Life cycle truncation in Digenea, a case study of Neophasis spp. (Acanthocolpidae)

open access: yesInternational Journal for Parasitology: Parasites and Wildlife, 2021
Truncated life cycles may emerge in digeneans if the second intermediate host is eliminated, and the first intermediate host, the mollusc, takes up its role.

Microbiomes In Natura: Importance of Invertebrates in Understanding the Natural Variety of Animal-Microbe Interactions

open access: yesmSystems, 2018
Animals evolved in a world teeming with microbes, which play pivotal roles in their health, development, and evolution. Although the overwhelming majority of living animals are invertebrates, the minority of “microbiome” studies focus on this group ...

Ultrafiltration and Fluid Excretion in Echinoids Involves the Axial Organ with Elimination via the Intestine

open access: yesLife
Many animals display nephridial structures for the ultrafiltration of metabolic waste. However, a nephridial equivalent and an excretory system are not generally recognized for echinoderms.

Macro-Invertebrate Decline in Surface Water Polluted with Imidacloprid

open access: yesPLoS ONE, 2013
Imidacloprid is one of the most widely used insecticides in the world. Its concentration in surface water exceeds the water quality norms in many parts of the Netherlands.

Evolutionary Transition of Promoter and Gene Body DNA Methylation across Invertebrate–Vertebrate Boundary

open access: yesMolecular biology and evolution, 2015
Genomes of invertebrates and vertebrates exhibit highly divergent patterns of DNA methylation. Invertebrate genomes tend to be sparsely methylated, and DNA methylation is mostly targeted to a subset of transcription units (gene bodies).

First endemic freshwater Gammarus from Crete and its evolutionary history—an integrative taxonomy approach [PDF]

open access: yesPeerJ, 2018
The Mediterranean islands are known as natural laboratories of evolution with a high level of endemic biodiversity. However, most biodiversity assessments have focused mainly on terrestrial and marine fauna, leaving the freshwater animals aside. Crete is

Immunohistochemical Characterization of the Nervous System of Culex pipiens (Diptera, Culicidae)

open access: yesBiology, 2022
Arthropod-borne diseases represent one of the greatest infection-related threats as a result of climate change and globalization. Repeatedly, arbovirus-infected mosquitoes show behavioral changes whose underlying mechanisms are still largely unknown, but

Recent advances in the innate immunity of invertebrate animals.

open access: yesJournal of biochemistry and molecular biology, 2005
Invertebrate animals, which lack adaptive immune systems, have developed other systems of biological host defense, so called innate immunity, that respond to common antigens on the cell surfaces of potential pathogens.

Balancing between predation risk and food by boreal breeding ducks

open access: yesEcology and Evolution
Wetlands belong to the globally most threatened habitats, and organisms depending on them are of conservation concern. Wetland destruction and quality loss may affect negatively also boreal breeding ducks in which habitat selection often needs balancing ...
