Size Matters: Trap Size Primarily Determines Prey Spectra Differences Among Sympatric Species of Carnivorous Sundews

Snapshot prey spectrum analysis of the phylogenetically early-diverging carnivorous Utricularia multifida from U. section Polypompholyx (Lentibulariaceae)

“…Comparative analyses from several sites are necessary to investigate this further, as recently performed in the Droseraceae for the aquatic waterwheel plant ( Aldrovanda vesiculosa ) [ 47 ] and for terrestrial annual sundews from Drosera sect. Arachnopus [ 48 ]. Due to the highly ephemerous nature of U .…”

<p><strong>A new species of <em>Drosera </em>section <em>Arachnopus </em>(Droseraceae) from the western Kimberley, Australia, and amendments to the range and circumscription of <em>Drosera finlaysoniana</em></strong></p>

“…The majority of Drosera species are perennial herbs, only 16 of them are annual therophytes (Fleischmann et al 2018), including all eleven currently recognised species of Drosera section Arachnopus Planchon (1848: 93; which sits within D. subgenus Drosera per the infrageneric classification of Fleischmann et al 2018). In addition to their annual life cycle, most species of this section, sometimes referred to as the "D. indica Linnaeus (1753: 282) species complex", are characterised by their relatively large, erect habit and narrowly linear-lanceolate, carnivorous leaves (Lowrie 2014, Krueger et al 2020. Additionally, some species exhibit complex non-carnivorous glands or trichomes on their leaves, stems and inflorescences (Schlauer 2001, Lowrie et al 2017a or produce a strong, honey-like scent from their leaves which may play a role in prey attraction (Lowrie 2014, Fleischmann 2016, Krueger et al 2020.…”
