Hyblaea puera (Lepidoptera: Hyblaeidae), is considered as a serious pest of teak in India and other tropical regions. It causes entire defoliation of teak trees and results in huge timber loss thereby decreasing forest productivity. Hyblaea puera Nucleopolyhedrovirus...

Rugose Corals, often referred to as Horn Coral, are an extinct order of stony corals in the phylum Cnidaria. They lived from the Ordivician period to the end of the Permian period, and can be found worldwide. A new fossil of Siphonophrentis gigantea, a species...

Open-ended evolution researchers seek to create systems that continually produce new evolutionary outcomes, attempting to reflect the power and diversity of evolution in nature. The specific metrics used (novelty, complexity, diversity, etc) vary by researcher,...

Background. Understanding genetic diversity and population structure is critically important for the conservation and management of endangered species. These factors are particularly relevant for species with small populations and/or restricted ranges, such as...

Speciation processes have long been inferred from phylogenetic, phylogeographic, and biogeographic pattern-driven perspectives. Now much current speciation research is attempting to more directly describe the underlying processes and mechanisms of divergence leading...

Paternity uncertainty has proven to be a robust ultimate hypothesis for predicting the higher investment in grandchildren observed among maternal grandparents compared to that of the paternal grandparents. Yet, the proximate mechanisms for generating such preferred...

We aimed to examine mechanistically the observed foraging differences across two honey bee, Apis mellifera, subspecies using the Proboscis Extension Response (PER) assay. Specifically, we compared differences in appetitive reversal learning ability between honey...

Amphibians are the most vulnerable vertebrates to biodiversity loss mediated by habitat destruction, climate change and diseases. Informed conservation management requires to improve the taxonomy of anurans to assess reliably the species´ geographic range. In this...

Background. Following recent advances in bioimaging, high-resolution 3D models of biological structures are now generated rapidly and at low-cost. To utilise this data to address evolutionary and ecological questions, an array of tools has been developed to conduct...

A productive biosphere and oxygenated atmosphere are defining features of Earth and are fundamentally linked. Here I argue that cellular metabolism imposes central constraints on the historical trajectories of biopsheric productivity and atmospheric oxygenation....

Landscape composition and structure influence animal movement, which in turn can affect transmission of their diseases. Spatio-temporal variation in host diffusion, caused by landscape heterogeneity, is thus expected to generate corresponding phylogeographic patterns...

The ability of certain natural species to restore or regenerate missing structures has been a recurrent source of inspiration to forge our collective knowledge, from being used to adorn mythological figures with superhuman powers to permitting controlled reproducible...

Background: It is estimated that 13% of arthropod species carry the heritable symbiont Cardinium hertigii. 16S rRNA and gyrB sequence divides this species into three clades, with the A group infecting a range of arthropods, the B group infecting nematode worms,...

The oldest feathers known to date have been found in archosaurs capable to fly. However, some of them (scansoriopterygids) flied by the use of a membrane rather than feathers. We therefore propose a new mechanism for the origin of avian flight by the use of membranous...

Birds are unique among extant tetrapods in having pneumatic diverticula of the lungs and air sacs that pass among the viscera and muscles, under the skin, and into the skeleton. In addition, some birds also have supramedullary diverticula inside the neural canal,...
