“…The ontogeny of stress is still poorly understood but it is known that it may, for instance, shape pre‐migratory movements (Pakkala et al ., 2016) and to a further extent adult physiology, behaviour and fitness (Schoech, Rensel & Heiss, 2011; Crespi et al ., 2013). Additionally, CORT level differences between sexes in nestlings are rarely integrated into analyses (Tilgar, Saag & Moks, 2009; Wada et al ., 2009; Rensel, Wilcoxen & Schoech, 2010; Tilgar et al ., 2010; Kidawa et al ., 2014; Pakkala et al ., 2016; Newman et al ., 2017; Injaian, Taff & Patricelli, 2018; Injaian et al ., 2019; Bebus, Jones & Anderson, 2020; Expósito‐Granados et al ., 2020), or evidenced either no difference (Sockman & Schwabl, 2001; Beaugeard et al ., 2019; Grunst et al ., 2020) or low sex effects (Rensel, Wilcoxen & Schoech, 2011). This slight decrease in stress‐induced response in males may arise from habituation (i.e.…”

The last century has seen a steep decline in biodiversity, and anthropization is considered one of the major drivers of this decline. Anthropogenic disturbances, due to human presence and/or activities, may be perceived as chronic stressors by wildlife and potentially lead to deleterious effects on traits related to fitness. The main objective of the present study was to highlight the effects of these anthropogenic elements on wild birds on sparsely urbanized farmland, far less studied than in urbanized areas. We investigated during four successive breeding seasons whether the anthropization level, assessed by infrastructure density around nests, and the harvesting conditions around nests may impact physiological, behavioural and life‐history traits of Montagu's harrier Circus pygargus chicks. Higher anthropization levels were associated with higher basal corticosterone levels in nestlings during only one breeding season and a lower body condition at fledging for females, probably because they suffered from higher starvation than males. Nestlings reared in more anthropized areas or in harvested crops before their fledging harboured more fault bars on rectrices than those reared in less anthropized areas or in unharvested crops regardless of year and sex, which is suggestive of higher stress during development. Nestling behaviours were also impacted by anthropization level and harvesting conditions: chicks in harvested crops were more aggressive and in areas with higher anthropization levels more prone to escape than others. Because Montagu's harrier is a protected species, the impacts highlighted in the present study are a matter of concern, especially regarding farmland landscape modifications, and we advise limiting perturbations in areas where Montagu's harriers usually nest.

“…The formation of RNP complexes acts to regulate essential cellular functions from cell division to cell death, transcription to post-translational gene regulation, and downstream functions (Clayton and Shapira 2007;Glisovic et al 2008;Kishore et al 2010;Brinegar and Cooper 2016). It is important to note that the majority of these RNAs are regulated by cellular proteins, and the dysregulation of some of these RNAs has been implicated in diseases of the cardiovascular, neurological, and immune systems, as well as cancer (Lukong et al 2008;Esteller 2011;Brinegar and Cooper 2016;Conlon and Manley 2017;Newman et al 2017;Li et al 2018;Zhou et al 2019). Thus, the identification of RBPs and their modes of interaction could allow researchers to elucidate how fundamental cellular processes are governed.…”

RNA is involved in all domains of life, playing critical roles in a host of gene expression processes, host-defense mechanisms, cell proliferation, and diseases. A critical component in many of these events is the ability for RNA to interact with proteins. Over the past few decades, our understanding of such RNA–protein interactions and their importance has driven the search and development of new techniques for the identification of RNA-binding proteins. In determining which proteins bind to the RNA of interest, it is often useful to use the approach where the RNA molecule is the “bait” and allow it to capture proteins from a lysate or other relevant solution. Here, we review a collection of methods for modifying RNA to capture RNA-binding proteins. These include small-molecule modification, the addition of aptamers, DNA-anchoring, and nucleotide substitution. With each, we provide examples of their application, as well as highlight their advantages and potential challenges.
