Bugs collected on rooftop for 18 years reveal climate change effects

CLIMATE

A volunteer registration of insects for 18 consecutive years on the roof of the Natural History Museum of Denmark has revealed local insect community turnover due to climate change. The research suggests a pattern of specialised species being more sensitive to climate change.

1543 different species of moths and beetles and more than 250.000 individuals have been registered on a single urban rooftop in Copenhagen over 18 years of monitoring. That corresponds to 42 % of all the species of moths in Denmark and 12 % of the beetles. More interestingly, the insect community has changed significantly during that period. The results are published today in the Journal of Animal Ecology led by researchers from the Center for GeoGenetics and the Center for Macroecology, Evolution and Climate at the Natural History Museum of Denmark at the University of Copenhagen.

“We are likely to lose some specialist species as they retreat north, but more new specialist species will arrive from the south. This trend is theoretically expected but extremely rare to confirm with observations across this many species. Insects are often over-looked and under prioritised for long term studies” says the other lead authorPeter Søgaard Jørgensen, PhD from the Center for Macroecology, Evolution and Climate.

Bedbugs

Both bed bugs and the insects that spread the protozoan that causes Chagas disease are insects of the order Hemiptera. Bugs of this order are commonly referred to in Spanish as chinches, so this is a good name for either. So yes, both bugs are closely related. If you want to differentiate, you can always […]

Both bed bugs and the insects that spread the protozoan that causes Chagas disease are insects of the order Hemiptera. Bugs of this order are commonly referred to in Spanish as chinches, so this is a good name for either.

So yes, both bugs are closely related. If you want to differentiate, you can always be specific (or pedantic!) and use their scientific names; Triatominae (or triatomines) for the Chagas disease vector and Cimex for bed bugs.


Entomology (from Greek ???????, entomos, “that which is cut in pieces or engraved/segmented”, hence “insect”; and -?????, -logia[1]) is the scientific study of insects, a branch of arthropodology, which in turn is a branch of zoology. In the past the term “insect” was more vague, and historically the definition of entomology included the study of terrestrial animals in other arthropod groups or other phyla, such as arachnids, myriapods, earthworms, land snails, and slugs. This wider meaning may still be encountered in informal use.

Like several of the other fields that are categorized within zoology, entomology is a taxon-based category; any form of scientific study in which there is a focus on insect related inquiries is, by definition, entomology. Entomology therefore includes a cross-section of topics as diverse as molecular genetics, behavior, biomechanics, biochemistry, systematics, physiology, developmental biology, ecology, morphology, paleontology, mathematics, anthropology, robotics, agriculture, nutrition, forensic science, and more.

At some 1.3 million described species, insects account for more than two-thirds of all known organisms,[2] date back some 400 million years, and have many kinds of interactions with humans and other forms of life on earth.
