Abstract We evaluated patterns of species richness, heterogeneity, niche occupation, and community structuring/similarity of staphylinid beetles of the subfamily Steninae across a 2500-m elevational gradient of a tropical mountain area in Northern Thailand. Predaceous Steninae were collected from a variety of habitat types. Increasing Sørensen dissimilarity with increasing elevation was explained by

Abstract The Galápagos Islands are home to incredible endemic biodiversity that is of high conservation interest. Two such endemic species are the Galápagos tomatoes: Solanum cheesmaniae and Solanum galapagense. Both are known from historical location records, but like many endemic plant species on the Galápagos, their current conservation status is unclear. We revisited previously documented sites

Abstract Understanding the mechanisms that drive the assembly of communities is a central goal in ecology, and phylogenetic approaches allows for the testing of hypotheses related to such mechanisms. We analyzed assembly mechanisms of cricetid rodents in an environmentally heterogeneous region of southern Mexico by assessing their phylogenetic diversity and testing environmental predictors of the phylogenetic

Abstract I re-examined the scaling of metabolic rate versus body mass in eight species of ant (static allometry) to illustrate one of the ways by which contemporary concepts of metabolic allometry have been negatively impacted by the widespread use of a standardized procedure for analyzing bivariate data. The procedure in question is the one promoted by Julian Huxley in his monograph on Problems of

Abstract The effect of size-selective predation on prey communities and their traits is well documented, but the relative roles of genetic adaptation and phenotypic plasticity continue to be debated. We looked for evidence of genetic adaption in a population of the water flea Daphnia pulex that faced a novel, introduced predator, Eurasian perch (Perca fluviatilis), selectively preying upon large zooplankton

Abstract The polygyny threshold model predicts that a female chooses an already-mated male if the direct benefits of higher territorial quality compensate for the cost of mate sharing. The sexy son hypothesis (SSH) expands this framework from direct to indirect benefits assuming that polygynously-mated females give birth to sexy and subsequently polygynous sons. Although the SSH has generated much

Abstract This study identifies one possible mechanism whereby gene flow is interrupted in populations undergoing evolutionary divergence in sympatry; this is an important issue in evolutionary biology that remains poorly understood. Variation in trophic morphology was induced in three-spined stickleback by exposing them from an early age either to large benthic or to small pelagic prey. At sexual maturity

Abstract Theory predicts that warning signals should exhibit low variation to increase learning efficiency in predators. Many species, however, exhibit variation in warning colours within species and even within populations. An understudied example of within species variation is that between life stages, where animals change warning colouration throughout ontogeny. Understanding how warning signals

Abstract Detailed behavioral observations of the same urban population of Water Dragons (Intellagama lesueurii) during two reproductive periods 7 years apart (2009 vs. 2016) revealed a dramatic change in aggression and the social context of male displays. Differences in the behavior of 2016 males may be a consequence of increased visibility of conspecifics due to anthropogenic removal of vegetation

Abstract Seed mass is a main determinant of seedling establishment, particularly under stressful conditions, as bigger seeds offer more resources to the emerging seedling. This has led to the expectation of increased seed mass under harsh conditions. Here, we studied the role of different components of environmental harshness on the evolution of seed size in Pinus. We assessed whether differences in

Abstract Sequential hermaphroditism (sex change) is understood to be a strategy that maximizes lifetime reproduction in systems where one sex confers highest fitness early in life, and the other later in life. This strategy is evolutionarily stable despite costs to growth, survival, or current reproduction. Few studies have examined advantages of sex change outside of reproduction. The mangrove rivulus

Abstract Speciation is nowadays recognized as a dynamic process in which the respective roles of forces driving ecological differentiation and reproductive isolation can change through time and space. Incipient speciation events are particularly useful to follow such processes that are not tractable when considering well-differentiated taxa. A promising case study was discovered in the pine processionary

Abstract Haplotilapiine are members of Cichlidae (cichlid fishes), one of the most species-rich vertebrate families. Many haplotilapiines diversified via allopatric divergence, sexual selection, hybridization and ecological adaptation, making them excellent models for evolutionary research. One extraordinary example of how haplotilapiine diversified are the species found within the Sahara desert, surviving

