Herpetological misinformation and sensationalism: media framing on biological and ecological aspects of the golden lancehead (Bothrops insularis)

  Herpetological misinformation and sensationalism: media framing on biological and ecological aspects of the golden lancehead (Bothrops insularis) Abstract The internet is currently one of the most important means of communication, which may include the circulation of misinformation. Snakes have always been a target of the sensationalist media, being pictured as scary and aggressive animals to be killed indiscriminately by humans. Such fear based on misinformation may compromise species conservation. Here, we address the spread of misinformation about Bothrops insularis and Queimada Grande Island in digital media, highlighting the negative impact on public perception and species conservation. The analysis of 230 online sources revealed that approximately 94% of them contained false information, many using sensationalist language, especially regarding the toxicity of the venom and the population density of the snake, as well as bringing contents that did not align with scientific d...

A large brush-footed trapdoor spider (Mygalomorphae: Barychelidae) from the Miocene of Australia

Abstract

The aridification of the Australian continent led to the diversification of mygalomorph spiders in the Miocene, but a depauperate fossil record has made it difficult to investigate evolution across this epoch. Here, we describe the first fossil barychelid spider (Araneae: Barychelidae) in the world and the second fossil mygalomorph spider from Australia. It is placed as a new genus and species (Megamonodontium mccluskyi gen. et sp. nov.). Megamonodontium resembles Monodontium Kulczyński, 1908, a genus that persists in rainforests through Singapore, Indonesia and Papua New Guinea. The new specimen is the second largest spider fossil in the world and is approximately five times larger than extant Monodontium. The fossil shows that this lineage once occupied mesic rainforest habitats in Australia but has since been replaced by other spiders.
