s the difference between a hazard and risk-based approach? These two approaches are often presented as opposing. However, this is a misrepresentation of risk management. ‘Hazard’ is the potential for a chemical (in this case a pesticide) to cause harm to human health or the environment; Risk , on the other hand , is the probability that the harmful outcome happens. Hazard cannot be separated from risk; it is an integral part of it. Pesticide risk management focuses on reducing the probability (and hence frequency), that people or the  environment will be exposed to pesticides. The hazard-based approach to pesticide regulation is founded on the principle that if an active substance possesses certain hazardous character

Locust as a source of food and feed (Rahima)

イメージ
I came across a pack of roasted locusts at the store the other day and decided to check their nutritional value and study a bit more about them. Locusts are a type of insect from the family Acrididae . They are known to swarm in huge numbers and can travel great distances, causing considerable damage to crops. However, in many African, Middle Eastern, and Asian countries, locusts are considered a delicacy and eaten in abundance. Locusts are an excellent source of protein and contain a variety of fatty acids and minerals. Although not considered palatable by most Americans and Europeans, locusts are an important food source in many other countries.   According to the book "Insects" by Steve Parker, species of locusts vary in protein content from about 50 percent of dry weight to almost 60 percent, making them denser in protein than cows . Researchers have also noted that the cholesterol content in locusts is high, about 286 milligrams per 100 grams, which is higher than th

Full vaccination（Sagae）

イメージ
We some of the lab members had second vaccination at university. It was so hard situation for me because of side effects. I had heard some news that the side effects of the second vaccine are more serious. It was TRUE. The night after the vaccine, started to increase my body temperature. At midnight temperature already reached 38.5 ℃. And also my bone has pain and "Moderna arm". I could only lay on the bed the whole day by agony. My fever continues till next midnight. I thought my fever had gone down, but then I started to have terrible headaches. Again I spent the time on the bed the whole day. Finally, I recovered fully after 60 hours of vaccination. It was the worst experience in 2021 at least. I wish our painfulness contributes to making the situation better. 大学で二回目のワクチン接種を受けました。結論から言うと、副反応が本当きつかったです。二回目は一回目より副反応がきついと聞いていましたが、その通りです。接種日の夜から熱が上がり始めて、夜中には38.5℃に達しました。きつすぎてベッドに横になる事しかできません。全身の関節は痛むし、モデルナアームも発症しています。次の夜中は明朝まで高熱は続きました。熱が下がったと思ったら次はひどい頭痛です。またベットから動けず一日を過ごします。最終的
