Cross Fostering

SummaryWhooping Cranes Grus americana increased from 16 wild migratory birds in 1941 to about 146 birds in 1991. Management on the breeding range in Wood Buffalo National Park, Northwest Territories-Alberta, and protection of the birds along their migration route and on the winter range in Texas, are partly responsible for the population increase. The present Wood Buffalo National Park-Aransas National Wildlife Refuge flock consists of almost 50% non-breeders, mostly subadults. Further increases in the number of breeding pairs beyond the 1991 record of 33 can therefore be expected. The wild population has been a source of surplus eggs, whose removal has not adversely affected population growth. These eggs have been used to establish captive flocks, and captive-reared stock will be used to establish other populations. Attempts to establish a new migratory flock in Idaho by means of cross-fostering Whooping Crane eggs to Sandhill Cranes Grus canadensis have not been completely successful. Present plans call for the establishment of a non-migratory flock in Florida.

The study aimed to assess the long-term population dynamics of questing Rhipicephalus appendiculatus and Rhipicephalus zambeziensis in two landscape zones of the Kruger National Park (KNP). Ticks were collected by dragging the vegetation monthly in three habitats (grassland, woodland and gully) at two sites in the KNP (Nhlowa Road and Skukuza) from August 1988 to March 2002. Larvae were the most commonly collected stage of both species. More R. appendiculatus were collected at Nhlowa Road than at Skukuza, with larvae being most abundant from May to August, while nymphs were most abundant from August to December. Larvae were most commonly collected in the gullies from 1991 to 1994, but in the grassland and woodland habitats from 1998 onwards. Nymphs were most commonly collected in the grassland and woodland. More R. zambeziensis were collected at Skukuza than at Nhlowa Road, with larvae being most abundant from May to September, while nymphs were most abundant from August to November. Larvae and nymphs were most commonly collected in the woodland and gullies and least commonly in the grassland (p < 0.01). The lowest numbers of R. appendiculatus were collected in the mid-1990s after the 1991/1992 drought. Rhipicephalus zambeziensis numbers declined after 1991 and even further after 1998, dropping to their lowest levels during 2002. The changes in numbers of these two species reflected changes in rainfall and the populations of several of their large herbivore hosts, as well as differences in the relative humidity between the two sites over time.

Soil Groups

Exploratory surveys of the Wood Buffalo National Park in Northern Alberta revealed the presence of vast tracts of brunisolic soils. These soils are of common occurrence in the low plains area adjacent to Lake Clare.The brunisolic soils included in this study belong to the Brown Forest, Brown Wooded, and Acid Brown Wooded Great Soil Groups. All profiles were characterized with respect to their physical, chemical, and mineralogical properties. Special attention was directed to the Bf horizons where magnetic, amorphous (to X-ray) humus–iron micropellets were identified with the use of an electron microscope. The release of iron oxide from the weathering of iron-rich chlorites was also evident and is suggested as a mechanism by which the accretion of iron oxide to a pellet form could be explained. The possible genesis of these micropellets is fully discussed.

This checklist of the oribatid fauna of Canada and Alaska (excluding Astigmata) includes 580 identified species in 249 genera and 96 families. The known fauna of Canada includes 556 identified species in 247 genera, and that of Alaska includes 182 species in 95 genera; 39 of the 42 oribatid superfamilies are represented. We further list ~ 300 species that are currently unidentified, and possibly undescribed. In addition, we list 42 genera that are represented only by unidentified and probably undescribed species. For each species we give combinations and synonymies, specific locations in Alaska and the Provinces and Territories of Canada, habitats, and biogeography.                There are 182 identified species known for Alaska, 152 for Yukon, 122 for Northwest Territories, 58 for Nunavut; 210 for British Columbia, 213 for Alberta, 15 for Saskatchewan, 84 for Manitoba, 167 for Ontario, 210 for Québec, 110 for Nova Scotia, 77 for New Brunswick, 84 for Newfoundland and 6 for Prince Edward Island. The known fauna of Canada is smaller than that of Austria, and is approximately equivalent to that of the Czech Republic. As these countries are much smaller in size than Canada and less ecologically diverse, we consider the Canadian and Alaskan fauna are at most 25% known. The paucity of these data reflects the absence of taxonomic and faunistic studies on Oribatida in State, Provinces or Territories, and especially in the Canadian and Alaskan National Park systems and the hundreds of Provincial Parks.                Despite the almost 90% increase in described species since the catalogue of Marshall et al. (1987), there is a need for focussed, coordinated research on Oribatida in the natural regions throughout Canada and Alaska, and for monographs on families and genera with large numbers of undescribed species, such as Brachychthoniidae, Damaeidae, Cepheidae, Liacaridae, Oppiidae, Suctobelbidae, Hydrozetidae, Phenopelopidae, Scheloribatidae, Haplozetidae and Galumnidae.

Based on field reconnaissance since the publication of Flora of the Continental Northwest Territories in 1980, particularly in the District of Keewatin and northeastern District of Mackenzie (Nunavut) and Nahanni National Park, information is provided on geographically significant plant occurrences. One new taxon, Polemonium boreale forma albiflorum, is described, fourteen native taxa are reported as new to the region: Carex hoodii, C. microptera, C. petasata, Corispermum hookeri, C. ochotense, Danthonia spicata, Draba stenoloba, Erysisnum coarctatum, Halenia deflexa, Polygonum fowleri, P. ramosissimum, Salix rotundifolia ssp. rotundifolia, Silene uralensis ssp. ogilviensis, and Vaccinium ovalifolium. Five introduced taxa, Crepis tectorum, Corispermum villosum, Deschampsia elongata, D. incisa var. incisa, and Medicago sativa ssp. falcata are new to the flora of the region. Two native taxa, Danthonia intermedia and Potentilla porsildiorum are deleted from the flora and Ranunculus aquatilis var hispidulus is placed in synonymy. Significant range extensions for 125 native and one introduced taxon are included.

Macropus Rufus

Between July 1979 and November 1980 a total of 261 red kangaroos, Macropus rufus, (216F; 45 M) and 170 western grey kangaroos, M. fuliginosus, (136F;34M) were caught and tagged with individually recognisable collars. Between July 1979 and January 1986, 1751 sightings of tagged individuals were recorded. Information gained from these sightings was used to assess how far each kangaroo ranged. More than 90% of individuals of either species did not range far (<9 km for reds; <6 km for western greys) even when local pastures were severely depleted during drought. A few individuals dispersed much further-up to 323 km. On average, red kangaroos ranged further than western greys. Kangaroos on Kinchega National Park ranged no less or no further than those on an adjacent pastoral leasehold. At least 17 tagged individuals crossed the macropod-deterrent fence surrounding Kinchega; several crossed repeatedly. Dispersal of kangaroos from Kinchega was slight, supporting the hypothesis of Bayliss (1985) that dispersal has no significant impact on population dynamics.
