Fitness trade-offs and the origins of endosymbiosis
by Michael A. Brockhurst, Duncan D. Cameron, Andrew P. Beckerman
Endosymbiosis drives evolutionary innovation and underpins the function of diverse ecosystems. The mechanistic origins of symbioses, however, remain unclear, in part because early evolutionary events are obscured by subsequent evolution and genetic drift. This Essay highlights how experimental studies of facultative, host-switched, and synthetic symbioses are revealing the important role of fitness trade-offs between within-host and free-living niches during the early-stage evolution of new symbiotic associations. The mutational targets underpinning such tra...

Fungal holobionts as blueprints for synthetic endosymbiotic systems
by Laila P. Partida-Mart ínez
Rhizopus microsporus is an example of a fungal holobiont. Strains of this species can harbor bacterial and viral endosymbionts inherited by the next generation. These microbial allies increase pathogenicity and defense and control asexual and sexual reproduction.

Realism and robustness require increased sample size when studying both sexes
by Szymon M. Drobniak, Malgorzata Lagisz, Yefeng Yang, Shinichi Nakagawa
A recent article claimed that researchers need not increase the overall sample size for a study that includes both sexes. This Formal Comment points out that that study assumed two sexes to have the same variance, and explains why this is a unrealistic assumption. (Source: PLoS Biology: Archived Table of Contents)

Interpreting population- and family-based genome-wide association studies in the presence of confounding
by Carl Veller, Graham M. Coop
A central aim of genome-wide association studies (GWASs) is to estimate direct genetic effects: the causal effects on an individual ’s phenotype of the alleles that they carry. However, estimates of direct effects can be subject to genetic and environmental confounding and can also absorb the “indirect” genetic effects of relatives’ genotypes. Recently, an important development in controlling for these confounds has been the use of within-family GWASs, which, because of the randomness of mendelian segregation within pedigrees, are often interpreted as producing unbiased estimates of ...

Molecular circadian rhythms are robust in marine annelids lacking rhythmic behavior
by N. S ören Häfker, Laurenz Holcik, Audrey M. Mat, Aida Ćorić, Karim Vadiwala, Isabel Beets, Alexander W. Stockinger, Carolina E. Atria, Stefan Hammer, Roger Revilla-i-Domingo, Liliane Schoofs, Florian Raible, Kristin Tessmar-Raible
The circadian clock controls behavior and metabolism in various organisms. However, the exact timing and strength of rhythmic phenotypes can vary significantly between individuals of the same species. This is highly relevant for rhythmically complex marine environments where organismal rhythmic diversity likely permits the occupation of different microenvironments. When investigating circ...

Linking cell biology and ecology to understand coral symbiosis evolution
by Niels J. Dingemanse, Annika Guse
Understanding the evolution of coral endosymbiosis requires a predictive framework that integrates life-history theory and ecology with cell biology. The time has come to bridge disciplines and use a model systems approach to achieve this aim.

Modeling endosymbioses: Insights and hypotheses from theoretical approaches
by Lucas Santana Souza, Josephine Solowiej-Wedderburn, Adriano Bonforti, Eric Libby
Endosymbiotic relationships are pervasive across diverse taxa of life, offering key avenues for eco-evolutionary dynamics. Although a variety of experimental and empirical frameworks have shed light on critical aspects of endosymbiosis, theoretical frameworks (mathematical models) are especially well-suited for certain tasks. Mathematical models can integrate multiple factors to determine the net outcome of endosymbiotic relationships, identify broad patterns that connect endosymbioses with other systems, simplify biological complexity, ge...

Symbiotic revolutions at the interface of genomics and microbiology
by John M. Archibald
Symbiosis is an old idea with a contentious history. New genomic technologies and research paradigms are fueling a shift in some of its central tenets; we need to be humble and open-minded about what the data are telling us.

Symbiosis takes a front and center role in biology
by Margaret McFall-Ngai
All animals and plants likely require interactions with microbes, often in strong, persistent symbiotic associations. While the recognition of this phenomenon has been slow in coming, it will impact most, if not all, subdisciplines of biology.

Chaperone Hsp70 helps < i > Salmonella < /i > survive infection-relevant stress by reducing protein synthesis
by Carissa Chan, Eduardo A. Groisman
In all domains of life, Hsp70 chaperones preserve protein homeostasis by promoting protein folding and degradation and preventing protein aggregation. We now report that the Hsp70 from the bacterial pathogenSalmonella enterica serovar Typhimurium —termed DnaK—independently reduces protein synthesis in vitro and inS. Typhimurium facing cytoplasmic Mg2+ starvation, a condition encountered during infection. This reduction reflects a 3-fold increase in ribosome association with DnaK and a 30-fold decrease in ribosome association with trigger factor, the chaperone normally associated wi...

What choanoflagellates can teach us about symbiosis
by Arielle Woznica
Environmental bacteria influence many facets of choanoflagellate biology, yet surprisingly few examples of symbioses exist. We need to find out why, as choanoflagellates can help us to understand how symbiosis may have shaped the early evolution of animals.
Environmental bacteria influence many facets of choanoflagellate biology, yet surprisingly few examples of symbioses exist. This Perspective explores why choanoflagellates are an exciting system for enriching our understanding of eukaryote-bacteria symbioses and for considering how symbiotic associations with bacteria may shaped the early evolution ...

Shortcut citations in the methods section: Frequency, problems, and strategies for responsible reuse

Methods sections are often missing essential details. Methodological shortcut citations, in which authors cite previous papers instead of describing the method in detail, may contribute to this problem. This meta-research study used 3 approaches to examine shortcut citation use in neuroscience, biology, and...

Visual perception of highly memorable images is mediated by a distributed network of ventral visual regions that enable a late memorability response
by Benjamin Lahner, Yalda Mohsenzadeh, Caitlin Mullin, Aude Oliva
Behavioral and neuroscience studies in humans and primates have shown that memorability is an intrinsic property of an image that predicts its strength of encoding into and retrieval from memory. While previous work has independently probed when or where this memorability effect may occur in the human brain, a description of its spatiotemporal dynamics is missing. Here, we used representational similarity analysis (RSA) to combine functional magnetic resonance imaging (fMRI) with source-estimated magnetoencephalography (MEG) to simultaneously measure when a...
