Assessing the Presence, Pattern, and Environmental Correlates of Seasonal Skin Thickening in Anurans
Integrative Zoology, EarlyView.Histological sections, like that of the ventral pectoral skin of Lithobates pipiens, were measured to assess variation in skin thickness throughout the year in three North American anuran species. After correcting for individual body size, we test whether skin thickness changes throughout the year and which factors (environment or life history) explain

Flavonoids from the flowers of Nymphaea alba L.
Acta Societatis Botanicorum Poloniae, 2014 Ten flavonoids were obtained from the flowers of Nymphaea alba L. Their structures were determined mainly on the basis of spectral analyses (UV, 'H NMR, MS). The following aglycons were isolated: quercetin, kaempferol, isokaempferide and apigenin as well

Chloride fluxes in lily pollen tubes: a critical reevaluation
, 2004 Microelectrodes, made from a Cl?-selective liquid ion exchanger previously used to measure putative Cl- fluxes in Lilium longiflorum pollen tubes, were characterized. The electrodes were poorly selective, possessing only about 10-fold selectivity for Cl?

Acta Zoologica, EarlyView.ABSTRACT In this study, the egg‐laying behaviour and chorionic morphology of the eggs of the backswimmer Notonecta viridis Delcourt, 1909 (Heteroptera: Notonectidae) were described in detail using stereo, light and electron microscopy. Female N. viridis lays its eggs individually, horizontally attached to the surface. Eggs are elliptical, approximately

Integrating migratory connectivity data into the conservation of Australian sharks and rays
Conservation Biology, EarlyView.Abstract Understanding migratory connectivity is important for conserving highly mobile marine species facing escalating threats. Establishing baseline information on migratory connectivity is necessary for identifying species and regions requiring transboundary cooperation for their conservation.

The Place for Form in Wollheim's Lectures on Formalism and Pictorial Organization
European Journal of Philosophy, EarlyView.Abstract At the time of his death, Richard Wollheim was writing a short book on Formalism and Pictorial Organization. Much of it, but by no means all of it, had been published before (it has come out posthumously in its entirety in late 2025). Here I do two things. First, I have provided a rather detailed exegesis concentrating on the parts of the book

Catalysis and allostery in bacterial ATP phosphoribosyltransferases
The FEBS Journal, EarlyView.ATP phosphoribosyltransferase (ATPPRT) catalyses the first reaction of L‐histidine biosynthesis. L‐Histidine allosterically inhibits ATPPRT to regulate this energy‐intensive pathway in histidine‐synthesising organisms, such as bacteria, archaea and plants.
