Wilting wildflowers and bummed‐out bees: Climate change threatens US state symbols

open access: yesPeople and Nature, EarlyView.
Abstract Species designated as state symbols in the United States carry cultural importance, embody historical heritage and maintain long‐standing linkages to Indigenous traditions. However, they are threatened by climate change and even face the risk of local or global extinction.

Varied motivations for secondary forest reclearing among landholders make forest persistence challenging

open access: yesPeople and Nature, EarlyView.
Abstract Remote sensing studies show that ephemeral forest regeneration is widespread in the tropics, limiting the climate and biodiversity benefits from net increases in forest cover. Socioeconomic, biophysical and landscape variables can help explain the spatial distribution of reforestation reversals.

Bionisch inspirierte Strahlungskühlung: Kühlen wie die Silberameise

open access: yesPhysik in unserer Zeit, EarlyView.
Wie kann ein wenige Millimeter großes Insekt helfen, Gebäude ohne Strom zu kühlen? Die Silberameise überlebt extreme Hitze mithilfe raffinierter Mikrostrukturen, die einen Großteil des Sonnenlichts zurückwerfen und gleichzeitig thermische Energie über Infrarotstrahlung in den Weltraum abführen.

Digitisation of herbarium specimens to the benefit of research: An African perspective focusing on South Africa and Western Indian Ocean Island states

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Botanical exploration, discovery and conservation rely heavily on access to herbarium collections. Recently, digital access to label information, including georeferenced locality data, and images of herbarium specimens available online have greatly increased usage of herbarium specimen data.

Detecting extirpation: A localized approach to a global problem

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
The global biodiversity crisis stems from a cascading series of extirpations driving species toward extinction. Addressing this crisis requires methods for early detection of extinction at local scales, where communities can mobilize conservation efforts.
