Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. For much of the 20th century, Cuba’s spiders and scorpions received limited attention beyond specialist circles. Identifying them required careful research in museum collections and comparing them with descriptions published abroad. Giraldo Alayón García spent much of his career documenting Cuba’s arachnids and bringing them to the public’s attention. In San Antonio de los Baños, southwest of Havana, he used Radio Ariguanabo to discuss wildlife with a general audience. At the National Museum of Natural History of Cuba, where he spent almost four decades, he helped build one of the Caribbean’s principal collections of arachnids. At the museum, he curated specimens collected in Cuba and elsewhere in the Caribbean, and added the records that made the collection useful to other researchers. Under Alayón, the museum’s arachnological collection became one of the Caribbean’s most substantial. In 1994, he published a list of Cuba’s spiders, which became a standard point of reference for work on the island’s arachnids. Across his career, he described about 95 species and genera, most of them endemic to Cuba. He also worked abroad. From 1993 to 1995, he directed the Arachnological Project of Yucatán in Mexico. In 1999, he led an expedition to Navassa Island — contested between Haiti and the U.S. — where researchers identified several species new to science. One, the scorpion Cazierius alayoni, was named for him. Alayón first took wildlife to a wider audience on Radio…This article was originally published on Mongabay

Rising sea levels due to climate change could damage hundreds of thousands of properties and millions of hectares of land along Australia’s coastline by 2100, according to a recent study. This could cost the country an economic loss of $855 billion, researchers estimate. To calculate the costs, researchers in Australia used existing projections of sea level rise and storm surges to map out the areas that could suffer flooding by 2100. Then they identified all the houses, properties, agricultural land, and other land and infrastructure in the vulnerable areas and used real estate sources to estimate their values and arrive at what their damage could cost. The analysis showed that by 2100, under a scenario where greenhouse gas emissions remain moderate, sea level rise and storm surges could damage roughly 268,000 properties and 2 million hectares (4.9 million acres) of land in Australia. That’s a present-value economic loss of $855.1 billion. Under a high-emissions scenario, nearly 720,000 properties and 3.7 million hectares (9.1 million acres) of Australian coastal properties could suffer damage, amounting to present-value losses of up to $1.91 trillion. “Sea level rise may physically affect a large number of Australians who live near the coast, as the majority of Australians live within 50 kilometres [31 miles] of the coastline,” Tom Kompas, study lead author and a professor of environmental economics and biosecurity at the University of Melbourne, said in a statement. Australia’s coastline is massive, extending roughly 34,000 kilometers (21,000 miles). The analysis found that every region of…This article was originally published on Mongabay
