Weak negative responses of spider diversity to short-term ‘kraaling’

چکیده
The influence of short-duration, concentrated kraaling (enclosure) has been documented for plants, wildlife, and macro-invertebrates. However, limited information is available on its impact ground-dwelling spiders. purpose this study was to assess the effect short-duration kraaling, time since cattle removal, microhabitat variables spider assemblages in Matabeleland North Province, Zimbabwe. We used a matched-pair space design (inside vs outside previously kraaled inclusions) across 11 sites, using four herds (H1, H6, H7 HNguni). Spiders were sampled early late rainy season with pitfall traps left open 14-day sampling periods emptied twice each period. captured 634 spiders, comprising 63 species 44 genera 18 families. most abundant family Lycosidae (37%; 16 spp.), followed by Gnaphosidae (15%; 10 spp.) Salticidae (14.5%; 7 spp.). Generalised linear mixed models showed that generic richness greater sites more bare ground. reversed particularly evident abundance responded negatively relative unkraaled sites. Furthermore, U-shaped recovery, increased kraaling. Model-based multivariate had significant assemblage structure, but relatively small compared seasonality. Most made contributions response less Spider diversity, therefore, weak negative short-term these impacts should also be assessed at broader scales, including areas where go graze during day.

Scientists predict climate changes and warmer conditions for the world in future. Predicting the warming effect on plant performance is one of the most important challenges in ecological sciences. In this study, the effects of short-term warming on physiological traits of Pteropyrum aucheri as one of the domain shrubs was assessed in riverside of semi-arid rangelands of Kohpanj region, Bardsir,...
متن کاملAn Analysis of Short-Term Responses to Threats of Terrorism
T important defensive mechanisms available to governments combating terrorism are warnings and the deployment of physical resources. Warnings are relatively inexpensive to issue but their effectiveness suffers from false alarms. Physical deployments of trained security personnel can directly thwart attacks but are expensive and need to be targeted to specific locations. In this paper, we model ...
