Biology of the Gall Midge Spanolepis selloanae (Diptera, Cecidomyiidae), a Candidate Biological Control Agent of the Invasive Grass Cortaderia selloana

Entomologia Experimentalis et Applicata, EarlyView.
Spanolepis selloanae (Diptera, Cecidomyiidae) infests Cortaderia selloana (pampas grass). It lays eggs in the spikelets, where larvae feed on female parts. The high prevalence of the midge and its combined impact in seed production, condition and viability strongly reduces the reproductive output of C. selloana.

Dietary selectivity mediates niche overlap and interspecific competition in a reedbed warbler community in southern Europe

Ibis, EarlyView.
Sympatric species are expected to use resources differently along one or more ecological dimensions. This can be complex when there is partial separation along multiple dimensions, such as where bird species exhibit similarities in habitat use and diet.
