Adapting to Urban Heights: Multidimensional Gradients Drive Nest‐Selection Plasticity and Trade‐Offs in a Human‐Commensal Sparrow

open access: yesIntegrative Zoology, EarlyView.
Urban Eurasian tree sparrows exhibit pronounced nest‐site plasticity, exploiting vertical building space while preferring lower nest heights when sites are abundant. Nest decisions are driven by altitude and building height rather than other factors, indicating a shift toward anthropogenic resources in cities.

Comparison of fractal dimensions based on segmented NDVI fields obtained from different remote sensors. [PDF]

open access: yes, 2012
Satellite image data have become an important source of information for monitoring vegetation and mapping land cover at several scales. Beside this, the distribution and phenology of vegetation is largely associated with climate, terrain characteristics ...

Rethinking Spatial Prioritisation for Primate Conservation in an Unprotected Intact Forest Landscape in the Gulf of Guinea

open access: yesAnimal Conservation, EarlyView.
This study highlights the importance of the unprotected Yabassi Key Biodiversity Area, Cameroon, for primate conservation in the Gulf of Guinea biodiversity hotspot. We modelled primate distribution patterns and found that historically overlooked parts of the landscape have high species richness and are critical for some threatened species.

Sanitation felling against the European spruce bark beetle: A matter of intensity and forest type Tagli fitosanitari contro il bostrico tipografo: una questione di intensità e tipologia forestale

open access: yesAgricultural and Forest Entomology, EarlyView.
We assess the effect of sanitation felling performed in 2022 in North‐Eastern Italy on bark beetle damage that occurred in 2023 across eight spruce forest types, as evaluated using multispectral satellite imagery. Bark beetle damage was reduced only at very high or very low sanitation felling rates.

Multi‐Spectral Gaussian Splatting with Neural Color Representation

open access: yesComputer Graphics Forum, EarlyView.
Abstract 3D Gaussian Splatting (3DGS) [KKLD23] has transformed novel‐view synthesis from RGB images, yet remains restricted to the visible spectrum. Many applications, including agricultural monitoring, rely on multi‐spectral imaging, where spectral camera alignment and scalability pose major challenges.

Providing regular and frequent maps of losses and gains of farmland birds based on European monitoring data

open access: yesConservation Biology, EarlyView.
Abstract Knowledge of species distributions is essential for informing policies on nature conservation and restoration. However, updating them on a regular basis and doing so in a harmonized manner at the international level is difficult. The European Bird Census Council integrated national monitoring data covering 5 years to update farmland bird ...

Centering geospatial data uncertainty and the potential for injustice in pastoralist rangeland conservation prioritization

open access: yesConservation Biology, EarlyView.
Abstract Procedural, distributional, recognitional, and epistemic justice aspects of conservation interventions are well documented in contexts where pastoralism is a key livelihood and way of life. Geospatial analyses and representations of wildlife conservation and restoration that are increasingly applied in pastoralist rangeland socioecological ...

Integrating remote‐sensing and meteorological data to identify key drivers of the potential distribution of a grassland grasshopper

open access: yesEcological Entomology, EarlyView.
An ensemble model achieved excellent accuracy (AUC = 0.973) in predicting the potential distribution of O. decorus asiaticus. Climate (temperature & August precipitation) and vegetation type are the primary drivers defining the species' suitable habitats.

ANALYSIS OF VEGETATION COVER CHANGES USING NORMALIZED DIFFERENCE VEGETATION INDEX (NDVI) IN BIRNIN KEBBI, NIGERIA

open access: yes
Vegetation absorbs carbon dioxide from the atmosphere, thereby mitigating the impact of global warming and climate change and also preventing desertification. In Nigeria, desertification poses a threat to the livelihoods of numerous communities, particularly in the northern region.
