Complex demographic, developmental, fitness, and physiological responses of larval eastern hellbenders to elevated water conductivity

Journal of Zoology, EarlyView.
Here we explore the effects of elevated water conductivity on larval eastern hellbenders (Cryptobranchus a. alleganiensis), both lethal and sublethal. We found that elevated water conductivity significantly impacts both survival and morphology, though it has limited effects on locomotor performance, stress physiology, and oxidative stress.

Hybridity of mainly asexually propagating duckweeds in genus Lemna – dead end or breakthrough?

New Phytologist, EarlyView.
Summary The cosmopolitan, mainly vegetatively propagating, organ‐reduced monocotyledonous aquatic duckweeds are the smallest and fastest growing angiosperms, distributed world‐wide and flower rarely in nature. Recently, we reported intra‐ and interspecific hybrids and ploidy variants in the genus Lemna.

Climate adaptation and functional constraints drive pollen evolution in Apiales

New Phytologist, EarlyView.
Summary Pollen grains exhibit remarkable morphological diversity, shaped by selective pressures from environmental factors and mechanical constraints. Here, we investigate macroevolutionary patterns of pollen morphology in Apiales, an order of angiosperms with significant ecological and geographical diversity, to disentangle the roles of climate and ...
