Corpus and list of keywords from Improving sustainable crop protection using population genetics concepts
<p>Corpus extracted in April 2021 from the ISI Web of Science portal (https://www.webofscience.com) with the following request: ‘Plant AND Resistan* AND Durab*’. A first corpus of 2522 articles was built considering all publication years for this extraction. This collection was then refined by categories to remove articles outwith the scope of our search (e.g. related to durable resistant materials for constructions). We also kept only articles cited at least once. The final corpus was composed of 1783 articles from 1979 to 2021:</p> <ul> <li>CORPUS_plant_resistance_durability.zip</li> </ul> <p>List of keywords used for the network presented in the article:</p> <ul> <li>keywords_list.csv</li> </ul>

Data from: Sustained positive consequences of genetic rescue of fitness and behavioural traits in inbred populations of Drosophila melanogaster
<p><span>One solution to alleviate the detrimental genetic effects associated with reductions in population size and fragmentation is to introduce immigrants from other populations. While the effects of this genetic rescue on fitness traits are fairly well known, it is less clear to what extent inbreeding depression and subsequent genetic rescue affects behavioural traits. In this study, replicated crosses between inbred lines of <em>Drosophila melanogaster</em> were performed in order to investigate the effects of inbreeding and genetic rescue on egg-to-adult viability and negative geotaxis behaviour - a locomotor response used to measure e.g. the effects of physiological ageing. Transgenerational effects of outcrossing were investigated by examining the fitness consequences in both the F<sub>1</sub> and F<sub>4</sub> generation. The majority of inbred lines showed evidence for inbreeding depression for both egg-to-adult viability and behavioural performance (95% and 66% of lines, respectively), with inbreeding depression being more pronounced for viability compared to locomotor response. Subsequent outcrossing with immigrants led to an alleviation of the negative effects for both viability and geotaxis response resulting in inbred lines being similar to the outbred controls, with beneficial effects persisting from F<sub>1</sub> to F<sub>4</sub>. Overall, the results clearly show that genetic rescue can provide transgenerational rescue of small, inbred populations by rapidly improving population fitness components. Thus, we show that even the negative effects of inbreeding on behaviour, similar to that of neurodegeneration associated with physiological ageing, can be reversed by genetic rescue.</span></p>

Data from: Forest without prey: livestock sustain a common leopard population in Pakistan
Human–carnivore conflict is one of the major challenges in the management of populations of large carnivores. Concerns include the increasing human population; habitat loss as a result of degradation and fragmentation of forest; and livestock predation as a result of a lack of natural prey, leading to retaliatory killings of wild carnivores. Conflicts may be further aggravated by occasional attacks that result in injury and loss of human life. The level of consumption of prey species by a predator is a benchmark to evaluate the scale of this conflict. We used a newly developed DNA-based diet analysis to study the prey profile of common leopards Panthera pardus in Ayubia National Park, Pakistan. The results suggest that the common leopard is a generalist predator, subsisting mainly on domestic animals. Based on the frequency of occurrence of prey items in 57 faecal samples, the diet of the leopard is dominated by domestic goat Capra hircus (64.9%), followed by domestic dog Canis lupus familiaris (17.5%) and cow Bos taurus (12.3%). Domestic animals (goat, dog, cow, water buffalo Bubalus bubalis, horse Equus caballus and sheep Ovis aries) occurred in 54 (95%) of the 57 samples. We recommend a two-step strategy to mitigate this conflict: (1) introducing incentives for increased acceptance of leopards among local communities in the vicinity of the protected area and (2) increasing the availability of wild prey. We hope that the results of this study will contribute to the survival of the leopard in Pakistan.

Data from: Sexual selection sustains biodiversity via producing negative density‐dependent population growth
1. Mechanisms for maintaining biodiversity are still unclear despite considerable research. The classic theory predicts that stable co‐occurrence of competitive species requires niche differentiation. In fact, the co‐occurring species are often differentiated from each other. However, the neutral theory assuming equivalence of the reproductive rate of all individuals regardless of the species in a biological community has successfully recreated the observed patterns of species abundance distribution. This success is based on the unrealistic assumption suggesting that some mechanisms eliminate interspecific differences in the reproductive rates. 2. Here, I present sexual selection as a candidate of the mechanisms by constructing analytical and simulation models. Sexual selection affects the traits that increase mating success even at the expense of fecundity when the species is abundant. By contrast, when the species is at a relatively low density, this negative effect on fecundity is mitigated because less competition for mating occurs in the rare species. 3. The analytical model of this effect on fecundity predicted that sexual organisms stop population growth before exhausting resources due to the effect. This prediction was confirmed by simulation models. The simulations also showed that hundreds of competitive species with interspecific differences in reproductive potential can coexist over 10,000 generations. Moreover, species abundance distributions obtained from the simulations were similar to the patterns observed in field data. Given the generality of sexual reproduction in nature, sexual selection is likely to play a significant role in sustaining biodiversity over a broad range of environments. 4. Synthesis. Evolution does not always maximize population growth rate. This study shows that evolution of sexual selection controls the population growth rate according to density and stabilizes the population size. This stabilizing effect has a potential to rescue endangered species from extinction, prevent overgrowth of common species, promote coexistence of competitive species, and successfully recreate the observed patterns of species abundance distribution.
