Abstract The competitive interactions between Latrodectus katipo and Steatoda capensis were studied under the hypothesis that L. katipo is being displaced from its natural habitat by competition from S. capensis. Use of trophic and spatial resources were studied. High overlap for both resources was found. Data on reproductive potential revealed that S. capenisis has a significantly higher reproductive output. Laboratory predation experiments indicated L. katipo adults are not inferior to S… 

Population structure and habitat use by the spider Latrodectus katipo along the Manawatu–Wanganui coastline

TLDR
It is concluded that katipo populations along the Manawatu–Wanganui coastline are threatened by a range of human activities, and that management action may be required to prevent local extinctions of this charismatic invertebrate.

Species status and conservation issues of New Zealand’s endemic Latrodectus spider species (Araneae : Theridiidae)

TLDR
The species status of the Latrodectus spiders of New Zealand was assessed using molecular and morphological methods and with cross-breeding experiments and it is concluded that L. atritus is a junior synonym of L. katipo.

Descriptions of four Steatoda species (Araneae, Theridiidae) found in New Zealand

TLDR
Theridium truncatum Urquhart, 1887 is recognised as a valid species within Steatoda, and the male is described here for the first time.

The conservation status of New Zealand Araneae

TLDR
Since the last listing of Threatened spiders the number of species categorised as Threatened and At Risk has increased slightly whereas the number categorising as Data Deficient has been reduced by 309 taxa.

The ecology and conservation of Latrodectus katipo, New Zealand's endangered widow spider

New Zealand has two endemic widow spider species; Latrodectus katipo Powell , 1871 and L. atritus Urquhart 1890. This study focused on the population dynamics and habitat usage of L. katipo , which

Spatial associations between invasive tree lupin and populations of two katipo spiders at Kaitorete Spit, New Zealand.

TLDR
Spatial associations between the invasive tree lupin, the New Zealand endemic widow spider Latrodectus katipo (katipo), and the introduced South African spider Steatoda capensis were examined within the nationally significant Kaitorete Spit dune system in Canterbury, New Zealand.

Population monitoring of the endangered New Zealand spider, Latrodectus katipo, by artificial cover object.

TLDR
Latrodectus katipo populations were found to have highly female biased sex-ratios, with a longer breeding season at Himatangi than reported previously at other sites, and ACOs could be used as a non-destructive monitoring tool for many other invertebrate species.

Four new species of the genus Pseudocellus (Arachnida: Ricinulei: Ricinoididae) from Mexico

TLDR
The number of known species in the genus increases to 24, and Mexican species to 14, and an identification key for adult males of the species found in Mexico and southern USA is provided.

Spatial Niche Separation on the Periphery Range of Argiope bruennichi and Its Effect With Araneus quadratus (Araneae: Araneidae)

TLDR
The results indicate that A. bruennichi does not exert a significant negative impact on A. quadratus web placement, which indicates that the two species clearly prefer different heights, which in turn may determine the kind of prey they catch.

Population monitoring of Latrodectus katipo Population monitoring of the endangered New Zealand spider , Latrodectus katipo , with artificial cover objects

The endangered New Zealand widow spider, Latrodectus katipo, is believed to have undergone marked population decline over the last 30 years, but as monitoring methods are timeand labour-intensive,

Evidence for displacement of a North American spider, Steatoda borealis (Hentz), by the European species S. bipunctata (Linnaeus) (Araneae: Theridiidae)

TLDR
Evidence indicates that S. bipunctata, which closely resembles the native S. borealis in size, colour, microhabitat, diel activity, prey selection and utilization, life history, and sexual behaviour, can displace S. Borealis.

THE HABITAT AND DISTRIBUTION OF THE KATIPO SPIDER AT SOUTH BRIGHTON BEACH, CHRISTCHURCH, NEW ZEALAND

TLDR
An analysis of the contents of 32 webs indicated that a weevil, Cecyropa modesta, is probably the most important prey of the Katipo spider.

The Experimental Analysis of Competition between Two Syntopic Species of Orb-Web Spiders (Araneae: Araneidae)

TLDR
Observed field experiments in 1979 and 1980 provide indirect evidence of the importance of physical factors and possibly vegetation in the distribution and abundance of A. au- rantia and A. trifasciata.

A new combination involving Lithyphantes lepidus Cambridge 1897 and a new name for Teutana lepida Cambridge 1903 (Araneae, Theridiidae)

TLDR
The name Steatoda capensis nomen novum is provided to replace Teutana lepida Cambridge and recognises the origin of the spider, that is Cape Town, South Africa.

Coexistence in a Guild of Wandering Spiders

TLDR
The spider fauna of soil and litter may be separated into several distinct groups, based on the methods used in prey capture, and the spatial and seasonal distribution of foraging activity in the wandering spider guild was studied by pitfall trapping.

PATTERNS OF RESOURCE USE AND TESTS FOR COMPETITIVE RELEASE IN A SPIDER COMMUNITY

TLDR
Investigation of the degree to which various resources were in limited supply to these species during the course of the study indicates that space was a potentially limiting factor, while prey availability appeared to be in excess of the needs of the populations.

Competition Between Two Spider, Species: Experimental Field Study

TLDR
It is suggested that the abundance of predators of spiders was low at this study site because of physical constraints and Predators or abiotic sources of mortality may have been reducing the spider populations during these other studies, reducing competition.

PATTERNS OF CO-EXISTENCE IN A GUILD OF RAPTORIAL SPIDERS

TLDR
Patterns of co-existence among five syntopic species of raptorial spiders were investigated and mean body size ratios were less than the co- existence value.

Thermal Balance and Prey Availability: Bases for a Model Relating Web‐Site Characteristics to Spider Reproductive Success

Analyses of the movements and web-site characteristics of the desert spider Agelenopsis aperta (Gertsch) demonstrate that web locations offering the following habitat features are actively selected:

Segregation and Symmetry in Two-Species Populations as Studied by Nearest- Neighbour Relationships

TLDR
The degree to which the individuals in a two-species population are 'mingled together' is clearly an intrinsic property of the whole population, and one independent of scale, and it is possible to measure this property in such a way that the result obtained is independent of any arbitrary characteristic of the sampling method.
