Data from: All is fish that comes to the net: metabarcoding for rapid fisheries catch assessment

AbstractMonitoring marine resource exploitation is a key activity in fisheries science and biodiversity conservation. Since research surveys are time-consuming and costly, fishery-dependent data (i.e. derived directly from fishing vessels) are increasingly credited with a key role in expanding the reach of ocean monitoring. Fishing vessels may be seen as widely ranging data-collecting platforms, which could act as a fleet of sentinels for monitoring marine life, in particular exploited stocks. Here, we investigate the possibility of...

Using incidental mark-encounter data to improve survival estimation

Seth Harju, Scott Cambrin, Roy Averill-Murray, Melia Nafus, Kimberleigh Field & Linda Allison
1. Obtaining robust survival estimates is critical, but sample size limitations often result in imprecise estimates or the failure to obtain estimates for population subgroups. Concurrently, data are often recorded on incidental re-encounters of marked individuals, but these incidental data are often unused in survival analyses. 2. We evaluated the utility of supplementing a traditional survival dataset with incidental data on marked individuals that were collected ad-hoc. We used a continuous time-to-event exponential survival model...

Wildwatch Kenya expert verified data

Scientists are increasingly using volunteer efforts of citizen scientists to classify images captured by motion-activated trail-cameras. The rising popularity of citizen science reflects its potential to engage the public in conservation science and accelerate processing of the large volume of images generated by trail-cameras. While image classification accuracy by citizen scientists can vary across species, the influence of other factors on accuracy are poorly understood. Inaccuracy diminishes the value of citizen science derived data and...

Data from: Climate change and landscape-use patterns influence recent past distribution of giant pandas

Junfeng Tang, Ronald R. Swaisgood, Megan A. Owen, Xuzhe Zhao, Fuwen Wei, Nicholas W. Pilfold, Xuyu Yang, Xiaodong Gu, Zhisong Yang, Qiang Dai, Mingsheng Hong, Hong Zhou, Jindong Zhang, Shibin Yuan, Han Han & Zejun Zhang
Climate change is one of the most pervasive threats to biodiversity globally, yet the influence of climate relative to other drivers of species depletion and range contraction remain difficult to disentangle. Here, we examine climatic and non-climatic correlates of giant panda (Ailuropoda melanoleuca) distribution using a large-scale 30-year dataset to evaluate whether a changing climate has already influenced panda distribution. We document several climatic patterns, including increasing temperatures, and alterations to seasonal temperature and precipitation....

Heterozygosity–fitness correlations reveal inbreeding depression in neonatal body size in a critically endangered rock iguana

Jeanette B. Moss, Glenn P. Gerber & Mark E. Welch
Inbreeding depression, though challenging to identify in nature, may play an important role in regulating the dynamics of small and isolated populations. Conversely, greater expression of genetic load can enhance opportunities for natural selection. Conditional expression concentrates these opportunities for selection and may lead to failure of detection. This study investigates the possibility for age-dependent expression of inbreeding depression in a critically endangered population of rock iguanas, Cyclura nubila caymanensis. We employ heterozygote-fitness correlations to...

Context-dependent effects of relative temperature extremes on bill morphology in a songbird

Katie LaBarbera, Kyle J. Marsh, Kia R. R. Hayes & Talisin T. Hammond
Species increasingly face environmental extremes. While responses of morphological traits to changes in average environmental conditions are well-documented, responses to environmental extremes remain poorly understood. Bird bills contribute to thermoregulation, with considerable heat loss possible through the bill surface, and with bill morphology shaped by long-term thermal conditions. We used museum specimens to investigate the relationship of bill surface area (SA) in dark-eyed juncos Junco hyemalis to traditional measures of climate (temperature and precipitation) and...
