Abstract:
... Specimens of Salmo trutta (n = 613) captured by local anglers in different rivers in Galicia (NW Spain) during the 2015 fishing season (15 March–15 August) were examined. In total 1479 adult helminths were recovered from the gastrointestinal tracts of 221 fish. Moreover, the microscopic observation of the sediments obtained, previous diphasic concentration, revealed the presence of helminth eggs i ...

EOs have been recognized as important ingredients of plant protection products including insecticidal, acaricidal, fungicidal, and nematicidal agents. Considering the growing importance of EOs as active ingredients, the domestication and cultivation of Medicinal and Aromatic Plants (MAPs) to produce chemically st ...

The present study aims to investigate the effect of Diuron on the meiofaunal assemblages, collected from the Bizerte channel (Tunisia). Microcosm experiments were set up using four increasing Diuron concentrations [D1 (10 ng g⁻¹ dry weight (DW)), D2 (50 ng g⁻¹ DW), D3 (250 ng g⁻¹ DW) and (1250 ng g⁻¹ DW)] compared to non-c ...

Abstract:
... Virtually all examined plant species harbour fungal endophytes which asymptomatically infect or colonize living plant tissues, including leaves, branches, stems and roots. Endophyte-host interactions are complex and span the mutualist–pathogen continuum. Notably, mutualist endophytes can confer increased fitness to their host plants compared with uncolonized plants, which has attracted interest in ...

Abstract:
... Migrations performed by helminths are impressive and diverse, and accumulating evidence shows that many are controlled by sophisticated sensory programs. The migrations of vector-borne helminths are particularly complex, requiring precise, stage-specific regulation. We review the contrasting states of knowledge on snail-borne schistosomes and mosquito-borne filarial nematodes. Rich observational d ...

Abstract:
... Glutamate-gated chloride channels are the most important target of ivermectin and related compounds in parasitic nematodes. A small family of genes encode subunits of these channels, allowing the assembly of multiple channel subtypes; the subunit composition of most of the native receptors is unknown. The members of the gene family vary between species, making extrapolation from C. elegans to para ...

For arthropods, galls provide relative safety from enemies and abiotic stresses while providing nutrition. Galls are formed entirely by the plant, whose transcriptional pathways are modified and coopted to produce a structure specific to the g ...

Abstract:
... Infections with parasitic helminths cause severe debilitating and sometimes lethal diseases in humans and domestic animals on a global scale. Unable to synthesize de novo their own fatty acids and sterols, helminth parasites (nematodes, trematodes, cestodes) rely on their hosts for their supply. These organisms produce and secrete a wide range of lipid binding proteins that are, in most cases, str ...

The basal part of the tube contains a cluster ...

Abstract:
... Why do so many parasitic worms have complex life-cycles? A complex life-cycle has at least two hypothesized costs: (i) worms with longer life-cycles, i.e. more successive hosts, must be generalists at the species level, which might reduce lifetime survival or growth, and (ii) each required host transition adds to the risk that a worm will fail to complete its life-cycle. Comparing hundreds of trop ...

Abstract:
... When a new parasite species is identified, a name-bearing specimen or holotype is designated as its reference standard. For most acanthocephalans and nematodes, the holotype is male, a bias which lacks scientific justification. We propose ways of redressing this imbalance and achieving fuller representation of each species in museum collections. ...

Abstract:
... Priority effects shape the assembly of free‐living communities and host‐associated communities. However, the current literature does not fully incorporate two features of host–symbiont interactions, correlated host responses to multiple symbionts and ontogenetic changes in host responses to symbionts, leading to an incomplete picture of the role of priority effects in host‐associated communities. ...

However, the regulatory function of tardigrades depends on many factors, including their feeding preferences. Yet, tardigrade feeding preferences remain largely unresolved. Therefore, in our experiment, ni ...
