Spatial associations between the invasive tree lupin (Lupinus arboreus), the New Zealand endemic widow spider Latrodectus katipo (katipo), and the introduced South African spider Steatoda capensis (false katipo) were examined within the nationally significant Kaitorete Spit dune system in Canterbury, New Zealand. These dunes are considered to be a stronghold for L. katipo, but with the decline in preferred vegetation for capture-web attachment as a result of tree lupin invasion, a decline in… 

Figures and Tables from this paper

Evidence of absence is not proof of absence: the case of the New Brighton katipō
TLDR
The results emphasise that sampling models that use non-detection to indicate the likelihood of species absence can be highly specific to the sampling method used.
Short-term soil nutrient and plant community responses to the eradication of a nitrogen fixing tree, Lupinus arboreus
TLDR
The application of herbicide resulted in the slow decay of the mature plant and as such delayed an increase in exotic species cover and inhibited L. arboreus germination, a legacy effect which will hinder restoration of the original structure and function in the long term.

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.
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,
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.
Use of artificial cover objects for detecting red katipo, Latrodectus katipo Powell (Araneae: Theridiidae)
TLDR
Although red katipo appear to have declined in number and distribution, the scarcity of detailed historical records and lack of a nationallyimplemented standard survey methodology mean that current rates of population declines and range reductions are difficult to determine.
Evidence for the displacement of an endemic New Zealand spider, Latrodectus katipo powell by the South African species Steatoda capensis Hann (Araneae : Theridiidae)
TLDR
Differences in reproductive potential and seasonal reproduction are proposed as the mechanism underlying the displacement of L. katipo from its natural habitat by competition from S. capensis.
Decline of tree lupin (Lupinus arboreus) on Kaitorete Spit, Canterbury, New Zealand, 1984-1990
TLDR
The decline of a large stand of tree lupin at Kaitorete Spit was observed between December 1984 and May 1990 and it is considered that the plant has an uncertain future within the area.
The little fire ant Wasmanniaauropunctata: a new invasive species in the Middle East and its impact on the local arthropod fauna
TLDR
It is shown here that this tropical species can pose a critical threat to local arthropods at a wider range of climatic conditions than was previously known.
BLIGHT OF LUPINUS ARBOREUS IN NEW ZEALAND
TLDR
A 4-year programme monitoring the effect of the disease on lupin populations has demonstrated that both longevity of plants and production of seed have been reduced since the blight was first recognised.
