Genetic connectivity and population structure of African savanna elephants (Loxodonta africana) in Tanzania

Increasing human population growth, exurban development, and associated habitat fragmentation is accelerating the isolation of many natural areas and wildlife populations across the planet. In Tanzania, rapid and ongoing habitat conversion to agriculture has severed many of the country’s former wildlife corridors between protected areas. To identify historically linked protected areas, we investigated the genetic structure and gene flow of African savanna elephants in Tanzania using microsatellite and mitochondrial DNA markers in 688 individuals sampled in 2015 and 2017.

Characterization of 16 microsatellite marker loci in the Maasai giraffe (Giraffa camelopardalis tippelskirchi)

Sixteen polymorphic microsatellite markers with an average allele size of k = 4.3 are identified from a genomic plasmid library constructed for giraffe (Giraffa camelopardalis ssp.). Primer sequences and marker data are reported in tabular form. The markers were screened in a population of 25 Maasai giraffe (G. c. tippelskirchi) collected near the Athi River, Kenya. The average observed heterozygosity for each marker was 0.36 with an average expected heterozygosity of 0.535. Hardy-Weinberg deviations are reported from this population, which

Characterization of eight polymorphic loci for Maasai giraffe (Giraffa camelopardalis tippelskirchi) using non-invasive genetic samples

We used Illumina sequencing to develop eight novel microsatellite loci for Maasai giraffe (Giraffa camelopardalis tippelskirchi), and screened them using fecal DNA. Genetic diversity was assessed for 40 individuals from the Katavi National Park/Rukwa Game Reserve ecosystem in Tanzania. The number of alleles per locus ranged from 2 to 14 (mean = 6.2) and mean expected heterozygosity was moderate (range 0.025–0.838, mean = 0.527). These markers were successfully tested using degraded DNA and may be useful for future studies of
