We studied behavioural traits and behavioural correlations in larvae of a univoltine damselfly, Lestes sponsa, along its latitudinal distribution, spreading over 3300 km. We compared behavioural profiles among larvae grown either in native temperatures and photoperiods or averaged constant temperatures and photoperiods. We expected latitudinal differences in behavioural traits regardless of the conditions in which larvae were grown, with northern populations expressing higher activity, boldness and foraging efficiency. When grown in native conditions, northern larvae...
Domestication has greatly changed the social and reproductive behavior of dogs relative to that of wild members of the genus Canis, which typically exhibit social monogamy and extended parental care. Unlike a typical grey wolf pack that consists of a single breeding pair and their offspring from multiple seasons, a group of free-ranging dogs (FRDs) can include multiple breeding individuals of both sexes. To understand the consequences of this shift in reproductive behavior, we reconstructed...
Plant herbivore interactions: Combined effect of ground water level, root vole grazing and sedge silicificationZbigniew Borowski, Karol Zub, Marcin Sulwiński, Małgorzata Suska-Malawska & Marek Konarzewski
1. Accumulation of silica (Si) by plants can driven by (1) herbivore pressure (and therefore, plant-herbivore interactions) (2) geo-hydrological cycles or (3) a combination of (1) and (2), with (1-3) possibly affecting Si concentration with a 1-year delay. 2. To identify the relative significance of (1-3) we analysed the concentration of Si in fibrous tussock sedge (Carex appropinquata), the population density of the root vole (Microtus oeconomus) and the ground water level, over 11 years....
Copepods of the genus Calanus are the key components of zooplankton. Understanding their response to a changing climate is crucial to predict the functioning of future warmer high-latitude ecosystems. Although specific Calanus species are morphologically very similar, they have different life strategies and roles in ecosystems. In this study, C. finmarchicus and C. glacialis were thoroughly studied with regard to their plasticity in morphology and ecology both in their preferred original water mass (Atlantic vs....
Data and codes to replicate the analysis in: The spatial ecology of conflicts: Unravelling patterns of wildlife damage at multiple scalesCarlos Bautista, Eloy Revilla, Teresa Berezowska-Cnota, Néstor Fernández, Javier Naves & Nuria Selva
Human encroachment into natural habitats is typically followed by conflicts derived from wildlife damages to agriculture and livestock. Spatial risk modelling is a useful tool to gain understanding of wildlife damage and mitigate conflicts. Although resource selection is a hierarchical process operating at multiple scales, risk models usually fail to address more than one scale, which can result in the misidentification of the underlying processes. Here, we addressed the multi-scale nature of wildlife damage occurrence...
Lagomorpha is a clade of herbivorous mammals nested within Euarchontoglires, one of the major placental groups represented today. It comprises two extant families with markedly different body plans: the long-eared and long-limbed Leporidae (hares and rabbits) and the short-eared and short-limbed Ochotonidae (pikas). These two lagomorph lineages diverged probably during the latest Eocene/early Oligocene, but it is unclear whether the last common ancestor of crown lagomorphs was more leporid- or more ochotonid-like in morphology. Palaeolagus,...
Simple and reliable measurement of insulin sensitivity may be important for the prevention of insulin-resistance related diseases. Surrogate indices of insulin sensitivity are of limited utility in population without signs of metabolic syndrome. The aim of our study was to provide simple and accurate index of insulin sensitivity. The study group comprised 150 young healthy participants. Hyperinsulinemic-euglycemic clamp was performed. Regression models with different laboratory parameters were constructed. Validation cohort 1 comprised independent group of...
Brood sex ratio, early chick survival, and cell-mediated immunity measurements for 3 experimental groups of Larus canus and Chroicocephalus ridibundus pairsDariusz Bukaciński, Monika Bukacińska & Przemysław Chylarecki
Sex allocation theory predicts that parents should adjust their brood sex ratio to maximize fitness returns in relation to parental investment. Adaptive adjustment of sex ratio may be driven by differential costs of rearing sons and daughters or differential benefits of investing limited resources into offspring of different sex. In both cases, possible sex ratio bias should depend on parental condition. For sexually dimorphic birds with males larger than females, sons may be less likely...
Small mammals impact plant recruitment globally via size-dependent seed predation, generating a unimodal pattern across ecosystems. Chen et al. (2021) critiqued our seed removal analysis, advocating corrections for exposure time. We show in our rebuttal that such manipulations are unwarranted and argue for increased emphasis on plant recruitment metrics. This archive holds the updated seed removal dataset used for our rebuttal.
Anatomy of the nasal and auditory regions of the fossil lagomorph Palaeolagus haydeni: systematic and evolutionary implicationsŁucja Fostowicz-Frelik, Irina Ruf & Jin Meng
Palaeolagus, a late Eocene to early Miocene North American lagomorph genus, represented by numerous and well-preserved specimens, has been long considered a basal leporid, although it is currently understood as a stem lagomorph. Based on micro-computed tomography (μCT) data and 3D reconstructions, here we present the first description of intracranial structures of the nasal and auditory regions of a complete skull of Palaeolagus haydeni from the early Oligocene of Nebraska. Although Palaeolagus haydeni shows a...
