An inordinate fondness for slugs: Phylogenomics of the diverse gastropod clade Heterobranchia, a group key to our understanding of the evolution of shell reduction and loss
(2022-03-17)Gastropods are exquisitely successful organisms, their shell undoubtedly playing a key role in their success. Despite being such an effective defense mechanism, the gastropod shell has been reduced, lost or internalized ... -
Analyzing The Evolution and Diversification of Lepidoptera Using Multi-Spectral Images
(2023-06-01)Insects comprise an estimated 60% of all described species, and butterflies are among the best known of all insect taxa. The order Lepidoptera (butterflies and moths) contains approximately 160,000 species in 126 families. ... -
Character displacement and community assembly in Anolis lizards
(2013-10-08)At broad scales, community ecologists study how biogeographic factors like environmental dissimilarity and geographic distance influence community assembly and composition. At small scales, community ecologists study how ... -
Comparative Genomics of the Major Histocompatibility Complex in Amniotes
(2013-03-18)The major histocompatibility complex region (MHC) is a multi gene family present in all jawed vertebrates, with a fundamental role in vertebrate immunity. More than two decades of studies have resulted in the characterization ... -
Competition, Character Displacement, and Ecological Release in Anolis lizards
(2021-09-01)The addition or subtraction of species in a community can alter the ecology and evolution of resident species. As human-mediated introductions and extinctions have become commonplace, understanding the consequences of ... -
Development and evolution of the larval stomach of the Budgett’s Frog, Lepidobatrachus laevis
(2023-09-06)Anurans have a highly conserved biphasic life history with morphologically- and ecologically- divergent tadpole and adult phases. Tadpoles are typically aquatic, filter-feeding herbivores that transform dramatically during ... -
Development in the acoel Hofstenia miamia and the embryonic origins of stem cells
(2022-06-06)Many animals across the metazoan tree of life are capable of whole-body regeneration, or the regeneration of entire body axes. Notably, whole body regeneration is often mediated by a population of pluripotent stem cells ... -
Developmental and evolutionary origins of the crocodylian snout and amniote face
(2020-11-23)Crocodylians (alligators, crocodiles, and gharial) are instantly recognizable by their flattened skulls and tooth-filled jaws, adaptations which aid in capturing prey in shallow water and along riverbanks. A popular ... -
Developmental mechanisms underlying avian morphological evolution
(2023-05-12)Vertebrates have evolved remarkable morphological diversity over millions of years, from the smallest hummingbird to the largest whales, in response to natural selection. These endless forms, generated over the course of ... -
Divergence and diversity in rapidly evolving populations
(2020-11-23)Models in theoretical population genetics and evolutionary dynamics seek to connect the underlying forces of mutation, selection and genetic drift to observable patterns of phenotypic and/or genotypic variation. To do so, ... -
Early germ line development in the hemipteran insect Oncopeltus fasciatus
(2022-09-12)The cell lineage that forms eggs and sperm is referred to as the germ line, and the integrity of this cell lineage is critical for the successful reproduction and the survival of a species. The earliest progenitors of the ... -
Ecology and evolution of the African ant acacia, Vachellia drepanolobium, and its multiple symbionts
(2021-05-14)Ant-plants provide food rewards and housing for resident ant colonies, and in exchange, the workers protect their host plant from herbivores and pathogens. The specific outcomes of these symbioses are highly context-dependent, ... -
Ecology and Evolution Within the Oral Microbiome
(2021-07-12)Bacteria inhabit every known ecosystem, from deep-sea hydrothermal vents to plant surfaces. The human body represents one such microbially-dominated ecosystem with the identity and function of human-associated microbiota ... -
Energy Allocation to Skeletal Muscle After Physical Activity: The Role of Interleukin-6
(2023-09-08)Interleukin-6 (IL-6) is a multifunctional cytokine with disparate and often contradictory effects. A superficial explanation for this functional diversity is that IL-6 is highly context-dependent and performs a different ... -
Epistasis, Pleiotropy, and Evolutionary Dynamics
(2021-07-12)The advent of technologies for expedient nucleic acid sequencing, synthesis, assembly, and editing has opened up new vistas for exploring the genetic causes and consequences of evolutionary dynamics. In particular, it has ... -
The Evolution and Development of Inequity Aversion
(2013-10-08)Humans show such strong sensitivity to whether resources are distributed fairly that they sacrifice personal gain to avoid distributional inequity. This inequity aversion plays an important role in guiding human social ... -
The evolution and development of the archosaurian head and the origin of the bird skull
(2014-06-06)Abstract: Archosauria, the "ruling reptiles," characterized along their stem by relatively large, macrocarnivorous animals, are today represented by two enormously successful but divergent extant clades: Aves, the birds, ... -
Evolution of Bivalvia: Multi-level phylogenetic and phylogenomic reconstructions within Bivalvia (Mollusca) with emphasis on resolving familial relationships within Archiheterodonta (Bivalvia: Heterodonta).
(2013-10-15)With an estimated 8,000-20,000 species, bivalves represent the second largest living class of molluscs (Bieler et al. 2013). Revived interest in molluscan phylogeny has resulted in a torrent of molecular sequence data from ... -
Evolution of Morphology: Modifications to Size and Pattern
(2014-06-06)A remarkable property of developing organisms is the consistency and robustness within the formation of the body plan. In many animals, morphological pattern formation is orchestrated by conserved signaling pathways, through ... -
Evolutionary Adaptation and Antimalarial Resistance in Plasmodium falciparum
(2013-10-14)The malaria parasite, Plasmodium falciparum, has a demonstrated history of adaptation to antimalarials and host immune pressure. This ability unraveled global eradication programs fifty years ago and seriously threatens ...
