Long‐term patterns of invertebrate abundance and relationships to environmental factors in arid Australia

et al. 2016

Resource pulses are a key feature of semi-arid and arid ecosystems and are generally triggered by rainfall. While rainfall is an acknowledged driver of the abundance and distribution of larger animals, little is known about how invertebrate communities respond to rain events or to vegetative productivity. Here we investigate Ordinal-level patterns and drivers of ground-dwelling invertebrate abundance across 6 years of sampling in the Simpson Desert, central Australia. Between February 1999 and February 2005, a total of 174 381 invertebrates were sampled from 32 Orders. Ants were the most abundant taxon, comprising 83% of all invertebrates captured, while Collembola at 10.3% of total captures were a distant second over this period. Temporal patterns of the six invertebrate taxa specifically analysed (Acarina, ants, Araneae, Coleoptera, Collembola and Thysanura) were dynamic over the sampling period, and patterns of abundance were taxon-specific. Analyses indicate that all six taxa showed a positive relationship with the cover of non-Triodia vegetation. Other indicators of vegetative productivity (seeding and flowering) also showed positive relationships with certain taxa. Although the influence of rainfall was taxon-dependent, no taxon was affected by short-term rainfall (up to 18 days prior to survey). The abundance of Acarina, ants, and Coleoptera increased with greater long-term rainfall (up to 18 months prior to survey), whilst Araneae showed the opposite effect. Temperature and dune zone (dune crest vs. swale) also had taxon-specific effects. These results show that invertebrates in arid ecosystems are influenced by a variety of abiotic factors, at multiple scales, and that responses to rainfall are not as strong or as predictable as those seen for other taxa. Our results highlight the diversity of invertebrates in our study region and emphasize the need for targeted long-term sampling to enhance our understanding of the ecology of these taxa and the role they play in arid ecosystems.

“…Invertebrates were identified to Order, except for spiders (Order Arachnida) and bees, wasps and ants (Order Hymenoptera) which were identified to Family using identification keys [ 60 , 61 ]. Invertebrates were identified to these levels as knowledge of finer-scale taxonomy for many arthropods in the study region is lacking [ 62 , 63 ]; therefore, confident species- and genus-level identification for many taxa was not feasible [ 37 ].…”

Assessing the potential for intraguild predation among taxonomically disparate micro-carnivores: marsupials and arthropods

2018

Interspecific competition may occur when resources are limited, and is often most intense between animals in the same ecological guild. Intraguild predation (IGP) is a distinctive form of interference competition, where a dominant predator selectively kills subordinate rivals to gain increased access to resources. However, before IGP can be identified, organisms must be confirmed as members of the same guild and occur together in space and time. The lesser hairy-footed dunnart (Sminthopsis youngsoni, Dasyuridae) is a generalist marsupial insectivore in arid Australia, but consumes wolf spiders (Lycosa spp., Lycosidae) disproportionately often relative to their availability. Here, we test the hypothesis that this disproportionate predation is a product of frequent encounter rates between the interactants due to high overlap in their diets and use of space and time. Diet and prey availability were determined using direct observations and invertebrate pitfall trapping, microhabitat use by tracking individuals of both species-groups, and temporal activity using spotlighting and camera traps. Major overlap (greater than 75% similarity) was found in diet and temporal activity, and weaker overlap in microhabitat use. Taken together, these findings suggest reasonable potential, for the first time, for competition and intraguild predation to occur between taxa as disparate as marsupials and spiders.

“…The hair on the hind tibia of L. glendae is relatively sparse, more like that of L. (Protomorpha) gurneyi than the denser, more highly branched hair of L. (Protomorpha) gibber. The sparser scopal hair of the former species was ascribed to preferential collection of pollen tetrads from Lechenaultia divaricata rather than from Scaevola species (Batley & Popic, 2013). No Lechenaultia flowers were found when the L. glendae specimens were collected.…”

aBstract. Leioproctus glendae Batley, n. sp., is described on the basis of two males and one female from western Queensland. The female has an unusually narrow fore basitarsus and mandibular structure not seen in other members of the genus, while the male terminalia do not closely resemble those of any other species group. The new species provides further demonstration of the variety of forms contained in the genus Leioproctus, and is described in order to assist future revision of this group.
