Spatiotemporal dynamics and machine learning‐based prediction of above‐ground biomass in the Indus Delta mangroves

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Mangrove forests are important blue carbon ecosystems, yet long‐term above‐ground biomass (AGB) dynamics in arid deltaic systems remain poorly understood. Here, we integrated field‐derived AGB data with multisource remote sensing and machine learning models (random ...

Single Laboratory Validation of a Quantitative Core Shell-Based LC Separation for the Evaluation of Silymarin Variability and Associated Antioxidant Activity of Pakistani Ecotypes of Milk Thistle (Silybum Marianum L.)

open access: yesMolecules, 2018
Fruits of Silybum marianum (L.) Gaernt are the main source of taxifolin derived flavonolignans. Together, these molecules constitute a mixture called silymarin with many useful applications for cosmetic and pharmaceutic industries.

Global meta‐analysis reveals urban‐associated behavioural differences among wild populations

open access: yesJournal of Animal Ecology, EarlyView.
Urbanization drives rapid phenotypic change, yet broad patterns of behavioural responses remain unclear. Using a global phylogenetic meta‐analysis, we show urban populations exhibit increased boldness, aggression, exploration and activity—especially in birds—highlighting consistent behavioural shifts and revealing major taxonomic gaps that limit our ...

Effects of Biochar Amendment on CO2 Evolution in Four Ecotypes of Leyte Sab-A Basin Peatland, Philippines

open access: yesEnvironment and Natural Resources Journal
Atmospheric carbon cycle criticisms are significant liabilities in existing predictions of future climate. Carbon dioxide (CO2) discharges caused by climate warming through dense peat stores will frame a stable positive carbon cycle–atmospheric input. An

(Non)Parallel Evolution [PDF]

open access: yes, 2018
Parallel evolution across replicate populations has provided evolutionary biologists with iconic examples of adaptation. When multiple populations colonize seemingly similar habitats, they may evolve similar genes, traits, or functions.

Drought and growing season phenology over 35 years modulates species interactions among domestic and wild herbivores

open access: yesJournal of Animal Ecology, EarlyView.
Using a unique 35‐year dataset, this study shows that domestic livestock do not facilitate wild large herbivores as predicted by the grazing optimization hypothesis. Instead, competition caused avoidance of cattle by elk which intensified under drought, and highlights how climate change influences interactions among domestic and wild large herbivores ...

Effects of Vector Density on Blood Parasite Spread and Health Consequences for Avian Hosts: An Experimental Epidemiology Blueprint

open access: yesIntegrative Zoology, EarlyView.
In an experimental epidemiology setup, groups of pigeons were exposed to different numbers of infective malaria vectors. Vector number explained the speed of transmission, the final prevalence, and changes in host behavior. ABSTRACT Vector density plays a critical role in the transmission dynamics of vector‐borne diseases and thus in their health and ...

Quinoa crop biodiversity in Chile: an ancient plant cultivated with sustainable agricultural practices and producing grains of outstanding and diverse nutritional values [PDF]

open access: yes, 2011
Quinoa crop (Chenopodium quinoa) has been cultivated since the last seven thousand years in Latin America. However the nutritional and functional properties have been diffused only since the last decade.

Taxonomic resolution, ecotypes and the biogeography of Prochlorococcus

open access: yesEnvironmental Microbiology, 2009
Summary In order to expand our understanding of the diversity and biogeography of Prochlorococcus ribotypes, we PCR‐amplified, cloned and sequenced the 16S/23S rRNA ITS region from sites in the Atlantic and Pacific oceans.

Genomic Investigations Unveil the Genetic Underpinnings of Environmental Adaptation in African Goat Populations

open access: yesIntegrative Zoology, EarlyView.
This study integrates genomics and landscape genetics to analyze African goat environmental adaptation. Analyzing 1591 samples, it finds population structure differentiates geographically into four groups, with gene flow between wild Yura goats and North Africans.
