Crushing and Cutting: Shape Variation and Morphological Integration Between the Claws of Two Swimming Crab Species (Brachyura: Portunidae)

open access: yesActa Zoologica, EarlyView.
ABSTRACT This study investigated shape variations and morphological integration between the components of crusher and cutter claws in two species of swimming crabs, Callinectes danae and Callinectes ornatus. The propodi and dactyli of the claws were analysed in males and females of both species, using geometric morphometric techniques to identify ...

Revealing patterns of endemism in the transatlantic family Chelodesmidae (Polydesmida: Diplopoda)

open access: yesCladistics, EarlyView.
Abstract With fossil records dating back to the Silurian/Late Ordovician, millipedes stand out as one of the earliest terrestrial animal groups. Their limited vagility and high endemism make them valuable tools for formulating and testing biogeographic hypotheses, including those related to macro‐vicariance events.

Remarkable harvestmen from the Czech Republic [PDF]

open access: yes, 2013
The fauna of harvestmen of the Czech Republic is relatively well-known (SILHAVY 1956, MARTENS 1978). Still, species new for the country have recently been found both in natural (KLlMES & BEZDECKA 1995) and synanthropic habitats (KLlMES 1995).

Orchard Management Influences Predation of Halyomorpha halys Eggs

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We investigated predation of eggs of the invasive stink bug Halyomorpha halys on apple trees in conventional, organic, and extensively managed Dutch orchards. Predation exceeded 40% in extensively managed orchards but was only about 10% in conventional and organic ones. We used camera traps to reveal natural enemies that may contribute to H.

Egaenus convexus - eine neue Weberknechtart aus der Tschechischen Republik [PDF]

open access: yes, 2013
The harvestmen fauna of the Czech Republic is relatively species-poor; so far 29 species have been found, of them 23 in Bohemia, the western part of the country, and 26 species in Moravia, the eastern part of the Czech ...

Macroecology of parental care in arthropods: higher mortality risk leads to higher benefits of offspring protection in tropical climates [PDF]

open access: yes, 2016
The intensity of biotic interactions varies around the world, in such a way that mortality risk imposed by natural enemies is usually higher in the tropics.

Height and phytotelm size affect the invertebrate communities of epiphytic bromeliads in the Amazon rainforest

open access: yesEcological Entomology, EarlyView.
The height at which epiphytic bromeliads are found affects the invertebrate community composition within them. The size of epiphytic bromeliads is positively correlated with species richness of both aquatic and terrestrial invertebrates. Whether bromeliads were found in primary or secondary forest did not have a significant effect on the community of ...

Carinostoma elegans new to the Slovakian harvestmen fauna (Opiliones, Dyspnoi, Nemastomatidae)

open access: yesArachnologische Mitteilungen, 2014
A new genus and species of small harvestman was found for the first time in Slovakia – Carinostoma elegans (Sørensen, 1894). One male and two females were collected in the Mlyňany arboretum of the Slovak Academy of Science (western Slovakia ...

Glacial Legacies—How Refugial Dynamics Shaped the Evolution of the Alpine Endemic Bush‐Cricket Anonconotus italoaustriacus

open access: yesMolecular Ecology, Volume 35, Issue 3, February 2026.
ABSTRACT Mountain ranges like the European Alps harbour large endemic biodiversity shaped by Pleistocene climatic oscillations. The flightless bush‐cricket Anonconotus italoaustriacus, endemic to the Southern Limestone Alps (SLA) and the eastern Central Alps (CA), provides an ideal model to study the evolutionary and refugial dynamics of endemic alpine

Abundanz und Vikarianz epigäischer Weberknechtarten (Arachnida: Opiliones) in einem Auwaldgebiet des Mainzer Beckens

open access: yesArachnologische Mitteilungen, 2005
From the beginning of November 2003 to January 2004 the opilionid fauna was collected in a floodplain forest of the Rhine valley west of Mainz. Altogether 1643 individuals were captured in pitfall traps; these belong to six species representing three ...
