Mathematical chaos in simple growth models has grave consequences for theoretical ecology. Much effort recently been directed towards delimiting the conditions under which exists. We have performed an empirical search among 27 drosophilid species at two temperatures, and found that single—species laboratory populations invariably exhibited dynamical stability. argue stable limit cycle behavior are maladaptive, propose evolutionary mechanism whereby group selection stability occurs.
Summary Autoprothrombin I, autoprothrombin II, and II-A have been derived from bovine prothrombin concentrated. I is formed when thrombin used to activate which has chromatographed on IRC-50 or diethylaminoethyl cellulose. The activation inhibited by calcium ions, goes more rapidly as the alkalinity increased up pH 9.7. During liberation of acidic groups predominates over that basic groups. In mixtures proline, alanine, threonine valine were found N-terminal amino acids. activity was...
This paper presents the specification, design, and development of Visible Camera (VIS) on European Space Agency's mission. VIS is a large optical-band imager with field view 0.54 deg$^2$ sampled at an array 609 Megapixels spatial resolution . It will be used to survey approximately 14 000 extragalactic sky measure distortion galaxies in redshift range $z=0.1$--1.5 resulting from weak gravitational lensing, one two principal cosmology probes leveraged by With photometric redshifts,...
Compared with their free-ranging counterparts, wild animals in captivity experience different conditions lasting physiological and behavioural effects. Although shifts gene expression are expected to occur upstream of these phenotypes, we found no previous comparisons captive versus mammals. We assessed profiles three brain regions (cortex, olfactory bulb hippocampus) shrews ( Sorex araneus ) compared kept for two months undertook sample dropout examine robustness given limited sizes....
The Soft X-ray Imager (SXI) is part of the scientific payload Solar wind Magnetosphere Ionosphere Link Explorer (SMILE) mission. SMILE a joint science mission between European Space Agency (ESA) and Chinese Academy Sciences (CAS) due for launch in 2025. SXI compact telescope with wide field-of-view (FOV) capable encompassing large portions Earth's magnetosphere from vantage point orbit. sensitive to soft X-rays produced by Wind Charge eXchange (SWCX) process when heavy ions solar origin...
Captivity, frequently used in animal research, can profoundly alter brain size, cognitive abilities and activity levels. Critically, persistent exposure to stressors captive environments lead chronic stress subsequently a range of health issues. However, the direct implications captivity on research outcomes have not been thoroughly investigated. We examined effects common shrew, Sorex araneus , species that exhibits profound seasonal reversible change body size. compared wild shrews during...
Contrasting almost all other mammalian wintering strategies, Eurasian common shrews, Sorex araneus , endure winter by shrinking their brain, skull, and most organs, only to then regrow breeding size the following spring. How such tiny mammals achieve this unique brain plasticity while maintaining activity through remains unknown. To discover potential adaptations underlying trait, we analyzed seasonal differential expression in shrew hypothalamus, a region that both regulates metabolic...
Abstract Sorex araneus , the Eurasian common shrew, has seasonal brain size plasticity (Dehnel’s phenomenon) and abundant intraspecific chromosomal rearrangements, but genomic contributions to these traits remain unknown. We couple a chromosome-scale genome assembly with transcriptomes discover relationships between molecular changes both traits. Positively selected genes enriched Fanconi anemia DNA repair pathway, which prevents accumulation of aberrations, is likely involved in...

Abstract The genus Myotis is one of the largest clades bats, and exhibits some most extreme variation in lifespans among mammals alongside unique adaptations to viral tolerance immune defense. To study evolution longevity-associated traits infectious disease, we generated near-complete genome assemblies cell lines for 8 closely related species . Using genome-wide screens positive selection, analyses structural variation, functional experiments primary lines, identify new patterns adaptation...
ABSTRACT First isolated from neotropical fruit bats in Trinidad 1956, Tacaribe virus (TCRV) has rarely been detected since.

The common shrew, Sorex araneus , is a small mammal of growing interest in neuroscience research, as it exhibits dramatic and reversible seasonal changes individual brain size organization (a process known Dehnel’s phenomenon). Despite decades studies on this system, the mechanisms behind structural during phenomenon are not yet understood. To resolve these questions foster research unique species, we present first combined histological, magnetic resonance imaging (MRI), transcriptomic atlas...
Abstract To meet the challenge of wintering in place many high-latitude small mammals reduce energy demands through hibernation. In contrast, short-lived Eurasian common shrews, Sorex araneus , remain active and shrink, including energy-intensive organs winter, regrowing spring an evolved strategy called Dehnel’s phenomenon. How this size change is linked to metabolic regulatory changes sustain their high metabolism unknown. We analyzed metabolic, proteomic, gene expression profiles spanning...
