“…Although L. hasselti spiders can tolerate a wide range of temperatures, their growth may be slowed and egg sacs may cease development at low temperatures [ 70 ]. Matsuse et al [ 68 ] reported that the greatest survival rate of the spiders was at 20 °C; if under 5–10 °C, they could survive for a month but did not grow or moult. Juvenile spiders can survive short exposure (20 min) to freezing temperatures, however, the developmental zero of the egg sacs (i.e., the temperature at which egg sac development ceases) is 15–18 °C and the spiderlings do not emerge at 20 °C [ 68 , 69 ].…”

In addition to these effects of temperature, L. hasselti are adapted to xeric conditions, so may not be able to survive in areas with high precipitation or humidity [ 61 ].…”

“…Searches for records were also carried out in Google Scholar for localities of the species in published literature. A total of 2580 raw occurrence records (GPS localities) of L. hasselti were collected from the GBIF and literature [ 66 , 68 , 73 ] for the study area. We compiled these location points into two subsets: native occurrences (Australia; 1967 localities) and invasive occurrences (other countries; 613 localities).…”

Realized niche shift of an invasive widow spider: drivers and impacts of human activities

et al. 2022

Background Predicting invasiveness requires an understanding of the propensity of a given species to thrive in areas with novel ecological challenges. Evaluation of realized niche shift of an invasive species in its invasive range, detecting the main drivers of the realized niche shift, and predicting the potential distribution of the species can provide important information for the management of populations of invasive species and the conservation of biodiversity. The Australian redback spider, Latrodectus hasselti, is a widow spider that is native to Australia and established in Japan, New Zealand, and Southeast Asia. We used ecological niche models and ordinal comparisons in an integrative method to compare the realized niches of native and invasive populations of this spider species. We also assessed the impact of several climatic predictor variables and human activity on this niche shift. We hypothesized that human impact is important for successful establishment of this anthropophilic species, and that climatic predictor variables may determine suitable habitat and thus predict invasive ranges. Results Our models showed that L. hasselti distributions are positively influenced by human impact in both of the native and invasive ranges. Maximum temperature was the most important climatic variable in predictions of the distribution of native populations, while precipitation seasonality was the most important in predictions of invasive populations. The realized niche of L. hasselti in its invasive range differed from that in its native range, indicating possible realized niche shift. Conclusions We infer that a preference for human-disturbed environments may underlie invasion and establishment in this spider species, as anthropogenic habitat modifications could provide shelters from unsuitable climatic conditions and extreme climatic stresses to the spiders. Because Australia and the countries in which the species is invasive have differing climates, differences in the availability of certain climatic conditions could have played a role in the realized niche shift of L. hasselti.

“…Redback spiders can tolerate very low temperatures b Fig. 2 Cluster analysis in the CCBNR showing areas of clustering above 90, 95 and 99% confidence intervals for redback spider locations (Kamimura et al 1998) but they need shelter from extreme weather (Matsuse et al 1999) and rain and high soil moisture (Vink et al 2011). Shelter is an important factor determining their distribution in agricultural and urban landscapes in Japan (Nihei et al 2004).…”

“…Redback spiders have features typical of successful invaders: they are generalist predators, able to survive long periods without food (Vink et al 2011), they can survive cold temperatures (Nihei et al 2004), females can store sperm for several years (Biosecurity NZ 2007), offspring can successfully interbreed (Forster 1984in Vink et al 2011, and female spiders produce a large number of offspring (Biosecurity NZ 2007). They are often associated with humans, typically building webs in anthropogenic environments (Matsuse et al 1999) because human structures provide them with protection from extreme weather conditions (Vink et al 2011;Biosecurity NZ 2007). It is likely that redback spiders reached New Zealand through international trade (Vink et al 2011) in shipments of steel, in vehicles, and in fresh produce and other goods (Biosecurity NZ 2007).…”

Synergy between two invasive species, redback spiders and rabbits, threaten the endangered Cromwell chafer beetle

et al. 2017

Interactions between invasive species can be difficult to predict and can result in unanticipated impacts of significance for native fauna. Here we show that introduced European rabbits (Oryctolagus cuniculus) create habitat that enables invasive redback spiders (Latrodectus hasselti Thorell, 1870) to establish and prey upon the nationally endangered, endemic Cromwell chafer beetle (Prodontria lewisii Broun, 1904). We examined the spatial relationship between rabbit holes and redback spider occurrence, recorded all prey caught in redback spider webs over a 4-month period, and tested the role rabbit holes play in providing habitat for redback spiders experimentally, by filling in rabbit holes in areas used by spiders and monitoring subsequent occupation of the areas over four months. Redback spiders predominately resided in old rabbit holes, with the highest densities of spiders coinciding with high densities of rabbit holes. Cromwell chafer beetles were commonly caught in webs. Filling in rabbit holes eliminated the presence of redback spiders at all treated sites and reduced prey capture in those areas. Conservation management to protect Cromwell chafer beetles should focus on eliminating rabbits and their holes from beetle habitat.
