theguardian.comElusive nightingale ‘doing well’ at Northward Hill, Kent, but experts cite concerns around loss of habitatThe dawn chorus at RSPB Northward Hill in Kent is a riot of sound: the melodic robin, the two-tone cuckoo, the whitethroat’s scratchy warble. Even the garbling geese and mooing cows from the neighbouring Thames marshes add to the symphony.But in late April one energetic singer hogs the limelight. For a few weeks after arriving from West Africa, the nightingale spends the night – and early morning – in complex song. As it searches for a mate and marks its territory, its song is at times as sweet and tuneful as a soul singer, at others as frantic as a car alarm. Continue reading...
theguardian.com• Researchers from Woods Hole Oceanographic Institution reported that Atlantic cod and other commercial fish populations have rebounded 34% over the past four years following strict catch quotas and marine protected areas implemented in 2022. • Population surveys conducted across 850,000 square kilometers of Atlantic waters show biomass increases in previously depleted stocks, with detailed findings presented at the American Fisheries Society conference on April 19. • The recovery demonstrates that science-based fisheries management can restore ecosystems within a decade, providing a model for international ocean conservation efforts.
phys.orgAmericans having less kids plus an ageing population could be a recipe for disaster that further erodes social stabilityRemember environmentalist Paul Ehrlich’s 1960s-vintage prediction about how overpopulation would deplete the Earth’s resources and condemn millions to starvation? His Malthusian condemnation of humanity’s voracious appetite has kept a grip on the debate over the future of the planet, even scaring the young out of having children.Ehrlich was wrong. Yet as we have come around to the thought that overpopulation won’t kill us all, we are being walloped by another demographic emergency: we are not having too many kids, we are having too few. This problem is real. Continue reading...
theguardian.comExperts say our preoccupation with net overseas migration figures has distracted from a more meaningful discussion on the ‘scale of temporariness’Get our breaking news email, free app or daily news podcastAustralia should set immigration targets to achieve a “stable temporary population” to address the ballooning number of nonpermanent residents that has stretched the country’s public services and housing, a new report argues.Temporary migrants as a share of the total population has more than doubled over the past 15 years, from 2.7% in 2010, to more than 6%.

Afbeelding: Live Science• A new study published in the journal Science documents that climate change is making fish smaller, posing significant threats to global food security and fishery productivity. • The research warns that the shift toward smaller fish species could worsen fishery losses by as much as 50%, impacting both commercial fishing industries and food availability worldwide. • The findings highlight the cascading ecological effects of climate change on marine ecosystems and underscore the urgency of addressing global warming to protect food systems.
