Cheaters among pollinators: Nectar robbing and thieving vary spatiotemporally with floral traits in Afrotropical forests

Autor: Sailee P. Sakhalkar, Štěpán Janeček, Yannick Klomberg, Jan E. J. Mertens, Jiří Hodeček, Robert Tropek

Publikováno v: Ecosphere, Vol 14, Iss 11, Pp n/a-n/a (2023)

Abstract Nectar robbers and thieves are common antagonists in plant–pollinator communities, where they deplete nectar without pollinating flowers, substantially affecting plant reproduction. Nevertheless, little is known about the relative abundanc

Publikováno v: Scientific Reports, Vol 11, Iss 1, Pp 1-12 (2021)

Abstract Butterflies and moths are conspicuous flower visitors but their role in plant-pollinator interactions has rarely been quantified, especially in tropical rainforests. Moreover, we have virtually no knowledge of environmental factors affecting

Publikováno v: Plants, Vol 10, Iss 6, p 1161 (2021)

Despite a growing number of studies, the role of pollinators as a selection agent for nectar traits remains unclear. Moreover, the lack of data from some biogeographic regions prohibits us from determining their general importance and global patterns

The pollination syndrome hypothesis predicts that plants pollinated by the same pollinator group bear convergent combinations of specific floral functional traits. Nevertheless, some studies have shown that these combinations predict pollinators with

Background The biodiversity of West and Central Africa is understudied, including butterflies and moths (Lepidoptera). Cameroon, through its position in between few biogeographic regions and diversity of habitats, is an important hotspot of lepidopte
