... Reproductive success is associated with age in many taxa, increasing in early life followed by reproductive senescence. In socially monogamous but genetically polygamous species, this generates the interesting possibility of differential trajectories of within‐pair and extra‐pair siring success with age in males. We investigate these relationships simultaneously using within‐individual analyses wi ...
... The inoculation of plants with plant-growth-promoting rhizobacterium has been an effective strategy for enhancing plant salt tolerance to diminish the loss of agricultural productivity caused by salt stress; however, the signal transmitted from bacteria to the plant under salt stress is poorly understood. In this study, the salt tolerance of Arabidopsis thaliana and Zea mays was enhanced by inocul ...
... While typically insectivorous, large centipedes are known to attack and eat vertebrates. Though opportunistic, this behavior might be relatively frequent. Predation of centipedes on snakes is rarely observed. We report an incident, witnessed at the Sakaerat Biosphere Reserve, Thailand, involving the predation of a scolopendrid centipede, Scolopendra dawydoffi, on a female colubrid snake, Sibynophi ...
... BACKGROUND: The present study aimed to evaluate the nutritional status of patients undergoing haemodialysis (HD) by comparing nutritional risk scores with biochemical, anthropometric and body composition variables. METHODS: Eighty‐five individuals [65.9% male, mean (SD) age 62 (14) years] participated in a cross‐sectional study. Global Objective Assessment (GOA) and Modified Global Subjective Asse ...
behavior change; health behavior; lifestyle; obesity; weight loss
Abstract:
... Despite the significance placed on lifestyle interventions for obesity management, most weight loss is followed by weight regain. Psychological concepts of habitual behaviour and automaticity have been suggested as plausible explanations for this overwhelming lack of long‐term weight loss success. Interventions that focus on changing an individual's behaviour are not usually successful at changing ...
... Aspergillus flavus, an opportunistic pathogen, contaminates maize and other key crops with carcinogenic aflatoxins (AFs). Besides AFs, A. flavus makes many more secondary metabolites (SMs) whose toxicity in insects or vertebrates has been studied. However, the role of SMs in the invasion of plant hosts by A. flavus remains to be investigated. Cyclopiazonic acid (CPA), a neurotoxic SM made by A. fl ...
... Ribosomal protein S6 (RPS6) is an indispensable plant protein regulated, in part, by ribosomal protein S6 kinase (S6K) which, in turn, is a key regulator of plant responses to stresses and developmental cues. Increased expression of RPS6 was detected in Nicotiana benthamiana during infection by diverse plant viruses. Silencing of the RPS6 and S6K genes in N. benthamiana affected accumulation of Cu ...
... The evolution of multicellularity is one of the key transitions in evolution and requires extreme levels of cooperation between cells. However, even when cells are genetically identical, noncooperative cheating mutants can arise that cause a breakdown in cooperation. How then, do multicellular organisms maintain cooperation between cells? A number of mechanisms that increase relatedness amongst co ...
... BACKGROUND: Cardiovascular disorders remain the leading cause of death in type 2 diabetic patients. In the present study, a systematic review and a meta‐analysis of randomised controlled trials (RCTs) were conducted aiming to evaluate the effect of magnesium supplementation on type 2 diabetes (T2D) associated cardiovascular risk factors in both diabetic and nondiabetic individuals. METHODS: PubMed ...
... BACKGROUND: The Nutrition Education for Management of Osteodystrophy trial showed that stage‐based nutrition education by dedicated dietitians surpasses existing practices in Lebanon with respect to lowering serum phosphorus among general haemodialysis patients. The present study explores the effect of nutrition education specifically on hyperphosphataemic patients from this trial. METHODS: Hyperp ...
Eciton; ant colonies; foraging; insect behavior; trail pheromones
Abstract:
... We describe an emigration of the Neotropical army ant Eciton mexicanum where the head of the emigration column was separated in time from previous raid column activity, and the emigration was not connected to the new bivouac site by a column of workers. Over 12 h elapsed between raid activity and the onset of emigration, suggesting the emigration followed a long-lasting pheromone trail. We suggest ...

Abstract:
... BACKGROUND: Evidence exists for an association between accordance with a Mediterranean diet pattern and slower rates of cognitive decline. However, an ‘Americanised’ version of the Mediterranean diet screener is needed to assess accordance in the USA. Thus, the Mediterranean Eating Pattern for Americans (MEPA) tool was developed to assess accordance with a Mediterranean‐like food pattern when time ...
... BACKGROUND: Dietary modification is critical in the self‐management of chronic kidney disease. The present study describes the accuracy, quality and health literacy demand of renal diet information for adults with kidney disease obtained from the Internet and YouTube (www.youtube.com). METHODS: A comprehensive content analysis was undertaken in April and July 2015 of 254 eligible websites and 161 ...
... We present evidence that populations of an invasive plant species that have become re‐associated with a specialist herbivore in the exotic range through biological control have rapidly evolved increased antiherbivore defences compared to populations not exposed to biocontrol. We grew half‐sib families of the invasive plant Lythrum salicaria sourced from 17 populations near Ottawa, Canada, that dif ...

Abstract:
... Originating in a 1983 Mexican Government Program, the term ‘food sovereignty’ was coined in 1996 by La Via Campesina—a global peasant network—to address concerns within the civil society for food security. Rather than to accept the neoliberal framework of mainstream food security definition and governance, the food sovereignty movement seeks to view food security as the right of peoples to define ...
... Antigenic diversity in pathogenic microbes can be a result of at least three different processes: diversifying selection by acquired immunity, host–pathogen coevolution and/or host specialization. Here, we investigate whether host specialization drives diversity at ospC (which encodes an immunodominant surface protein) in the tick‐transmitted bacterium Borrelia afzelii. We determined prevalence an ...

Abstract:
... In this article we describe a movement to regenerate and sustainably use native grasslands using innovative grazing and cropping strategies. We find that this movement has the essential characteristics of a “community of practice” (COP) and is a strong example of a bottom-up transition toward a sustainable agroecological farming system. This COP was identified and described using participatory rur ...
... Male courtship behavior and displays influence female mating decisions, and therefore affect mating success in a diverse range of organisms. While there is substantial evidence confirming that females prefer males who invest more in courtship, less attention has been paid to the relative importance of individual behaviors, and the discrete sequences of courtship that result in mating success. The ...

Abstract:
... Increases in wildfire frequency and extent in rangelands pose a growing threat to private property and ecosystem health. The state of Idaho, USA, recently promoted rangeland fire protection associations (RFPAs)—nonprofit organizations of local citizens who contribute to firefighting efforts on public rangelands—as one way to mitigate rangeland wildfire risk. This study used in-depth interviews wit ...

Abstract:
... In recent years, animal welfare has become an important element of sustainable production that has evolved along with the transformation of animal production systems. Consumer attitudes towards farm animal welfare are changing around the world, especially at emerging markets of Asia, Africa and Latin America. Survey-based research on consumer attitudes towards farm animal welfare has increased. Ho ...
