Background:The European rabbit(Oryctolagus cuniculus l.1758)was introduced into different regions of the world,generating significant trade‑offs that critically impacted native ***,we evaluate the rabbit’s forage intakes in three vegetation types(forests,shrublands,and grasslands)along the four seasons in a temperate forest landscape in Southern Patagonia and discuss the potential threats over native *** formulated the following questions:(i)what is the forage offer at each vegetation type?(ii)what is the rabbit’s forage intake and how it varied across the seasons along the year?and(iii)which vegetation types and plant life forms were more used according to the rabbit’s forage intakes?Methods:We censused understory vegetation to characterize the forage offer at each vegetation type and determined seasonal dietary intakes using microhistological analysis of *** plant species identified in the field were grouped according to life form classes(tree regeneration,shrubs,forbs,graminoids,orchids,ferns,bryophytes,and hemiparasites).Data were analysed through uni‑and multi‑variate analyses,determining relationships between forage offer and the rabbit’s forage ***:Forage intakes revealed changes in plant life form consumption across vegetation types,where intake pressure was considerably different for tree regeneration(p=0.001),graminoids(p=0.001),and hemiparasites(p=0.001).Besides,significant changes in consumption among seasons were detected for shrubs(p=0.001),ferns(p=0.030),and hemiparasites(p=0.002).Although many species play an important role in the rabbit’s forage intake networks(e.g.,Chiliotrichum diffusum,Holcus lanatus),the strongest intake linkages were found in exotic grasses(e.g.,Poa pratensis and Festuca sp.),native hemiparasites(e.g.,Misodendrum sp.),native shrubs(e.g.,Empetrum rubrum),and native trees(e.g.,Nothofagus sp.).The summer and autumn seasons presented higher intake compared to the winter and spring seasons.F

This article describes a study on a non-thermal plasma device to treat exhaust gases in an internal combustion engine. Several tests using a plasma device to treat exhaust gases are conducted on a Honda GX200- 196 cm3 engine at different rotational speeds. A plasma reactor could be efficient in degrading nitrogen oxides and particulate matter. Monoxide and carbon dioxide treatment is minimal. However, achieving 1%-3% degradation may be interesting to reduce the emission of greenhouse gases.

腐植酸(HA)通过调节植物的激素和氧化还原代谢来刺激几种植物种类的生长,然而,关于HA与植物相关菌群的关系鲜有报道。本文中,我们假设HA效应与植物相关细菌群落的调控同时发生,水稻在施用或不施用HA(80 mg/l)的营养液中生长264 h,每24 h评价1次植株生长,施用240 h后取样品进行16S rRNA基因测序。第1次施用HA后,从100 h到264 h植株净同化率、绝对生长率和相对生长率增加,根系体积和其他生长变量在植物生长周期的不同时间受到刺激。宏基因组分类揭示,使用HA后细菌群落结构和组成受到影响,HA处理的根部,群落成员间的相互作用增强,显示更多关联更密切的细菌群落,鞘氨醇菌属(Chitinophaga)和粘液杆菌属(Mucilaginibacter)是HA处理后根系的优势菌属。据报道,这些细菌能产生酶,降解真菌、卵菌和线虫卵壁中的化合物。铁载体产生者和植物生长促进者——假单胞菌(Pseudomonas)和酸杆菌Gp1(Acidobacteria Gp1)均富集,虽然丰度较低。鉴于这些结果,我们认为植物组建这些微生物是为了应对HA—根互作引起的胁迫。我们的研究结果首次表明,受HA刺激的植物可能采用组建细菌群落成员的生态策略,这些细菌群落成员是抑制病原体的候选者,因而参与植物防御.
