The impacts of biological invasions

open access: yesBiological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

A comparative analysis of the morphology and evolution of permanent sperm depletion in spiders. [PDF]

open access: yesPLoS ONE, 2011
Once thought to be energetically cheap and easy to produce, empirical work has shown that sperm is a costly and limited resource for males. In some spider species, there is behavioral evidence that sperm are permanently depleted after a single mating ...

Numerical Approaches for the Analysis of Glass Facades Under Seismic Loads

open access: yesEarthquake Engineering and Resilience, EarlyView.
Glass facades have gained more popularity due to their highly impacting esthetic and sustainable applications. However, their constitutive glass components are rather vulnerable and need proper analysis strategies to design them in efficient structural terms, especially against extreme loads, such as earthquakes.
