Answering key bumble bee conservation questions by studying discovered wild nests: A Bombus affinis case study

open access: yesInsect Conservation and Diversity, Volume 18, Issue 3, Page 303-318, May 2025.
The information learned from discovered wild bumble bee nests can be of great conservation value if studied in situ and post‐season excavation in a standardised way. We provide standardised guidance to follow when nest discoveries arise, including key conservation questions and methodological guidelines to study behaviour, floral use, genetics, body ...

Molecular phylogeny of the Lecudinoidea (Apicomplexa): A major group of marine gregarines with diverse shapes, movements and hosts

open access: yesJournal of Eukaryotic Microbiology, Volume 71, Issue 6, November/December 2024.
Abstract Gregarine apicomplexans are ubiquitous endosymbionts of invertebrate hosts. Despite their ecological and evolutionary importance, inferences about the phylogenetic relationships of major gregarine groups, such as the Lecudinidae and Urosporidae, have been hindered by vague taxonomic definitions and limited molecular and morphological data.

Organic farming and annual flower strips reduce parasite prevalence in honeybees and boost colony growth in agricultural landscapes

open access: yesJournal of Applied Ecology, Volume 61, Issue 9, Page 2146-2156, September 2024.
Landscape features can affect pollinators directly through the provision of food resources and indirectly through modulation of parasite prevalence. To promote honeybee colony health in agro‐ecosystems, our results suggest that organic agriculture and annual flower strips should be prioritized conservation measures. Landscape management should consider

Identification of a new gregarine parasite associated with mass mortality events of freshwater pearl mussels (Margaritifera margaritifera) in Sweden

open access: yesJournal of Eukaryotic Microbiology, Volume 71, Issue 3, May/June 2024.
Abstract Freshwater bivalves play key ecological roles in lakes and rivers, largely contributing to healthy ecosystems. The freshwater pearl mussel, Margaritifera margaritifera, is found in Europe and on the East coast of North America. Once common in oxygenated streams, M.

Lipid reserves and immune defense in healthy and diseased migrating monarchs Danaus plexippus

open access: yesCurrent Zoology, 2013
Recent studies suggest that the energetic demands of long-distance migration might lower the pool of resources available for costly immune defenses. Moreover, migration could amplify the costs of parasitism if animals suffering from parasite-induced ...

Host and floral communities shape parasite prevalence and reproduction in intensively managed forests

open access: yesEcosphere, Volume 15, Issue 1, January 2024.
Abstract Understanding how working landscapes can maintain viable wildlife populations is key to evaluating their conservation potential. We assessed the potential of intensively managed conifer forests for supporting healthy, productive bee populations in one of the major timber‐growing regions of the world, the Pacific Northwest.

Distribution and occurrence of the neogregarine pathogen, Ophryocystis anatoliensis (Apicomplexa) in populations of Chrysomela populi L. (Coleoptera: Chrysomelidae)

open access: yesActa Protozologica, 2017
Chrysomela populi L. (Coleoptera; Chrysomelidae) is one of the most serious pests affecting poplars. Chemical control is the most widely known suppressive method against this pest. This method is not acceptable in urban forests because of their proximity to people.

A New Neogregarine Pathogen Of Rhizophagus Grandis (Coleoptera: Monotomidae)

open access: yes, 2012
Here we provide the first description of a natural infection of members of the beetle family Monotomidae with neogregarines and specifically the first finding of such a pathogen in the predatory beetle Rhizophagus grandis. The fat body of the beetle is the site of infection, and the typical navicular oocysts are 11.87 +/- 0.67 pm in length and 6.96 +/-
