Urban density strongly correlates with house sparrow health

House sparrows (Passer domesticus) have adapted to urban environments, which are changing and growing faster than ever before. A range of both biotic and abiotic factors—including habitat fragmentation, changing food availability, ...

What makes some creatures more afraid of change than others?

Humans are undoubtedly altering the natural environment. But how wild animals respond to these changes is complex and unclear. In a new study published today, scientists have discovered significant differences in how the ...
