(Frontiers Media, 2014-09-26)Over the last several decades, the distribution of the black mangrove Avicennia germinans in the Gulf of Mexico has expanded, in part because it can survive the occasional freeze events and high soil salinities characteristic ...

Defining the Role of Operational Sex Ratio in Fitness of Organisms With Sexually Antagonistic Genes (2020-04-23)In many species, populations vary in size and reproductive sex ratio, producing situations in which small population sizes are paired with strongly skewed effective sex ratios. This imbalance among sexes is particularly ...
-
(2013-02-04)In addition to their primary biological function, many proteins are at least moderately capable of catalyzing secondary, promiscuous activities that may have a major role in enzyme evolution. Mounting evidence supports the ...
-
(2011-10-21)The Pezizomycotina, commonly known as the filamentous fungi, are a diverse group of organisms that have a major impact on human life. The filamentous fungi diverged from a common ancestor approximately 200 – 700 million ...
-
(Texas A&M University, 2006-04-12)Transmissible spongiform encephalopathies (TSEs), or prion diseases, are a group of inevitably fatal neurodegenerative diseases that occur in mammalian species. Ovine susceptibility to scrapie, the prototypical TSE, is ...
-
(2010-07-14)Most of genes contained in a genome have been shown to exist in forms of families; however, little is known about their variation and evolution during the course of genome evolution. The present study shows that the numbers ...
-
(2016-10-07)Parasitic chewing lice (Insecta: Phthiraptera) of birds are found everywhere their avian hosts are distributed, and their host relationships and taxonomy have been well studied in many regions. Lice have obligate parasitic ...
-
(Oxford University Press, 2001)This is an overview of theories of humor's adaptive significance.
-
(2011-02-22)The amidohydrolase superfamily is a functionally diverse group of evolutionarily related proteins which utilize metal cofactors in the activation of a hydrolytic water molecule and in the stabilization of the resulting ...
-
(2014-04-25)Myoglobin (Mb) is an oxygen binding hemoprotein in vertebrate skeletal muscle that functions in intracellular oxygen storage and transport. Due to the unique oxygen storage demands of diving birds and mammals, these ...
-
(2017-04-27)The family Myrmeleontidae, or antlions, is considered today as the largest family of the order Neuroptera. This cosmopolitan group comprises more than 1600 valid species and nearly 200 genera. The taxonomy of the family ...
-
(2014-04-16)Adaptive laboratory evolution (ALE) is a powerful tool for strain improvement, and has been applied successfully to improve a range of desirable phenotypes in model organisms through continuous cultivation under a selective ...
-
(2015-08-13)Plant innate immunity has been classified into two layers of defense systems. Nucleotide-binding domain leucine-rich repeat (NLR) protein complexes activated by pathogen effectors launches effector-triggered immunity (ETI). ...
-
(2012-07-16)The presence of metaphorical language in Charles Darwin's On the Origin of Species has been the source of much debate, particularly in the interaction between Darwin's theory and the Christian faith. The metaphorical ...
-
(2021-07-27)Only a small species of Culicoides midges are pathogen vectors in both managed and natural systems, and as such, proper species delimitation is vital. Before this study, the C. variipennis species complex contained three ...
-
(2018-11-26)The colony-forming green microalga Botryococcus braunii is mostly known for its ability to produce an abundance of liquid hydrocarbons. However, geochemical studies have found fossilized remains of the species in petroleum ...
-
(2020-06-10)The factors that enable enzymes to evolve new functions and specificities are not well understood. Two factors that influence enzyme evolution are enzyme promiscuity and epistasis. Enzymes are said to be promiscuous if ...
-
(2012-12-10)Understanding how protein sequence, structure and function coevolve is at the core of functional genome annotation and protein engineering. The fundamental problem is to determine whether sequence variation contributes to ...
-
(2017-12-12)The 27 flightless grasshopper species of the Puer Group (Orthoptera: Acrididae: Melanoplinae: Melanoplus) comprise a biological system of fascinating complexity in the southeastern U.S.A. that was heavily influenced by sea ...
