Intron losses and gains in the nematodes
BackgroundThe evolution of spliceosomal introns has been widely studied among various eukaryotic groups. Researchers nearly reached the consensuses...
-
Temperate species underfill their tropical thermal potentials on land
Understanding how temperature determines the distribution of life is necessary to assess species’ sensitivities to contemporary climate change. Here,...

Ecophysiological differentiation between life stages in filmy ferns (Hymenophyllaceae)
Desiccation tolerance was a key trait that allowed plants to colonize land. However, little is known about the transition from desiccation tolerant...
-
Heterogeneous relationships between rates of speciation and body size evolution across vertebrate clades
Several theories predict that rates of phenotypic evolution should be related to the rate at which new lineages arise. However, drawing general...

Sexual size dimorphism and its allometry in Chinese lizards
Rensch's rule is an allometric rule on sexual size dimorphism. It states that in small-sized species, females are larger than males, whereas in...
-
Climate drives global functional trait variation in lizards
A major challenge in ecology and evolution is to disentangle the mechanisms driving broad-scale variation in biological traits such as body size,...
-
Social insect colony size is correlated with rates of molecular evolution
Larger numbers of germline cell divisions can increase the number of mutations inherited by offspring. Therefore, in systems where the number of...

Comparative genomics reveals molecular mechanisms underlying health and reproduction in cryptorchid mammals
BackgroundMammals have wide variations in testicular position, with scrotal testes in some species and ascrotal testes in others. Although...

Clutch size and the rejection of parasitic eggs: a comparative test of the maternal investment hypothesis
Obligate brood parasitic birds lay their eggs in the nests of other species, reducing the host’s own reproductive output. To circumvent these fitness...

A Morphological Method to Approximate Jum** Performance in Anurans for Macroevolutionary Studies
Organismal performance is often key in understanding macroevolutionary patterns but characterizing performance across many species is challenging, as...

Habitat influences skeletal morphology and density in the snailfishes (family Liparidae)
We tested the hypothesis that deep-sea fishes have poorly mineralized bone relative to shallower-dwelling species using data from a single family...
-
Plasma methionine metabolic profile is associated with longevity in mammals
Methionine metabolism arises as a key target to elucidate the molecular adaptations underlying animal longevity due to the negative association...
-
Habitat characteristics and life history explain reproductive seasonality in lagomorphs
Lagomorphs show extensive seasonal variation in their reproduction. However, the factors causing this large variation have so far mostly been...
-
Incorporating indirect pathways in body size–trophic position relationships
Body size, trophic position (TP), and trophic niche width are important elements of food webs; however, there is still debate regarding their...

Elevated metallothionein expression in long-lived species mediates the influence of cadmium accumulation on aging
Cadmium (Cd) accumulates with aging and is elevated in long-lived species. Metallothioneins (MTs), small cysteine-rich proteins involved in metal...
-
Morphological complexity affects the diversity of marine microbiomes
Large eukaryotes support diverse communities of microbes on their surface—epibiota—that profoundly influence their biology. Alternate factors known...
-
Evolutionary allometry of sexual dimorphism of jum** performance in anurans
Sexual dimorphism is a common feature in animals, yet the degree of sexual dimorphism is not constant across taxa. Sometimes the magnitude of sexual...

The impact of locomotion on the brain evolution of squirrels and close relatives
How do brain size and proportions relate to ecology and evolutionary history? Here, we use virtual endocasts from 38 extinct and extant rodent...
-
Vertebrate host phylogeny influences gut archaeal diversity
Commonly used 16S rRNA gene primers do not detect the full range of archaeal diversity present in the vertebrate gut. As a result, several questions...

Small interannual variability in the body mass of a seabird with high flight costs
Seabird parents during chick rearing is hypothesized to regulate body mass to reduce flight costs and invest energy in current reproduction. Alcids...
