A cross-domain tropical species dataset with Chinese vernacular names and CITES source links

Announce Type: new Abstract: We describe a versioned cross-domain dataset of 410,499 active tropical species (working snapshot 2026-04-20) spanning three applied subdomains -- tropical_plants, tropical_aquatic, and tropical_pets -- that share a commercial and regulatory life cycle but are distributed across kingdom-organised biodiversity infrastructures. The resource joins taxonomic identifiers from GBIF, Plants of the World Online, iNaturalist, NCBI Taxonomy, the Catalogue of Life and the...

Hong Kong braces for heat, showers as tropical depression passes nearby

Hong Kong braces for heat, showers as tropical depression passes nearby Forecaster says typhoon warning unlikely, as tropical depression shows limited strengthening and weak northern convection Hong Kong’s weather forecaster is monitoring a tropical depression that has formed within 800km (497 miles) of the city, but says it is unlikely to issue a typhoon warning signal. The Hong Kong Observatory said on Thursday that an area of low pressure over the northeastern part of the South China Sea...

How positive tipping points may be the key to protecting tropical rainforests

How positive tipping points may be the key to protecting tropical rainforests Gaby Clark Scientific Editor Andrew Zinin Lead Editor The world's tropical rainforests are edging towards collapse. But knowing how to stop deforestation isn't enough to drive action. The challenge is aligning all the pieces of the puzzle to initiate substantial change.

Daddy longlegs may be capturing and devouring frogs in the tropical forests of South America

Daddy longlegs may be capturing and devouring frogs in the tropical forests of South America Daddy longlegs have been observed eating frogs in South America, suggesting that these arachnids may be predators of vertebrates. Daddy longlegs have been spotted devouring live frogs bigger than themselves in the tropical forests of South America, a new study reports. And this behavior might be more common than scientists expected.

Tropical storm Jangmi injures 9 in Japan, thousands without power

Tropical storm Jangmi injures 9 in Japan, thousands without power Public transport in Tokyo and nearby cities could face disruptions as the storm approaches. A severe tropical storm battered southwestern Japan on Tuesday (Jun 2), knocking out power to tens of thousands of homes, grounding hundreds of flights and injuring nine people. The Japan Meteorological Agency warned of high waves, landslides and flooding as storm Jangmi - which was downgraded from a typhoon - rumbles northwards after...

Tropical storm Jangmi batters Japan, cuts power to 60,000 homes

Tropical storm Jangmi batters Japan, cuts power to 60,000 homes Evacuation advisories were issued to hundreds of thousands of residents in eight prefectures across southwestern, central and eastern Japan. Severe tropical storm Jangmi ripped across Japan on Wednesday (Jun 3) morning, with fierce winds and torrential rain disrupting transport and businesses, and knocking out power for tens of thousands of homes. The storm's centre lay off the central, main island of Honshu, tracking northeast...

Residual Pseudospectra Reveal a Physics-Informed Koopman Backbone for Tropical Pacific Variability and ENSO Prediction

Announce Type: new Abstract: Tropical Pacific sea-surface-temperature (SST) variability spans interacting timescales, with the ENSO as its dominant interannual expression. Yet the dynamical structure organizing this variability and underpinning extended-range predictability remains difficult to extract from high-dimensional observations. Koopman operator learning offers spectral coordinates for nonlinear dynamics, yet finite geophysical records often produce dense, sampling-sensitive spectra...
