Distance sampling is widely used to estimate the abundance or density of wildlife populations. Methods to estimate wildlife mortality rates have developed largely independently from distance sampling, despite the conceptual similarities bet...

Phylogenetic diversity (PD) depends on sampling depth, which complicates the comparison of PD between samples of different depth. One approach to dealing with differing sample depth for a given diversity statistic is to rarefy, which means ...
Advances in multiplex PCR: balancing primer efficiencies and improving detection success [0.03%]
多重PCR研究进展：平衡引物效率及提高检测成功率

1. Multiplex PCR is a valuable tool in many biological studies but it is a multifaceted procedure that has to be planned and optimised thoroughly to achieve robust and meaningful results. In particular, primer concentrations have to be adju...
A simple method for in situ-labelling with 15N and 13C of grassland plant species by foliar brushing [0.03%]
一种通过叶片涂抹进行15N和13C草地植物原位标记的简单方法

1.Labelling plants with 15N and 13C stable isotopes usually require cultivation of plants in isotopically enriched soil and gas-tight labelling chambers - both approaches are not suitable if one aims to investigate in situ species interacti...
jPopGen Suite: population genetic analysis of DNA polymorphism from nucleotide sequences with errors [0.03%]

1. Next-generation sequencing (NGS) is being increasingly used in ecological and evolutionary studies. Though promising, NGS is known to be error-prone. Sequencing error can cause significant bias for population genetic analysis of a sequen...
A versatile telemetry system for continuous measurement of heart rate, body temperature and locomotor activity in free-ranging ruminants [0.03%]

1. Measuring physiological and behavioural parameters in free-ranging animals - and therefore under fully natural conditions - is of general biological concern but difficult to perform.2. We have developed a minimally invasive telemetry sys...

Nucleotide sequences sampled at different times (serially-sampled sequences) allow researchers to study the rate of evolutionary change and the demographic history of populations. Some phylogenies inferred from serially-sampled sequences ar...
A measure for describing and comparing post-reproductive lifespan as a population trait [0.03%]
一种描述和比较后生殖寿命的指标作为一种种群特征

1. While-classical life-history theory does not predict post-reproductive lifespan (PRLS), it has been detected in a great number of taxa, leading to the view that it is a broadly conserved trait, and attempts to reconcile theory with these...
