Validation of a X-Ray densitometry method for the determination of Eucalyptus grandis and Eucalyptus urophylla radial density profile [PDF]

, 2012
The X-ray densitometry is considered one of the main non-destructive techniques for the analysis of wood due to the high precision and practicality. The method has been applied in determining the density of the wood, and the density variation is a result

Nests in trees are as good as or better than cliffs for two formerly persecuted, primarily cliff nesting eagles in Spain: a cautionary tale in defining the habitat of range‐restricted or threatened species

Wildlife Biology, EarlyView.
In the late‐20th century, golden and Bonelli's eagles suffered population declines on the Iberian Peninsula, partly due to human persecution. Habitat assessments – especially for Bonelli's eagles – always found or assumed strong associations with cliffs that provided nesting sites.

Pantoea rodasii sp. nov., Pantoea rwandensis sp. nov. and Pantoea wallisii sp. nov., isolated from Eucalyptus [PDF]

International Journal of Systematic and Evolutionary Microbiology, 2012
Several Gram-negative-staining, facultatively anaerobic bacterial isolates were obtained from Eucalyptus seedlings showing symptoms of bacterial blight and dieback in Colombia, Rwanda and South Africa. Partial 16S rRNA gene sequencing, together with partial gyrB sequencing, placed the isolates in the genus

Digging into dirt: Rewilding with threatened mammals shapes soil‐emerging insect assemblages

Journal of Animal Ecology, EarlyView.
By comparing insect communities across treatments at two time points, we show that reintroduced digging mammals shape soil‐emerging insect assemblages. This provides empirical evidence that restoring ecosystem engineers may drive broader community‐level change in semi‐arid ecosystems. Abstract Digging mammals function as ecosystem engineers by altering

Phylogenetically‐Informed Crayfish Conservation in the Face of Climate Change

Animal Conservation, EarlyView.
Crayfish are a vital part of freshwater ecosystems, yet one third of assessed species are threatened with extinction, and almost 90% are highly sensitive to climate change. In this study, we produced a phylogenetically‐informed species prioritisation for crayfish conservation and explored the impacts of projected climate change scenarios on crayfish ...
