Phylum Platyhelminthes

open access: yes, 2015
The flatworms of the phylum Platyhelminthes comprise free-living (“Turbellaria”) and obligate parasitic organisms (Monogenea, Digenea, Aspidogastrea, and Cestoda, today grouped in Neodermata). “Turbellaria” includes an amazing variety of forms, but built in a similar way.

Dendritic Cell Migration: An Essential Step in Initiating Adaptive Immunity Across Tissues

open access: yesImmunological Reviews, Volume 337, Issue 1, January 2026.
ABSTRACT Immune surveillance of tissues is primarily carried out by dendritic cells (DCs), which act as sentinels for the adaptive immune system. To accomplish this task, DCs migrate from tissues to regional lymph nodes, or from blood‐exposed regions of the spleen to the white pulp, to prime T cell responses. DC migration is a tightly regulated process

Quo Vadis Venomics? A Roadmap to Neglected Venomous Invertebrates

open access: yesToxins, 2014
Venomics research is being revolutionized by the increased use of sensitive -omics techniques to identify venom toxins and their transcripts in both well studied and neglected venomous taxa.

DNA Metabarcoding Reveals Tardigrades' Diversity and Dispersal Patterns in European Freshwater Rock Pools

open access: yesJournal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim Freshwater rock pools are ephemeral and fragile habitats that support specialised animal taxa. While distributed worldwide, these habitats are usually neglected and overlooked. We used DNA metabarcoding and metaphylogeographic approaches to study inter and intraspecific tardigrade biodiversity to identify their biogeographic patterns to ...

Back to life after 50 years: effects of environmental flow restoration on macroinvertebrate biodiversity and river ecological status. A case study of the Valseco stream, Spain

open access: yesRestoration Ecology, Volume 34, Issue 1, January 2026.
The construction of dams and reservoirs to meet increasing water and electricity demands has significantly altered many natural river flows, posing threats to the ecological integrity of freshwater ecosystems. Environmental flows (e‐flows) have been advocated to mitigate the negative impacts of hydroelectric power generation and to maintain healthy ...

Kicking in the guts: Schistosoma mansoni digestive tract proteins are potential candidates for vaccine development

open access: yesFrontiers in Immunology, 2015
Schistosomiasis is a debilitating disease that represents a major health problem in at least 74 tropical and subtropical countries. Current disease control strategies consist mainly of chemotherapy which cannot prevent recurrent re-infection of people ...

Praziquantel: its use in control of schistosomiasis in sub-Saharan Africa and current research needs [PDF]

open access: yes, 2009
Treatment with praziquantel (PZQ) has become virtually the sole basis of schistosomiasis control in sub-Saharan Africa and elsewhere, and the drug is reviewed here in the context of the increasing rate that it is being used for this purpose. Attention is

Aging as a Loss of Goal‐Directedness: An Evolutionary Simulation and Analysis Unifying Regeneration with Anatomical Rejuvenation

open access: yesAdvanced Science, Volume 12, Issue 46, December 11, 2025.
The paper proposes that the root cause of aging is the loss of anatomical goal‐directedness after development. Using evolutionary neural cellular automata simulations, the authors show that after the organism has reached its developmental homeostatic setpoint (the adult morphology), the absence of target state to pursue leads to a drifting anatomical ...

Phylum Platyhelminthes

open access: yes, 2020
Thorp and Covich's Freshwater Invertebrates, Volume 5: Keys to Neotropical and Antarctic Fauna, Fourth Edition, covers inland water invertebrates of the world. It began with Ecology and General Biology, Volume One (Thorp and Rogers, editors, 2015) and was followed by three volumes emphasizing taxonomic keys to general invertebrates of the Nearctic ...
