Presence of Alphacoronavirus in Tree- and Crevice-Dwelling Bats from Portugal

Viruses, Journal Year: 2024, Volume and Issue: 16(3), P. 434 - 434

Published: March 12, 2024

Coronaviruses (CoVs) are RNA viruses capable of infecting a wide range hosts, including mammals and birds, have caused significant epidemics such as the ongoing COVID-19 pandemic. Bats, second most diverse mammalian order, hosts for various CoVs due to their unique immune responses ecological traits. This study investigates CoV prevalence in crevice- tree-dwelling bats Portugal, country with limited prior research on bat CoVs. Using nested RT-PCR sequencing, we screened 87 stool samples from bats, identifying one sample (1.15%) that was positive Alphacoronavirus, belonging Pipistrellus pipistrellus. Phylogenetic analysis revealed close genetic relationships Alphacoronavirus strains same species Europe. The low suggests habitat-specific differences viral transmission, cave-dwelling exhibiting higher population density behaviour. These findings underscore necessity sustained surveillance efforts aimed at comprehending dynamics within populations, especially concerning risk spillover events evolution. Vital this understanding is monitoring migration patterns, which serves crucial tool elucidating ecology epidemiology. Such essential endeavours mitigating potential future zoonotic disease outbreaks.

Study of the Effectiveness of 5G Mobile Internet Technology to Promote the Reform of English Teaching in the Universities and Colleges

Journal of Cases on Information Technology, Journal Year: 2024, Volume and Issue: 26(1), P. 1 - 21

Published: April 26, 2024

With the continuous progress of information technology, distance English teaching is becoming a practical choice. The introduction 5G technology has improved classroom experience and provided innovation for modern teaching. help wireless communication teachers can effectively impart cognitive skills. Compared with traditional methods, it obviously enhances two-way between students professors. Teaching in accordance their aptitude uses reformed Best Available Technology Optimization Algorithm (RBOA) to optimize transmission process evaluate students' ability. This study shows that proposed method seems be more effective than college course significantly improve language optimization scheme potential wide application prospect practice, which injected new vitality possibility into education.

Sowerby's beaked whale biosonar and movement strategy indicate deep-sea foraging niche differentiation in mesoplodont whales

Journal of Experimental Biology, Journal Year: 2022, Volume and Issue: unknown

Closely-related species are expected to diverge in foraging strategy, reflecting the evolutionary drive optimize performance. The most speciose cetacean genus, mesoplodonts, beaked whales with little diversity external morphology or diet, and overlapping distributions. Moreover, few studied of (Ziphiidae) show closely-similar styles slow, energy-conserving movement during long, deep dives. This raises question what factors their speciation. Using data from animal-attached tags aerial imagery, we test hypothesis that two similar-sized Sowerby's (Mesoplodon bidens) Blainville's (M. densirostris) whales, exploit a similar low-energy niche. We that, compared strategist whale, whale lives fast lane. While targeting meso/bathypelagic zone, they consistently swim hunt faster, perform shorter dives, echolocate at faster rate higher frequency clicks. Further, extensive near-surface travel between dives challenges interpretation shallow inter-foraging as management decompression sickness. distinctively echolocation clicks do not hold apparent benefits. Instead, argue high-speed style influences dive duration behaviour, enabling access distinct prey population. Our results demonstrate broader deep-sea energetic niches than hitherto suspected. marked deviation typical Ziphiid strategy has potential implications for response anthropogenic sounds, which appear be strongly behaviourally-driven other Ziphiids.
