“…Spiders are one of the most ubiquitous and diverse taxa in terrestrial ecosystems (Coddington & Levi, 1991). These arthropods are useful for understanding how dispersal and habitat interact (Florencio et al, 2016; Gavish & Ziv, 2016; Malumbres‐Olarte et al, 2014), and in the field of insular biogeography, they are providing evidence of how isolation, mobility and microhabitat size affect the functionality of species and assemblages (Méndez‐Castro et al, 2020) as well as colonisation and vicariance processes across archipelagos (Čandek et al, 2019; Gillespie, 2002; Rominger et al, 2015). Furthermore, spiders can be used to understand the effects of dispersal, between‐habitat differences and disturbance on the SADs of assemblages, providing useful information for conservation management (Boieiro et al, 2018; Borges et al, 2008; Cattin et al, 2003; Kaltsas et al, 2019; Kondratyeva et al, 2019; Leroy et al, 2014; Morel et al, 2019).…”

Aim Habitat diversity has been linked to the diversity and structure of island communities, however, little is known about patterns and processes within habitats. Here we aim to determine the contributions of habitat type and inferred dispersal frequency to the differences in taxonomic structure between assemblages in the same island habitat. Location The Macaronesian archipelagos (Azores, Madeira, the Canary Islands and Cabo Verde). Taxon Spiders (Araneae). Methods We established forest and dry habitat sites (each with five plots) on two islands per archipelago. We collected spiders using standardised sampling protocols. We tested the differences in beta diversity separately for each habitat and for each inferred category of ballooning (an aerial dispersal strategy) frequency across geographic scales through nested non‐parametric permutational multivariate analyses of variance. We then tested whether ballooning and habitat influenced heterogeneity in species composition (dispersion in beta diversity) in the two habitat types. We analysed the effects of habitat and ballooning on species abundance distribution (SAD) and rarity by fitting Gambin models and evaluating the contribution of ballooning categories to SAD. Results Communities of the same archipelago and habitat were taxonomically more similar, and beta diversity increased with geographic scale, being greater in dry habitats. There was greater species replacement among assemblages in dry habitats than in forests, with greater differences for rare ballooners. There were no differences in SAD between habitats although dry habitat sites seemed to harbour more species with low abundances (rare species) than forests. Main conclusions Habitat type does not only condition the differences between spider assemblages of the same habitat but also the scale at which they occur. These differences may be determined by the heterogeneity in the physical structure of each habitat as well as how much this structure facilitates aerial dispersal (ballooning), and should be considered in theories/hypotheses on island community assembly as well as in conservation strategies.

“…Invasions of alien spiders on the Neotropical Region are yet poor studied. Most of the available papers are descriptive (Carvalho et al, 2007;Almeida-Silva & Brescovit, 2008;Ott & Brescovit, 2013;Pompozzi et al, 2013;Ruiz & Bonaldo, 2013;Taucare-Ríos & Bustamante, 2015) and just a few deals with the relations of the studied species with their environments (Malumbres-Olarte, 2015;Rodríguez-Rodríguez et al, 2015). Nevertheless, the handful studies carried on in Brazil have been showing a large number of invasive or synanthropic spiders and the list of those spiders in Brazilian territory depicts today at least fifty species (Brescovit, 2002;Indicatti & Brescovit, 2008;Simó et al, 2015).…”

Twelve non-native species of the spider family Oonopidae are recorded in Brazil: Brignolia dasysterna Platnick, Dupérré, Ott & Kranz-Baltensperger, 2011, B. parumpunctata (Simon, 1893), Triaeris stenaspis Simon, 1892, Ischnothyreus peltifer (Simon, 1892), I. velox Jackson, 1908, Opopaea concolor (Blackwall, 1859), O. deserticola Simon, 1892, Pelicinus marmoratus Simon, 1892, Heteroonops spinimanus (Simon, 1892), Gamasomorpha parmata (Thorell, 1890) (herein restored to its original combination in Xestaspis), Orchestina pavesiiformis Saaristo, 2007 and O. dentifera (Simon, 1893). Among these species, six new synonyms were detected: Hytanis oblonga Simon, 1893, Xestaspis bipeltis Thorell, 1895, Gamasomorpha insularis Simon, 1907 and Opopaea lutzi Petrunkevitch, 1929 with Xestaspis parmata Thorell, 1890; Gammasomorpha humilis Mello-Leitão, 1920 with Opopaea concolor (Blackwall, 1859) and Gamasomorpha rufa Banks, 1898 with Opopaea deserticola Simon, 1891. Since Hytanis oblonga is the type species of the genus, its synonymy with Xestaspis parmata imply in the synonymy of Hytanis Simon, 1893 with Xestaspis Simon, 1884. The partenogenetic species T. stenaspis is the most distributed synanthropic oonopid in Brazil, occurring all over the country, mainly in urban areas. Some species are reported here to occur in the interior of natural caves, a finding that should raise conservation concerns.

“…Previous studies, at the local scale, have detected associations between response to fire and species-level traits. For example, Malumbres-Olarte et al [66] found that ambushing, stalking and sheet web building spiders were associated with unburned sites in New Zealand grasslands. Another study in an Australian desert ecosystem found that recently burned sites had a higher abundance of individuals with large body size, limited dispersal ability, burrowing habit and ambush hunting strategies, but that patterns were not consistent across post-fire ages [14].…”

“…Similarly, the abundance of linyphiids (dwarf spiders) was initially lower in the fire treatment but increased over time after fire. Linyphiids have previously been found to be effective colonisers of burned areas [62]. Conversely, spiders of the family Agelenidae (funnel weavers) decreased in abundance over time since fire.…”

Fire is an important ecological disturbance; however, in many regions fire regimes are changing due to anthropogenic factors. Understanding the responses of species and ecosystem to fire can help to develop predictive models and inform fire management decisions. Despite their massive diversity and abundance, relatively little is known about the impacts of fire on invertebrates. Spiders are a diverse and ubiquitous group, with variation in ecological, behavioural and life history traits, and can offer important insights into the impacts of fire on invertebrates and whether these depend on environmental factors, phylogenetic history, or species traits. We conducted phylogenetic comparative analyses of published data from studies investigating the impacts of fire on spiders. We investigated whether fire affects family level abundance and whether this effect depends on ecologically relevant traits or site-specific factors (vegetation, latitude, fire type, time since fire). We found that time since fire had a significant effect on the abundance of some spider families (Lycosidae, Linyphiidae, Agelenidae), and within forest vegetation types. There was no relationship between family level traits and response to fire, suggesting that a trait-based approach does not increase predictive power in this group at this taxonomic level. Overall, it is difficult to make broad generalisations about the impacts of fire on spider abundance due to variation in site- and fire-specific factors. We did, however, find evidence that short fire intervals may be a threat to some spider families, and in forest ecosystems, where abundance initially decreased after fire, which may have important implications for fire management strategies. Finally, we show that analyses of published data can be used to detect broad scale ecological patterns and provide an alternative to traditional meta-analytical approaches.
