Subjects: Ecology and Evolutionary Biology, Life Sciences, Marine Biology, Other Ecology and Evolutionary Biology

Microbes are essential to the holobiome of all organisms, so when organisms are impacted by environmental stressors the changes to microbial communities can inform on the health state of the host and even cause host disease. In early 2019 marine heatwaves occurred across eastern Australia, resulting in differential bleaching across Lord Howe Island reefs. Here we examined the Symbiodiniaceae and [...]

Behavioural and trophic variation within a well-established invasive round goby population

Nicholas Patrick Moran, Jane Windfeldt Behrens

Published: 2023-11-20
Subjects: Life Sciences

An animal’s behavioural traits can influence the outcomes of ecological interactions within their food-web, including what they eat, their vulnerability to predation and who they compete with. Despite this, few studies have directly measured links between among-individual behavioural and trophic variation. Invasive species like the round goby (Neogobius melanostomus) are often found to have [...]

Rare, but potentially impactful, extreme events in socio-ecological systems (SES) can trigger significant consequences. The scarcity of theoretical frameworks for such events in SES is due to data limitations and difficulty in building coupled SES models. We explore the effect of extreme events on coupled socio-ecological systems using two stylized case studies: harvesting of old-growth forests [...]

The Pangolin Universal Notching System (PUNS): A Foundational Scale Marking Methodology for Pangolins

Jeannie Jo-Miller Martin, Jacqueline Y Buckley, Ellen Connelly, et al.

Subjects: Ecology and Evolutionary Biology, Zoology

Abstract Due to significant anthropogenic pressures, all eight established species of pangolin are listed on Appendix I of the Convention on International Trade in Endangered Species of Wild Fauna and Flora, the highest level of international protection possible. Pangolin population status assessments are incomplete, particularly in areas with high exploitation and limited field assets. [...]

Breeding History of Three Mega Rice (Oryza sativa L.) Varieties (BR11, BRRI dhan28, BRRI dhan29) of Bangladesh – A Review

Arpan Das

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 However, outdated rice cultivars and poor cultivar replacement have led to a decline in rice productivity in Bangladesh.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

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

Gwyn Dahlquist-Axe, Francesca Standeven, Camilla Speller, et al.

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

Grace Smith-Vidaurre, Tania Molina, Erich D. Jarvis, et al.

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

Angelo Guadagno, Zegni Triki

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 [...]

ATLANTIC SPATIAL: a dataset of landscape, topographic, hydrologic and anthropogenic metrics for the Atlantic Forest

Maurício Humberto Vancine, Bernardo Brandão Niebuhr, Renata L. Muylaert, et al.

Published: 2023-11-16
Subjects: Spatial Science, Terrestrial and Aquatic Ecology

Space is one of the main drivers of biodiversity, once it regulates the underlying processes affecting the distribution and dynamics of species. It is a fundamental factor in face of the rapid climate and land use and land cover changes at local and global scales, which are linked to habitat loss and fragmentation and their impacts on various organisms. The Atlantic Forest of South America (AF) [...]

Forecasting insect dynamics in a changing world

Christie A Bahlai

Published: 2023-11-15
Subjects: Ecology and Evolutionary Biology, Entomology

Predicting how insects will respond to stressors through time is difficult because of the diversity of insects, environments, and approaches used to monitor and model. Forecasting models take correlative/statistical, mechanistic models, and integrated forms; in some cases, temporal processes can be inferred from spatial models. Because of heterogeneity associated with broad community [...]

Sex-specific overdominance at the maturation vgll3 gene for reproductive fitness in wild Atlantic salmon

Kenyon Brice Mobley, Henry J. Barton, Mikko Ellmén, et al.

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 [...]

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 [...]

The Evolutionary Puzzle of Human Twinship

Augusto Dalla Ragione, Cody Ross, Daniel Redhead

Published: 2023-11-15
Subjects: Biological and Physical Anthropology, Evolution, Maternal and Child Health, Population Biology, Social and Cultural Anthropology

Natural selection should favor litter sizes that optimize trade-offs between brood-size and offspring viability. Across the primate order, modal litter size is one, suggesting a deep history of selection favoring minimal litters. Humans, however---despite having the longest juvenile period and slowest life-history of all primates---still produce twin-births at appreciable rates, even though such [...]
