Dung Beetle (Scarabaeinae) Diversity Of The Highest Elevation In West Africa: The Nimba Mountain Range, Jacob Bowen
Dung Beetle (Scarabaeinae) Diversity Of The Highest Elevation In West Africa: The Nimba Mountain Range, Jacob Bowen
Mahurin Honors College Capstone Experience/Thesis Projects
The Nimba Mountain Range in Guinea, Ivory Coast, and Liberia is within the Upper Guinean Forests, a critical biodiversity hotspot highly threatened by various human activities. The region is home to many endemic species including the viviparous Nimba toad, Nimba otter-shrew, and the discrete Bossou chimpanzee population. Dung beetles can act as a focal taxon from which extrapolation to the diversity of other taxa and ecosystem health can be made. Elevational trends in dung beetle diversity were investigated on the Nimba Mountain Range and in the nearby Bossou Chimpanzee reserve in Guinea. Dung beetle species diversity surveys aimed to document …
Clues To Aquatic Beetle Research In Southeast Asia: A Multitude Of Ecological Niches, Microhabitats And Deduced Field Sampling Techniques, Hendrik Freitag
Clues To Aquatic Beetle Research In Southeast Asia: A Multitude Of Ecological Niches, Microhabitats And Deduced Field Sampling Techniques, Hendrik Freitag
Biology Faculty Publications
The basic ecological classification of Southeast Asian beetle families that are associated with aquatic habitats is reviewed. The microhabitat preferences of the taxa are examined on family level with generic examples. Suitable collection methods for quantitative and qualitative sampling are suggested which take into account the different ecological adaptation patterns and microhabitat preferences.
Revision Of Anacaena Thomson, 1859 Xi. Republic Of The Philippines (Coleoptera: Hydrophilidae), Hendrik Freitag
Revision Of Anacaena Thomson, 1859 Xi. Republic Of The Philippines (Coleoptera: Hydrophilidae), Hendrik Freitag
Biology Faculty Publications
The species of Anacaena THOMSON, 1859 (Coleoptera: Hydrophilidae) of the Republic of the Philippines are revised. Fifteen new species are described: Anacaena albay sp.n., A. amplocomata sp.n., A. apo sp.n., A. balabag sp.n., A. cordillera sp.n., A. davao sp.n., A. destructa sp.n., A. emergens sp.n., A. hemisphaerica sp.n., A. levistriata sp.n., A. philippina sp.n., A. princesa sp.n., A. quezona sp.n., A. sulcata sp.n., and A. zamboangana. All species are endemic to the Philippines, twelve are aquatic, the habitat of three species is unknown. All Philippine species are morphologically similar to other species of the eastern Oriental Region and probably do …
A Preliminary, Annotated List Of Beetles (Insecta: Coleoptera) From The Uw-Milwaukee Field Station, Daniel K. Young
A Preliminary, Annotated List Of Beetles (Insecta: Coleoptera) From The Uw-Milwaukee Field Station, Daniel K. Young
Field Station Bulletins
Coleoptera, the beetles, account for nearly 25% of all known animal species, and nearly 18% of all described species of life on the planet. Their species richness is equal to the number of all plant species in the world and six times the number of all vertebrate species. They are found almost everywhere, yet many minute or cryptic species go virtually un-noticed even by trained naturalists. Little wonder, then, that such a dominant group might pass through time relatively unknown to most naturalists, hobbyists, and even entomologists; even an elementary comprehension of the beetle fauna of our own region has …
Ancyronyx Erichson, 1847 (Coleoptera, Elmidae) From Mindoro, Philippines, With Description Of The Larvae And Two New Species Using Dna Sequences For The Assignment Of The Developmental Stages, Hendrik Freitag
Biology Faculty Publications
Ancyronyx buhid sp. n. and Ancyronyx tamaraw sp. n. are described based on adults and larvae, matched using their cox1 or cob DNA sequence data. Additional records of Ancyronyx schillhammeri Jäch, 1994 and Ancyronyx minerva Freitag & Jäch, 2007 from Mindoro are listed. The previously unknown larva of Ancyronyx schillhammeri is also described here, aided by cox1 data. The new species and larval stages are described in detail and illustrated by SEM and stacked microscopic images. Keys to the adult and larval Ancyronyx species of Mindoro and an updated checklist of Philippine Ancyronyx species are provided. The usefulness as bioindicators, …
Hydraena (Hydraenopsis) Ateneo, New Species (Coleoptera, Hydraenidae) And Other Aquatic Polyphaga From A Small Habitat Patch In A Highly Urbanized Landscape Of Metro Manila, Philippines, Hendrik Freitag
Biology Faculty Publications
Seven species of Hydraenidae, Hydrophilidae and Elmidae are recorded from temporary freshwater habitats at the Ateneo de Manila University Campus in the metropolitan area of Manila, Philippines. They were identified as Enochrus (Lumetus) fragiloides d’Orchymont, Helochares (Hydrobaticus) lepidus d’Orchymont, Helochares (Helochares) pallens (MacLeay), Hydraena (Hydraenopsis) scabra d’Orchymont, Hydraena (Hydraenopsis) palawanensis Freitag & Jäch (new record for Luzon Island), Stenelmis sp. A further hydraenid species was unknown to science and is newly described: Hydraena (Hydraenopsis) ateneo Freitag, sp. n. Aedeagus, gonocoxite, spermatheca, and female tergite X are illustrated by …
The Marsh Beetles (Coleoptera: Scirtidae) Of Pine Hollow And The Uw-Milwaukee Field Station, Daniel K. Young
The Marsh Beetles (Coleoptera: Scirtidae) Of Pine Hollow And The Uw-Milwaukee Field Station, Daniel K. Young
Field Station Bulletins
Four species of marsh beetles were collected from Pine Hollow during the 1987 field season. Of these, Prionocyphon discoideus (Say) represents a new state record. In addition, specimens of an undescribed Cyphon were also recovered. During the same period, 12 scirtid species were taken at the UW-Milwaukee Field Station. Of these, new state records are reported for five species of Cyphon: fuscescens Klausnitzer, neovariabilis Klausnitzer, orohreatus KLausnitzer, perplexus Blatchley, and ruficollis (Say). Only two species, Flavohelodes thoracica (Guerin-Meneville) and Cyphon obscurus (Guerin-Meneville), were recovered from both sites. Observational notes are included for each of the species found at the two …
