A simple index is defined that measures the contribution made by different species to phylogenetic diversity and how the index might contribute towards species-based conservation priorities and suggests that global conservation priorities may have to be reassessed in order to prevent a disproportionately large amount of mammalian evolutionary history becoming extinct in the near future.

Defaunation is both a pervasive component of the planet’s sixth mass extinction and also a major driver of global ecological change.

Taxonomic inflation: its influence on macroecology and conservation.
Statistics for citizen science: extracting signals of change from noisy ecological data
A set of candidate methods that employ data filtering criteria and/or correction factors to deal with variation in recorder activity are identified and a computer simulation is designed to compare the statistical properties of these methods under a suite of realistic data collection scenarios.
Invasive alien predator causes rapid declines of native European ladybirds
This study compares the distribution and abundance of formerly common and widespread native ladybirds before and after the arrival of Harmonia axyridis, a globally rapidly expanding IAS.

A day range model is presented and predictions against a comprehensive analysis of mammalian day range are compared to show faunivores have the longest day ranges and steepest body mass scaling and herbivores show intermediate and low scaling exponents.
How species respond to multiple extinction threats
The results show that a species' vulnerability to local extinction can be highly variable and is likely to depend on both threat type and biology, and multivariate analyses suggest that different mechanisms of decline are associated with each type of threat.
Why are metabolic scaling exponents so controversial? Quantifying variance and testing hypotheses.
It is concluded that current theories are inadequate to explain the full range of metabolic scaling patterns observed in nature, and variations in scaling are not consistent with competing explanations either.
