Island hopping is not restricted to holidaying in Greece, but also an evolutionary strategy by Caribbean Pitcairnia - a group of terrestrial plants in the Bromeliad family! Here, it was found they likely radiated from Venezuela to the islands 200,000 years ago...

Male ferns of the Drypoteris affinis complex pose a problem for taxonomists & botanists alike, as ploidy level (number of complete chromosome pairs) is key for species ID, but this complex has di-, tri-, tetra- & pentaploid taxa! Stomatal length increases with ploidy, but can this be a proxy? (1/2)
Harsh conditions & challenges imposed by fragmented habitat often restrict gene flow & increase genetic structure in alpine plants. Here, the first population genetic study of the Notothlaspi plant ground in NZ revealed historical periods of contact & isolation amongst species! 🌍🧪

Stomatal length can be used as a proxy for ploidy level, so this study aimed to work out if location of sampling on the frond was important. Using 18 plants, stomatal length was measured, revealing that in most cases the correct ploidy level can be in-FERNed! (2/2) 🌍🧪👇

Pollen, the silent enemy of many around this time of year, is good for more than simply using as an excuse for crying (we see you Tracy Beaker)...
Here, the pollen of 17 species of Cryptangieae were described using an electron microscope, helping to identify species! 🌍🧪👇
Ever wondered how plants survive across fragmented environments? Reproductive flexibility! In one carnivorous plant Utricularia damazioi, being self-compatible, pollinated by bees & having the ability to self-pollinate if cross pollination fails have helped it survive...🌍🧪👇

Happy Bank Holiday! Still looking for your daily dose of Linnean journals? Here, germination strategies in a tropical hydrochoric bromeliad were compared between coastal & inland populations, revealing the role of abiotic & biotic pressures across environmental gradients! 🌍🧪
Happy #VolunteersWeeks! We're highlighting Ben Raby today, who wrote a guest blog about the use of machine learning to identify salt stress in plants. With a biology background, he's currently studying an MSc in Cleantech Innovation at Imperial! Read his blog 👇 🧪 🌍
