1. The biology of Megalolaelaps colossus (Acari: Dermanyssina)

Author:
Cómbita-Heredia, Orlando; Quintero-Gutiérrez, Edwin Javier; Romero-García, Nicole; Klompen, Hans

Abstract:
... Aspects of life history and host interactions of Megalolaelaps colossus were studied in a laboratory environment. These mites appear to require a host for survival, but hosts do not survive very long in a laboratory setting, leading to a modified rearing protocol relying on regular host replacement. Specific data on phenology and incidence are reported. Direct observations on feeding, mating, tran ...

Abstract:
... With approximately 3000 marine species, Tunicata represents the most disparate subtaxon of Chordata. Molecular phylogenetic studies support Tunicata as sister taxon to Craniota, rendering it pivotal to understanding craniate evolution. Although successively more molecular data have become available to resolve internal tunicate phylogenetic relationships, phenotypic data have not been utilized cons ...

Abstract:
... Clonality is a largely underexplored plant life-history trait with possibly profound effects on plant demography. Clonal growth constitutes an alternative reproductive pathway, which should provide clonal species with an advantage over non-clonal ones under disturbance regimes unfavourable to regeneration from seeds.We investigated how clonal and non-clonal species differ in their life histories ( ...

Abstract:
... Clonality and sexual reproduction are important drivers of spatial genetic structure (SGS) in seagrass meadows. However, few genetic studies have focused on the annual or short-lived perennial seagrass Zostera japonica, which has been declining dramatically along coastal regions of China. In this study, we assessed the effects of asexual and sexual reproduction on the dispersal of Z. japonica usin ...

Abstract:
... Multicellular animals and plants represent independent evolutionary experiments with complex multicellular bodyplans. Differences in their life history, a mobile versus sessile lifestyle, and predominant embryonic versus postembryonic development, have led to the evolution of highly different body plans. However, also many intriguing parallels exist. Extension of the vertebrate body axis and its s ...

Abstract:
... Complex haploid‐diploid life cycles amongst marine organisms may be maintained by ecological differences in life‐history phases. For red algal species within the Gigartinaceae, such differences may be driven, in part, by different cell wall composition and resultant biomechanical strengths of haploid and diploid phases. A field experiment tested the attachment strengths of gametophytes and tetrasp ...

Most research has focused on FFD whereas LFD, FD and second flowering events were neglected although they are crucial events. To assess whether flowering patterns change species-specifically with changing abiotic conditions and whether these are re ...

Abstract:
... Many freshwater ecosystems are becoming saltier and/or warmer, but our understanding of how these factors interact and affect the physiology and life history outcomes of most aquatic species remain unknown. We hypothesize that temperature modulates ion transport rates. Since ion transport is energetically expensive, increases in salinity and/or temperature may influence ion flux rates and ultimate ...

Across the Kapala Clade, various conspicuous morphological modifications – notably the long mesoscutellar spines – have led to the description of numerous genera. Monophyly of the clade has been supported in mo ...

Abstract:
... Phenotypic plasticity is a central topic in ecology and evolution. Individuals may differ in the degree of plasticity (individual‐by‐environment interaction (I × E)), which has implications for the capacity of populations to respond to selection. Random regression models (RRMs) are a popular tool to study I × E in behavioural or life‐history traits, yet evidence for I × E is mixed, differing betwe ...

Since larvae of many species complete devel ...

Here, we wanted to explore to what extent genetic constraints and correlational selection can explain patterns of covariation between dispersal and key life‐history traits—lifespan and reproduction. A prediction from the fitness‐associated dispersal hypothesis was that lower genetic quality is assoc ...
