Rivers are key geographic features that drive diversification of the Amazonian biota, but they are also dynamic, which challenges their role as long-term barriers to dispersal and gene flow. The impacts of such river dynamics on organismal evolution have only recently been explored in detail. Here I examine biodiversity patterns and processes in Amazonia to elucidate how taxa diversify in the context of river network dynamics. I borrow the River Capture Hypothesis from ichthyology, and draw on evidence from speciation genomics, hybrid zones, and community assembly to demonstrate the effects of river network evolution on biodiversification. The idea is simple: populations of organisms whose dispersal is restricted by rivers become semi-isolated by rivers. Drift and selection against introgression drive divergence, but as rivers move, previously isolated populations come into secondary contact, facilitating lineage fusions or the migration of hybrid zones to other rivers. The basin's unique macroecological patterns and rich biota thus may have resulted from repeated divergences, lineage fusions, and range expansions around a network of non-stationary extrinsic barriers with variable results depending on the degree of intrinsic reproductive isolation that accumulates during this process. The evolutionary consequences of dynamic landscapes extend beyond Amazonia as \"fission-fusion-fission\" cycles modulate the diversification and spatial patterning of life on Earth in general.</p>","PeriodicalId":133,"journal":{"name":"Biological Reviews","volume":" ","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144148891","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}

Within the context of mutualistic symbioses, parasites are otherwise cooperative individuals or strains that appropriate a disproportionate amount of the synergistic products. In the context of antagonistic symbioses, there is no pretence of cooperation, and instead parasites are defined as individuals or strains that derive fitness benefits at a fitness cost to their hosts. In both cases, parasitism is selected for at the lower level (that of the individual symbiont) but selected against at the higher level (the group of symbionts in a single host). Despite these similarities, these different sorts of parasitism likely evolve by different pathways. Once a host-symbiont relationship initiates, if functional synergy is lacking, the relationship will remain exploitative, although parasites may differ in their detrimental effects on the host and the higher-level unit. If functional synergy is present, however, cooperation may develop with benefits for both host and symbionts (i.e. mutualism). Nevertheless, parasites may still evolve from within these incipient relationships when individuals or strains of symbionts act parasitically by defecting from the common good to further their selfish replication. Levels-of-selection dynamics thus underlie both forms of parasitism, but only in the case of latent functional synergy can true symbiotic complexity at the higher level emerge.</p>","PeriodicalId":133,"journal":{"name":"Biological Reviews","volume":" ","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144141055","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}

The currently known forms of parasitic reproductive manipulations are male-killing, feminization, cytoplasmic incompatibility, parthenogenesis induction and distortion of sex allocation. While all of these phenomena represent adaptations that enhance parasite spread, they differ in the mechanisms involved and the consequent infection dynamics. We focus here on the latter aspect, summarizing existing theoretical literature on infection dynamics of all known reproductive manipulation types, and completing the remaining knowledge gaps where dynamics have not been modelled yet. Our unified framework includes the minimal model components required to describe the effects of each manipulation. We establish invasion criteria for all potential combinations of manipulative endosymbionts, yielding predictions for an endosymbiont's increase from rarity within a host population that is initially either uninfected or infected with a different symbiont strain. We consider diplodiploid and haplodiploid hosts, as the mechanisms as well as the infection dynamics of reproductive manipulations can differ between them. Our framework reveals that endosymbionts that a priori have the best invasion prospects are not necessarily the most commonly found ones in nature; priority effects play a role too, and cytoplasmic incompatibility excels in this regard. As a whole, considerations of the ease with which a symbiont spreads have to be complemented with knowledge of how easy it is to achieve a particular manipulation, and with factors influencing the probability that interspecific host switching occurs and succeeds.</p>","PeriodicalId":133,"journal":{"name":"Biological Reviews","volume":" ","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144118396","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}

The intricacies of interspecific disease transmission determine when a disease can spread to a novel host, including humans (zoonosis), and the severity of emerging epidemics. Interspecific disease transmission also mediates long-term disease prevalence within a multi-host community which is at the core of the disease-diversity relationship. Mathematical models play a central role in formulating predictions about spillover, prevalence, and the disease-diversity relationship. Yet, how the complexity of transmission is captured (or not) by the assumptions of these models is often unclear. Here, we decompose the transmission process into five biological stages using bovine tuberculosis (bTB) as an illustrative example of transmission in a multi-host system. We then examine the often-implicit assumptions that classic compartmental models make about this process. We use the intuition gained from this decomposition to formulate hypotheses for how transmission can mediate outbreak potential, infection prevalence, and the amplifying or diluting effects of host diversity on disease prevalence. We further illustrate the key principles and implications of transmission with a diverse array of examples of multi-host pathogens.

