Rank-abundance curves, correspondence analysis (CA), Bray-Curtis beta diversity partitioning, nonmetric multidimensional analysis (NMDS), and similarity analysis (ANOSIM) were performed. In total, 841 individuals of 24 species were collected. The most abundant species was Angiopolybia paraensis (Spinosa 1851). Community structure and composition change according to the disturbance levels, with a balanced variation of Bray-Curtis of 85.65%. The most diverse forest is the most conserved (SLR). Five species were recorded exclusively in SLR and three in PCR. We concluded that vespids are good indicators of environmental quality since their populations present marked preferences and changes in their composition.

A�������. In Semiarid Chaco, two management approaches for woody plant-encroached grassland/savannas were evaluated: ecological restoration and the African grass introduction. An experiment with five treatments was carried out: 1) reference community (Ref_Eco; a grassland/savanna in good state, used as standard of comparison); 2) grassland/savanna encroached by woody plants (Woody_Encr; the woody state of grassland/ savannas); 3) roller chopping of the encroached ecosystem, followed by grazing suppression and prescribed fire (Roll_Fire; aimed at inducing grassland/savanna ecological restoration); 4) roller chopping of the encroached ecosystem, with instantaneous seeding of Megathyrsus maximus cv. Ga�on Panic and grazing suppression (Roll_Ga�on Panic), and 5) roller chopping of the encroached ecosystem, with instantaneous seeding of Cenchrus ciliaris cv. Buffel Texas and grazing suppression (Roll_Buffel Texas). The last two treatments aimed to obtain new highly productive grassy states for ranching through the introduction of these African grasses. The results suggested that Ref_Eco (average herbaceous biomass [HERB]=7196.9 kg DM/ha) was dominated by shade intolerant and fire tolerant grasses, and it had good soil quality and good utilitarian range condition. Regarding Ref_Eco: a) in Woody_Encr (HERB=2192 kg DM/ha), the vegetation structure, plant composition and the utilitarian range condition were altered, but it still had good soil quality and abundant native grass populations; b) in Rol_Fire (HERB=6591.6 kg DM/ha), both the vegetation structure and good utilitarian range condition were restored, plant composition was not restored and the good soil quality was kept, and c) Roll_Ga�on Panic and Roll_Buffel Texas (HERB=10972.1 and 7450.8 kg DM/ha, respectively) resulted in new grassy states integrated by native and exotic grasses with good utilitarian range condition and good soil quality. In this study case, the ecological restoration of the encroached ecosystems would be both ecologically and productively viable. So, probably the introduction of African grasses to improve ranching was not necessary.
A.�������. 在半干旱的查科，对木本植物侵占草原/稀树草原的两种管理方法进行了评估：生态恢复和非洲草的引入。对五个处理进行了实验：1）参考群落（Ref_Eco；一个状态良好的草原/稀树草原，用作比较标准）；2） 被木本植物侵占的草原/热带草原（woody_Encr；草原/热带稀树草原的木本状态）；3） 碾压被侵占的生态系统，然后进行放牧和规定的火灾（Roll_fire；旨在诱导草原/稀树草原生态恢复）；4） 利用Megathyrsus maximus cv.Ga的瞬时播种对被侵占的生态系统进行碾压�关于恐慌和放牧抑制（Roll_Ga�对Panic），以及5）对被侵占的生态系统进行滚筒式砍伐，并立即播种Cenchrus cilaris cv.Buffel Texas和抑制放牧（Roll_Buffel Texas）。最后两种处理旨在通过引入这些非洲草来获得新的高产牧场。结果表明，Ref_Eco（平均草本生物量[HERB]=7196.9 kg DM/ha）以耐荫和耐火草为主，具有良好的土壤质量和良好的实用范围条件。关于Ref_Eco:a）在Woody_Encr（HERB=2192kg DM/ha）中，植被结构、植物组成和有效范围条件都发生了改变，但它仍然具有良好的土壤质量和丰富的原生草种群；b） 在Rol_Fire（HERB=6591.6 kg DM/ha）中，植被结构和良好的实用范围条件都得到了恢复，植物成分没有得到恢复，保持了良好的土壤质量，并且c）Roll_Ga�在Panic和Roll_Buffel Texas（HERB分别为10972.1和7450.8 kg DM/ha）上，本地和外来草形成了新的草地状态，具有良好的实用范围条件和良好的土壤质量。在本研究案例中，被侵占生态系统的生态恢复在生态上和生产上都是可行的。因此，引入非洲草来改善牧场可能没有必要。