Abstract Diapause in seasonal environments allows insects to survive adverse seasons. However, individuals can sometimes enter a prolonged diapause for more than a year, and also skip favourable seasons, which can bring additional costs through e.g. loss of metabolic resources. At the same time, prolonged diapause can be beneficial if it allows individuals to have a risk-spreading strategy to skip

Abstract Using species ranges, in particular those derived from species distribution models (SDM), to obtain characteristics of the species’ niche such as temperature tolerances is tempting. Over the past decade the literature has seen the increase in the use of SDMs based on locality data and spatially explicit datasets (climate, vegetation etc.). Furthermore, several studies have explored climatic

Abstract Mitochondria are sensitive to oxidative stress, including that derived from ionizing radiation. To quantify the effects of exposure to environmental radionuclides on mitochondrial DNA (mtDNA) dynamics in wildlife, bank voles (Myodes glareolus) were collected from the chernobyl exclusion zone (CEZ), where animals are exposed to elevated levels of radionuclides, and from uncontaminated areas

Abstract The evolutionary spread of a trait that benefits individuals of one species in their interactions with a second species may be constrained by “ecological costs” if the trait also has detrimental effects on interactions with a third species in the environment. In particular, the identification of ecological costs may help explain why natural plant populations often display less-than-maximal

Abstract Anthropogenic disturbance has the potential to influence metapopulation dynamics by altering habitat quality and connectivity. In particular, species with limited vagility and specific habitat preferences, such as the Florida scrub lizard (Sceloporus woodi), are likely to be affected by landscape-altering events. In the Ocala National Forest (ONF) of central Florida, subpopulations of Florida

Abstract Antimicrobial resistance (AMR) is widespread, with resistant pathogens found not only in the clinic but throughout the natural and built environments. It is unclear, however, to what extent AMR should be expected to persist in the environment: Laboratory experiments have suggested that resistance is typically costly, and hence should be selected against. However, such studies may not generalize

Parents can influence offspring dispersal through breeding site selection, competition, or by directly moving their offspring during parental care. Many animals move their young, but the potential role of this behavior in dispersal has rarely been investigated. Neotropical poison frogs (Dendrobatidae) are well known for shuttling their tadpoles from land to water, but the associated movements have

Niche construction refers to the modification of selective environments by organisms. Theoretical and empirical studies of niche construction are increasing in importance as foci in evolutionary ecology. This special edition presents theoretical and empirical research that illustrates the significance of niche construction to the field. Here we set the scene for the following papers by (1) discussing

Social immunity refers to any immune defence that benefits others, besides the individual that mounts the response. Since contributions to social immunity are known to be personally costly, they are contributions to a public good. However, individuals vary in their contributions to this public good and it is unclear why. Here we investigate whether they are responding to contributions made by others

Unicellular eukaryotes, or protists, are among the most ancient organisms on Earth. Protists belong to multiple taxonomic groups; they are widely distributed geographically and in all environments. Their ability to discriminate among con- and heterospecifics has been documented during the past decade. Here we discuss exemplar cases of taxa-, clone-, and possible kin-discrimination in five major lineages:

In this paper we examine the effect of reproductive interference on the dynamics of two mosquito vectors of public health concern and add to the growing literature on the strength and speed with which interspecific reproductive interference may drive evolution. Recent evidence supports a role for asymmetric reproductive interference, or satyrization, in competitive displacements of Aedes aegypti by

It has been suggested that mating behaviours require high levels of cognitive ability. However, since investment into mating and the brain both are costly features, their relationship is likely characterized by energetic trade-offs. Empirical data on the subject remains equivocal. We investigated if early sexual maturation was associated with brain development in Atlantic salmon (Salmo salar), in which

In a previous study, we showed that Spiroplasma, a maternally transmitted endosymbiotic bacterium of Drosophila hydei, enhances larval to adult survival of its host when exposed to oviposition attack by the parasitoid wasp Leptopilina heterotoma. The mechanism by which Spiroplasma enhances host survival has not been elucidated. To better understand this mechanism, we compared the growth of wasp larvae

Interspecific mating normally decreases female fitness. In many species, females avoid heterospecific males innately or by imprinting on their parents. Alternatively, adult females could learn to discriminate against heterospecific males after exposure to such males. For example, Syrian hamster (Mesocricetus auratus) females learn to discriminate between conspecific males and Turkish hamster (M. brandti)
