Here, we assess evolutionary covariance between limb proportions and ecological diversity of different bird lineages with altricial (high parental care) or precocial (lower parental care) developmental strategies. In addition, we model overall rates of evolutionary divergence between wing and leg skeletal proportions, allowing us to investigate the influence of developmental strategy upon adaptive traits. We show that while wing and leg proportions evolve independently of one another in altricial lineages, conforming to a modular pattern of evolution attested in birds more generally, there are strong correlations between wing and leg trait evolution in precocial lineages. Unlike precocial groups, divergent wing and leg evolution in altricial lineages is associated with access to novel flight-style combinations and is strongly associated with body mass. This suggests an adaptive association with mechanisms of growth and development. Inspection of internal wing proportions within major clades demonstrates that lineages with more altricial developmental strategies explore a wider range of mechanically relevant wing proportions, such as Brachial Index.","PeriodicalId":520757,"journal":{"name":"Proceedings.

However, recent studies also reported sensory enhancement of self-produced sounds. Here, we tested whether sensory attenuation and enhancement are signatures of an adaptation to the mean sound statistics. In 330 human participants, we tested the idea that predictions about upcoming sounds shift auditory processing to the average sound context. Participants produced sounds between 40 and 80 decibels (dB) and rated their loudness. Estimates of perceived loudness followed a regression to the mean sound level. The effect was similar for self-produced and passively observed but temporally predictable tones, suggesting predictability alone drives perceptual changes. We then artificially created a new mean sound level by presenting sessions in which subjects mostly (80% of trials) produced either loud (80 dB) or quiet (40 dB) tones. In loud contexts, rarely presented quiet tones were enhanced, and in quiet contexts, loud tones were attenuated. Our results challenge the dominant forward model explanation, which attributes sensory attenuation to predictive suppression of self-generated stimuli, and instead open the door for alternative explanations. Our findings point to regression towards the mean sound level as the most plausible account for predictable sounds.","PeriodicalId":520757,"journal":{"name":"Proceedings.

Increased copepod Δ13C, reflecting increased metabolic demands, was found at elevated temperatures and when fed with poor-quality food. Multiple regression models highlighted the importance of specific ω-3 and ω-6 fatty acids for body and clutch size, supporting our conclusion that metabolic and food quality-mediated responses to temperature rise resulted in energetic imbalances that mediated the interaction between food quality and the temperature-size rule with negative consequences for reproductive output.","PeriodicalId":520757,"journal":{"name":"Proceedings.

Understanding the factors influencing anthelmintic resistance is crucial to mitigate the threat posed by these parasites. Due to difficulties in studying parasitic worms in the laboratory, the non-parasitic nematode Caenorhabditis elegans is used as a model organism to investigate anthelmintic resistance evolution. However, the suitability of this free-living nematode as a model for parasitic worms is debatable due to its rare androdioecious reproductive system, raising questions about the generalizability of findings from evolutionary experiments in C. elegans to other species. In this study, we developed a polygenic, population genetic model combined with pharmacodynamic approaches to investigate the effects of reproductive strategy and other aspects, such as dominance, mutational effects, the number of loci and population size, on determining the dynamics and outcome of evolutionary processes. We found that androdioecious populations showed both rapid initial adaptation typical for hermaphrodites and tolerance to high drug concentrations observed in dioecious populations. They also exhibited the highest diversity and shortest time for the fixation of the beneficial allele. These results suggest that androdioecious populations can harness the advantages of both selfing and outcrossing, optimizing their reproductive strategy in response to drug selection.","PeriodicalId":520757,"journal":{"name":"Proceedings.

We integrate historical and contemporary data from museum collections and online records for 45 butterfly species from Sulawesi (Indonesia) to explore species richness trends over the past 166 years (1857-2022), test whether recent trends mirror longer-term trends and examine whether species that are endemic, forest-dependent and/or host-plant specialists have declined the most. Over the 166-year time period, we found no systematic decline in overall species richness, despite shorter-term multi-decadal changes (positive, stable and negative trends). Recent trends generally did not match longer-term trends. Contrary to expectation, we found long-term increases in some species, particularly those that are non-endemic or open-habitat tolerant, whereas endemic and/or forest-dependent species showed more mixed trends, either stable or declining. We find long-term stability in regional species richness, but this masks composition changes that include more non-endemic and open-habitat species over time.

