APLICAÇÕES DOS MODELOS DE ELEVAÇÃO SRTM EM GEOMORFOLOGIA / SRTM DEMs APPLICATIONS IN GEOMORPHOLOGY

Revista Geográfica Acadêmica, 2008
The Shuttle Radar Topography Mission (SRTM) was realized to map the morphology of the Earth’scontinental areas between 60ºN and 54ºS, using radar interferometry. Application of Digital ElevationModels (DEMs) in geomorphology allow calculation of topography-related variables with speed andprecision.

Beyond the breeding grounds: identifying post‐breeding staging areas, corridors and ecological niche of the Lesser Kestrel

Ibis, EarlyView.
The post‐breeding period is a critical yet overlooked phase in the annual cycle of migratory birds, where individuals must resolve competing bioenergetic trade‐offs between recovery from breeding, moult and migratory fuelling. Using GPS data from 54 adult Lesser Kestrels Falco naumanni tracked across Spain, we analysed 76 post‐breeding tracks to ...

Rhododendron diversity patterns provide new insights for conserving China's montane flora

Journal of Integrative Plant Biology, EarlyView.
Integrating distribution, phylogenetic, and functional trait data for 603 Rhododendron species in China identified significant conservation hotspots of multidimensional diversity, particularly in the Hengduan Mountains. Climate seasonality and topographic heterogeneity jointly influenced these patterns; however, notable conservation gaps remained ...

Nature, nurture, and 5‐HT4R: Familial predisposition, not parental bonding, is associated with brain 5‐HT4R in a sex‐specific manner

Psychiatry and Clinical Neurosciences, EarlyView.
Background Major depressive disorder (MDD) aggregates in families. The neostriatum, key to reward and attachment circuits, has the highest density of serotonin 4 receptors (5‐HT4R). Striatal 5‐HT4R is low in MDD and linked to familial depression risk. Poor parental bonding increases depression risk, yet whether nature and nurture converge on 5‐HT4R is ...

Home Range and Habitat Selection of the Endangered Red Goshawk (Erythrotriorchis radiatus) Across Australia's Tropical Savannas

Ecology and Evolution, Volume 16, Issue 8, August 2026.
We used long‐term GPS tracking to quantify home‐range size and habitat selection of the endangered Red Goshawk across tropical savannas of northern Australia. Red Goshawks occupied extensive overall home ranges, with well‐defined core ranges centred on nest sites.

Improved land cover mapping using aerial photographs and satellite images

Open Geosciences, 2014
Manual Land Cover Mapping using aerial photographs provides sufficient level of resolution for detailed vegetation or land cover maps. However, in some cases it is not possible to achieve the desired information over large areas, for example from ...

Temperature fluctuations controlled episodic rockfall activity in the Rwenzori Mountains (Uganda) during the Holocene

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
The alignment between rockfall deposit surface exposure 10Be ages and Holocene temperature records suggests that major rockfall events occurred episodically in response to climatic fluctuations. We conclude that temperature and its evolution enabled mechanical, chemical or bio‐chemical enhancement of fracture progression.
