Breeding History of Three Mega Rice (Oryza sativa L.) Varieties (BR11, BRRI dhan28, BRRI dhan29) of Bangladesh – A Review
Published: 2023-11-17
Subjects: Life Sciences
Rice is a staple food consumed by billions of people worldwide, particularly in Asia. However, outdated rice cultivars and poor cultivar replacement have led to a decline in rice productivity in Bangladesh. To address this, the Bangladesh Rice Research Institute (BRRI) developed three mega rice varieties: BR11, BRRI dhan28, and BRRI dhan29. BR11 is a popular Transplanted Aman (T. Aman) rice [...]
The Pest Management Attitude scale: a tool for measuring consensus between experts and practitioners in invasion biology
Published: 2023-11-17
Subjects: Life Sciences, Other Anthropology, Other Psychology, Psychology, Social and Behavioral Sciences, Systems Biology
Quantifying attitudes towards invasive alien species (IAS) is fundamental to understand the extent to which conservation scientists agree and can collaborate in their management. We tested the Pest Management Scale (PMS), originally invented to quantify attitudes towards invasive alien mammals in New Zealand, as a tool to quantify broader attitudes towards IAS among bioinvasion experts in [...]
Inferring diet, disease, and antibiotic resistance from the ancient oral microbiome
Published: 2023-11-17
Subjects: Bacteriology, Computational Biology, Life Sciences
The interaction between a host and its microbiome is an area of intense study. For the human host, it is known that the various body site-associated microbiomes impact heavily on health and disease states. For instance, the oral microbiome is a source of various pathogens and potential antibiotic resistance gene pools. The effect of historical changes to the human host and environment to the [...]
Automated tracking of avian parental care behavior
Published: 2023-11-16
Subjects: Behavior and Ethology, Biology, Life Sciences
1. Parental care may be an important source of phenotypic variation for ecological and evolutionary processes. However, it can be difficult to collect and interpret data on parental care behaviors. To address these challenges, we developed a new hardware and software platform for automated behavioral tracking called ABISSMAL (Automated Behavioral Tracking by Integrating Sensors that Survey [...]
Executive functions and brain morphology of male and female dominant and subordinate cichlid fish
Published: 2023-11-16
Subjects: Life Sciences
Living in a social dominance hierarchy presents different benefits and challenges for dominant and subordinate males and females, which might in turn affect their cognitive needs. Despite the extensive research on social dominance in group-living species, there is still a knowledge gap regarding how social status impacts brain development and cognitive abilities. Here, we tested male and female [...]
Sex-specific overdominance at the maturation vgll3 gene for reproductive fitness in wild Atlantic salmon
Published: 2023-11-15
Subjects: Life Sciences
Linking reproductive fitness with adaptive traits at the genomic level can shed light on the mechanisms that produce and maintain sex-specific selection. Here, we construct a multigenerational pedigree to investigate sex-specific selection on a maturation gene, vgll3, in a wild Atlantic salmon population. The vgll3 locus is responsible for ~40% of the variation in maturation (sea age at first [...]
Isotopic Evidence for Long-term Bioaccumulation of Perfluoroalkyl Substances (PFASs) in Icelandic seabirds
Published: 2023-11-15
Subjects: Life Sciences
Per- and polyfluoroalkyl substances (PFASs) are persistent anthropogenic pollutants with a widespread and significant impact on global marine ecosystems, particularly in the Arctic. Our study is centered in Iceland, an area where the merging of boreal and Arctic marine currents creates a complex ecological landscape. This setting is increasingly being influenced by the warming climate, adding [...]
Polyploid plants take cytonuclear perturbations in stride
Published: 2023-11-13
Subjects: Biology, Ecology and Evolutionary Biology, Genetics and Genomics, Life Sciences, Plant Biology
Hybridization in plants is often accompanied by nuclear genome doubling (allopolyploidy), which has been hypothesized to perturb interactions between nuclear and cytoplasmic (mitochondrial and plastid) genomes by creating imbalances in the relative copy number of these genomes and producing genetic incompatibilities between maternally derived cytoplasmic genomes and the half of the allopolyploid [...]
Extra-pair paternity variation in two passerine birds breeding in a gradient of urbanisation
Published: 2023-11-10
Subjects: Life Sciences
Urbanisation has been increasing worldwide in recent decades, driving environmental change and exerting novel selective pressures on wildlife. Phenotypic differences between urban and rural individuals have been widely documented in several taxa. However, the extent to which urbanisation impacts mating strategies is less known. Here, we inferred extra-pair paternity variation in nestbox-breeding [...]
Decomposing social environment effects on eco-evolutionary dynamics: from density regulation to frequency-dependent selection
Published: 2023-11-08
Subjects: Life Sciences, Social and Behavioral Sciences
The density and frequencies of interacting phenotypes create a type of environment which affects both phenotypic selection and population growth. Fluctuations in population density create temporal variation in population mean fitness, driving population dynamics, while fluctuations in phenotypic frequencies create variation in the relative fitness of phenotypes through frequency-dependent [...]
Refining the trophic diversity, ecological network structure, and bottom-up importance of prey groups for temperate reef fishes
Published: 2023-11-07
Subjects: Ecology and Evolutionary Biology, Integrative Biology, Life Sciences, Marine Biology
Marine fish communities are highly diverse, including all trophic levels of consumers and contributing to many ecosystem processes. Understanding the specific functional roles of many fish species and the importance of different prey groups for sustaining fish communities has, however, been limited by the historical classification of fishes into a few coarse trophic guilds. Using detailed diet [...]
Comparative life-history responses of lacewings to changes in temperature
Published: 2023-11-04
Subjects: Life Sciences
Insects play a crucial role in all ecosystems, and are increasingly exposed to higher in temperature extremes under climate change, which can have substantial effects on their abundances. However, the effects of temperature on changes in abundances or population fitness are filtered through differential responses of life-history components, such as survival, reproduction, and development, to [...]
Sharing the burden: Cabbage stem flea beetle pest pressure and crop damage are lower in rapeseed fields surrounded by other rapeseed crops
Published: 2023-11-04
Subjects: Agriculture, Entomology, Life Sciences, Other Ecology and Evolutionary Biology
The cabbage stem flea beetle (Psylliodes chrysocephala) is a significant pest of rapeseed (Brassica napus). Feeding by adult P. chrysocephala can cause severe leaf damage and larval infestation can reduce stem strength, both of which impact crop growth and development, causing substantial yield losses and economic damage. The structure of the agricultural landscape can regulate herbivorous pest [...]
Signatures of global processes shaping the structure of microbial co-occurrence networks
Published: 2023-11-01
Subjects: Ecology and Evolutionary Biology, Environmental Microbiology and Microbial Ecology Life Sciences, Life Sciences
Co-occurrence networks offer insights into the complexity of microbial interactions, particularly in highly diverse environments where direct observation is challenging. However, identifying the scale at which local and non-local processes structure co-occurrence networks remains challenging because it requires simultaneously analyzing network structure within and between local networks. In this [...]
The behavioural costs of overcrowding for gregarious cave-dwelling bats
Published: 2023-11-01
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
1. Bats are known for their gregarious social behaviour, often congregating in caves and underground habitats, where they play a pivotal role in providing various ecosystem services. Studying bat behaviour remains an underexplored aspect of bat ecology and conservation despite its ecological importance. 2. We explore the costs and impacts of overcrowding on bat social behaviour. This study [...]
