Supplemental datasets for 'A near telomere-to-telomere phased reference assembly for the male mountain gorilla (Gorilla beringei beringei)'
<p>The endangered mountain gorilla <em>Gorilla beringei beringei</em> faces numerous threats to its survival, highlighting the urgent need for genomic resources to aid conservation efforts. Here, we present a near telomere-to-telomere, haplotype-phased reference genome assembly for a male mountain gorilla generated using Pacbio HiFi and Oxford Nanopore Ultralong data. The resulting assembly exhibits exceptional contiguity, with contig N50 of ~ 95 Mbps for the combined pseudohaplotype (3,540,458,497 bps, and 56.5 Mbps (3.1 Gbps) and 51.0 Mbps (3.2 Gbps) for the maternal and paternal haplotypes and an average QV of 65.15 (error rate = 3.1 x 10-7). These represent substantial improvements over most other available primate genomes. This high-quality reference genome provides an invaluable resource for future studies on gorilla evolution, adaptation, and conservation, ultimately contributing to the long-term survival of this iconic species.</p> <p>A preprint for this work is available at bioRXiv, doi: https://doi.org/10.1101/2024.10.28.620258</p>
Data from: Social and ecological factors alter stress physiology of Virunga mountain gorillas (Gorilla beringei beringei)
Living in a rapidly changing environment can alter stress physiology at the population level, with negative impacts on health, reproductive rates, and mortality that may ultimately result in species decline. Small, isolated animal populations where genetic diversity is low are at particular risks, such as endangered Virunga mountain gorillas (Gorilla beringei beringei). Along with climate change‐associated environmental shifts that are affecting the entire population, subpopulations of the Virunga gorillas have recently experienced extreme changes in their social environment. As the growing population moves closer to the forest's carrying capacity, the gorillas are coping with rising population density, increased frequencies of interactions between social units, and changing habitat use (e.g., more overlapping home ranges and routine ranging at higher elevations). Using noninvasive monitoring of fecal glucocorticoid metabolites (FGM) on 115 habituated Virunga gorillas, we investigated how social and ecological variation are related to baseline FGM levels, to better understand the adaptive capacity of mountain gorillas and monitor potential physiological indicators of population decline risks. Generalized linear mixed models revealed elevated mean monthly baseline FGM levels in months with higher rainfall and higher mean maximum and minimum temperature, suggesting that Virunga gorillas might be sensitive to predicted warming and rainfall trends involving longer, warmer dry seasons and more concentrated and extreme rainfall occurrences. Exclusive use of smaller home range areas was linked to elevated baseline FGM levels, which may reflect reduced feeding efficiency and increased travel efforts to actively avoid neighboring groups. The potential for additive effects of stress‐inducing factors could have short‐ and long‐term impacts on the reproduction, health, and ultimately survival of the Virunga gorilla population. The ongoing effects of environmental changes and population dynamics must be closely monitored and used to develop effective long‐term conservation strategies that can help address these risk factors.

Data from: Going to extremes for sodium acquisition: use of community land and high-altitude areas by mountain gorillas Gorilla beringei in Rwanda
Space use in mammals may be influenced not only by their primary foods, but also by localized sources of physiologically critical resources such as sodium-rich plants. We examined how sodium acquisition influences habitat use in mountain gorillas (Gorilla beringei) in Rwanda which have increased the amount of time they forage on community land outside of Volcanoes National Park (VNP), where eucalyptus (Eucalyptus spp.) tree bark is their most frequently eaten food. We measured sodium content in samples from 34 main dietary items and quantified sodium intake by 22 gorillas in three social groups over one-year. On a dry weight basis, eucalyptus bark contains 3100 mg Na/kg. In contrast, the four herbs most frequently exploited for food inside the park are relatively sodium-poor (<70mg/kg each). Further, sodium intake rates were highest when the gorillas were on community land. Of the two groups that fed outside of the park, one obtained 73% and the other one 45% of their sodium in that habitat despite only feeding for minimal amounts of time there. However, one group that did not feed on community land acquired 78% of its sodium in the subalpine and alpine zones through the consumption of pith of giant lobelias and groundsels. Obtaining sodium thus likely creates an incentive for the gorillas to leave the park and make forays into high-altitude habitat. Both strategies are not without risks: exiting their natural habitat and feeding on crops may increase human-wildlife conflict and visiting high-altitude areas may increase the risk of hypothermia.
