orchaRd 2.0: An R package for visualizing meta-analyses with orchard plots

Shinichi Nakagawa, Malgorzata Lagisz, Rose E O'Dea, et al.

Published: 2023-01-07
Subjects: Life Sciences

1. Although meta-analysis has become an essential tool in ecology and evolution, reporting of meta-analytic results can still be much improved. To aid this, we have introduced the orchard plot, which presents not only overall estimates and their confidence intervals but also shows corresponding heterogeneity (as prediction intervals) and individual effect sizes. 2. Here, we have added [...]

Sarah Weber Hertel, Jana Stupavsky, Kristine Alford, et al.

Published: 2023-01-03
Subjects: Animal Sciences, Biology, Environmental Studies, Life Sciences, Social and Behavioral Sciences

Surveys assessing attitudes and values about the environment can help predict human behavior towards wildlife and develop effective conservation goals alongside local communities. Southern Alabama is a hotspot for biodiversity and endemism in the United States and is in need of studies to protect its wildlife. Land and wildlife management practices in Alabama have moved from indigenous-led [...]

Humans have inundated the environment worldwide with antimicrobials for about one century, giving selective advantage to antibiotic-resistant bacteria. Therefore, antibiotic resistance has become a public health problem responsible for increased mortality, and extended hospital stays because the efficacy of antibiotics has diminished. Hospitals and other clinical settings have implemented [...]

ForageFeeder: a low-cost open source feeder for randomly distributing food

Maggie Zhang, Andrew Kyle Schulz, Josh Meyerchick, et al.

Subjects: Animal Experimentation and Research, Life Sciences, Research Methods in Life Sciences

Automated feeders have long fed mice, livestock, and poultry, but are incapable of feeding zoo animals such as gorillas. Gorilla food, consisting of cut vegetables and fruits, is too large to be dispensed by automated feeders. Instead gorillas are manually at a set time and location, which decreases the exercise and enrichment that accompanies their natural foraging. We designed and built [...]

Like little lagoons: the contribution of valli da pesca to the Ecosystem Services supply of the Venice Lagoon

Alice Stocco, Laura Basconi, Silvia Rova, et al.

The Venice lagoon social-ecological system is characterized by a strong relationship between the natural environment and human activities. This is especially noticeable in the aquaculture and hunting reserves of the lagoon, locally known as valli da pesca. Previous works about Ecosystem Services (ESs) in the Venice lagoon focused on the so-called “open lagoon”, overlooking the role of the valli [...]

Use of Airborne Laser Scanning to assess effects of understorey vegetation structure on nest-site selection and breeding performance in an Australian passerine bird

In wild bird populations, the structure of vegetation around nest-sites can influence the risk of predation of dependent offspring, generating selection for nest-sites with vegetation characteristics associated with lower predation rates. However, vegetation structure can be difficult to quantify objectively in the field, which might explain why there remains a general lack of understanding of [...]

How do monomorphic bacteria evolve? The Mycobacterium tuberculosis complex and the awkward population genetics of extreme clonality

Christoph Stritt, Sebastien Gagneux

Subjects: Evolution, Genetics and Genomics, Genomics, Life Sciences, Molecular Genetics, Pathogenic Microbiology, Population Biology

Exchange of genetic material through sexual reproduction or horizontal gene transfer is ubiquitous in nature. Among the few outliers that rarely recombine and mainly evolve by de novo mutation are a group of deadly bacterial pathogens, including the causative agents of leprosy, plague, typhoid, and tuberculosis. The interplay of evolutionary processes is poorly understood in these organisms. [...]

Evaluating top-down, bottom-up, and environmental drivers of pelagic food web dynamics along an estuarine gradient

Tanya L Rogers, Samuel M Bashevkin, Christina E Burdi, et al.

Published: 2022-12-15
Subjects: Aquaculture and Fisheries Life Sciences, Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology

Identification of the key biotic and abiotic drivers within food webs is important for understanding species abundance changes in ecosystems, particularly across ecotones where there may be strong variation in interaction strengths. Using structural equation models and four decades of integrated data from the San Francisco Estuary, we investigated the relative effects of top-down, bottom-up, and [...]

An Annotated Checklist of Lichens of the Opal Creek Wilderness and Adjacent Areas: a Pre-Fire Baseline

John Villella, Lalita Calabria, Bruce McCune, et al.

Published: 2022-12-15
Subjects: Life Sciences

In 2020 the Beachie Creek Fire burned a large area of forest in the northern Oregon Cascade Range including public and private land and much of the Opal Creek Wilderness. We compiled a baseline data set from various sources of the lichens known to occur before the fire within this area. These data are presented as an annotated species checklist documenting two hundred and eighty species. Euopsis [...]

Habitat destruction threatens jaguars in a mixed land use region of eastern Bolivia

René Meißner, Moritz Blumer, Merlin Weiß, et al.

Published: 2022-12-14
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Zoology

Large carnivores such as the jaguar (Panthera onca) are particularly susceptible to population decline and local extinction as a result of habitat loss. Here, we report on the long-term monitoring of a local jaguar population in a mixed land use area in the eastern lowlands of Bolivia from March 2017 to December 2019. We recorded 15 jaguar individuals and four reproduction events (five offspring [...]

Exploratory personality is independent of telomere dynamics in a wild bird population

Tara Cox, Thomas J Brown, Alexandra M Sparks, et al.

Published: 2022-12-14
Subjects: Life Sciences

Numerous studies have demonstrated that individuals within a species will consistently vary between one another in behavioural traits. A prominent adaptive explanation for such ‘animal personalities’ relates to an individual’s intrinsic state driving and/or being driven by behaviour. Telomeres – the protective caps at the end of chromosomes which exist in most organisms – have been proposed as a [...]

Advances in the reconstruction of the Spider Tree of Life: a roadmap for spider systematics and comparative studies

In the last decade and a half, advances in genetic sequencing technologies have revolutionized systematics, transforming the field as studying morphological characters; a few genetic markers have given way to genomic data sets in the phylogenomic era. A plethora of molecular phylogenetic studies on many taxonomic groups have come about, converging on, or refuting prevailing morphology or [...]

A framework for improving the reproducibility of data extraction for meta-analysis

Published: 2022-12-14
Subjects: Ecology and Evolutionary Biology, Life Sciences, Psychology, Research Methods in Life Sciences

Extracting data from studies is the norm in meta-analyses, enabling researchers to generate effect sizes when raw data are otherwise not available. While there has been a general push for increased reproducibility in meta-analysis, the transparency and reproducibility of the data extraction phase is still lagging behind. Unfortunately, there is little guidance of how to make this process more [...]

How could noise affect aquatic ecosystems? A lack of zooplankton studies.

Loïc Prosnier

Published: 2022-12-13
Subjects: Life Sciences

There is a growing interest in the effects of noise pollution on aquatic ecosystems. To date, these works mainly focus on hearing species, especially fish and mammals. Species from lower trophic level, including many invertebrate species, are less studied despite their ecological importance. Within these taxa, studies investigating the effects of noise on holozooplankton are very rare. For the [...]

Co-crediting system for carbon and biodiversity

Leho Tedersoo, Jaan Sepping, Alexey S Morgunov, et al.

Published: 2022-12-13
Subjects: Life Sciences

Carbon crediting and land offsets for biodiversity protection are implemented to tackle the challenges of increasing greenhouse gas emissions and loss of global biodiversity, but these two mechanisms are not optimal when considered separately. Focusing solely on carbon capture – the primary goal of most carbon-focused offsetting commitments – often results in the establishment of non-native, [...]
