1. Descriptions of Pupae of the Darkling Beetle Subfamily Phrenapatinae (Coleoptera: Tenebrionidae)

Author:
Bouchard, Patrice

Annales zoologici 2019 v.69 no.1 pp. 173-189
ISSN:
0003-4541
Subject:
Tenebrionidae; adults; comparative study; pupae; redescriptions; taxonomic keys
Abstract:
... Relationships of darkling beetles in the subfamily Phrenapatinae (Coleoptera: Tenebrionidae) are poorly known. Meaningful comparative studies are hampered by the fact that morphological structures of adults typically used for assessing relationships within Tenebrionidae cannot be used successfully in this group because they are either absent or extremely reduced. The pupal stage of twelve species ...

Bryophyta; boreal forests; canopy; climate change; climatic factors; cold; community structure; coniferous forests; dead wood; ecological resilience; forest management; latitude; microhabitats; species richness; temperature; trees; Quebec
Abstract:
... The capacity of individual species to tolerate environmental changes is a major driver of ecosystem resilience. This subject has been a hot topic in boreal forests due to the greater effect of climate change anticipated at northern latitudes. However, to date it has been mainly examined for trees, with comparatively little emphasis on other species groups. In this study, bryophytes were sampled in ...

Subject:
monitoring; particle size; particle size distribution; process control
Abstract:
... Particle size control in mineral processing is typically achieved using an index characterising the whole distribution, e.g. the sieve opening through which a given mass fraction of the population would pass. Although mineral liberation is the goal of size reduction, its use for monitoring and process control applications is not reported because its online measuring is currently not possible. This ...

Abstract:
... Understanding the importance of dead wood-associated biodiversity and related ecological functions has become increasingly important in forest ecosystem management. Yet, studies on dead wood diversity frequently focus on conspicuous organisms such as birds or saproxylic beetles, and are rarely deployed across significant climatic gradients. Here, we investigated the potential role of deadwood as a ...

Abstract:
... Enhanced coagulation can be an effective way to reduce disinfection by-product (DBP) precursor concentrations. Where turbidity is not extremely high, the natural organic matter concentration evaluated by total or dissolved organic carbon concentration or UV absorbance is known to be the most important factor for determining the adequate coagulant dose. Yet, treatment plant operators are often face ...

As the method does not require homogenization of tissues prior to their incubation in the denaturant, specimen collected in the field can be immediately transferred to the urea-LiCl solution. The method was also tested on tissues of other cnidarian species. RNA was isolated from fresh tissues o ...
