Carabid beetles (Coleoptera: Carabidae) are considered as one of the most cardinal invertebrate predatory groups in many ecosystems, including forests. Previous studies revealed that the predation pressure provided by carabids significantly regulates the ecological network of invertebrates. Nevertheless, there is no direct estimation of the predati...

Although the functional trait approach can facilitate the understanding of mechanisms that underline community responses to habitat alteration, only a few studies used this way on exploring the structure of insect assemblages compared to taxon‐based analyses. We compared the descriptive power of medium‐term effects (2014‐2018) of forestry treatment...

Moving from one habitat to another, the dispersal of individuals has consequences for their conditions, population dynamics and gene flow. Our major motivation was to explore the effects of different forestry treatments, such as preparation (partial) cuts and clear cuts, on the selected population of the forest ground beetle, Carabus coriaceus (Col...

Movement trajectories are usually recorded as a sequence of discrete movement events described by two parameters: step length (distance) and turning angle (bearing). One of the most widespread methods to record the geocoordinates of each step is by a GPS device. Such devices have limited suitability for recording fine movements of species with low...

Activity density is one of the most common measures in ground-dwelling arthropods, including carabids. It is based on individuals' activity and population density, yet there is no available evidence whether the individual movement can be a good proxy for activity density. Therefore, in our study, we aimed to explore this link in two large ground be...

Correction to: Biologia https://doi.org/10.1007/s11756-021-00805-x The original version of the article was published as first online in Biologia on 18 June 2021. Unfortunately, the original version of this article contains a mistake in the Material and Methods section (Page 3, lines 19–22 in the first section) in terms of body/tag mass ratio for in...

Agricultural intensification may act as an environmental filter shaping invertebrate assemblages at multiple spatial scales. However, it is not fully understood which scale is the most influential. Therefore, we utilized a hierarchical approach to examine the effect of local management (inorganic fertilization and soil properties; within-field scal...

Female-only colour polymorphism is rare in birds, but occurs in brood parasitic cuckoos (Cuculidae). Obligate brood parasites leave incubation and parental care to other species (hosts), so female-female interactions can play a role in how parasites guard critical resources (host nests) within their laying areas. The plumage of adult female common...

Agricultural intensification is one of the major drivers of biotic homogenization and has multiple levels ranging from within-field management intensity to landscape-scale simplification. The enhancement of invertebrate assemblages by establishing new, semi-natural habitats, such as set-aside fields can improve biological pest control in adjacent c...

In gravel pits, a mosaic of habitats with various environmental conditions created during mining has a great potential for persistence of many species. We focused on such a mosaic in a gravel pit surrounded by agricultural landscape. We investigated which habitats within sludge deposits in different successional stages (from bare sands to secondary...

Carabus hungaricus is an endangered habitat specialist of tall-grass steppe occurring in the Pannonian region. In this study, we used radio telemetry to examine whether habitat type (different habitat patches in steppe mosaic), sex, time of day, temperature and air pressure affect the activity of this species. During the reproductive period of C. h...

1. Perching dragonflies are closely associated with the physical structure of vegetation because adults utilise plants when foraging, thermoregulating, and mate-seeking. However, little attention has been given to which structural attribute of vegetation is playing a key role within foraging habitat use. 2. This study focused on the influence of d...

Some carabid species are not restricted to a single habitat only, but use various types of habitats. In these species, relatively little is known about the utilization of occupied habitats and factors affecting their movement within these habitats. In this study, we focus on the movement activity of ubiquitous Carabus ullrichii during its reproduct...

In the few last decades, nature it the Czech Republic has been fighting a sharp decline in biological diversity caused by huge range of drivers. Landscape fragmentation, urbanization or abandoning less productive plots are among the most important ones. At the same time, the Czech Republic’s landscape has becoming homogenous. Therefore, particularl...

It is not so long ago that the use of radiotelemetry for studying animal biology and ecology was only applicable to vertebrates. However, recently developed radio transmitters are smaller and lighter, which opens up new opportunities for using this method to track insects in natural conditions. As an example, we present our study on the movement ac...

Radio telemetry is an advanced method for studying movement behaviour which is one of the keys to understanding species ecology and biology. Using this method we studied the movement of Carabus ullrichii Germar, 1824, alarge and apterous ground beetle species. Four individuals (one male, three females) were equipped with 0.28 g transmittersand radi...
