繸脣蝠以蛙類為食，並能分辨不同蛙類的叫聲來捕獵。由於有些蛙類體型過大且有毒，為了找到安全的食物，這些蝙蝠學會了竊聽蛙類的求偶叫聲，並過濾掉不合適的食物。

美國俄亥俄州的一項研究發現，菊苣、紅菽草等城市的野花可能會對蜜蜂等傳粉昆蟲帶來負面影響。許多城市野花生長在曾開發的土地上，這些土地上的土壤大多含鉛、砷和鎘等有害金屬。研究人員對這些野花的花蜜進行了檢測，發現所有收集的花蜜中都至少含有一種有毒金屬，其中最常見的是鉛。花蜜中的金屬可能會損害蜜蜂等昆蟲的學習及記憶力，並影響牠們的健康。這項研究希望提高對土壤健康重要性的意識，並鼓勵在種植野花之前進行土壤測試及清理。
A study in Ohio discovered urban wildflowers like chicory and wild carrot might bring harms to pollinators like bees. Many urban wildflowers growing on previously developed land, and soil on these land have been exposed to many harmful metals such as lead, arsenic and cadmium. Researchers tested nectar from these wildflowers and discovered at least one toxic metal in all collected nectar, with lead being the most common one. Metal in nectar could affect health of insect like bees by damaging their learning ability and memory. This study wants to raise awareness of the importance of soil health, and encourage soil testing and cleanup before planting wildflowers.
澳洲維多利亞州政府用直升機狙擊手射殺一個國家公園內的700多隻樹熊。今年3月初，該國家公園約20%的土地被森林大火摧毀，那裏的樹熊遭受飢餓及傷患影響，因此政府決定射殺牠們以避免牠們遭受痛苦。野生動物組織擔心，直升機上的狙擊距離樹熊至少 30 米，於射殺前無法判斷該樹熊是否健康。而且除了射殺亦有其他解決方案，例如在森林回復期間為樹熊提供補充食物等。這次行動是首次使用空中射擊來撲殺樹熊。在新南威爾斯州、昆士蘭和澳洲首都領地，樹熊屬瀕危物種。
Over 700 koalas in a national park were shot from helicopter by the Victorian government in Australia. Earlier in March, 20% of this national park were destroyed by bushfires, and koalas there have been starving and injured, so the government decided culling is the solution to prevent their suffering. Wildlife groups were concerned that shooters on the helicopter were at least 30meters away and were not able to tell whether the koalas were healthy or not before they shoot. also, there are other solutions like delivering supplementary food for the koalas while the forest regenerates. This was the first time aerial shooting is used to cull koala. Koalas are considered endangered in New South Wales, Queensland and the Australian Capital Territory.
太平洋偏遠島嶼國家海洋保護區自 2009 年以來一直是中太平洋的保護區，但美國總統剛重新開放該地區作商業捕魚。該保護區仍有未曾受破壞的原始珊瑚礁，亦是許多野生動物的棲息地，包括瀕危海龜、海鳥、海洋哺乳動物等，其中許多也是特有物種。
the Pacific Islands Heritage Marine National Monument was a protected area in the central Pacific Ocean since 2009, but the US president has just reopened the area to commercial fishing. The Monument is home to many wildlife including endangered sea turtles, pristine coral reef, seabirds, marine mammals, etc. and many are endemic species as well.
最近研究顯示，斑尾袋鼬及北方袋鼬已在昆士蘭州「功能性滅絕」，代表牠們的數量太少，已無法在野外維持種群生存，並會導致生態系統失衡。是次調查中，共於6736個晚上設置攝影機，但並未拍攝到任何袋鼬的蹤跡。袋鼬是澳洲最大的食肉動物及頂級捕食者，但牠們正面臨棲息地喪失、入侵海蟾蜍、狐狸及野貓的威脅。
A recently study on the spotted-tail and northern quoll showed they are functionally extinct in Queensland, meaning their population is too small to sustain in the wild and lead to ecosystem imbalance. Cameras were set up for 6736 nights during this survey, and no quoll was captured. Quolls are Australia’s largest carnivore and the top predators, but they are threatened by habitat loss, invasive cane toads, foxes and feral cats.
