Incorporating fine-scale environmental heterogeneity into broad-extent models [0.03%]
将细尺度环境异质性纳入大范围模型中

Laura J Graham et al.
A key aim of ecology is to understand the drivers of ecological patterns, so that we can accurately predict the effects of global environmental change. However, in many cases, predictors are measured at a finer resolution than the ecologica...
Classifying ecosystems with metaproperties from terrestrial laser scanner data [0.03%]
基于激光雷达数据的生态系统分类研究
Ian Paynter,Daniel Genest,Edward Saenz et al.
Ian Paynter et al.
In this study, we introduce metaproperty analysis of terrestrial laser scanner (TLS) data, and demonstrate its application through several ecological classification problems. Metaproperty analysis considers pulse level and spatial metrics d...
Field testing a novel high residence positioning system for monitoring the fine-scale movements of aquatic organisms [0.03%]

Matthew M Guzzo et al.
Acoustic telemetry is an important tool for studying the behaviour of aquatic organisms in the wild.VEMCO high residence (HR) tags and receivers are a recent introduction in the field of acoustic telemetry and can be paired with existing al...
Field methods for sampling tree height for tropical forest biomass estimation [0.03%]
热带森林生物量估计中树木高度抽样调查的方法学研究
Martin J P Sullivan,Simon L Lewis,Wannes Hubau et al.
Martin J P Sullivan et al.
Quantifying the relationship between tree diameter and height is a key component of efforts to estimate biomass and carbon stocks in tropical forests. Although substantial site-to-site variation in height-diameter allometries has been docum...
How to use (and not to use) movement-based indices for quantifying foraging behaviour [0.03%]
如何使用(和不使用)基于运动的指标来量化觅食行为

Movement-based indices such as moves per minute (MPM) and proportion time moving (PTM) are common methodologies to quantify foraging behaviour. We explore fundamental drawbacks of these indices that question the ways scientists have been us...

The investigation of genetic clusters in natural populations is an ubiquitous problem in a range of fields relying on the analysis of genetic data, such as molecular ecology, conservation biology and microbiology. Typically, genetic cluster...
TreeSimGM: Simulating phylogenetic trees under general Bellman-Harris models with lineage-specific shifts of speciation and extinction in R [0.03%]
树模拟gm：在r中，在谱系特异性的分化和灭绝转变下的一般贝尔曼-哈里斯模型下的系统发育树模拟

Understanding macroevolutionary processes using phylogenetic trees is a challenging and complex process that draws on mathematics, computer science and biology. Given the development of complex mathematical models and the growing computatio...
Analysis of nectar from low-volume flowers: A comparison of collection methods for free amino acids [0.03%]
低花蜜量花朵花蜜中游离氨基酸提取方法的比较与分析研究论文
Eileen F Power,Daniel Stabler,Anne M Borland et al.
Eileen F Power et al.
Floral nectar is a reward offered by flowering plants to visiting pollinators. Nectar chemistry is important for understanding plant nutrient allocation and plant-pollinator interactions. However, many plant species are difficult to sample ...

Meta-analyses conventionally weight study estimates on the inverse of their error variance, in order to maximize precision. Unbiased variability in the estimates of these study-level error variances increases with the inverse of study-level...
An efficient extension of N-mixture models for multi-species abundance estimation [0.03%]
一种有效的N-混合模型多物种丰度估计扩展方法
Juan Pablo Gomez,Scott K Robinson,Jason K Blackburn et al.
Juan Pablo Gomez et al.
In this study we propose an extension of the N-mixture family of models that targets an improvement of the statistical properties of rare species abundance estimators when sample sizes are low, yet typical for tropical studies. The proposed...
