Researchers are commonly in a situation, often after an experiment, where they want to compare the central tendency of some measure across number groups. If groups is simply 2, then there little controversy as appropriate analysis, with normally t-test or nonparametric equivalent being adopted. greater than most elementary statistical textbooks suggest performing analysis variance (ANOVA) test null hypothesis that all same and, if this rejected, implementing post hoc testing identify which...
Relationships between temperature and preoviposition, preeclosion, premolt developmental periods for the tick Ixodes scapularis Say were investigated by holding field-collected ticks in laboratory at temperatures of 0 to 32°C constant daylength. The duration these decreased significantly with increasing temperature. Host origin, prior storage 4°C, season collection also associated variations preoviposition period. For each stage, effect on development rate was best described as a power...
Vigilance has been predicted to decrease with group size due increased predator detection and dilution of predation risk in larger groups. Although earlier literature reviews have provided ample support for this prediction, an increasing number studies failed document a decline vigilance size. In addition, prediction based thus far on the P value relationship between rather than quantitative assessment effect magnitude. Here, I use meta-analysis empirical relationships birds published last...
Three main benefits are thought to underlie communal roosting in birds: a reduction thermoregulation demands, decrease predation risk, and an increase foraging efficiency. I investigated interspecific variation tendencies across categories of several ecological factors examine the relevance each functional hypothesis evolutionary transition secondary reversal solitary habits. The study phylogenetic tree included 30 families 437 species. Evolutionary transitions occurred more often on...
Measured foraging strategies often cluster around values that maximize the ratio of energy gained over spent while (efficiency), rather than would long-term net rate gain (rate). The reasons for this are not understood. This paper focuses on time and constraints to illustrate relationship between efficiency rate-maximizing develops models provide a simple framework analyze in two distinct contexts. We assume capturing ingesting food their own use (which we term feeding), foragers behave so...
The classic literature on predation dealt almost exclusively with solitary predators and their prey. Going back to Lotka-Volterra optimal foraging theory, the theory about predation, including predator-prey population dynamics, was developed for species. Various consequences of sociality have been considered only recently. Similarly, while it long recognized that prey species can benefit from living in groups, research adaptive value mostly emerged 1970s. main theme this book is various ways...
Poor research reporting is a major contributing factor to low study reproducibility, financial and animal waste. The ARRIVE (Animal Research: Reporting of In Vivo Experiments) guidelines were developed improve quality many journals support these guidelines. influence this unknown. We hypothesized that papers published in supporting the would show improved compared with those non-supporting journals. retrospective, observational cohort study, from 5 (SUPP) 2 (nonSUPP) journals, before (2009)...
ABSTRACT A description of the relationship between mean food intake rate (MFIR) and group size is important in assessing adaptiveness living animals. Several hypotheses argue that foraging groups can be beneficial terms MFIR but an overall assessment evidence available thus far was lacking. I examined this birds using studies provided a measure different sizes evaluated effect study design type. In addition, noted some mechanisms thought to responsible for changes with quantified impact...
Passive surveillance for the occurrence of tick Ixodes scapularis Say (1821) and their infection with Lyme borreliosis spirochaetes Borrelia burgdorferi s.l. has taken place in Canada since early 1990. Ticks have been submitted from members public, veterinarians, medical practitioners to provincial, federal, university laboratories identification, data collated B. detected at National Microbiology Laboratory. The locations collection 2,319 I. were mapped, we investigated potential risk...
Adaptive hypotheses for the evolution of flocking in birds have usually focused on predation avoidance or foraging enhancement. It still remains unclear to what extent each factor has contributed flocking. If were sole involved, should not be prevalent when is relaxed. I examined tendencies along with mean and maximum flock size species living islands where risk either absent negligible then compared these results matched counterparts mainland. The dataset consisted 46 pairs from 22...
Abstract Introduction The aim of this prospective, randomized, controlled, double-blind study was to evaluate the effects tiludronate (TLN), a bisphosphonate, on structural, biochemical and molecular changes function in an experimental dog model osteoarthritis (OA). Methods Baseline values were established week preceding surgical transection right cranial/anterior cruciate ligament, with eight dogs serving as OA placebo controls others receiving four TLN injections (2 mg/kg subcutaneously)...
Recent studies suggest that airway smooth muscle remodeling is an early event in the course of asthma. Little known effects long-term antigen avoidance and inhaled corticosteroids on chronically established remodeling. We sought to measure peripheral airways horses with heaves, a naturally occurring asthma-like disease. Heaves-affected adult ongoing inflammation bronchoconstriction were treated fluticasone propionate (with without concurrent avoidance) (n = 6) or alone 5). Lung function...
Most developmental studies on suicide do not take into account individual variations in trajectories.Using a life course approach, this study explores models of trajectories.Two hundred and fourteen suicides were assessed with mixed methods. Statistical analysis using combined discrete-time survival (DTS) growth mixture modelling (GMM) generated various trajectories, path (Mplus) identified exogenous mediating variables associated these groups share common risk factors, independently major...
