“…In the present study, and also in another study 43 , spider species gave specific responses to the environmental gradients created by the forestry treatments. In the Pilis Experiment, the interventions in all treatments induced changes along the main gradients of light level and humidity.…”

To secure the ecosystem services forests provide, it is important to understand how different management practices impact various components of these ecosystems. We aimed to uncover how silvicultural treatments affected the ground-dwelling spider communities during the first five years of a forest ecological experiment. In an oak-hornbeam forest stand, five treatments, belonging to clear-cutting, shelterwood and continuous cover forestry systems, were implemented using randomised complete block design. Spiders were sampled by pitfall traps, and detailed vegetation, soil and microclimate data were collected throughout the experiment. In the treatment plots spider abundance and species richness increased marginally. Species composition changes were more pronounced and treatment specific, initially diverging from the control plots, but becoming more similar again by the fifth year. These changes were correlated mostly to treatment-related light intensity and humidity gradients. The patchy implementation of the treatments induced modest increase in both gamma and beta diversity of spiders in the stand. Overall, spiders gave a prompt and species specific response to treatments that was by the fifth year showing signs of relatively quick recovery to pre-treatment state. At the present fine scale of implementation the magnitude of changes was not different among forestry treatments, irrespective of their severity.

“…In contrast to the fidelity component, the specificity component does not seem to be explained by the sample size. Their high values recorded of this component compared to those of the fidelity agree with what was obtained by Aisen et al (2017), but it differs from what was found by Argañaraz et al (2020aArgañaraz et al ( , 2020b.…”

“…Thus, the smaller the samples or the more dispersed the individuals of a species, the fewer samples they are likely to appear in. In several studies with spiders, when epigean spiders were sampled by pitfall, detector and indicator species were obtained with high values (Gurdebeke et al 2003;Carvalho et al 2011;Ghione et al 2013;Argañaraz et al 2020b;Martínez et al 2022). Probably, those findings are partially related to the long time (two weeks) the pitfall traps were active in those studies, as this increased the probability of a species falling in a larger number of samples.…”

“…With this method, spiders, at the species or family level, have been assessed as indicators of different groups. For example, habitat (Ghione et al 2013;Aisen et al 2017;Quijano-Cuervo et al 2019), habitat in a gradient of disturbance (Kaltsas et al 2014;Argañaraz et al 2020a; van Rensburg et al 2020), management (Torma et al 2019;Argañaraz et al 2020b;Topa et al 2021), succession and restoration (Cristofoli et al 2010;Malumbres-Olarte et al 2013;Yekwayo et al 2019), pollution (Horváth et al 2001;Nahmani et al 2006), soil quality (Nuria et al 2011;Rousseau et al 2013), colonization of agroecosystems (Royauté and Buddle 2012), forest fragmentation and degradation (do Amaral Nogueira and Pintoda-Rocha 2016), seasons (Campuzano and Padilla-Ramírez 2021) and ecosystem services (Elie et al 2018). However, the majority of the research mentioned was carried out in non-South American countries.…”

“…However, the majority of the research mentioned was carried out in non-South American countries. In Argentina, there is an information gap related to this subject as the only studies carried out in this country were those conducted by Aisen et al (2017), Argañaraz et al (2020aArgañaraz et al ( , 2020b, and Martínez et al (2022). Besides, such investigations have been conducted using only soil-dwellers spiders, which are also commonly used in other countries.…”

A��. The spiders of the Salticidae family can be valuable indicators of various environmental conditions because they are distributed over almost all continents and are found in a wide variety of habitats and in all climatic seasons. It was assessed if species of Salticidae function as indicators of the conservation status of habitats and if the use of adult+juvenile or adult-only data yields different results. Spiders were collected in two natural parks and two semi-natural areas located between both parks in an area of Eastern Chaco, Argentina. The samples were taken from three types of habitats: foliage, leaf li�er and grassland. The analysis of indicator species was conducted with the indicator value index (IndVal). A high IndVal value for a species in a habitat (e.g., semi-natural grassland) indicates that it is specific (relatively abundant) and faithful (evenly distributed) to that habitat. The species that presented IndVal values >0.45 and >0.70 were classified as detectors and indicators, respectively. Indicator species are highly characteristic of a group (exclusive or nearly exclusive), while detector species prefer a group, but are not exclusive to it. Philira micans was found to be a detector for the semi-natural foliage; Semiopyla viperina, for the natural leaf li�er and Maeota dorsalis, for the natural grassland. The use of the adult+juvenile dataset provided more information about the number of IndVal-significant species; the three detector species mentioned were detected exclusively from this dataset. This study demonstrates that Salticidae spiders in the studied area are sensitive to the conservation status of the analyzed habitats as detector species were recorded. Besides, this study demonstrates that the adult+juvenile dataset improves the detection of species sensitive to changes.
