Linking inter-annual variation in environment, phenology, and abundance for a montane butterfly community (article)

This is the final version. Available from the Ecological Society of America via the DOI in this record. The dataset associated with this article is located in ORE at: https://doi.org/10.24378/exe.1963Climate change has caused widespread shifts in species’ phenology, but the consequences for population and community dynamics remain unclear because of uncertainty regarding the species-specific drivers of phenology and abundance, and the implications for synchrony among interacting species. Here, we develop a statistical model to quantify inter-annual variation in phenology and abundance over an environmental gradient, and use it to identify potential drivers of phenology and abundance in co-occurring species. We fit the model to counts of 10 butterfly species with single annual generations over a mountain elevation gradient, as an exemplar system in which temporally limited availability of biotic resources and favorable abiotic conditions impose narrow windows of seasonal activity. We estimate parameters describing changes in abundance, and the peak time and duration of the flight period, over ten years (2004–2013) and across twenty sample locations (930–2,050 m) in central Spain. We also use the model outputs to investigate relationships of phenology and abundance with temperature and rainfall. Annual shifts in phenology were remarkably consistent among species, typically showing earlier flight periods during years with warm conditions in March or May–June. In contrast, inter-annual variation in relative abundance was more variable among species, and generally less well associated with climatic conditions. Nevertheless, warmer temperatures in June were associated with increased relative population growth in three species, and five species had increased relative population growth in years with earlier flight periods. These results suggest that broadly coherent interspecific changes to phenology could help to maintain temporal synchrony in community dynamics under climate change, but that the relative composition of communities may vary due to interspecific inconsistency in population dynamic responses to climate change. However, it may still be possible to predict abundance change for species based on a robust understanding of relationships between their population dynamics and phenology, and the environmental drivers of both.Royal SocietyNatural Environment Research Counci

Risk equivalence as an alternative to balancing mean value when trading draft selections and players in major sporting leagues

In sports leagues that use an annual draft to assign eligible players to clubs, having a valueassociated with a draft selection can allow clubs to anticipate future growth of players and, ifa trading period exists, assist negotiations when exchanging draft selections and players.Typically, mean draft values often decline in either an exponential or geometric manner withincreasing draft selection number. Aggregate mean values have been used to comparetrade packages. However, clubs may also want to ensure that a trade does not increase theprobability of obtaining poor players in the draft. This paper therefore considers equivalenceof risk as an alternative trading strategy for club list managers. Here, risk is defined as theprobability of the aggregate value of the received draft selections being below a minimumacceptable level. For risk equivalence, a premium over and above mean market value mayneed to be provided when trading to secure higher draft selections

Photochemically re-bridging disulfide bonds and the discovery of a thiomaleimide mediated photodecarboxylation of C-terminal cysteines

Described in this work is a novel method for photochemically manipulating peptides and proteins via the installation of cysteine-selective photoactive tags. Thiomaleimides, generated simply by the addition of bromomaleimides to reduced disulfide bonds, undergo [2 + 2] photocycloadditions to reconnect the crosslink between the two cysteine residues. This methodology is demonstrated to enable photoactivation of a peptide by macrocyclisation, and reconnection of the heavy and light chains in an antibody fragment to form thiol stable conjugates. Finally we report on an intriguing thiomaleimide mediated photochemical decarboxylation of C-terminal cysteines, discovered during this study

Social acceptability of conservation interventions for flatback turtles: comparing expert and public perceptions

Sea turtles are facing significant threats, including anthropogenic warming, predation from feral animals, and sea level rise. While a range of intervention options are available, resource constraints and increasing time pressures means managers face the difficult task of prioritising options. To achieve successful conservation outcomes, managers are increasingly seeking to understand the social acceptability, as well as biological plausibility and economic feasibility, of these intervention options. Previous studies have used expert opinion as predictors of social acceptability, given their technical knowledge and experience implementing the interventions; however, the assumption that the social acceptability of interventions is the same for both the general public and experts is largely untested. We tested this assumption using surveys to assess the social acceptability of 24 interventions proposed for a population of flatback turtles Natator depressus in northwest Australia. Survey responses were collected from community members (residents) and experts (resource managers and researchers). Experts were asked to provide their own opinion of acceptability and how they perceived community members would rate intervention options. In general, residents ranked interventions that directly intervene with human behaviour or the environment as more acceptable than those that directly target turtles, while experts tended to favour direct turtle interventions. Experts incorrectly predicted that the community would not be influenced by the target of the intervention. Our findings highlight the importance of understanding social acceptability of interventions before implementation to inform management decisions and engagement and communication strategies, particularly when interventions might be controversial or restrict human behaviour directly

Finding common ground between UK based and Chinese approaches to earthen heritage conservation

Earthen heritage is one of the oldest and universal forms of heritage but its conservation poses many challenges. Establishing international collaborations could provide an efficient, sustainable mechanism to increase knowledge exchange, aiding the development of earthen heritage conservation strategies around the world. However, perceived differences in how Eastern and Western countries value earthen heritage and develop conservation strategies can pose challenges for establishing collaborations. To understand these perceived differences and whether they hinder collaborations, this paper compares British and Chinese heritage conservation policy and practice and then reports the results from an innovative workshop examining the approaches of 13 Chinese and 13 UK based heritage experts and researchers towards earthen heritage conservation. Workshop participants undertook bilingual discussions and completed a co-created questionnaire available in English and Mandarin. Both groups identified historic value as the most important value and maintenance of authenticity and integrity, need for scientific research and site scale conservation as vital considerations for conservation strategies. This study found that to understand the potential for collaboration, individual perspectives need consideration as well as policies and practices. This innovative bilingual, discussion-based approach has potential to aid collaborations for diverse international issues from wildlife conservation to cross-boundary pollution and climate chang
