it as the biggest step forward in a generation. the us supreme court hears arguments in the controversial texas abortion case, with at least one legal challenge likely to be allowed to move forward. and how australian scientists have managed to produce crawling frogs that are able to adapt to climate change. hello and welcome to the programme. president biden has told the united nations climate summit in glasgow that the fight against global warming offers extraordinary economic opportunities. he said creating technologies to reduce carbon emissions would create millions ofjobs worldwide. mr biden apologised for the actions of his predecessor, donald trump, who pulled the united states out of the paris climate accords. meanwhile india s prime minister, narendra modi, has told the conference that his country aims to become carbon neutral by the year 2070. it s the first time india, one of the world biggest emitters of greenhouse gases, has announced a net zero target. our f

An essential factor in assessing the success of woodland restorations is understanding whether gene flow and connectivity between restored and remnant populations has been re-established. Without pollinator services, isolated populations can further subdivide and face concerns of inbreeding depression, which is not the target of restoration projects. Within the ‘Central Valley’ of the Warrumbungle National Park, a series of restoration plantings were performed between the 1980s and 1990s to restore the previously abundant Box-Gum Grassy Woodlands, in particular White Box Gum trees (Eucalyptus albens). Extensive land clearing meant that these populations became extremely fragmented within the agricultural matrix, with only a few remaining extant remnant trees. This restoration was discovered to use locally sourced genetic material for plantations within the park, which is known to cause issues with inbreeding depression and lower genetic variability. Extending upon previous studies,
Australian researchers find the benefits of genetic mixing between subspecies to improve genetic health and fitness outweigh risks to the Critically Endangered Helmeted Honeyeater