While we hold a broad understanding of how drought impacts plant populations, predicting drought's demographic effects on animal populations remains a challenge, particularly for invertebrates. Here, we use 7 years of bumble bee nest surveys spanning a period with two historic droughts to estimate impacts of drought on bumble bee nest abundance and apparent survival. Nest abundance significantly declined with drought (overall average of 19.3 versus 11.3 nests in non-drought versus drought years). Relative nest abundances of Bombus impatiens and Bombus griseocollis, two common species in this system, did not change with drought despite differences in life history and apparent survival. B. impatiens abundance in forests increased during droughts (approx. 60% of nests in forests versus 20-40% in drought versus non-drought years). Nests of rarer species were absent from our survey area after the first of the two droughts, but the two common species recovered quickly in the year after each drought. This study demonstrates that well-known effects of drought on floral resources likely translate to population-level impacts in bumble bees. It also highlights the importance of long-term monitoring for detecting impacts of intermittent environmental disturbances.","PeriodicalId":520757,"journal":{"name":"Proceedings.

The latter occurs when behaviours mitigate selection pressures that otherwise would target associated traits. Therefore, environments that facilitate adaptive behavioural plasticity could relax the strength of natural selection, but experimental evidence for this prediction remains scarce. Here, we first demonstrate that maternal care behaviour in the beetle Callosobruchus maculatus is dependent on environmental cues that allow females to reduce larval competition via learning and informed oviposition choices. We show that this facilitation of maternal care relaxes selection against deleterious alleles in offspring. We further find that mothers of low genetic quality generally provide poorer care. However, when receiving environmental cues providing accurate information about future host-quality, the increased opportunity for adaptive behavioural plasticity reduced genetic differences in maternal care, further relaxing selection against deleterious alleles. We use our data to illustrate how the identified link between adaptive behavioural plasticity in maternal care and the strength of natural selection can impact indirect genetic effects between mothers and offspring and the accumulation of cryptic genetic loads in populations inhabiting predictable environments.","PeriodicalId":520757,"journal":{"name":"Proceedings.

The most direct information on species losses comes from recent extinctions. However, our understanding of these recent, human-related extinctions is incomplete across life, especially their causes and their rates and patterns among clades, across habitats and over time. Furthermore, prominent studies have extrapolated from these extinctions to suggest a current mass extinction event. Such extrapolations assume that recent extinctions predict current extinction risk and are homogeneous among groups, over time and among environments. Here, we analyse rates and patterns of recent extinctions (last 500 years). Surprisingly, past extinctions did not strongly predict current risk among groups. Extinctions varied strongly among groups, and were most frequent among molluscs and some tetrapods, and relatively rare in plants and arthropods. Extinction rates have increased over the last five centuries, but generally declined in the last 100 years. Recent extinctions were predominantly on islands, whereas the majority of non-island extinctions were in freshwater. Island extinctions were most frequently related to invasive species, but habitat loss was the most important cause (and current threat) in continental regions. Overall, we identify the major patterns in recent extinctions but caution against extrapolating them into the future.","PeriodicalId":520757,"journal":{"name":"Proceedings.

Annual actograms unexpectedly revealed that the nocturnal migratory flights of the shrikes were organized in a highly structured way, with flights aggregated into segments that could be readily identified for all individuals, showing low variability and thus high consistency between individuals. These results suggest that the execution of migratory flights is under a high degree of control according to a rather detailed internal travelling plan for the annual migration cycle. Potentially, the control of migratory flight under natural conditions depends on a complex feedback process where external cues associated with the geographic, temporal and nutritional situation of the bird are required for the internal programme to properly regulate the successive segmental flight steps of the migratory journey.
