Increased Threat of Urban Malaria from Anopheles stephensi Mosquitoes, Africa

open access: yesEmerging Infectious Diseases, 2019
Malaria continues to be a major health threat in Africa, mainly in rural areas. Recently, the urban malaria vector Anopheles stephensi invaded Djibouti and Ethiopia, potentially spreading to other areas of Africa. Urgent action is needed to prevent urban

Environment and Host Genetics Drive Infection Outcomes in a Butterfly Host, but Do Not Interact With Each Other

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
This study examined how host genetics and larval food plant environment influence parasite infection outcomes in monarch butterflies (Danaus plexippus) infected with the protozoan Ophryocystis elektroscirrha. We tested for genotype × environment interactions on infection status, infection burden, lifespan, and wing size.

Diversity and Distribution Patterns of Insects in Nigeria: A GBIF‐Based Appraisal

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
Insect diversity in Nigeria is high, with 5880 species. Diversity differs between biomes. Current diversity represents ~21 of the estimated ‘true’ diversity. ABSTRACT Insects provide essential ecosystem services and are key indicators of ecosystem health.

A Generalizable Tool for Predicting Developmental Phenology for Wild Ecotherms

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
Custom hatch timing models developed for four North American Lithobates frog species. Models are parameterized from Moore (1939). Panels (A, B) shows differential developmental rates under varying thermal regimes and G × E interactions. ABSTRACT Development in poikilothermic organisms is strongly temperature‐dependent, particularly during early life ...

Geostatistical Modelling and Web‐Based Mapping of Malaria Risks Among Children Under Five Years in Nigeria: Evidence From the 2021 Nigeria Malaria Indicator Survey

open access: yesHealth Science Reports, Volume 9, Issue 8, August 2026.
ABSTRACT Background Malaria is a critical public health concern in Nigeria with the country bearing an uneven burden of the disease. In Nigeria, malaria is one of the main causes of child mortality and despite all efforts to reduce malaria mortality rates, the disease remains a major concern, notably among children under‐fives.
