Multiple developmental pathways in organisms with developmentally complex life cycles

open access: yesFrontiers in Cell and Developmental Biology
One aspect under which an organism’s life cycle can be considered complex is when the very same organism can undertake, or obligatorily undertakes, multiple developmental pathways. Examples are organisms with alternation of generations, like most plants,

Lack of parthenogenesis by Amblyomma cajennense (Acari: Ixodidae)

open access: yesMemorias do Instituto Oswaldo Cruz, 2002
Some reproductive parameters of adult stages of Amblyomma cajennense ticks were studied. The capacity of virgin females to reproduce by parthenogenesis was evaluated, during an experimental infestation, in absence of males, on a horse (Equus cabalus ...

Environmental filtering and spatial structuring differ among body‐size and reproductive‐mode groups of microcrustacean zooplankton in hardwater lakes

open access: yesLimnology and Oceanography, Volume 71, Issue 10, October 2026.
Abstract Local environmental factors are considered primary drivers of lake zooplankton community assembly, yet the roles of landscape factors and dispersal processes remain underexplored. We examined 78 hardwater lakes across the northern Great Plains (Canada) to evaluate how local (water chemistry, morphometric, and catchment characteristics ...

Rainforest conversion to monoculture plantations restructures functional communities of braconid parasitoid wasps

open access: yesOikos, Volume 2026, Issue 10, October 2026.
The conversion of rainforests into rubber and oil palm plantations drives biodiversity loss in Southeast Asia. Parasitoid wasps are highly diverse and play an essential role in ecosystems by regulating herbivore populations. Declines in density and diversity of parasitoid wasps, after land‐use change is well‐documented, but potential functional losses ...

Nanomaterials' Multigenerational Effects by Single and Joint Exposure in Non‐mammalian Models

open access: yesEnvironmental Toxicology, Volume 41, Issue 10, Page 957-974, October 2026.
ABSTRACT Nanotoxicology has mainly focused on single‐generation studies, leaving multigenerational toxicity underexplored. Having animal welfare recently gained importance, we aimed to provide the state‐of‐the‐art of knowledge about multigenerational effects in non‐mammalian models in the case of nanomaterials (NM) single and joint exposure to other ...

Does ecology shape geographical parthenogenesis? Evidence from the facultatively parthenogenetic stick insect Megacrania batesii

open access: yesEcology and Evolution
Closely related sexual and parthenogenetic species often show distinct distribution patterns, known as geographical parthenogenesis. Similar patterns, characterized by the existence of separate sexual and parthenogenetic populations across their natural ...

Gems of the Middle‐East: Unravelling the Biodiversity of Monogonont Rotifers in Temporary and Semi‐Perennial Freshwater Habitats Across Israel

open access: yesFreshwater Biology, Volume 71, Issue 10, October 2026.
ABSTRACT In temporary waterbodies such as ponds, pools and small lakes, the diversity of smaller invertebrates, such as rotifers, remains understudied, despite their ecological importance as prey and decomposers of organic matter. Especially in regions such as Israel, where natural lakes are scarce, temporary waterbodies become even more important as ...
