Additionally, habitat loss and fragmentation due to human activities such as land clearing, urbanization, and agriculture have placed significant pressure on kangaroo populations. In recent years, there has been increasing interest in the conservation and management of kangaroo populations. Many ...
Evaluates the consequences of habitat fragmentations for kangaroo rats by assessing their movements using live-trapping and radiotelemetry. Movements based on captures; Movements based on radiotelemetry; Median distance and distances moved; Frequency distribution of maximum dispersal distances; Frequency of ...
San Bernardino kangaroo rat ( Dipodomys merriami parvus ; SBKR), an endangered subspecies, faces ongoing anthropogenic threats such as habitat loss. Their habitat has undergone strong human-mediated fragmentation, resulting in extinction of some local populations and dramatic size reduction of the ...
Molecular dating and ancestral habitat reconstruction was carried out with MrBayes 3.2.637. The analyses employed the five nuclear gene (Rag1, BRCA1, vWF, IRBP, ApoB) data matrix of Meredithet al.3for 31 macropods (Macropodiformes), and seven outgroup species, with temporal calibration from...
We also apply molecular clock calibrated ancestral range estimations to infer both the timing and context of macropodoid habitat change over the last ~ 25 Ma. Materials and methods Samples and sequencing. We obtained non-formalin-fixed liver samples from a male Caloprymnus campestris ...
Habitat fragmentationHabitat lossLumholtz's tree-kangarooTropical rainforestA key challenge for wildlife biologists is to predict how fauna will respond to habitat loss. During an ongoing study of habitat use by Lumholtz's tree-kangaroos (Dendrolagus lumholtzi), an unexpected opportunity arose to ...
Increased availability of anthropogenic resources or fragmentation acting as a barrier to transmission may be physical factors influencing prevalence. Alterations to plant cover or intermediate host abundance may be biological factors and there may be behavioral differences in kangaroo rat populations between...
Though degradation such as fragmentation and loss of habitat have played important roles, changes in vegetation patterns at sites in Wichita County may also be important. Much historic range of the Texas kangaroo rat has been fragmented by extensive cultivation within the Rolling Plains Region of ...
