Pathogens and the infectious diseases that they cause can have devastating impacts on host individuals and populations. To better understand how pathogens are able to cause disease, we can investigate the genetic mechanisms underlying the infection process. Hosts may respond to infection by upregulating defence pathways. Pathogens, in turn, evade these host immune responses as they infect and cause disease. As this process unfolds and each organism responds to the other, gene expression changes in both the host and the pathogen. These gene expression changes can be captured by dual RNA‐seq, which simultaneously captures the gene expression profiles of a host and of a pathogen during infection.

Scientists from international conservation charity ZSL (Zoological Society of London), Imperial College London and conservationists from the Rotokare Scenic Reserve Trust used acoustic monitoring devices to listen in on the ‘conversations’ of New Zealand’s endemic hihi bird, allowing them to assess the success of the reintroduction without impacting the group.
For the first time ZSL scientists were able to use the calls of a species as a proxy for their movement. A happy hihi call sounds like two marbles clanging together in what is known as the ‘stitch’ call. Scientists saw the calls change from an initial random distribution to a more settled home range – marking the hihi reintroduction and the new method a success.

It’s already been a busy 2019 for the six BES journal blogs. We’ve covered topics from leaving the nest to sustainable food production, stress in academia to climate change. On Relational Thinking we learned that cats can’t trespass. And Animal Ecology in Focus taught us that some crabs steal food from plants.
Today we’re having a look back at some of last month’s highlights from across the blogs:
Cats Can’t Trespass
This post was created by the author of one of our published papers. It’s a really creative and funny illustrated summary of their paper.
Analysis of datasets collected on marked individuals has spurred the development of statistical methodology to account for imperfect detection. This has relevance beyond the dynamics of marked populations. A couple of great examples of this are determining site occupancy or disease infection state.
EURING Meetings
The regular series of EURING-sponsored meetings (which began in 1986) have been key to this development. They’ve brought together biological practitioners, applied modellers and theoretical statisticians to encourage an exchange of ideas, data and methods.
Sometimes stress can be anticipated, avoided or mitigated. Other times, it sneaks up on you and sucker punches you in the face. A quick google search turns up loads of articles and op-eds on the topic – this, this and this are just three of the first examples I found. Stats abound on the negative effect it can have on students, staff and productivity. Mental health problems and stress in academia are increasingly recognised, but knowing about an issue and solving it are very different things.
My lab at the University of Manchester is fairly big and busy. Headed by the current BES president, and with over 30 people, and many millions of pounds in funding, it can be a stressful place. I am by no means an expert in stress, but I can tell you about my personal experiences and some of the ways that the University of Manchester helps staff and students deal with stress here.

Scientists at the University of Southampton have developed maps of chemicals found in jellyfish which could offer a new tool for conservation in British waters and fisheries. The maps will also be able to detect fraudulently labelled food in retail outlets by helping to trace the origins of seafood.
It is widely accepted that many conservation challenges are directly related to human behaviour. Whether it is the over-collection of a rare orchid by harvesters in Southeast Asia, or the decisions by collectors in Europe to buy and smuggle these orchids home, understanding the extent and nature of these behaviours is essential to addressing the threats they might cause. This has led conservation researchers and practitioners to start looking outside of their discipline, to find methods and approaches from across the social sciences to improve our understanding of these complex issues.
While this interdisciplinarity is a positive move for conservation, it is important that we treat these ‘new’ methods carefully and understand their limitations. If we don’t, there is a risk that our new toolbox full of exciting methods that sound great on a funding application, may in fact not be making what we do any better, or in extreme cases they may even be making it worse.
Muitos desafios em conservação estão diretamente relacionados com o comportamento humano. Quer seja a recolha excessiva de uma orquídea rara no Sudeste Asiático, ou a compra e contrabando dessas orquídeas por colecionadores na Europa, entender a magnitude e a natureza desses comportamentos é essencial para lidar com as ameaças que eles podem causar. Isso levou os investigadores e profissionais da área de conservação a começarem a olhar para fora da sua própria disciplina, de modo a encontrar métodos e abordagens das ciências sociais para melhorar a nossa compreensão sobre estas questões complexas.
Embora esta interdisciplinaridade seja um passo positivo para a conservação, é importante tratar esses “novos” métodos com cuidado e entender as suas limitações. Se não o fizermos, existe o risco da nossa nova caixa de ferramentas, repleta de métodos interessantes que soam bem em candidaturas a financiamento, na verdade não melhorar aquilo que nós geralmente já fazemos ou, em casos extremos, até piorá-lo.
Tendo isto em conta, um grupo de cientistas sociais em conservação, liderado por investigadores das Universidades de Oxford e Exeter, decidiu examinar em profundidade um desses “novos” métodos, fornecer recomendações sobre quando e como ele deveria ser usado, e quando não deveria. O artigo, disponível gratuitamente na revista científica Methods in Ecology and Evolution nesta semana, examina a Técnica de Contagem de Itens (TCI), que tem sido cada vez mais usada em conservação para fazer perguntas sobre tópicos “sensíveis”. Continue reading “Limitações e benefícios da técnica de contagem de itens: considerações sobre o uso de novos métodos em Conservação”
Today, we are pleased to announce the latest new member of the Methods in Ecology and Evolution Associate Editor Board. Laura Graham joins us from the University of Southampton, UK as an Applications Editor. You can find out a little more about her below.
Laura Graham
“I’m a quantitative ecologist interested in how anthropogenic changes such as climate change and habitat loss affect global ecosystems, and how this in turn affects human well-being. I develop computational methods for spatial ecology to facilitate the reproducible analysis of social-ecological systems and ecosystem services. I’m interested in using novel statistical methods and heterogeneous sources of data to answer applied and theoretical questions.” Continue reading “New Associate Editor: Laura Graham”
This post presents our reflections from two sessions at the first British Ecological Society Annual Meeting since the Palaeoecology Special Interest Group (SIG) was formed. Did the term “palaeoecology” make you want to stop reading? Then you’re not alone – our field of ecology seems to have drifted apart from neoecology over the last couple decades. We seem to have been separated by our choice of methods, rather than brought together by the fascinating, complex and essential challenges of better understanding ecosystem function that we share.
The diversity of talks at BES 2018 showed that ecologists working on time scales beyond the scope of direct study are researching the same urgent, exciting questions as other flavours of ecology. And that they are doing it by using an ever-growing range of methods and technologies. The Thematic Session ‘Advancing Our Understanding of Long-Term Ecology’ showcased advances in studies of long-term ecology. The Palaeoecology Oral Session demonstrated the diversity within this field. We don’t have room to mention all presenters, so we’d like to highlight contributions from two speakers in each session which demonstrate how strong the shared ground between palaeoecology and neoecology is.
