Diet results from Adelie penguins at Bechervaise Island and Whitney Point, 2012/13

These spreadsheets provide the proportions of prey DNA sequences in the scats of Adelie penguins at Bechervaise Island and Whitney Point in East Antarctica.

Samples were collected during two stages of the breeding season: mid brood guard (Bechervaise Island-January 4-6th 2013, Whitney Point 23- 28th December 2012) and mid creche (23-26th January 2013). Scat samples were collected from breeding birds, chicks and non-breeders at Bechervaise Island and breeding birds and chicks at Whitney Point. 'Breeders' were identified as individuals brooding or provisioning a chick, whereas 'non-breeders' were usually pairs that had reoccupied the colony and were building new practice nests with no chick present. Non-breeders in the colony include immature birds that have not yet bred and mature birds of breeding age that did not breed in a particular season (e.g. no partner or insufficient body condition)

DNA from each sample was extracted and sequenced as per the protocols in the following paper:
Jarman, S.N., McInnes, J.C., Faux, C., Polanowski, A.M., Marthick, J., Deagle, B.E., Southwell, C. and Emmerson, L. 2013 Adelie penguin population diet monitoring by analysis of food DNA in scats. PLoS One 8, e82227. (doi:10.1371/journal.pone.0082227).

The Raw Data spreadsheet contains the proportion of each prey group of each individual sample, plus the total sequence count of prey items. Only samples with greater than 100 prey sequences are included in the dataset. The summary datasheet contains only prey taxa which contained greater than 2% of the proportion of sequences.

Analysis of these data have been published in: McInnes JC, Emmerson L, Southwell C, Faux C, Jarman SN. (2016) Simultaneous DNA-based diet analysis of breeding, non-breeding and chick Adelie Penguins http://dx.doi.org/10.1098/rsos.150443 Quality: 2018-09-24 - The original datasheet was reformatted to fit OBIS/GBFI/IPT Biodiversity.AQ standardS. The new datasheet 'AdeliePenguinDiet2012_2013.csv" provides datasetID, recordNumber, resourceID, relatedResourceID, relationshipOfResource, relationshipAccordingTo, eventRemarks, eventDate, year, month, day, locality, locationID, verbatimLatitude, verbatimLongitude, decimalLatitude, decimalLongitude, continent, countryCode, preparation, identificationQualifier, occurrenceStatus, organismQuantity, organismQuantityType, basisOfRecord, behaviour, and institutionCode. The lowest taxonomical rank of the species identified that could be determined is provided, after matched in WoRMS (World Register of Marine Species).

本数据集附带的电子表格记录了南极东部贝切韦兹岛（Bechervaise Island）与惠特尼角（Whitney Point）的阿德利企鹅（Adelie penguin）粪便样本中猎物DNA序列的占比情况。

样本采集于繁殖季的两个阶段：育雏守卫中期（贝切韦兹岛：2013年1月4日至6日；惠特尼角：2012年12月23日至28日）与幼雏聚群中期（2013年1月23日至26日）。

贝切韦兹岛的粪便样本采集自繁殖成鸟、雏鸟及非繁殖个体；惠特尼角的样本则采集自繁殖成鸟与雏鸟。其中，"繁殖个体"指正在孵卵或育雏投喂的个体，"非繁殖个体"通常指已重返繁殖群落、正在搭建新的练习巢且无雏鸟的繁殖对。群落内的非繁殖个体包括尚未参与繁殖的亚成鸟，以及在特定繁殖季未参与繁殖的适龄成鸟（例如无配偶或身体条件未达繁殖要求）。

所有样本的DNA均按照以下文献中的实验流程提取并测序：Jarman, S.N.、McInnes, J.C.、Faux, C.、Polanowski, A.M.、Marthick, J.、Deagle, B.E.、Southwell, C.与Emmerson, L. 2013年发表于PLoS One的《通过粪便食物DNA分析监测阿德利企鹅种群食谱》，卷8，文章编号e82227，DOI:10.1371/journal.pone.0082227。

原始数据电子表格包含每个个体样本的各猎物类群占比，以及猎物序列总计数。本数据集仅纳入猎物序列数大于100的样本。汇总数据表仅收录序列占比大于2%的猎物类群。

基于本数据集的分析成果已发表于：McInnes JC、Emmerson L、Southwell C、Faux C、Jarman SN 2016年的《繁殖、非繁殖个体与雏鸟阿德利企鹅的同步DNA食谱分析》，链接：http://dx.doi.org/10.1098/rsos.150443。

数据质量说明（2018年9月24日）：原始数据表已重新格式化，以符合OBIS（Ocean Biogeographic Information System）、GBFI、IPT（Integrated Publishing Toolkit）的Biodiversity.AQ标准。新数据表`AdeliePenguinDiet2012_2013.csv`包含以下字段：datasetID、recordNumber、resourceID、relatedResourceID、relationshipOfResource、relationshipAccordingTo、eventRemarks、eventDate、year、month、day、locality、locationID、verbatimLatitude、verbatimLongitude、decimalLatitude、decimalLongitude、continent、countryCode、preparation、identificationQualifier、occurrenceStatus、organismQuantity、organismQuantityType、basisOfRecord、behaviour与institutionCode。所有经WoRMS（World Register of Marine Species，世界海洋物种登记册）匹配的物种，均会给出可确定的最低分类阶元。
