An Overlooked Habitat‐Dependent Link Between Metabolism and Water Loss in Reptiles

Integrative Zoology, EarlyView.
We measured the gas exchange of six lizard and six snake species, under high and low air humidity, and two intriguing patterns emerged. First, although desert species lose less water via evaporation than similar‐sized mesic species under similar conditions, water loss is virtually the same when each is exposed to its natural conditions.

Persistence and dynamic of forest snails in the Western Carpathians over the last 40 thousand years

Boreas, EarlyView.
The glacial/interglacial cycles have shaped the landscape of temperate Europe for the past 2.5 million years, with open landscapes prevailing during the glacial and forested landscapes during the interglacial periods. However, the survival and recolonization strategies of temperate forest species during glacial phases remain poorly understood and hotly

The Light and Heavy Scalars in Unitarized Coupled Channel and Lagrangian Approaches

, 2003
Using ideas underlying the flavour-blind "Nijmegen Unitarised Meson Model" we try to understand on the basis of a system of Schroedinger equations with one meson-meson and one (spinless) quark-antiquark channel coupled by a simple delta-shell transition ...

Meson Masses and Energetics of Meson Decay [PDF]

American Journal of Physics, 1952
A series of measurements of the π- and μ-meson masses and their decay energies is reviewed. Recent mass measurements made at the University of California Radiation Laboratory have employed an improved method in which the ratio of the π-meson mass to that of the proton and the ratio of the μ-meson mass to that of the π-meson were determined by measuring

Meson Reactions in Deuterium and Meson-Nucleon Scattering [PDF]

Progress of Theoretical Physics, 1952
Various meson reactions in deuterium are investigated on the basis of impulse approximation. Then one obtains the close connection between deuteron data and nucleon data, which is shown to be useful to get an insight into the spin- and charge-dependences of meson-nucleon interaction.

Reversibility of sex changes in the plant kingdom: more important than we thought?

Biological Reviews, EarlyView.
ABSTRACT Compared to animals, plants show a wide range of reproductive strategies with different degrees of sex separation (e.g. dioecy, monoecy, hermaphroditism). While sex expression was previously thought to be genetically determined and fixed in plants, accumulating evidence suggests that sex expression can change reversibly even within one ...

What controls forest litter decomposition? A coordinated distributed teabag experiment across ten mountains

Ecography, EarlyView.
Litter decomposition in mountainous forest ecosystems is an essential process that affects carbon and nutrient cycling. However, the contribution of litter decomposition to terrestrial ecosystems is difficult to estimate accurately because of the limited comparability of different studies and limited data on local microclimatic and non‐climatic factors.

The conservatism of prairie pollinators according to experts and empiricism

Insect Conservation and Diversity, EarlyView.
We derived ecological conservatism values for prairie pollinators using expert opinion and analysis of remnant fidelity. Expert values were potentially biased and struggled to differentiate between remnant and non‐remnant prairie sites Empirical values showed advantages for pollinator‐based site assessment and prioritization in prairie regions ...

Species‐ and trait‐based responses of carabids to rotation and closer‐to‐nature forestry in a temperate forest under changing climate

Insect Conservation and Diversity, EarlyView.
Species‐specific responses of insects to forest management remain partly unfolded, thus ground beetles and their traits were studied in five different forestry treatments. Clear‐cuts and retentions had the most negative impact while habitat generalists and species with flexible breeding period have no response.

Taking stock after 6 years—The first results of an ongoing project to establish new populations of a regionally endangered grasshopper Számvetés az első hat év után—egy regionálisan veszélyeztetett sáskafaj új populációinak létrehozását célzó projekt első eredményei

Insect Conservation and Diversity, EarlyView.
A conservation programme started in 2018 to establish new populations of the regionally endangered large banded grasshopper (Arcyptera fusca) in two mountain ranges in Hungary, Central Europe. Between 2018 and 2024, individuals were translocated to five mountain meadows from nearby populations by single or repeated translocations.
