Environmental parameters affecting the concentration of iodine in New Zealand pasture
(American Society of Agronomy, Crop Science Society of America & Soil Science of America, 2019-08-21)
Iodine (I) is an essential trace element commonly deficient in agricultural systems. Whereas there is much information on I in food crops, there is a lacuna of knowledge on the environmental factors that affect pasture I ...
Eutrophication and climate change impacts of a case study of New Zealand beef to the European market
(Elsevier, 2020-03-25)
Objective: Beef production in the Lake Taupō region of New Zealand (NZ) is regulated for nitrogen (N) leaching. The objectives of this study were to 1) evaluate the implications of nitrogen emission limitations on ...
Valuing conservation benefits of disease control in wildlife: A choice experiment approach to bovine tuberculosis management in New Zealand's native forests
(Elsevier, 2017-03-15)
We assess the non-monetary environmental benefits that accrue incidentally in New Zealand (NZ) from pest management conducted primarily to control an animal disease, bovine tuberculosis (TB). TB is an infectious disease ...
Exotic plants accumulate and share herbivores yet dominate communities via rapid growth
(Springer Nature, 2021-05-11)
Herbivores may facilitate or impede exotic plant invasion, depending on their direct and indirect interactions with exotic plants relative to co-occurring natives. However, previous studies investigating direct effects ...
Intensified agriculture favors evolved resistance to biological control
(National Academy of Sciences, 2017-04-11)
Increased regulation of chemical pesticides and rapid evolution of pesticide resistance have increased calls for sustainable pest management. Biological control offers sustainable pest suppression, partly because evolution ...
Resolving an 87-year-old taxonomical curiosity with the description of Psylla frodobagginsi sp. nov. (Hemiptera: Sternorrhyncha: Psyllidae), a second distinct Psylla species on the New Zealand endemic plant kōwhai
(Public Library of Science, 2019-09-18)
A recent DNA-based assessment of the psyllid fauna of New Zealand recorded high genetic variation between populations that were expected to belong to the same psyllid species. Among these, a number of populations of the ...
Using next-generation sequencing to analyse the diet of a highly endangered land snail (Powelliphanta augusta) feeding on endemic earthworms
(Public Library of Science, 2013-09-27)
Predation is often difficult to observe or quantify for species that are rare, very small, aquatic or nocturnal. The assessment of such species’ diet can be conducted using molecular methods that target prey DNA remaining ...
Acizzia errabunda sp. nov. and Ctenarytaina insularis sp. nov.: Descriptions of two new species of psyllids (Hemiptera: Psylloidea) discovered on exotic host plants in New Zealand
(Public Library of Science, 2019-04-10)
A recent molecular-based assessment of the psyllid fauna of New Zealand reported two genetically distinct, undescribed psyllid taxa on host plants not native to that country. Here, a morphological examination confirmed ...
The impact of floral resources and omnivory on a four trophic level food web
(Cambridge University Press, 2008-12-09)
Omnivory is common among arthropods, but little is known about how availability of plant resources and prey affects interactions between species operating at the third and fourth trophic level. We used laboratory and field ...
An annotated checklist of the psyllids of New Zealand (Hemiptera: Psylloidea)
(Magnolia Press, 2016)
A checklist of extant species of Psylloidea in New Zealand is presented. The list is structured according to the latest taxonomic classification of families, subfamilies and genera. It includes 99 species, 71 of which are ...
