信天翁離婚率上升

由於海水溫度上升,一夫一妻制的信天翁繁殖變得更加困難,提高了牠們的離婚機會。 隨著環境更加惡劣,一些信天翁未能在繁殖季節返回,許多需要花費更長的時間覓食來餵養雛鳥,食物短缺也導致更多繁殖失敗。 牠們的繁殖變得有壓力,並會選擇另覓新伴侶。

due to raising water temperature, reproduction for monogamous albatross become harder and leads to higher chance of divorce. with harsher environments, some albatross failed to return for breeding seasons, many need to spend longer time to hunt for food to feed their chick and less food also leads to more failures for raising a chick. They become stressful and increase the chance to move on with someone new.

租稻田種米給瀕危鶴

瀕危的赤頸鶴每年12月到5月期間,會遷徙到柬埔寨的Anlung Pring。近年數量急劇下降,有保育團體與農民合作,以較高價租用他們的稻米田10年,並資助農民種植赤頸鶴喜愛的本地短粒米,農民可以收割一半的稻米,另一半則留下給赤頸鶴進食。

Endangered eastern sarus cranes migrate to Anlung Pring area in Cambodia during December to May, but their population dropped sharply in recent years. Conservation groups is now working with local farmers; they are renting farmlands and paying a ten-years rent in advance at a higher price, as well as paying them to plant the cranes favorites local short-grain rice. Farmers can harvest half of the rice and leave the other half for the cranes and other birds.

大火後再發現特有蜘蛛

澳洲袋鼠島特有的刺客蜘蛛(Zephyrarchaea austini)本以為只棲息於西部的一個保護區內,而該保護區在兩年前的叢林大火中被完全摧毀。 刺客蜘蛛本來被認為已經滅絕,但近月研究人員在距離牠們先前已知的棲息地約 4 公里的未燒毀區域,發現了兩隻。 科學家估計現時已認知的澳洲無脊椎物種只有 1/3 ,另外 2/3 可能在人類認識牠們之前就已經滅絕。

The endemic Kangaroo Island assassin spider (Zephyrarchaea austini) was known to live in a protected area in the west of Kangaroo Island, which was completely  destroyed by the massive bushfire two yeas ago. It was believed to be extinct but recently, researchers found two of them in an unburnt areas about 4km away from their previously known habitat. scientists estimated only 1/3 of the invertebrate species was discovered in Australia, the other 2/3 might gone extinct before human gets to know them.

電磁場影響海洋生物

蘇格蘭一項研究發現,麵包蟹會被再生能源水下電纜發出的電磁場所吸引而變得不活躍。電磁場會影響蟹的細胞,令牠們更容易受到感染,同時減少了覓食及交配,長遠影響牠們的數量。現時有關水下電力電纜如何影響海洋生物的研究很少,相信已有不少生物受到影響,特別是對鯊魚及龍蝦等對電磁敏感的動物。

A research in Scotland found that brown crabs are attracted to electromagnetic field emitted by  underwater power cables for renewable energy. The electromagnetic field affects crabs blood cells and makes them more susceptible to bacterial infection; crabs are foraging and mating less and could affect they population in long term. there are very few studies on how underwater power cables are affecting marine creatures, but its believed that many of them are affected, especially animals like sharks and lobsters that are sensitive to electromagnetism.

邀請漁民參與保育

在玻利維亞的亞馬遜叢林,漁民以往會捕捉瀕危的亞馬遜河豚作捕魚用魚餌。科學家為研究及保護,邀請當地漁民參與保育工作,透過衛星科技及智能電話去研究牠們的習性、行蹤及覓食習慣,一同去認識及了解牠們面對的威脅。

In the Bolivia‘s Amazon jungle, fishermen used to hunt endangered Amazon river dolphins and used them as bait for fishing, but now they are working with scientists and researchers to use satellite technology and smartphone app to track these dolphins in order to better understand them. as little is known about these dolphins’ diet, habits and population, scientists would need to learn more about these dolphins and their threats in order to safe them.
