Ecological and biogeographic features shaped the complex evolutionary history of an iconic apex predator (Galeocerdo cuvier)
The tiger shark (Galeocerdo cuvier) is a large iconic marine predator inhabiting worldwide tropical and subtropical waters. So far, only mitochondrial markers and microsatellites studies have investigated its wor... (Source: BMC Evolutionary Biology)

Unparalleled details of soft tissues in a Cretaceous ant
For social insects such as ants, the internal organs are likely important in understanding their eusocial behavior and evolution. Such organs, however, are rarely preserved on fossils. In each of the few cases... (Source: BMC Evolutionary Biology)

Unravelling the palaeobiogeographical history of the living fossil genus Rehderodendron (Styracaceae) with fossil and extant pollen and fruit data
The relict genus Rehderodendron (Styracaceae), the species of which are restricted to mostly warm temperate to tropical climate in East Asia today, is known from fossil fruits and pollen in Europe during warmer p... (Source: BMC Evolutionary Biology)

Response of arboreal Collembola communities to the conversion of lowland rainforest into rubber and oil palm plantations
In the last decades, Southeast Asia has experienced massive conversion of rainforest into rubber and oil palm monoculture plantations. The effects of this land-use change on canopy arthropods are still largely... (Source: BMC Evolutionary Biology)

Cell size, body size and Peto ’s paradox
Carcinogenesis is one of the leading health concerns afflicting presumably every single animal species, including humans. Currently, cancer research expands considerably beyond medicine, becoming a focus in ot... (Source: BMC Evolutionary Biology)

An insight into cancer palaeobiology: does the Mesozoic neoplasm support tissue organization field theory of tumorigenesis?
Neoplasms are common across the animal kingdom and seem to be a feature plesiomorphic for metazoans, related with an increase in somatic complexity. The fossil record of cancer complements our knowledge of the... (Source: BMC Evolutionary Biology)

Allopatric divergence of cooperators confers cheating resistance and limits effects of a defector mutation
Social defectors may meet diverse cooperators. Genotype-by-genotype interactions may constrain the ranges of cooperators upon which particular defectors can cheat, limiting cheater spread. Upon starvation, the... (Source: BMC Evolutionary Biology)

Fruit scent as an honest signal for fruit quality
Fleshy fruits evolved to be attractive to seed dispersers through various signals such as color and scent. Signals can evolve through different trajectories and have various degrees of reliability. The stronge... (Source: BMC Evolutionary Biology)

Evolution of the connectivity and indispensability of a transferable gene: the simplicity hypothesis
The number of interactions between a transferable gene or its protein product and genes or gene products native to its microbial host is referred to as connectivity. Such interactions impact the tendency of th... (Source: BMC Evolutionary Biology)

Evidence for a chemical arms race between cuckoo wasps of the genus Hedychrum and their distantly related host apoid wasps
Brood parasites can exert strong selection pressure on their hosts. Many brood parasites escape their detection by mimicking sensory cues of their hosts. However, there is little evidence whether or not the ho... (Source: BMC Evolutionary Biology)

Modeling the metabolic evolution of mixotrophic phytoplankton in response to rising ocean surface temperatures
Climate change is expected to lead to warming in ocean surface temperatures which will have unequal effects on the rates of photosynthesis and heterotrophy. As a result of this changing metabolic landscape, di... (Source: BMC Evolutionary Biology)
