Detection dog efficacy for collecting faecal samples from the critically endangered Cross River gorilla (Gorilla gorilla diehli) for genetic censusing
Population estimates using genetic capture-recapture methods from non-invasively collected wildlife samples are more accurate and precise than those obtained from traditional methods when detection and resampling rates are high. Recently, detection dogs have been increasingly used to find elusive species and their by-products. Here we compared the effectiveness of dog- and human-directed search...
متن کاملFracture toughness of mountain gorilla (Gorilla gorilla beringei) food plants.
Mountain gorillas, the largest extant primates, subsist almost entirely on plant matter. Moreover, their diet includes a substantial amount of structural material, such as bark and stems, which other primates tend to avoid. Accordingly, the robust masticatory apparatus of gorillas may be adaptive to this presumably tough diet; however, quantitative information on this subject is lacking. In thi...
متن کاملGenetic analysis reveals population structure and recent migration within the highly fragmented range of the Cross River gorilla (Gorilla gorilla diehli).
Recently developed methods of individual-based analysis of genetic data allow an unprecedented opportunity to understand the relationships among fragmented populations. By defining population structure and identifying migrant individuals, such analyses can provide a framework to aid in evaluating the threats posed by inbreeding and reduced genetic variability as a consequence of limited gene fl...
متن کاملEffectiveness of Technology Dissemination and Adoption among Farmers in Cross-River State, Nigeria
This study compared farmers’ rating of extension effectiveness in technology dissemination to the level of adoption. In conducting the study, 180 farmers participating in extension programme in Cross-River State were randomly selected through multi-stage random sampling technique. The data collected through a structured questionnaire were analyzed using the t-test of significance of difference ...
متن کاملEffects of habitat fragmentation, population size and demographic history on genetic diversity: the Cross River gorilla in a comparative context.
In small and fragmented populations, genetic diversity may be reduced owing to increased levels of drift and inbreeding. This reduced diversity is often associated with decreased fitness and a higher threat of extinction. However, it is difficult to determine when a population has low diversity except in a comparative context. We assessed genetic variability in the critically endangered Cross R...
