Burrow Morphology

Food acquisition in animals that construct burrows for foraging is influenced by burrow structure associated with food distribution and searching patterns. The burrowing patterns of the oriental mole cricket ( Gryllotalpa orientalis Brumeister, 1838) (Orthoptera: Gryllotalpidae) were investigated based on analyses of the relation between burrow morphology and plant distribution. To assess differences between horizontal burrows (HB) with and without vertical burrows (VB), the number of branching points, the length of the horizontal parts, the plant ratio of the burrow area, and the burrow fractal dimension were compared. The size of the burrow area was positively related to the degree of branching. Cyperaceae and Gramineae occurred less frequently, whereas Hydrocotyle sibthorpioide Lam. and areas with no plants were more frequent in the burrow area than in the quadrat area. Juncaceae and Persicaria thunbergii (Siebold and Zucc.) H. Gross ex Nakai occurred more frequently and Lindernia crustacea (L.) F. Muell. occurred less frequently in HB without VB than in HB with VB. The ratio of burrow length to the number of branching points was not significantly different between HB with or without VB. HB with VB had a nearly planar structure (higher burrow fractal dimension) than that of HB alone. HB structure and plant composition of the burrow area differed depending on the presence of VB.

The morphology of burrows constructed by the upogebiid mud shrimps Austinogebia narutensis and Upogebia issaeffi was studied using resin castings of burrows in situ on Mukaishima Island, Seto Inland Sea, Japan, where the two species occurred sympatrically. The burrow structure of both shrimps is a relatively simple Y-shaped pattern, which is typical of the family Upogebiidae. Total burrow length, and length and overall width of the U-shaped section of A. narutensis were greater than those of U. issaeffi, possibly because A. narutensis is the larger species. When the ratios of the burrow measurements to the mean burrow diameter were compared to exclude possible size effects, the burrows of A. narutensis had a wider and shallower U-shaped section than those of U. issaeffi. Because the casts were made where the two species occurred sympatrically, the differences in the burrow morphology were not due to the differences in environmental factors but to the difference in the shrimp species, whether they are adaptive or not.

Abiotic Variables

As part of the Global Observation Research Initiative in Alpine Environments program, the relative contribution of abiotic variables in explaining alpine vegetation was determined for five summits on a spur of Mount Clarke in the Snowy Mountains, Australia. The composition of vascular plant species and life-forms, and topography were determined, and soil nutrients and soil temperature were measured on each aspect of each summit by standardised methods. Ordinations were performed on the composition of vascular plant species and life-forms, topography, soil nutrients and soil temperature-derived variables. Abiotic variables were tested against the biotic dissimilarity matrices to determine which were best correlated with current plant composition. Summits differed in plant composition, with a decrease in the cover of shrubs, and an increase in herbs and graminoids with increasing altitude. Altitude was the main determinant of species composition, accounting for more than 80% of the variation among summits. Soil temperature variables accounted for more than 40% of the variation in composition among summits. Soils were not significantly different among summits, although certain soil variables, principally calcium, were important in predicting plant composition. Because temperature is correlated with current vegetation on these five summits, predicted increased temperatures and decreased snow cover are likely to affect future plant composition in this mountain region.

Burrow Morphology

Since the publication of Baker (2016) three additional burrow casts, unknown to the author, were located in the Natural History Museum, London (NHM) collection by George Beccaloni. These casts were provisionally identified as Gryllotalpa vineae. In order to establish whether this identification was correct a literature survey of the casts of mole crickets (Orthoptera: Gryllotalpidae) was conducted. Through this process a standardised terminology for mole cricket burrows has been established. The application of eccentricity measurements to burrow structures has identified measurements that can potentially be used to discriminate those species for which suitably detailed burrow descriptions have been made available. It is demonstrated that the eccentricity of the restrictions on either side of the bulb, as well as the eccentricity of the horn opening, are useful diagnostic characters.
