Ecology and evolution of pyrazines in insects

open access: yesBiological Reviews, EarlyView.
ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

Humans are not unique: difficult birth is common in placental mammals

open access: yesBiological Reviews, EarlyView.
ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult

Advances in causal discovery methods for ecological time series

open access: yesBiological Reviews, EarlyView.
ABSTRACT Recent advances in data collection technologies (e.g. automated sensor networks, satellite remote sensing, and high‐throughput sequencing) have greatly expanded the availability of ecological time series, enabling new opportunities for causal analyses in dynamic ecosystems.

On the importance of including both sexes in animal studies – insights from home‐cage monitoring

open access: yesBiological Reviews, EarlyView.
ABSTRACT A review of behavioural studies using home‐cage monitoring (HCM) systems revealed that over 61% of studies used only male subjects, with only 24% including both sexes, despite evidence of substantial behavioural differences between male and female animals. This bias could influence the outcomes of biomedical research.

The effect of intra- and interspecific interactions on the large-scale distribution of cliff-nesting raptors

open access: yes, 2008
We examine the large-scale spatial distribution and the intra- and interspecific interactions in a cliff-nesting raptor community of a semi-arid Mediterranean area in southeastern Spain.

Temporal components of interspecific interactions

open access: yes, 2018
Phenology is the annual timing of biological spring events, and includes the timing of tree budburst, the appearance of insects, and the timing of egg laying in birds. Climate warming causes phenologies of many organisms to advance, but not every level of the food web responds at the same rate to temperature.
