Terrestrial herpetofauna of Limnos and Agios Efstratios (Northern Aegean, Greece), including new species records for Malpolon insignitus (Geoffroy Saint-Hilaire, 1827) and Pelobates syriacus Boettger, 1889 (open access)

Terrestrial herpetofauna of Limnos and Agios Efstratios (Northern Aegean, Greece), including new species records for Malpolon insignitus (Geoffroy Saint-Hilaire, 1827) and Pelobates syriacus Boettger, 1889

This article presents herpetofaunal observations from Limnos and Agios Efstratios, two Asia Minor continental shelf islands in the Aegean Sea. Comprehensive surveys over 88 days in total on Limnos, over a period of nine years, consisted mainly of visual encounter surveys and road cruised observations, revealed the presence of three species of amphibians and twelve species of reptiles, including two new species records for the island (Malpolon insignitus and Pelobates syriacus). The results of these surveys provide a clearer understanding of the extant herpetofauna on Limnos and Agios Efstratios and offer discussion on natural history, possible erroneous historical records and preliminary ecological understanding of the herpetofaunal assemblages residing on these islands.

Space-charge-based electrostatic plasma confinement involving relaxed plasma species (open access)

Space-charge-based electrostatic plasma confinement involving relaxed plasma species

In this article, a numerical study is reported on the equilibrium properties of a surface-emitted or edge-confined non-drifting plasma. A self-consistent finite-differences evaluation of the electrostatic potential is carried out for a non-neutral plasma that follows a Boltzmann density distribution.

The Differences between NAD-dependent malic enzyme and NADP-dependent malic enzyme Subtypes of C4 Photosynthesis: More than Decarboxylating Enzymes (open access)

The Differences between NAD-dependent malic enzyme and NADP-dependent malic enzyme Subtypes of C4 Photosynthesis: More than Decarboxylating Enzymes

Article addresses the differences in evolutionary scenario, leaf anatomy, and especially C4 metabolic flow, C4 transporters, and cell-specific function deduced from recently reported cell-specific transcriptomic, proteomic, and metabolic analyses of NAD-dependent malic enzyme (NAD-ME) and NADP-dependent malic enzyme (NADP-ME) subtypes.

Effect of selection for commercially productive traits on the plasticity of cardiovascular regulation in chicken breeds during embryonic development (open access)

Effect of selection for commercially productive traits on the plasticity of cardiovascular regulation in chicken breeds during embryonic development

Article investigates basic cardiovascular physiology in the Red Junglefowl, the broiler, and the White Leghorn breeds at 90% of incubation. The authors aimed to identify breed-specific features of arterial blood pressure and heart rate as well as the physiological mechanisms regulating them. They concluded that selection for rapid growth shifts cardiovascular regulatory plasticity to emphasize mechanisms that modulate pressure, and that selection for egg-laying capacity emphasizes mechanisms that modulate heart rate.

Association of Host and Microbial Species Diversity across Spatial Scales in Desert Rodent Communities (open access)

Association of Host and Microbial Species Diversity across Spatial Scales in Desert Rodent Communities

Article describes study in which researchers employed a natural gradient of rodent species richness and quantified bacterial communities in rodent blood at several hierarchical spatial scales to test the hypothesis that associations between host and microbial species diversity will be positive in communities dominated by organisms with broad niches sampled at large scales.
