On the evolution of adult head structures and the phylogeny of Hydraenidae (Coleoptera, Staphyliniformia)
TLDR
The basal position of Orchymontiinae and Prosthetopinae suggests a Gondwanan origin of Hydraenidae and a primary preference for life in running water.

On the Head Morphology and Systematic Position of Helophorus (Coleoptera: Hydrophiloidea: Helophoridae)
External and internal features of the head of adults of Helophorus spp. were examined and described in detail. The 6 species under consideration show very little morphological variation. The only…

On the head morphology of Lepiceridae (Coleoptera: Myxophaga) and the systematic position of the family and suborder
TLDR
Adult head structures of Lepicerus inaequalis were examined in detail and interpreted functionally and phylogenetically, supporting a sistergroup relationship between both sub- orders.

Head structures of adults of Spercheus (Coleoptera: Spercheidae): their function and possible significance to Staphyliniform phylogeny
Cephalic anatomy of Sphaeriusidae and a morphology‐based phylogeny of the suborder Myxophaga (Coleoptera)
TLDR
The head of Sphaerius is less affected by size reduction compared with other beetles of the same size class and a fimbriate galea is lacking, and the observed features are evaluated in a cladistic analysis of larval and adult characters.

The adult head morphology of Dascillus (L.) (Dascilloidea: Dascillidae) and Glaresis Erichson (Scarabaeoidea: Glaresidae) and its phylogenetic implications
External and internal structures of the adult head of Glaresis sp. and Dascillus cervinus are described in detail and compared with conditions found in other polyphagan representatives such as…
The phylogeny of Coleopterida (Hexapoda) – morphological characters and molecular phylogenies
TLDR
A large morphological dataset comprising external and internal features of adults and immature stages is presented here and analysed phylogenetically, indicating that a complex feeding apparatus suitable for saprophagy and sporophagy was ancestral in Coleoptera, with secondary reduction in Archostemata and Adephaga.

The head morphology of Clambidae and its implications for the phylogeny of Scirtoidea (Coleoptera: Polyphaga)
TLDR
The results tentatively support the monophyly of Scirtoidea and a close relationship between Clambidae and Eucinetidae is suggested by one shared derived feature of the mandible, a long and slender apical tooth with a serrate edge.

Aves y plantas leñosas en cortinas rompevientos en León, Nicaragua
The abundance and diversity of birds and woody plants was compared in windbreaks in 'good condition' (5 rows of trees, dense understory), 'degraded' windbreaks (2-3 rows of trees, sparse understory)…
