These associations between animal hosts and photosynthetic algae often involve the exchange of essential macronutrients, supporting adaptation to a wide range of aquatic environments. A small yet taxonomically widespread subset of animals host photosymbionts from the core chlorophytes, a phylogenetically expansive clade of green algae. These rare instances of 'plant-like' animals have arisen independently across distantly related lineages, resulting in striking ecological and physiological diversity. Although such associations provide valuable insights into the evolution of symbiosis and adaptation to novel ecological niches, animal-chlorophyte photosymbioses remain relatively understudied. Here, we present an overview of photosymbioses between animals and chlorophytes, highlighting their independent evolutionary origins, ecological diversity and emerging genomic resources. Focusing on Porifera, Cnidaria and Xenacoelomorpha, we review shared and lineage-specific adaptations underlying these associations. We also contrast them with dinoflagellate-based systems to demonstrate their distinct ecological and cellular features. Our work sets the stage for elucidating the molecular mechanisms underlying these associations, enhancing our understanding of how interspecies interactions drive adaptation to unique ecological niches through animal-chlorophyte symbiosis.","PeriodicalId":9005,"journal":{"name":"Biology Letters","volume":"21 7","pages":"20250250"},"PeriodicalIF":3.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12308330/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144741101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, inaccurate conclusions about energy expenditure may arise if the limitations of the proxy variables being used to infer locomotion costs are not considered. The study of 'cluster' flocking behaviour in pigeons, using wingbeat frequency as a proxy for mechanical energy output, provides a useful illustration of these pitfalls. In contrast to claims in the literature, we suggest that published body kinematic values measured with accelerometers, along with our own heart rate data, show little evidence in support of the hypothesis that there is an increase in the mechanical energy costs for most pigeons to fly in a typical 'cluster' flock. Indeed, our re-analyses of acceleration-based measures of body power suggest there may be a positive energetic advantage to flying at low flock densities. We suggest that, when assessing energy expenditure using accelerometry-derived variables, the energy proxy units should be consistent with those of power, whether mass specific or absolute, and should control for differences in body mass and speed where appropriate. Accumulated total journey costs should also be assessed alongside instantaneous costs, with the former likely to be at least as ecologically significant.","PeriodicalId":9005,"journal":{"name":"Biology Letters","volume":"21 7","pages":"20250031"},"PeriodicalIF":3.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12308326/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144590382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While some organisms search for food by moving almost continuously throughout their environment, other organisms forage in one place for long periods of time. Although such a dichotomy has been previously documented in Drosophila melanogaster, the question remains which foraging strategy is better suited to maximize energy intake in a particular environment. We designed an experiment to evaluate whether the configuration of food in the environment alters the foraging behaviour of two larval strains. Assuming that one of the strains acquires more food than the other in a given environment, we examined whether variation in growth occurred between them. Our results indicate that foraging behaviour is a plastic trait, shaped by the configuration of food in the environment. Regardless of the foraging strategy, we found that larvae generally increased their locomotion when food was patchy rather than clumped. Even though we observed that some individuals actively sought food while others stayed foraging at nearby sites, we found no differences in growth rate between them. However, we suggest that foraging actively may be advantageous in polymorphic populations because such behaviour facilitates local adaptation via founder effect and gene flow.","PeriodicalId":9005,"journal":{"name":"Biology Letters","volume":"21 7","pages":"20250153"},"PeriodicalIF":2.8,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12212981/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144538151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, studies have examined these aspects of biology independently in relation to fitness. We investigated how phenotypic characteristics collectively affect overwinter survival in a wild population of yellow-necked mice. We measured behavioural activity, basal metabolic rate and body mass in late autumn, released marked mice and recaptured survivors in spring to reassess their phenotypes. Mice grew, increased metabolic rate and decreased distance moved over the winter, but when those changes were accounted for, the phenotypes were intra-individually consistent. The simultaneous selective advantages of elevated metabolism and behavioural activity during autumn suggest that the interplay between physiology and behaviour is subject to selection. Despite the lack of significant phenotypic covariation between metabolic rate and behaviour, their additive survival benefits suggest that elevated activity facilitates the development of costly metabolism in free-ranging animals. As metabolism and body mass share 84% of the common variance, we hypothesized that selectively advantageous high metabolism supports overwinter growth. The results support postulates that the behaviour-physiological phenotype is the first line of selective responses and that plasticity is an important source of variation in individuals' performance.","PeriodicalId":9005,"journal":{"name":"Biology Letters","volume":"21 7","pages":"20250195"},"PeriodicalIF":3.