Data from: Long-term persistence of wildlife populations in a pastoral area
<p>Facilitating coexistence between people and wildlife is a major conservation challenge in East Africa. Some conservation models aim to balance the needs of people and wildlife, but the effectiveness of these models is rarely assessed. Using a case-study approach, we assessed the ecological performance of a pastoral area in northern Tanzania (Manyara Ranch) and established a long-term wildlife population monitoring programme (carried out intermittently from 2003-2008 and regularly from 2011-2019) embedded in a distance sampling framework. By comparing density estimates of the road-transect based long-term monitoring to estimates derived from systematically distributed transects, we found that the bias associated with non-random placement of transects was non-significant. Overall, cattle, and sheep and goat reached the greatest densities and several wildlife species occurred at densities similar (zebra, wildebeest, waterbuck, Kirk's dik-dik) or possibly even greater (giraffe, eland, lesser kudu, Grant's gazelle, Thomson's gazelle) than in adjacent national parks in the same ecosystem. Generalized linear mixed models suggested that most wildlife species (8 out of 14) reached greatest densities during the dry season, that wildlife population densities either remained constant or increased over the 17-year period, that herbivorous livestock species remained constant, while domestic dog population decreased over time. Cross-species correlations did not provide evidence for interference competition between grazing or mixed livestock species and wildlife species but indicate possible negative relationships between domestic dog and warthog populations. Overall, wildlife and livestock populations in Manyara Ranch appear to coexist over the 17-year span. Most likely, this is facilitated by existing connectivity to adjacent protected areas, effective anti-poaching efforts, spatio-temporal grazing restrictions, favourable environmental conditions of the ranch and spatial heterogeneity of surface water and habitats. This long-term case study illustrates the potential of rangelands to simultaneously support wildlife conservation and human livelihood goals if livestock grazing is restricted in space, time and numbers.</p>

Data from: Structural variation and its potential impact on genome instability: novel discoveries in the EGFR landscape by long-read sequencing
<p>Studies of structural variation (SV) have been challenging due to technological contraints. With the advent of third generation (long-read) sequencing technology, exploration of longer stretches of DNA not easily examined previously has been made possible. In the present study, we utilized third generation (long-read) sequencing techniques to examime SV in the <em>EGFR </em>landscape of four haplotypes derived from two human samples. We analyzed the <em>EGFR</em> gene and its landscape (+/- 500,000 base pairs) using this sequencing approach and were able to identify regions of non-coding DNA which had relatively high similarity to the most common activating <em>EGFR</em> mutation in non-small cell lung cancer. We discovered that reverse complements to the exon 19 deletion mutation which had at least 60% homology to the <em>EGFR</em> exon 19 canonical deletion and were within ± 421,000 bp of the deletion varied across the five haploid genomes examined (4 patient landscapes and hg38). Although the sample size is limited in this study, the estimated variation observed in genomic stability between the five <em>EGFR</em> haplotypes examined is novel and encourages further work to examine structural variation in larger cohorts.</p>
Data from: Long-lived marine species may be resilient to environmental variability through a temporal portfolio effect
<p>Maintenance of a portfolio of adaptive alleles may provide resilience of populations to natural environmental variability. We used Pacific ocean perch (POP; Sebastes alutus) to test for the maintenance of adaptive variation across overlapping generations. POP are a long-lived species characterized by widespread larval dispersal in their first year and a longevity of over 100 years. In order to understand how early marine dispersal affects POP survival and population structure, we used Restriction Site Associated DNA sequencing (RADseq) to obtain 11,146 single-nucleotide polymorphisms (SNPs) from 401 young-of-the-year (YOY) POP collected during surveys conducted in 2014 (19 stations) and 2015 (4 stations) in the eastern Gulf of Alaska. Population clustering analysis showed that the POP samples represented four distinct ancestral populations mixed throughout the sampling area. Based on prior work on larval dispersal of POP, these larvae are most likely from distinct parturition locations that are mixing during their pelagic dispersal life stage. Latent factor mixed models revealed that POP larvae face significant selection during their first year at sea, which were specific to the year of their birth. Thus each adult cohort's genetic composition is heavily influenced by the environmental conditions experienced during their first year at sea. Long-lived species relying on broadcast spawning strategies may therefore be uniquely resilient to environmental variability by maintaining a portfolio of cohort-specific adaptive genotypes, and age truncation due to overfishing of older cohorts may have detrimental effect on the population viability.</p>

Figure 10. The yearly decline in oviposition rate at Cross Creek from 1994 to 2017, recorded as average eggs/stem (500 plant minimum each year) for the four weeks from 22 March to 18 April. (F = 11.501, p = 0.003, R2 = 0.390). Excluding the extraordinary high value in 1995, the decline by 1,18 linear regression is about 78%. Based on a total of 3545 eggs.
