Data from: Exploitation of the same trophic link favors convergence of larval life-history strategies in complex life cycle helminths
Switching from one host to the next is a critical life history transition in parasites with complex life cycles. Growth and mortality rates are thought to influence the optimal time and size at transmission, but these rates are difficult to measure in parasites. The parasite life cycle, in particular the trophic link along which transmission occurs, may be a reasonable proxy for these rates, leading to the hypothesis that life cycle should shape life history strategy. We compiled data on the size and age at infectivity for trophically-transmitted helminths (i.e. acanthocephalans, cestodes, and nematodes), and then categorized species into trophic links (e.g. planktonic crustaceans to fish, insects to terrestrial vertebrates, etc.). Comparative analyses that explicitly included stabilizing selection within trophic links fit the data significantly better than random walk models, indicating that parasites with different life cycles have different optimal times/sizes for host switching. The major helminth groups have often independently evolved similar life cycles, and we show that this has frequently led to convergent and/or parallel evolution of size and age at infectivity. This suggests that for particular life cycles there are universal optimal transmission strategies, applicable to widely divergent taxa, although the cases of parallelism might indicate that lineage-specific constraints sometimes prevent evolution to a single adaptive peak.
Data from: Mechanisms of biotic resistance across complex life cycles
1. Biotic resistance is the ability of communities to inhibit the establishment, spread or impact of novel species. However, the interactions that underlie biotic resistance depend heavily on the contexts in which species interact. Consequently, studies of biotic resistance that consider single processes, patches, species or life-history stages may provide an incomplete picture of the capacity for communities to resist invasion. 2. Many organisms have multiphasic life cycles, where individuals can occupy distinct niches at different stages of the life-history. Generally, studies of biotic resistance focus on interactions within a single life-history stage, and interactions at other life-history stages are overlooked. Here, we demonstrate that different mechanisms of biotic resistance occur across the life history and together limit the invasion success of an introduced marine invertebrate (Ciona intestinalis) in northern California. 3. We tested the role of interactions (competition and predation) with the resident community in limiting the abundance of Ciona through experiments conducted on fertilization, larval survival, settlement, early post-settlement survival, and the survival of juveniles and adults. 4. Under some circumstances, Ciona became abundant in mid-successional stages and showed more rapid growth rates than a morphologically similar native species, Ascidia ceratodes. However, predators reduced Ciona abundance much more than that of Ascidia at several life stages. 5. Furthermore, Ciona appeared to be a weaker competitor at the adult stage. Early life-history interactions with other sessile species at the fertilization, larval and recruit stages had modest to no effects on Ciona abundance. 6. The presence of biotic resistance mechanisms acting at multiple life stages, and potentially under different conditions, suggests that different components of biotic resistance interact to enhance the resident community's resistance to invasion.

IE Day 24 Poster- Life Cycle Evaluation of Prescription Medication Dispersion in New Jersey
<p>This study investigates the environmental impacts of single-use plastic pill bottles versus refillable glass pill bottles for medication packaging in New Jersey pharmacies using Life Cycle Assessment (LCA) methods. Given the high environmental toll of single-use plastics, transitioning to refillable glass bottles offers potential benefits, despite the energy-intensive production process of glass. The study evaluates both bottle types across various impact categories, including global warming potential, ozone depletion, water consumption, and eco-toxicity, using the ReCiPe 2016 Midpoint (H) assessment method. The results indicate that, while producing a single glass bottle initially incurs a higher environmental cost compared to a single plastic bottle, using one refillable glass bottle over twelve plastic bottles annually results in a notable reduction in environmental impacts. The transportation logistics present additional challenges where customer trips for refilling glass bottles contribute substantially to eco-toxicity and other impact areas, suggesting that further optimization of refilling systems may enhance the overall sustainability of glass as a packaging alternative.</p>

Experimental habitat fragmentation disrupts host-parasite interaction over decades via life-cycle bottlenecks
Habitat loss and fragmentation are likely to seriously impact parasites, a less studied but critical component of ecosystems, yet we lack long-term experimental evidence. Parasites structure communities, increase connectivity in food webs, and account for a large proportion of an ecosystem's total biomass. Food web models predict that parasites with multiple obligate hosts are at greater risk of extinction because the local extinction, or reduction in abundance, of any host will result in a life-cycle bottleneck for the parasite. We examine the response of a parasite and its multiple hosts to forest fragmentation over 26 years in the Wog Wog Habitat Fragmentation Experiment in southeastern Australia. The parasite is the nematode Hedruris wogwogensis, its intermediate host is the amphipod, Arcitalitrus sylvaticus, and its definitive host is the skink, Lampropholis guichenoti. In the first decade after fragmentation, nematodes completely disappeared from the matrix (plantation forestry) and all but disappeared from their definitive host (skinks) in fragments, and by the third decade after fragmentation had not appreciably recovered anywhere in the fragmented landscape compared to continuous forest. The low prevalence of the nematode in the fragmented landscape was associated with the low abundance of one or the other host in different decades: low abundance of the intermediate host (amphipod) in the first decade and low abundance of the definitive host (skink) in the third decade. In turn, the low abundance of each host was associated with changes to the abiotic environment over time due largely to the dynamically changing matrix as the plantation trees grew. Our study provides rare long-term experimental evidence of how disturbance can cause local extinction in parasites with life cycles dependent on more than one host species through population bottlenecks at any life stage. Mismatches in the abundance of multiple hosts over time are likely to be common following disturbance, thus causing parasites with complex life cycles to be particularly susceptible to habitat fragmentation and other disturbances. The integrity of food webs, communities, and ecosystems in fragmented landscapes may be more compromised than presently appreciated due to the sensitivity of parasites to habitat fragmentation.
