Conventional economic models often overlook the complex ways people value nature, highlighting the need for more inclusive approaches to address biodiversity loss.
Old-fashioned economic thinking is driving biodiversity loss—study calls for shift in how we value nature
Old-fashioned economic thinking is driving biodiversity loss, according to a new international study led by Aberystwyth University academics, which calls for a fundamental shift in how nature is valued.

Shannon's H, Simpson's D, and Pielou's J are useless in ecology. Fitting data with a compound abundance distribution based on the geometric series is a better way to quantify variation – and to estimate species richness. New paper in Ecology Letters.

Lakes are crucial for biodiversity 🌍

#DYK Lake Ohrid, a European biodiversity hotspot, hosts unique species but faces threats from human activity?

.—@ipbes.net #GlobalAssessment🧪

On #WorldLakeDay, let’s highlight the value of lakes, their sustainable management & the ecosystems they support.
Landscape photograph of Lake Ohrid, showing a vast expanse of deep blue rippling water in the foreground. The lake stretches to distant mountains that form the horizon line. Snow-capped peaks are visible on the higher mountain ranges. Under a bright blue sky, scattered white clouds create a serene atmosphere. The shoreline visible in the distance shows green forested areas and some buildings nestled along the coast. The water's surface has a gentle wave pattern, creating a textured appearance across the lake.

Lakes contain most of the liquid fresh water on the planet, but they are also among the most rapidly degrading ecosystems.

Ahead of #WorldLakeDay on August 27, see how you can take #GenerationRestoration action to safeguard these vital freshwater bodies: www.decadeonrestoration.org/lakes
A person stands on a boat in a lake, raising a hand holding aquatic plants, with mountains in the background and playful line drawings of birds, fish, and a palm tree overlaid. Large white text reads “LET’S REVIVE OUR LAKES” with “Join #GenerationRestoration” beneath, and the UN Decade on Ecosystem Restoration 2021–2030 logo appears in the bottom left corner.

Lago Nero (black lake) di Cornisello at 2240 m was rather green when we sampled it. An algal bloom!! This meant changing filters every few minutes.
That night, our faces were of similar color (stomach bug) and we skipped the last lake.

Lago Nero, one of the more accessible mountain lakes on our tour. Impressive backdrop, but we had little time to admire it. Millions of microscopic algae turned the waters green. What species will it be once we analyze the filters in the lab?

Our next set of mountain lakes is located in Italy's Adamella Brenta Nature Park. Lago Serodoli (2370 m elevation) is just downstream of Lago Gelato (2388 m), which lived up to its name and made us shiver with ice-cold winds.

🔥 2024 was the hottest year on record.

Decision makers must prioritize #ClimateAction for both people and the planet. The window to secure a livable future is rapidly closing.

Report: unstats.un.org/sdgs/report/... #SDGReport #SDGs #GlobalGoals
This graphic from the SDG Report 2025 shows that 2024 was the hottest year on record, with global temperatures reaching 1.55°C above pre-industrial levels. It features a rising temperature graph from 1850 to 2024 and includes SDG 13: Climate Action.
