Data from: Social network analysis of psychological morbidity in an urban slum of Bangladesh: a cross-sectional study based on a community census
Background Social ties are believed to play important roles in mitigating depression and anxiety, as well as fostering mental health in the population. We test this association for young urban men in Bangladesh. Methods Using a locally adapted GHQ-12 instrument, we enumerate self-reported mental health outcomes for 824 post-adolescent young men between the ages of 18 and 29 in a low-income urban community in Dhaka, Bangladesh. We further measure the social network for all our subjects and estimate the association of social network of the respondents with self-reported mental health outcomes controlling for possible confounders. Results We find there are considerable variations in both the mental health outcomes and social network across respondents. The GHQ scores (mean = 9.2, SD = 4.9) suggest significant psychological morbidity among the respondents. However, our findings imply better social ties and connections can potentially mitigate negative mental health outcomes (0.05-0.65 lower standardized GHQ score). Among other factors, being married and a recent migrant are also associated with better mental health status (0.17-0.20 and 0.16-0.17 lower standardized GHQ scores respectively). Conclusion Our results underscore the importance of social connection in providing buffer against stress and anxiety through psychosocial support from one's peer in a resource constraint urban setting. Our findings also suggest incorporating social network and ties in designing mental health policies and interventions.
Data from: Reliable effective number of breeders/adult census size ratios in seasonal-breeding species: opportunity for integrative demographic inferences based on capture-mark-recapture data and multilocus genotypes
The ratio of the effective number of breeders (Nb) to the adult census size (Na), Nb/ Na, approximates the departure from the standard capacity of a population to maintain genetic diversity in one reproductive season. This information is relevant for assessing population status, understanding evolutionary processes operating at local scales and unraveling how life-history traits affect these processes. However, our knowledge on Nb/Na ratios in nature is limited because estimation of both parameters is challenging. The sibship frequency (SF) method is adequate for reliable Nb estimation because it is based on sibship and parentage reconstruction from genetic marker data, thereby providing demographic inferences that can be compared with field-based information. In addition, capture-mark-recapture (CMR) robust design methods are well suited for Na estimation in seasonal-breeding species. We used tadpole genotypes of three pond-breeding amphibian species (Epidalea calamita, Hyla molleri and Pelophylax perezi, n = 73-96 single-cohort tadpoles / species genotyped at 15-17 microsatellite loci) and candidate parental genotypes (n = 94-300 adults / species) to estimate Nb by the SF method. To assess the reliability of Nb estimates, we compared sibship and parentage inferences with field-based information and checked for the convergence of results in replicated subsampled analyses. Finally, we used CMR data from a 6-year monitoring program to estimate annual Na in the three species and calculate the Nb/Na ratio. Reliable ratios were obtained for E. calamita (Nb/Na = 0.18-0.28) and P. perezi (0.5), but in H. molleri Na could not be estimated and genetic information proved insufficient for reliable Nb estimation. Integrative demographic studies taking full advantage of SF and CMR methods can provide accurate estimates of the Nb/Na ratio in seasonal-breeding species. Importantly, the SF method provides results that can be readily evaluated for reliability. This represents a good opportunity for obtaining robust demographic inferences with wide applications for evolutionary and conservation research.
Data from: Spatiotemporal relationship between adult census size and genetic population size across a wide population size gradient
Adult census population size (N) and effective number of breeders (Nb) are highly relevant for designing effective conservation strategies. Both parameters are often challenging to quantify, however, making it of interest to determine whether one parameter can be generalized from the other. Yet, the spatiotemporal relationship between N and Nb has not been well characterized empirically in many taxa. We analysed this relationship for 5–7 consecutive years in twelve brook trout populations varying greatly in N (49-10032) and Nb (3-567) and identified major environmental variables affecting the two parameters. N or habitat size alone explained 47–57% of the variance in Nb, and Nb was strongly correlated with effective population size. The ratio Nb/N ranged from 0.01 to 0.45 and increased at small N or following an annual decrease in N, suggesting density-dependent constraints on Nb. We found no evidence for a consistent, directional difference between variability in Nb and/or Nb/N among small and large populations; however, small populations had more varying temporal variability in Nb/N ratios than large populations. Finally, Nb and Nb/N were 2.5- and 2.3-fold more variable among populations than temporally within populations. Our results demonstrate a clear linkage between demographic and evolutionary parameters, suggesting that Nb could be used to approximate N (or vice versa) in natural populations. Nevertheless, using one variable to infer the other to monitor trends within populations is less recommended, perhaps even less so in small populations given their less predictable Nb vs. N dynamics.
