Developmental constraints in cave beetles.
In insects, whilst variations in life cycles are common, the basic patterns typical for particular groups remain generally conserved. One of the more extreme modifications is found in some subterranean beetles of the tribe Leptodirini, in which the number of larval instars is reduced from the ancestral three to two and ultimately one, which is not active and does not feed. We analysed all avail...
متن کاملLife-history specialization was not an evolutionary dead-end in Pyrenean cave beetles.
Research on subterranean organisms has focused on the colonization process and some of the associated phenotypic changes, but little is known on the long-term evolutionary dynamics of subterranean lineages and the origin of some highly specialized complex characters. One of the most extreme modifications is the reduction of the number of larval instars in some Leptodirini beetles from the ances...
متن کاملAphid secondary symbionts do not affect prey attractiveness to two species of predatory lady beetles
Heritable symbionts have been found to mediate interactions between host species and their natural enemies in a variety of organisms. Aphids, their facultative symbionts, and their potential fitness effects have been particularly well-studied. For example, the aphid facultative symbiont Regiella can protect its host from infection from a fungal pathogen, and aphids with Hamiltonella are less li...
متن کاملRegression of the Time-Keeping Ability in Carabid Beetles by Phylogenetic Adaptation to Cave Conditions
Locomotor activity patterns of six cavernicolous carabid species representing the course of regressive evolution have been investigated under constant conditions. The analysis establishes new relationships between the circadian structure of the activity patterns observed under constant conditions (LL and D D ) and the phylogenetic adaptation to cave conditions. This is due to the mathematical m...
متن کاملA new genus and species for the first recorded cave-dwelling Cavernicola (Platyhelminthes) from South America
Species diversity of Brazilian cave fauna has been seriously underestimated. A karst area located in Felipe Guerra, northeastern Brazil, which is a hotspot of subterranean diversity in Brazil, has revealed more than 20 troglobitic species, most of them still undescribed. Based on recent samplings in this karst area, we document the occurrence of the suborder Cavernicola (Platyhelminthes) in Sou...
