Examples from the living world that have analogues in engineering design are ball-and-socket joints, aerodynamic forms and laminated materials. What inspiration the natural world might have to offer the engineer came under consideration at a stimulating meeting held in Berlin in June. 
Managing wet grassland landscapes : impacts on predators and wader nest predation
Assessment of the distribution of mammalian predators and their small mammal prey in a landscape managed for breeding waders within lowland wet grasslands shows that small mammals are almost entirely restricted to tall vegetation, which is rare and typically occurs only in verges outside fields.

Trophic control of mesopredators in terrestrial ecosystems: top-down or bottom-up?
This work analyses the response of a mesopredator (the red fox) to declines in top predators and agricultural expansion over 90 years in Sweden, taking bioclimatic effects into account. Expand
Marine ecological footprint indicates unsustainability of the Pohnpei (Micronesia) coral reef fishery
SUMMARY Throughout the tropics, developing countries and territories are highly dependent on nearshore marine resources for food and income, however information on the sustainability and properExpand

Ecological correlates of the spatial co-occurrence of sympatric mammalian carnivores worldwide.
Co-occurrence probabilities were greatest for species pairs that shared ecological traits including similar body size, temporal activity pattern and diet, but decreased as compared to other species pairs when the pair included a large-bodied carnivore. Expand
A photographic survey of mammalian trail use in Big Basin Redwood State Park

Myeloid leukemias have increased activity of the nonhomologous end-joining pathway and concomitant DNA misrepair that is dependent on the Ku70/86 heterodimer.
The findings suggest that an overactive NHEJ system and, specifically, aberrant Ku70/86 activity is a candidate mechanism for chromosomal instability in myeloid leukemias. Expand
DNA double strand breaks (DSB) and non-homologous end joining (NHEJ) pathways in human leukemia.
Some of the ways in which error-prone NHEJ repair may be involved in the development of genomic instability and leukemia are discussed. Expand
Increased error-prone NHEJ activity in myeloid leukemias is associated with DNA damage at sites that recruit key nonhomologous end-joining proteins.
It is shown that in myeloid leukemia cells and normal hemopoietic cells, agents that induce DSBs produce an up to 2-fold increase in this DSB misrepair activity, whereas an alkylating agent produces little or no increases. Expand
