Stem photosynthetic efficiency across woody angiosperms and gymnosperms with contrasting drought tolerance
Key messageStem photosynthesis seems to play an adaptive role for woody plants that prosper in hot and dry ecosystems.
AbstractStem photosynthesis...

The Evolution of Brain Size in Ectothermic Tetrapods: Large Brain Mass Trades-Off with Lifespan in Reptiles
The evolution of brain size is constrained by the trade-off between the energetic costs allocated towards its maintenance and the cognitive...

Sizing up swords: Correlated evolution of antlers and tusks in ruminants
Many sexual weapons used in sexual combat and/or as visual displays of dominance (e.g., antlers, horns) show positive allometry with body size, but...
-
Inconsistent results from trait-based analyses of moth trends point to complex drivers of change
Trait-based approaches are advocated for their ability to predict population declines in data-deficient taxa and regions, potentially benefiting...

Leaf toughness is a better predictor of herbivory and plant performance than leaf mass per area (LMA) in temperate evergreens
The mechanical strengthening of leaves protects seedlings from herbivore damage, particularly in shade-tolerant evergreens. Interspecific studies...

Significant effects of host dietary guild and phylogeny in wild lemur gut microbiomes
Mammals harbor diverse gut microbiomes (GMs) that perform critical functions for host health and fitness. Identifying factors associated with GM...

Does microhabitat use affect population differentiation? A test with southwestern Palaearctic forest birds
We tested whether microhabitat use affects dispersal and population differentiation in forest birds of the southwestern Palaearctic, a link...

The impact of environmental factors on the evolution of brain size in carnivorans
The reasons why some animals have developed larger brains has long been a subject of debate. Yet, it remains unclear which selective pressures may...

How to weigh a fossil mammal? South American notoungulates as a case study for estimating body mass in extinct clades
Body mass (BM) is a fundamental variable for many paleobiological investigations that is challenging to accurately infer for species that lack living...

Patterns in Body Size
We discuss several patterns and processes related to body size variation in this chapter. Body size is one of the most important macroecological...

Divergent vertebral formulae shape the evolution of axial complexity in mammals
Complexity, defined as the number of parts and their degree of differentiation, is a poorly explored aspect of macroevolutionary dynamics. The...

The Predictable Complexity of Evolutionary Allometry
Allometry has been a paradigm of constraints, including intrinsic constraints on the evolvability of allometry, as a source of developmental and...

Competition for epidermal area, instead of coordination, between stomata and vein patterns in Ficus (Moraceae) with different growth forms
The coordination of stomatal conductance and hydraulic conductance in plants is often indicated by a positive relationship between stomatal density...

Ecology impacts the decrease of Spirochaetes and Prevotella in the fecal gut microbiota of urban humans
Compared to the huge microbial diversity in most mammals, human gut microbiomes have lost diversity while becoming specialized for animal-based diets...

Environmental niche and flight intensity are associated with molecular evolutionary rates in a large avian radiation
BackgroundMetabolic activity and environmental energy are two of the most studied putative drivers of molecular evolutionary rates. Their extensive...

Avialan-like brain morphology in Sinovenator (Troodontidae, Theropoda)
Many modifications to the skull and brain anatomy occurred along the lineage encompassing non-avialan theropod dinosaurs and modern birds. Anatomical...
-
Emergence and influence of sequence bias in evolutionarily malleable, mammalian tandem arrays
BackgroundThe radiation of mammals at the extinction of the dinosaurs produced a plethora of new forms—as diverse as bats, dolphins, and elephants—in...

Lentic and lotic environments affect morphological diversity in characiformes fishes in the Neotropical São Francisco River Basin, Brazil
The order Characiformes is one of the most diverse and widely distributed groups of fishes in cis-Andean basins. That diversity is reflected in the...

Online repositories of photographs and videos provide insights into the evolution of skilled hindlimb movements in birds
The ability to manipulate objects with limbs has evolved repeatedly among land tetrapods. Several selective forces have been proposed to explain the...

Evolution of the bovid cranium: morphological diversification under allometric constraint
The role of environmental selection in generating novel morphology is often taken for granted, and morphology is generally assumed to be adaptive....