Data from: Use of classical bird census transects as spatial replicates for hierarchical modeling of an avian community
New monitoring programs are often designed with some form of temporal replication to deal with imperfect detection by means of occupancy models. However, classical bird census data from earlier times often lack temporal replication, precluding detection-corrected inferences about occupancy. Historical data have a key role in many ecological studies intended to document range shifts, and so need to be made comparable with present‐day data by accounting for detection probability. We analyze a classical bird census conducted in the region of Murcia (SE Spain) in 1991 and 1992 and propose a solution to estimating detection probability for such historical data when used in a community occupancy model: the spatial replication of subplots nested within larger plots allows estimation of detection probability. In our study, the basic sample units were 1‐km transects, which were considered spatial replicates in two aggregation schemes. We fit two Bayesian multispecies occupancy models, one for each aggregation scheme, and evaluated the linear and quadratic effect of forest cover and temperature, and a linear effect of precipitation on species occupancy probabilities. Using spatial rather than temporal replicates allowed us to obtain individual species occupancy probabilities and species richness accounting for imperfect detection. Species‐specific occupancy and community size decreased with increasing annual mean temperature. Both aggregation schemes yielded estimates of occupancy and detectability that were highly correlated for each species, so in the design of future surveys ecological reasons and cost‐effective sampling designs should be considered to select the most suitable aggregation scheme. In conclusion, the use of spatial replication may often allow historical survey data to be applied formally hierarchical occupancy models and be compared with modern‐day data of the species community to analyze global change process.

Comparison of adult census size and effective population size support the need for continued protection of two Solomon Island endemics
<p>Because a population's ability to respond to rapid change is dictated by standing genetic variation, we can better predict a population's long-term viability by estimating and then comparing adult census size (<em>N</em>) and effective population size (<em>N<sub>e</sub></em>). However, most studies only measure <em>N</em> or <em>N<sub>e</sub></em>, which can be misleading. Using a combination of field and genomic sequence data, we here estimate and compare <em>N</em> and <em>N<sub>e</sub></em> in two range-restricted endemics of the Solomon Islands. Two <em>Zosterops</em> White-eye species inhabit the small island of Kolombangara, with a high elevation species endemic to the island (<em>Z. murphyi</em>) and a low elevation species endemic to the Solomon Islands (<em>Z. kulambangrae</em>). Field observations reveal large values of <em>N </em>for both species with <em>Z. kulambangrae</em> numbering at 114,781 ± 32,233 adults, and <em>Z. murphyi</em> numbering at 64,412 ± 15,324 adults. In contrast, genomic analyses reveal that <em>N<sub>e</sub></em> was much lower than <em>N</em>, with <em>Z. kulambangrae</em> estimated at 694.5 and <em>Z. murphyi</em> at 796.1 individuals. Further, positive Tajima's D values for both species suggest that they have experienced a demographic contraction, providing a mechanism for low values of <em>N<sub>e</sub></em>. Comparison of <em>N </em>and <em>N<sub>e</sub></em> suggests that <em>Z. kulambangrae</em> and <em>Z. murphyi</em> are not at immediate threat of extinction but may be at genetic risk. Our results provide important baseline data for long-term monitoring of these island endemics, and argue for measuring both population size estimates to better gauge long-term population viability.</p>

Large tree mortality census KNP (2006-2018)
<p><span>Fire and elephant herbivory are major drivers of large tree mortality in savanna ecosystems. While the spatial variation of these agents is well-studied, less attention has been paid to how disturbance history influences mortality risk for trees over time. In a long-term cohort study, we examined how the sequence of fire- and elephant-induced damage influences mortality of trees, and determined whether risk of mortality is compounded with time. Data on over 2500 large trees were collected from 22 transects in Kruger National Park, South Africa, in 2006, and trees were re-sampled in 2008, 2011, 2015, and 2018. Over the twelve year period, we recorded a cumulative death toll of 47.6% with an estimated annual mortality rate of 3-5% between 2006 and 2015, and a sharp increase to 8.8% in 2018. The main attributed agent of tree mortality was elephant damage, occurring either once or across multiple census periods. A classification tree (CT) analysis partitioned over different census periods showed that the probability of mortality for the ten most common species depended not only on the type and intensity of fire and elephant-induced damage, but also on the historical sequence of damage by these agents. In fact, elephant damage to the main stem incurred even up to 12 years earlier increases risk of mortality for large trees, especially in combination with fire damage. As expected, vulnerability to damage and risk of mortality varied between species, resulting in the potential for long-term changes in species composition at the landscape scale. Overall, this study highlights how multiple interacting agents cause emergent and lagging patterns of mortality risk for large trees in savanna ecosystems; a result that only becomes apparent through fine-scale long-term tracking of cohorts.</span></p>
