Simapse – simulation maps for ecological niche modelling

Methods in Ecology and Evolution, 2012
Summary1. Artificial neural networks (ANNs) are known for their powerful predictive power in the analysis of both linear and nonlinear relationships. They have been successfully applied to several fields including ecological modelling and predictive species’ distributions.2.

Bifidobacterium Pseudolongum‐Derived Acetate Attenuates Acute Pancreatitis Through GPR43‐Mediated Suppression of M1 Macrophage Polarization

Advanced Science, EarlyView.
The severity of acute pancreatitis (AP) is linked to reduced abundance of Bifidobacterium pseudolongum (B. pseudolongum). Administration of B. pseudolongum or its key metabolite acetate alleviates pancreatic and systemic inflammation by suppressing M1 macrophage polarization.

Updated geographical distribution of the Sunbittern(Eurypyga helias: Eurypigidae)

Caldasia, 2022
The Sunbittern (Eurypyga helias), despite having a wide distribution, is poorly studied and with few records in its area of distribution. Updating the distributions of species allows us to understand distri-butional patterns which are useful in ecology ...

Which Factors Determine Spatial Segregation in the South American Opossums (Didelphis aurita and D. albiventris)? An Ecological Niche Modelling and Geometric Morphometrics Approach [PDF]

, 2016
Didelphis albiventris and D. aurita are Neotropical marsupials that share a unique evolutionary history and both are largely distributed throughout South America, being primarily allopatric throughout their ranges.

Multi‐Enzyme Mimetic Molybdenum Nitride Nanozymes Reshape Subgingival Microenvironment for Synergistic Periodontitis Therapy via ROS Regulation and Microbiome Remodeling

Advanced Science, EarlyView.
ABSTRACT Periodontitis, a chronic inflammatory disease initiated and sustained by plaque microorganisms and host immune response, remains an intractable oral disease and a leading cause of tooth loss worldwide. Traditional mechanical debridement and adjunctive antibiotic or antiseptic therapy often shows limited efficacy due to the complex anatomical ...

Ecological theory as a foundation to control pathogenic invasion in aquaculture [PDF]

, 2014
Detrimental host-pathogen interactions are a normal phenomenon in aquaculture animal production, and have been counteracted by prophylactic use of antibiotics. Especially, the youngest life stages of cultivated aquatic animals are susceptible to pathogen

Gut Lactate Boosts Ruminococcus via Histone Lactylation to Mediate Time‐Restricted Feeding Protection in Crohn's Disease

Advanced Science, EarlyView.
TRF enriches Ruminococcus, a bacterial genus producing SCFAs, and activates the epithelial HIF‐1α signaling pathway. This mechanism protects the colonic mucosa from inflammatory insults in colitis models. Mechanistically, gut lactate production during starvation and refeeding mediates H4K12la, which increases SLC9A3 expression and creates an acidic gut

Spatial prediction of species’ distributions from occurrence-only records: combining point pattern analysis, ENFA and regression-kriging [PDF]

, 2009
A computational framework to map species’ distributions (realized density) using occurrence-only data and environmental predictors is presented and illustrated using a textbook example and two case studies: distribution of root vole (Microtes oeconomus ...

Ecological niche modelling

Current Biology
One of the central research questions in ecology and biogeography revolves around understanding the spatial distribution patterns of organisms, the factors influencing species abundance, and why in certain areas there are more species or individuals than in others.

Diversity of Pharmaceuticals Enhances Antibiotic Resistance in the Invertebrate Gut via Biofilm‐Mediated Mechanisms

Advanced Science, EarlyView.
Pharmaceutical diversity acts as an independent driver of antibiotic resistance in soil invertebrates. While bulk soil remains unaffected, the collembolan gut microbiome exhibits significant resistance gene enrichment under complex chemical exposure and diurnal warming.