Recent molecular clock analyses based on only unequivocal metazoan fossil calibrations suggest that Porifera were present by at least 590 million years ago (Ma), all major eumetazoan clades originated in the mid-late Ediacaran, and bilaterians were probably present by the late Ediacaran. An alternating pelagic larval (potentially for dispersal) and benthic adult life cycle appears to be an ancestral feature of metazoans. A compilation of inferred reproductive styles from the fossil record reveals that the low-competition, deep-water communities of the Ediacaran Avalon macrofossil assemblage (ca. 575 to 560 Ma) had current-borne sexually produced larval with both local (non-planktotrophic, with no feeding) and more widespread (planktotrophic, with feeding) dispersal followed by vegetative growth. By ca. 560 Ma, White Sea assemblage communities in shallow settings show dense aggregations, which were often dominated by single populations of episodic sexually produced larval spatfalls. Some taxa may show potential larval philopatry. By 550 Ma, with the rise of biomineralization and colonisation of shallow marine carbonate settings, the ability to encrust hard substrates, create multiple branches via budding, and rudimentary mutual attachment of inferred clones, first appear. The dominant apparent mode of reproduction throughout the Ediacaran was therefore via current-borne sexually produced larvae followed by asexual reproduction, via either budding, fragmentation or fission. In these communities where biotic interactions were limited, this enabled colonisation of newly available soft and hard substrates followed by rapid growth. Early Cambrian communities showed increased endemism, enhanced trophic interactions and widespread macropredation. By the early Cambrian Fortunian stage (ca. 535 Ma), gonochorism (separate sexes) may have been present in priapulid worms. During Cambrian Stage 2 (ca. 532 Ma), internal fertilisation probably appeared in molluscs but widespread planktotrophy did not appear until the latest Cambrian/early Ordovician. Mutual attachment of diverse skeletal taxa became more common, particularly within reefs. Evidence for egg brooding and parental care in arthropods had appeared by the early Stage 3 (ca. 518 Ma). While reproductive styles were independently acquired, this overall pattern suggests a shift both to higher fecundity and to higher quality offspring in some groups during the Ediacaran-Cambrian Radiation, driven by increasing biotic interactions, including the rise of macropredation.</p>","PeriodicalId":133,"journal":{"name":"Biological Reviews","volume":" ","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144075059","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}

Non-human primates are instead assumed to display less-salient eye morphologies that help mask their gaze to facilitate competitive, rather than cooperative actions. Here, we argue that the CEH, although continuing to be influential, lacks robust empirical support. Over the past two decades, multidisciplinary research has undermined its original rationale and central premises: human eye pigmentation does not uniquely stand out among primates, it is not uniform at species level and the available evidence does not conclusively suggest that it facilitates gaze following to notable extents. Hence, the CEH currently provides a theoretical framework that risks confusing, rather than informing, inferences about the evolution of human external eye appearance and its selective drivers.

This is also the case for mountain soils, but no study to date has provided an overall synthesis of the current state of knowledge. Here we fill this gap with a first global analysis of published research on cryptogams, microorganisms, and fauna in mountain soils above the treeline, and a structured synthesis of current knowledge. Based on a corpus of almost 1400 publications and the expertise of 37 mountain soil scientists worldwide, we summarise what is known about the diversity and distribution patterns of each of these organismal groups, specifically along elevation, and provide an overview of available knowledge on the drivers explaining these patterns and their changes. In particular, we document an elevation-dependent decrease in faunal diversity above the treeline, while for cryptogams there is an initial increase above the treeline, followed by a decrease towards the nival belt. Thus, our data confirm the key role that elevation plays in shaping the biodiversity and distribution of these organisms in mountain soils. The response of prokaryote diversity to elevation, in turn, was more diverse, whereas fungal diversity appeared to be substantially influenced by plants. As far as available, we describe key characteristics, adaptations, and functions of mountain soil species, and despite a lack of ecological information about the uncultivated majority of prokaryotes, fungi, and protists, we illustrate the remarkable and unique diversity of life forms and life histories encountered in alpine mountain soils. By applying rule- as well as pattern-based literature-mining approaches and semi-quantitative analyses, we identified hotspots of mountain soil research in the European Alps and Central Asia and revealed significant gaps in taxonomic coverage, particularly among biocrusts, soil protists, and soil fauna. We further report thematic priorities for research on mountain soil biodiversity above the treeline and identify unanswered research questions. Building upon the outcomes of this synthesis, we conclude with a set of research opportunities for mountain soil biodiversity research worldwide. Soils in mountain ecosystems above the treeline fulfil critical functions and make essential contributions to life on land.

A trade-off between quality and vulnerability across antagonistic interactions.","authors":"Mairenn C Attwood","doi":"10.1111/brv.70037","DOIUrl":"https://doi.org/10.1111/brv.70037","url":null,"abstract":"<p><p>From blood-sucking lice and food-stealing gulls to pandemic-inducing viruses and egg-eating snakes: parasites and predators are ubiquitous in shaping ecology and evolution. Fundamental to these interactions is the way in which parasites and predators choose their victim. Here, I argue that a trade-off between host quality and vulnerability can be generalised across systems to understand parasites' choice of hosts. This principle defines quality as the value of resources a host has, and vulnerability as the ease with which a parasite can obtain those resources. A parasite can choose a low-quality host, which is easier to attack but offers limited resources, or a high-quality host, which is more challenging to attack but offers more resources if the parasite is successful. The optimal decision for a parasite will depend on its ecology and the shape of the trade-off in a given system. The trade-off applies equally to predator-prey systems. Many studies of different types of parasitism and predation across taxa have investigated traits pertaining to quality or vulnerability, but their findings have not previously been integrated. Doing so makes it possible to draw out broad principles that determine whether quality or vulnerability has the greater impact on victim choice. It can also help explain contradictory findings, such as why the same antagonists choose high-quality victims in some studies, and low-quality victims in others. Further applications include predicting the effects of global change on host-parasite and predator-prey dynamics, and providing an integrated perspective on coevolutionary adaptations.</p>","PeriodicalId":133,"journal":{"name":"Biological Reviews","volume":" ","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144075055","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}

We then explore the wide range of behaviours suitable for ecotoxicological assessment of APDs (and other neuroactive) pharmaceuticals, principally through laboratory studies with zebrafish, and assess the potential for using these behavioural phenotypes to predict adverse individual- and population-level outcomes in wild fish, taking into account phenotypic plasticity. Next, we illustrate the advantages and challenges of measuring and applying behavioural endpoints for fish, including within current regulatory risk assessments.
