Transactions in GIS, Volume 30, Issue 2, April 2026.ABSTRACT This study presents the first deep‐learning time‐series benchmark for detecting two encroaching species in the Brazilian Cerrado: the native super‐dominant fern Pteridium arachnoideum and the invasive alien shrub Tithonia diversifolia. We evaluate 43 architectures across six families (CNNs, RNNs, Transformers, and three hybrid groups) on ...

Southern Perú coseismic subsidence: 23 June 2001 8.4-Mw earthquake [PDF]
Advances in Geosciences, 2008 The 23-June-2001 8.4-Mw magnitude earthquake partially filled the 1868-seismic-gap in southern Perú. This earthquake produced a thrust faulting dislocation with a rupture that started at about ~200 km SE from the 1996's Nazca earthquake epicenter ...

Global Ecology and Biogeography, Volume 35, Issue 2, February 2026.ABSTRACT Aim The assembly of montane plant communities through time is underlain by historical and abiotic factors. However, the extent of evolutionary connectivity between ancient highland ecosystems and surrounding lowlands remains unclear. Here, we investigate the evolutionary connections between the campos rupestres, a hyperdiverse and fragmented ...

Flooding in the Tamanduateí River Hydrographic Basin: A Spatial and Multifactorial Analysis
Transactions in GIS, Volume 30, Issue 1, February 2026.ABSTRACT Understanding the occurrence of urban floods and their conditioning factors is essential for effective management of urban watersheds. However, few studies have explored the spatial variability of these factors in detail. This study investigates the spatial relationships between conditioning factors and flood occurrences in the Tamanduateí ...
