“…It was estimated that the total observed species richness represented 74-80% of the true epigeal spider fauna present at the sites. This is similar to the range seen in other spider and invertebrate community studies in New Zealand for which data are available (Affeld et al 2009;Ward et al 2014;Lamont et al 2017). The species deficit is due to the prevalence of species caught in very low numbers, in particular singletons (19%) and doubletons (12%), relative to the more common species.…”

“…The fact that spiders respond to changing environmental conditions means they can also be used as indicators of various habitat characteristics, including seral stage (Wise 1993;Willett 2001;Gerlach et al 2013). Spiders have been included in some studies of biodiversity in indigenous ecosystems in New Zealand (Berndt 1998;Alley et al 2001;Derraik et al 2001;Sinclair et al 2005;Michel et al 2008;Affeld et al 2009;Lamont et al 2017), though few of the studies have investigated detailed environmental predictors of those communities (but see Hodge et al 2007;Malumbres-Olarte et al 2013a, 2013b.…”

Te Paki Ecological District (TPED) in northern Northland, New Zealand, is well known as an ecologically significant centre of endemism. However, due to extensive anthropogenic habitat degradation, native forest has been reduced to small, isolated remnants and many of its endemic species are threatened with extinction. Epigeal spider communities (species living on or near the ground) were surveyed within TPED by pitfall trapping at seven native forest remnants differing in plant composition and apparent seral stage to investigate how spider communities varied within them. Surveys were conducted four times over a 12-month period coinciding with winter, spring, summer and autumn. Changes in spider communities were related to differences in plant composition, which were in turn associated with differences in apparent seral stage of the vegetation. Spider communities in forests at later seral stages were dominated by species such as Rinawa sp., Porrhothele sp. and Uliodon sp., whereas Euryopis nana, Cambridgea reinga, Stanwellia hollowayi and Hypodrassodes apicus were most prevalent in remnants at earlier seral stages. These species could potentially serve as useful bioindicators of ecological succession or restoration. Apart from soil organic matter content none of the predictor variables tested, including plant species richness, were significantly correlated with spider richness or diversity. Spider richness and diversity are most likely determined by a complex interaction of environmental and temporal factors that operate at different spatial scales. This study has increased our understanding of the ecological associations of spider communities and established that TPED is an important centre of endemism for spiders in New Zealand. We have also demonstrated the importance of forest remnants as reservoirs of indigenous spider diversity and helped resolve several historical taxonomic issues. Furthermore, we demonstrate the need for taxonomic research in this region of New Zealand and highlight the value of such biodiversity surveys.

“…Em eucalipto, mesma família da cagaiteira, já foram previamente registradas as espécies de tripes Selenothrips rubrocinctus Giard, Retithrips syriacus Mayet e Thrips australis Bagnall (MONTEIRO; MOUND; ZUCCHI, 1999;2001). Affeld et al (2010) relataram a ocorrência de três famílias de tripes (Merothripidae, Phlaeothripidae e Thripidae) em Metrosideros robusta (Myrtaceae).

Eugenia dysenterica é uma espécie nativa do Cerrado com potencial para exploração econômica em função do seu uso na alimentação. No entanto, estudos são necessários para possibilitar a domesticação da espécie em plantio comercial. Atualmente, os frutos são obtidos a partir do extrativismo em áreas do Bioma Cerrado. A artropodofauna associada à Eugenia dysenterica é praticamente desconhecida. Assim, o presente estudo teve como objetivo avaliar a artropodofauna associada às folhas de Eugenia dysenterica. Avaliamos quinzenalmente a artropodofauna em plantas de Eugenia dysenterica na coleção de germoplasma ex situ da Escola de Agronomia, UFG. Para tanto, três ramos do terço médio foram amostrados em 16 plantas. Posteriormente, sete folhas/ramo foram selecionadas e analisadas sob microscópio estereoscópio. As cochonilhas foram os artrópodes mais abundantes em Eugenia dysenterica. A presença de folhas novas no mês de outubro coincidiu com a eclosão das ninfas da cochonilha Ceroplastes acutus e com o aparecimento de galhas foliares causadas por dípteros. A superfamília Coccoidea e a família Aleyrodidae foram classificadas como superabundantes e superfrequentes. Duas famílias de Thysanoptera foram encontradas: Thripidae e Phlaeothripidae. Com relação aos ácaros, as espécies fitófagas foram as mais abundantes, seguidas pelos ácaros predadores. As famílias Phytoseiidae e Tenuipalpidae foram as mais representativas nas amostras. Aleirodídeos, dípteros e a cochonilha Ceroplastes acutus estão associados à emissão de novas folhas da cagaiteira. Este é o primeiro relato de ocorrência de espécies de ácaros, tripes e da cochonilha Ceroplastes acutus em Eugenia dysenterica.

“…All species are woody and include climbers, small shrubs and trees, and emergent trees. The family provides resources for a wide array of organisms, including fungi, insects, birds, and mammals (Lindenmayer et al, 1991; McKenzie et al, 1999; Pizo, 2002; Affeld et al, 2009). It includes many species with cultural and economic importance (Abbott, 1992; Teulon et al, 2015).…”

Aims The Myrtaceae is a woody family that plays an important role in forest ecosystems globally. The recent spread of myrtle rust, caused by a fungal pathogen (Austropuccinia psidii), from its native South America into New Zealand (NZ), highlights the need to quantify the ecological importance of Myrtaceae in NZ woody ecosystems. Location New Zealand. Methods Using NZ nationwide forest and shrubland inventory data, collected from 2009 to 2014, we quantified the ecological importance of Myrtaceae based on its richness and abundance relative to co‐occurring woody families. We then explored how climate and forest stand structure affect Myrtaceae importance in general and by tribe and growth form. Finally, we compared functional traits associated with plant growth and reproductive strategies with other dominant woody families and determined Myrtaceae's contributions to community‐weighted mean (CWM) trait values. Results Myrtaceae occurred in 74% of the study plots and its importance value was the second highest across the woody families. It was the only one in which climbers substantially contributed to the importance value (17%). Greater Myrtaceae importance values were associated with warmer and more mesic climates and early forest successional stages. Climate associations were similar within tribes and growth forms, whereas forest structure effects varied. Myrtaceae was functionally distinct from most co‐occurring woody families. Contributions to CWM wood density, maximum height, and specific leaf area values were significantly greater than expected from its importance value. Conclusions Myrtaceae is the second most ecologically important woody family in NZ woody ecosystems. The family has a distinctive functional trait spectrum associated with high wood density and tall stature, ensuring large and enduring carbon stocks. There will potentially be large and deleterious outcomes in forest ecosystems if taxon‐specific pathogens, such as Austropuccinia psidii, spread and significantly reduce Myrtaceae importance.
