They represent patterns in which fitness is obtained from resource investments in reproductive functions. The monotonic forms that have been used for gain curves can represent fitness accrual by individuals, but only on the assumption that sufficient mates are always available to allow the stipulated monotonic pattern of reproductive success to occur. However, sexual populations do not have external banks of mating opportunities that lie outside the dynamics of the population (such opportunities would, by definition, be part of the population). Thus, the reproductive behaviour of whole populations cannot be simple scaled-up versions of individual gain curves. As sex allocation evolves within a breeding population, frequency-dependent selection creates a shifting advantage for the rarer sex. Individual gain curves cannot then remain stable possibilities at the population level. Evolutionary models based on fixed gain curves can predict evolutionary outcomes with unequal total fitness for male and for female function, an outcome that the biology of syngamy does not allow. Such biologically impossible outcomes are easily demonstrated. Gain curves have also been widely used as a framework for interpretation of interspecific empirical patterns, such as low male allocation in monogamously mating hermaphroditic animals or self-pollinating plants, and higher male allocation in wind-pollinated than in animal-pollinated plants. However, if gain curves incorrectly characterize whole populations or species, interspecific differences in gain curves cannot explain these patterns. Even if they superficially appear to predict the empirical pattern, other processes must be operating. The selective effects of local mating competition and sex-specific dispersal patterns have long been known. They are likely replacements for gain curves as explanations of many broad interspecific patterns, but the predominance of gain-curve explanations has distracted attention from these alternatives. A revision of our understanding of gain curves seems needed.</p>","PeriodicalId":133,"journal":{"name":"Biological Reviews","volume":" ","pages":"1554-1567"},"PeriodicalIF":11.7,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146083646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this assumption is conceptually flawed. Many core maintenance processes underlying SMR are temporally partitioned across sleep and wakefulness and are not continuously active. We argue that instead of representing a singular metabolic state, SMR is better defined as a shifting metabolic mosaic where maintenance functions are distributed unevenly across different sleep-wake states, including metabolically and functionally distinct phases such as non-rapid eye movement (NREM) and rapid eye movement (REM) sleep. SMR measured during wakefulness will mainly represent ion regulation, thermoregulation, sensory processing, and substrate cycling. Meanwhile, SMR measured during sleep primarily includes processes upregulated during sleep, including protein synthesis, cellular repair, immunity, and synaptic plasticity. Our models demonstrate that SMR values measured exclusively during wake or sleep consistently over- or underestimate daily maintenance costs depending on the time spent in specific sleep states and when SMR was measured. In addition, treatment or environmental effects on the costs of specific processes may be entirely missed if metabolic measures occur during an inappropriate sleep-wake state. The temporal partitioning of maintenance processes suggests that traditional and current approaches to SMR measurement may confound true metabolic variation with individual and species-specific differences in sleep architecture, with implications for the estimation of energy budgets, trait heritability, environmental effects on metabolic rate, and metabolic scaling relationships. We propose redefining organismal maintenance costs as a time-integrated profile of metabolic demands, but also suggest that state-specific SMR measurements are appropriate if the sleep-wake measurement period aligns with that of the behavioural, physiological, or ecological context of interest. Moving beyond the fiction of a constant maintenance baseline would provide more refined insights into the bioenergetic foundations of ecological performance and evolutionary constraints.</p>","PeriodicalId":133,"journal":{"name":"Biological Reviews","volume":" ","pages":"1491-1510"},"PeriodicalIF":11.7,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13149784/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146027914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, significant variation in experimental and analytical approaches has hindered our broader understanding of seagrass-microbe interactions and the potential existence of a functional core microbiome, i.e. microbial taxa that are consistently present on hosts and likely exert a disproportionate impact on host function. Through a systematic review, we aimed first to understand current trends and knowledge gaps in seagrass-microbe research. Additionally, we conducted a systematic mapping of global 16S ribosomal RNA (rRNA) gene sequencing data to characterise core bacterial taxa in three plant microenvironments (leaves, roots and rhizosphere) across multiple species and within a highly studied seagrass species, Zostera marina. The results revealed a growing number of studies since the 2010s manipulating environmental variables and/or seagrass microbes to investigate their roles in seagrass performance and responses to stressors. Most studies have primarily focused on seagrass leaves, examined a limited number of species, and investigated only bacteria via 16S rRNA gene amplicon sequencing. A few studies attempted to characterise seagrass core microbiomes, often using highly variable approaches to define core taxa. Our systematic mapping based on global sequencing data allowed the identification of prevalent bacterial taxa belonging to the families Desulfocapsaceae and Sulfurovaceae in the seagrass rhizosphere, which may play an important role in the performance of Z. marina and other seagrass species. The results also showed that many other bacterial families were prevalent across different seagrass microenvironments, such as Rhodobacteraceae and Flavobacteriaceae, with substantial taxonomic variability and functional metabolic redundancy.

On the one hand, they contribute substantially to biodiversity and support ecosystem stability by performing essential ecological functions. On the other, they can impose health burdens on their hosts, causing diseases in both animals and humans. Despite their significance, our understanding of how parasitic organisms are affected by human-driven environmental change remains poor. In other well-studied groups such as free-living birds, mammals and insects, long-term ecological data sets have been instrumental in elucidating temporal trends in abundance or diversity and linking them to anthropogenic drivers. For parasites however, overarching long-term trends in infection levels or diversity have yet to be identified. Here we provide an overview of the research approaches developed to study long-term changes in parasite systems and the trends highlighted by these studies. Our aims were to help researchers make informed methodological decisions when designing their research, and to provide recommendations for future long-term research on parasite ecology. To this end, we performed a systematic literature search on long-term analyses of eukaryotic parasites of wild animals and identified four types of approaches deployed to gather long-term data: (i) long-term monitoring; (ii) snapshot resampling; (iii) literature-based research; and (iv) natural history collection-based studies. Our results revealed striking differences in the temporal scope, geographical scale of sampling, sample sizes and taxonomic resolution of parasite identification among these approaches. However, no overarching trends in parasite infection levels or diversity were identified. When detected, significant temporal changes were often linked to anthropogenic disturbances, but these claims were rarely supported by inferential analyses. Overall, our results show that our understanding of long-term trends in parasite systems remains hampered by data scarcity and research biases. To address these issues, we advocate for the establishment of large-scale parasite monitoring programmes combined with existing ecological monitoring projects, as well as the development of new scalable biomonitoring tools.