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12303114/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144641734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Birds are arguably among the best studied organismal groups, but even in avian clades there are some genera that have not been thoroughly surveyed. This is particularly true for taxa that occur in hyperdiverse biogeographic regions. In this study, we focus on an endemic group of New Guinean birds, the jewel-babblers (genus: Ptilorrhoa), and study the diversification history of all known taxa. We assemble a de novo genome using linked-read sequencing and genomic data for 40 historical specimens. Both phylogenomic and population-genomic analyses strongly support the recovery of a cryptic species and shed new light on the diversification history of this group. The blue jewel-babbler (Ptilorrhoa caerulescens) is a paraphyletic species complex and P. c. nigricrissus is more closely related to the phenotypically distinct and sexually dimorphic P. geislerorum, than to other P. caerulescens subspecies. These findings demonstrate that even in well-studied groups such as birds, cryptic diversity can still be a prevalent reality. Moreover, by deciphering cryptic diversity, we shed new light on the processes driving speciation within Ptilorrhoa and the need to potentially revise the taxonomic status of all subspecies.","PeriodicalId":9005,"journal":{"name":"Biology Letters","volume":"21 7","pages":"20240611"},"PeriodicalIF":3.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12303119/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144641735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Calculating speeds from trackways has become a standard approach, particularly for dinosaurs. However, the original equation was derived from predominantly mammalian data. There have been few validation studies using modern birds, the descendants of theropod dinosaurs. We used high-speed video recordings of two helmeted guineafowl (Numida meleagris) traversing mud of varying consistency. Associated trackways were digitized using photogrammetry, and stride and track lengths were measured to calculate speed. The speed calculated from trackways was higher than the measured speed for multiple speed formulae. Within-trackway stride lengths were variable, even when speed was relatively constant, but there were cases where two identical stride lengths were produced by birds moving at very different speeds. Prior work of guineafowl locomoting on a treadmill found good correspondence between measured speed and speed calculated from stride length. We attribute the discrepancy seen in our data between measured and calculated speed as resulting from non-steady state locomotion on compliant substrates. Given that tracks require compliant substrates to form, and are made by free-moving individuals, our data indicate that speed estimates from trackways are inaccurate, if not outright misleading.","PeriodicalId":9005,"journal":{"name":"Biology Letters","volume":"21 6","pages":"20250191"},"PeriodicalIF":2.8,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12187409/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144483108","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bats are generally repelled by light, but some fast-flying and agile species opportunistically forage on insects attracted to light sources. As insect activity is dependent on ambient temperature, prey abundance around light sources likely varies between cold and warm nights. Little is known on how the interacting effects of ambient temperature and anthropogenic light influence bat activity. We recorded activity of bats foraging around experimental light posts emitting different light spectra (white, green and red light) during 6 years for 2726 full nights to test how ambient temperature affects foraging activity of the abundant common pipistrelle (Pipistrellus pipistrellus). We found a strong interaction between light treatment and ambient temperature on the amount and timing of foraging activity. In warm nights, the total foraging activity increased near light posts, and the centre of foraging activity shifted towards the middle of the night. The interactive effect of ambient temperature on common pipistrelle bats foraging around anthropogenic light may contribute to shifts in food web interactions in warmer environments. This suggests that the ecological impact of anthropogenic light on bat biodiversity could be greater in warmer urban areas and warming climates.","PeriodicalId":9005,"journal":{"name":"Biology Letters","volume":"21 6","pages":"20250049"},"PeriodicalIF":2.8,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12133343/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144214826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
