Fitness and cold tolerance of Spodoptera frugiperda fed on corn and two winter crops(Original data)
<p>Fall armyworm (FAW) <em>Spodoptera frugiperda</em> is a major migratory and polyphagous pest. Overwintering, migrating and colonizing characters of FAW are closely related to vegetation and host adaptation. In this study, oviposition preference, feeding preference, fitness and cold tolerance of FAW fed on spring & summer crop (corn) and two winter crops (cabbage, <em>Brassica campestris </em>and rape,<em> B. napus</em>). We observed that FAW could complete their life cycle by feeding cabbage and rape, although fitness was not as good as corn. FAW fed on cabbage had higher survival, pupal weight, and host suitability index than rape while larvae preferred to feed on rape leaves and females preferred to lay eggs on rape plants. In addition, FAW larvae fed on cabbage had the shortest recovery time from chill coma compared to corn and rape, indicating that cold tolerance of FAW larvae was improved by feeding on cabbage. Consequently, cabbage could be an ideal host for FAW which needed to survive and reproduction in winter. These results improve our understanding of host selection and adaption of FAW, as well as lay a foundation for the prediction of FAW overwintering.</p>

Behavioural, demographic and fitness consequences of social instability in cooperatively breeding dwarf mongoose groups
<p><span>Social instability frequently arises in group-living species, but the potential costs</span> <span>have rarely been investigated in free-living cooperative breeders, especially across different timeframes.</span><span> Using natural observations, body-mass measurements and life-history data from dwarf mongooses (<em>Helogale</em> <em>parvula</em>), we determined the short- and longer-term consequences of a change in one of the dominant breeding pair. We found that a new breeder led to alterations in both collective and individual behaviour (i.e., increases in communal scent-marking, engagement in intergroup interactions, sentinel activity and within-group grooming), as well as reduced body-mass gain, further demographic changes and decreased reproductive success (i.e., fewer pups surviving to adulthood). The effects were particularly apparent when it was the female breeder who changed; new female breeders were younger than more experienced counterparts. Our findings support the idea that stability and cooperation are strongly linked and provide potential reasons for previously documented health and fitness benefits of social stability.</span></p>

Data for: Lack of intergenerational reproductive conflict, rather than lack of inclusive fitness benefits, likely explains absence of post-reproductive lifespan in long-finned pilot whales
<p>Life history theory suggests that individuals should reproduce until death, yet females of a small number of mammals live for a significant period after ceasing reproduction, a phenomenon known as post-reproductive lifespan. It is thought that the evolution of this trait is facilitated by increasing local relatedness throughout a female's lifetime. This allows older females to gain inclusive fitness through helping their offspring (known as a mother effect) and/or grandoffspring (known as a grandmother effect), rather than gaining direct fitness through reproducing. However, older females may only benefit from stopping reproducing when their direct offspring compete with those of their daughters. Here, we investigate whether a lack of post-reproductive lifespan in long-finned pilot whales (<em>Globicephala melas</em>) results from minimal benefits incurred from the presence of older females, or from a lack of costs resulting from mother-daughter co-reproduction. Using microsatellite data, we conducted parentage analysis on individuals from 25 pods and find that younger females were more likely to have offspring if their mother was present in their pod, indicating that mothers may assist inexperienced daughters to reproduce. However, we found no evidence of reproductive conflict between co-reproducing mothers and daughters, indicating that females may be able to reproduce into old age whilst simultaneously aiding their daughters in reproduction. This highlights the importance of reproductive conflict in the evolution of a post-reproductive lifespan and demonstrates that mother and grandmother effects alone do not result in the evolution of a post-reproductive lifespan.</p>

MRExo 4D Fit: Mass-Radius-Stellar-Mass-Insolation Small Planet
<p>A sample of 182 planets from the NASA Exoplanet Archive queried on 2023 March 6 for planets with masses and radii $> 3\sigma$ precision, planetary radii $<$ 4 \earthradius~ and stellar masses $<$ 1.5 \solmass described in Section 2 of Kanodia et al. 2023.</p> <p>We then perform a 4-D fit to the dataset described above, across planetary masses, radii, insolation fluxes, and stellar masses. We use 40 degrees across all four dimensions, and perform 100 trials for Monte-Carlo and Bootstrap simulations each. This is described in Section 3.1 of Kanodia et al. 2023.</p> <p>For ease of download, we have broken up the fit into three separate .zip files -</p> <p>1. Without the bootstrap or Monte-Carlo results (AllPlanet_RpLt4_StMlt1.5_MRSStM_d40_0MC_0BS.zip)</p> <p>2.

Data for: Genotypes selected for early and late avian lay date differ in their phenotype, but not fitness, in the wild
<p><span>Global warming has shifted phenological traits in many species, but whether species are able to track further increasing temperatures depends on the fitness consequences of additional shifts in phenological traits. To test this, we conducted a genomic selection experiment on wild great tits from the Hoge Veluwe study population (The Netherlands) to obtain great tits (<em>Parus</em> <em>major</em>) with genotypes for extremely early and late egg lay dates and measured phenology and fitness of selected great tit females under wild conditions.</span></p> <p><span>Females with early genotypes advanced lay dates relative to females with late genotypes, but not relative to non-selected females. Females with early and late genotypes did not differ in the number of fledglings produced, in line with the weak effect of lay date on the number of fledglings produced by non-selected females in the years of the experiment. Our study is the first application of genomic selection in the wild and led to an asymmetric phenotypic response that indicates the presence of constraints toward early, but not late, lay dates.</span></p>
