The seasonal abundance of Latrodectus katipo Powell, 1871, a declining spider species endemic to coastal dunes in New Zealand, was observed in two different plant communities: an endemic sedge, Ficinia spiralis A. Rich. and an exotic grass, Ammophila arenaria (L.) Link. Using artificial cover objects (ACOs), presence/absence data was collected for L. katipo in the two plant communities. ACOs were positioned at Kaitorete Spit, which supports a healthy population of L. katipo, adjacent to F… 
The prevalence and species richness of spiders associated with marine strandlines on different shore types around Banks Peninsula, New Zealand
Thirty-eight species were recorded in strandlines on Banks Peninsula, New Zealand, with the introduced theridiid Steatoda capensis being the most common and widespread and the New Zealand endemic species Otagoa nova being common.
A history of araneology in New Zealand
ABSTRACT Research on spiders (araneology) in New Zealand has a 180-year history that began just before the Treaty of Waitangi was signed. Initially, specimens were collected and taken back to Europe
Evidence of absence is not proof of absence: the case of the New Brighton katipō
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.
An unexpected journey: the biogeography and conservation ecology of the trapdoor spider genus Cantuaria Hogg, 1902
It is suggested that the manuscript should be rewritten in a chapters-by- chapters format to facilitate more detailed discussion of the author’s motivations and methods.


Population structure and habitat use by the spider Latrodectus katipo along the Manawatu–Wanganui coastline
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 the endangered New Zealand spider, Latrodectus katipo, by artificial cover object.
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.
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,
Use of artificial cover objects for detecting red katipo, Latrodectus katipo Powell (Araneae: Theridiidae)
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.
Processes of Ammophila arenaria (Marram Grass) Invasion and Indigenous Species Displacement, Stewart Island, New Zealand
Abstract The present study (1) describes the rates and patterns of Ammophila arenaria (marram grass) invasion in a large transgressive dune system (Mason Bay) and on a prograding foredune-ridge
Habitat preferences of sub‐montane spiders in northem England
Thirteen study sites were selected to cover the dominant vegetation types on the plateaux of three summits in the North Pennines, England. The spider community of these sites were sampled by pitfall
Ecology of the plant-dwelling spiders (Arachnida: Araneae) of the Erfenis Dam Nature Reserve, South Africa
This study uncovered a rich diversity of plant-dwelling spiders from central South Africa and indicates high similarity and overlap in the fauna of the four grassland types, suggesting that the structural complexity of grasslands has a limited effect on species composition.
The ecology and conservation of Hadramphus tuberculatus (Pascoe 1877) (Coleoptera: Curculionidae: Molytinae)
The critically endangered weevil, Hadramphus tuberculatus, was considered extinct until its rediscovery in 2004 is suggested to be vulnerable and must be carefully managed if extinction is to be avoided.
The conservation status of New Zealand Araneae
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.
Diversity and composition of spider assemblages in five vegetation types of the Terai Conservation Area, India
Comparison of spider diversity and composition in a complex landscape of the Terai Conservation Area characterized by alluvial floodplains of tall grassland interspersed with woodland, swamps, and riparian patches showed that species richness was highest in riparian swamp forest.
