| 1 | Interspecific interactions between burrowing dung beetles and earthworms on yak dung removal and herbage growth in an alpine meadow显示文摘Interspecific interactions between two spatiotemporally co-occurred species sharing a single resource are considered to be either competitive or facilitative.This study examined the possible interspecific interactions between a dung-tunneling beetle species(Onthophagus yubarinus)and an earthworm species(Aporrectodea noctuma),two major detritivores responsible for dung removal in a Tibetan alpine meadow.We conducted a two-way,factorial field experiment using replicated chambers,and measured the performances of beetles and earthworms,as well as yak dung removal,soil properties and aboveground plant biomass over two months.Earthworm presence significantly decreased the body size of beetle larvae and the weight of tunnel dung that beetle larvae live on.In contrast,beetle presence did not affect the performance of earthworms.Beetles,earthworms and their interaction significantly increased dung removal and soil organic carbon concentration at the end of the experiment.Beetles alone significantly increased soil total N and P,soluble N and P concentrations,but earthworms alone had nonsignificant effects on these nutrient variables.Beetles and earthworms additively enhanced soluble N and P concentrations,and aboveground plant biomass at the end of the experiment.These results indicate 1)there was a one-sided negative relationship between dung-tunneling beetles and earthworms,resulting from the consumption of earthworms on food resource of beetle larvae;and 2)the coexistence of beetles and earthworms facilitated dung removal interactively and plant growth additively by increasing nutrient availability. | MINGDA XIE XINWEI WU SHUCUN SUN | 2021 | Soil Ecology Letters2021，3，2： | 0 |
| 2 | Seroprevalence of human enterovirus A71 in Guangzhou,China,2019-2021显示文摘Enterovirus A71 (EV-A71) is a significant hand-foot-mouth disease (HFMD) etiology. The inactivated EV-A71 vaccines were approved in China in 2016. However, the seroprevalence of EV-A71 after the vaccine application and its potential association with the EV-A71 epidemic in the population are rarely studied. In this study, we analyzed the incidence of EV-A71 infection and seroepidemiology in Guangzhou City, China. From 2019 to 2021, 167,920 clinically confirmed HFMD cases were reported in Guangzhou. In 6,868 enterovirus-positive samples, Coxsackievirus A6 and Coxsackievirus A16 were dominant genotypes, and only 3 EV-A71-positive samples were detected, highlighting the deficient epidemic activity of EV-A71. Microneutralization assay was performed on 1,000 representative serum samples. Notably, the seroprevalence and geometric mean titer (GMT) decreased significantly in 2020, and that in the < 3-year age group were increased and even higher than that in 3–5-year age group in 2019 and 2021, which was contrary to our previous surveillance result and other studies in Guangzhou. Furthermore, a moderate decline of GMT level was observed following the vaccination, but the seropositive serums were still detected for 49 months after second immunization, suggesting the long-term persistence of the immunity. Our seroepidemiology study revealed relatively higher neutralizing antibody activity in the susceptible population after the EV-A71 vaccine was adopted in 2016 in Guangzhou. It may be one of the reasons for the lower epidemic activity of EV-A71 in Guangzhou from 2019 to 2021. | Huimin Lian Huimin Jianng Lina Yi Jing Sun Huaping Xie Ming Qiu Limei Sun Huifang Lin Mingda Yang Lin Qu Haiyi Yang Jing Lu Hanri Zeng | 2023 | Biosafety and Health2023，5，3： | 0 |
