Do floral and ecogeographic isolation allow the co-occurrence of two ecotypes of Anacamptis papilionacea (Orchidaceae)? [PDF]
Ecol Evol, 2021 Without geographic isolation, gene flow usually homogenizes the allopatrically generated phenotypic and ecological divergences, unless other forms of reproductive isolation keep them separated. Here, we investigated two orchid ecotypes with marked phenotypic floral divergence that coexist in contact zones.

Molecular Ecology, Volume 32, Issue 23, Page 6449-6460, December 2023., 2023 Abstract Urbanization is affecting arthropod communities worldwide, for example by changing the availability of food resources. However, the strength and direction of a community's response is species‐specific and depends on species' trophic level. Here, we investigated interacting species at different trophic levels in nests of cavity‐nesting bees and

Psyche: A Journal of Entomology, Volume 2018, Issue 1, 2018., 2018 Ectatomma tuberculatum has one of the most toxic venoms known among ants but there is no detailed study on its characteristics. In light of this, knowing the venom’s chemical composition is of paramount importance in order to obtain information about the mechanisms of its components.

Psyche: A Journal of Entomology, Volume 2016, Issue 1, 2016., 2016 Plant‐animal interaction has been a major theme in ecology as it has helped ecologists to rule out different patterns they observed in the surrounding environments. Chromolaena odorata is another plant species that is studied extensively as it has become a major troublesome weed in many parts of the tropics.

Psyche: A Journal of Entomology, Volume 2012, Issue 1, 2012., 2012 Pollination biology of the invasive plant sulfur cinquefoil (Potentilla recta L.) and it′s native cooccurring congener slender cinquefoil (P. gracilis Dougl. ex. Hook.) was studied from 2002–2004, at four sites in northeastern Oregon, USA The native cinquefoil flowered first for five weeks, followed by the invasive for five weeks, with two weeks ...
