Architecture of Dispatched, a Transmembrane Protein Responsible for Hedgehog Release.

Front Mol Biosci 2021 7;8:701826. Epub 2021 Sep 7.

CAS Center for Excellence in Molecular Cell Science, Shanghai Institute of Biochemistry and Cell Biology, University of Chinese Academy of Sciences, Chinese Academy of Sciences, Shanghai, China.

The evolutionarily conserved Hedgehog (Hh) signaling pathway is crucial for programmed cell differentiation and proliferation. Dispatched (Disp) is a 12-transmembrane protein that plays a critical role in the Hedgehog (Hh) signaling pathway by releasing the dually lipidated ligand HhN from the membrane, a prerequisite step to the downstream signaling cascade. In this study, we focus on the Disp from water bear, a primitive animal known as the most indestructible on Earth. Read More

Refocusing multiple stressor research around the targets and scales of ecological impacts.

Nat Ecol Evol 2021 Sep 23. Epub 2021 Sep 23.

Department of Animal and Plant Sciences, University of Sheffield, Sheffield, UK.

Ecological communities face a variety of environmental and anthropogenic stressors acting simultaneously. Stressor impacts can combine additively or can interact, causing synergistic or antagonistic effects. Our knowledge of when and how interactions arise is limited, as most models and experiments only consider the effect of a small number of non-interacting stressors at one or few scales of ecological organization.

Species co-occurrence and management intensity modulate habitat preferences of forest birds.

BMC Biol 2021 Sep 23;19(1):210. Epub 2021 Sep 23.

Chair of Wildlife Ecology and Management, University of Freiburg, Tennenbacher Str. 4, 79106, Freiburg, Germany.

Background: Species co-occurrences can have profound effects on the habitat use of species, and therefore habitat structure alone cannot fully explain observed abundances. To account for this aspect of community organization, we developed multi-species abundance models, incorporating the local effect of co-occurring and potentially associated species, alongside with environmental predictors, linked mainly to forest management intensity. We coupled it with a landscape-scale analysis to further examine the role of management intensity in modifying the habitat preferences in connection with the landscape context. Read More

Trophic relationships between the crab Libinia ferreirae and its symbionts.

Mar Environ Res 2021 Sep 17;171:105479. Epub 2021 Sep 17.

Group of Studies on Crustacean Biology, Ecology and Culture (NEBECC), Department of Zoology, Institute of Biosciences, São Paulo State University (UNESP), 18618-970, Botucatu, São Paulo, Brazil.

Symbioses are ubiquitous in the animal kingdom. However, in most cases, the role of each member is relatively fixed, and it is rare for the same species to exhibit different symbiotic behaviours throughout its ontogeny. Here, we use stable isotope analyses of food resources to identify the relationships between the spider crab Libinia ferreirae as a symbiont of its jellyfish host during juvenile life stages and as a host for sea anemone epibionts on its carapace as an adult.

To cope with a changing aquatic soundscape: neuroendocrine and antioxidant responses to chronic noise stress in fish.

Gen Comp Endocrinol 2021 Sep 20:113918. Epub 2021 Sep 20.

Institute of Marine Biology, National Taiwan Ocean University.

Anthropogenic underwater noises that change aquatic soundscapes represent an important issue in marine conservation. While it is evident that strong underwater acoustic pollutants may cause significant damage to fish at short ranges, the physiological effects of long-term exposure to relatively quiet but continuous noise are less well understood. Here, we present a summary of the known impacts of long-term underwater noise on hypothalamic-pituitary-interrenal (HPI) axis-mediated physiological responses, oxidant/antioxidant balance, and neurotransmitter regulation in fish.

Use of RNAi With as a Reporter for Candidate Genes Can Efficiently Create and Verify Gametophytic Male Sterility in Rice.

Front Plant Sci 2021 6;12:728193. Epub 2021 Sep 6.

State Key Laboratory for Conservation and Utilization of Bio-Resources in Yunnan, Research Center for Perennial Rice Engineering and Technology in Yunnan, School of Agriculture, Yunnan University, Kunming, China.

Gametophytic male sterility (GMS) plays an important role in the study of pollen development and seed propagation of recessive nuclear male sterile lines insensitive to the environmental conditions in hybrid rice breeding. Since the inherent phenotypic and genetic characteristics of GMS, it is very difficult to find and identify the GMS mutants. However, due to the abundance of gene transcription data, a large number of pollen-specific genes have been found, and most of them may be associated with GMS. Read More

COVID-19, media coverage of bats and related Web searches: a turning point for bat conservation?

Mamm Rev 2021 Jun 27. Epub 2021 Jun 27.

Dipartimento di Scienze della Vita e Biologia dei Sistemi Università degli Studi di Torino Via Accademia Albertina 13 10123 Torino Italy.

SARS-CoV-2, the virus that caused the COVID-19 pandemic, is genomically similar to a SARS-like beta-coronavirus found in Asian rhinolophid bats. This evolutionary relationship impressed the global media, which then emphasised bats as key actors in the spillover that resulted in the pandemic. In this study, we highlight changes in the traditional and new media coverage of bats and in Internet search volumes that occurred since the beginning of the COVID-19 pandemic in 2020. Read More
