Data for: Small reductions in cargo vessel speed dramatically reduce noise impacts to marine mammals

Global reductions in the underwater radiated noise levels from cargo vessels are needed to reduce increasing cumulative impacts to marine wildlife. We use a vessel exposure simulation model to examine how reducing vessel source levels through slowdowns and technological modifications can lessen impacts on marine mammals. We show that the area exposed to ship noise reduces dramatically with moderate source level reductions that can be readily achieved with small reductions in speed. Moreover, slowdowns reduce all impacts to marine mammals despite the longer time that a slower vessel takes to pass an animal. We conclude that cumulative noise impacts from the global fleet can be reduced immediately by slowdowns. This solution requires no modification to ships and is scalable – from local speed reductions in sensitive areas to ocean basins. Speed reductions can be supplemented by routing vessels away from critical habitats and by technological modifications to reduce vessel noise.

Data for Simulating the seeder-feeder impacts on cloud ice and precipitation over the Alps

The ice phase impacts many important cloud properties and the lifetime of the clouds. Ice particles that sediment into a lower cloud from an upper cloud (external seeder-feeder process) or into the mixed-phase region of a deep cloud from cirrus levels (internal seeder-feeder) can amplify cloud glaciation and enhance surface precipitation. Recently, numerical weather prediction modeling studies have aimed at representing the ice crystal number concentration in mixed-phase clouds more accurately by including secondary ice formation processes. The increase in the ice crystal number concentration can impact the number of ice particles that sediment into the lower cloud and alter its composition and precipitation formation.  In the Swiss Alps, the orography permits the formation of orographic clouds, making it ideal for studying the occurrence of multi-layered clouds and the seeder-feeder process. We present results from a case study on May 18, 2016, showing the occurrence frequency of multi-layered clouds and the seeder-feeder process. We included ice-graupel breakup to enhance the ice crystal number concentration and investigate the precipitation formation processes. 47.6\% of all observed clouds were categorized as multi-layered, in which the external seeder-feeder process occurred in 10.3\% of these clouds which is similar to what was found in several studies. In between cloud layers, 58.4\% of the ice particle mass was lost due to sublimation or melting. The external seeder-feeder process was found to be more important, with regard to the impact on precipitation, than the internal seeder-feeder process in this case study. In the case where the external seeder-feeder process was blocked, the average surface precipitation and riming rate over the domain were both reduced by 8.5\% and 3.9\%, respectively. When ice-graupel collisions were allowed, further large reductions were seen in the liquid water fraction and riming rate. Blocking of the internal seeder-feeder process enhanced the liquid water fraction of 6\% compared to a reduction of 5.8\% in the cloud condensate and, therefore, pointing towards the deamplification in cloud glaciation and a reduction in surface precipitation.

Impacts of fungal disease on dyadic social interactions in a wild agamid lizard

Emerging infectious fungal diseases are responsible for the extinction of myriad species across a range of phyla. As recently shown by the COVID-19 pandemic, social transmission can be key to disease spread, and in this context, humans are not alone in trying to be alone. In group-living species, individuals have been shown to use social behaviour to avoid infection; diseased individuals can isolate from the group, or healthy animals can avoid diseased conspecifics. However, to date, little is known about social behaviour as a mechanism to avoid fungal infection. In this study, we investigate the extent to which wild urban eastern water dragons (Intellagama lesueurii), a gregarious reptile, modify their social behaviour as a response to infection with a recently emerged infectious fungal disease, caused by the pathogen Nannizziopsis barbatae. Using individual data from a long-term study population inhabiting Roma Street Parkland in Brisbane's Central Business District (QLD, Australia) and focal sampling, we test whether dragons exhibit self-isolation and social distancing behaviours in the context of dyadic social approach events. Statistical analyses of data collected from 633 observations of 123 unique individuals (78 non-diseased, 45 diseased) during 2020 – 2021 suggested that while the presence of the fungal disease had no effect on individuals' social behaviour, the severity of the fungal disease did significantly affect individuals' social behaviour. Specifically, we found that (i) diseased individuals were no less social than their non-diseased conspecifics, (ii) non-diseased individuals did not avoid or spend less time with diseased conspecifics, and (iii) models considering the severity of skin lesions caused by Nannizziopsis barbatae, instead of their presence or absence, suggested that individuals avoided more severely diseased conspecifics regardless of their own disease status. These findings warrant further investigation, given the evidence that many species have displayed behavioural adaptations to disease, and the increasing risk posed by emerging infectious fungal diseases.

Agronomic and quality impact of a shortened translocation for wheat streak mosaic virus resistance

Wheat streak mosaic virus (WSMV) is a mite-vectored virus with substantial economic impact on wheat production. One of the effective sources of resistance to WSMV, Wsm1, is carried on a translocation from Thinopyrum intermedium. The original whole arm form of this translocation (T4DL·4JsS) was highly effective against WSMV but carried a substantial yield penalty in the absence of the virus. Shorter recombinants of the Th. intermedium translocation are now available. This study characterized the agronomic performance of near-isogenic sib-pair families in ten yield trials using one of these shortened T4DL·4DS-4JsS translocations, named 'rec213', in the absence of visible disease. This translocation had no effect on heading date, was associated with a modest reduction (≤ 4.8 cm) in plant height, and the translocation had a favorable effect (≤ 12.6%) on grain yield in those environments where highly significant genotype effects were detected. The translocation did not affect protein concentration or lactic acid-sodium dodecyl sulfate solvent retention capacity, a measure of gluten quality. However, families with the translocation had slightly (≤ 5%) lower protein quality scores than paired families without the translocation. We do not expect this modest difference in quality to be a barrier to utilization of the rec213 translocation for Wsm1, but we encourage breeders to work within high quality genetic backgrounds in when using the rec213 translocation, and to monitor the quality of breeding selections. Improved codominant PCR-based marker assays were developed to facilitate the use of the rec213 Wsm1 trait in breeding programs.

Use of density-impact functions to inform and improve the environmental outcomes of feral horse management

The available science often demonstrates the need for feral horse population control but not the degree of control required to achieve environmental conservation objectives. To better manage the influence of feral horses, we must first understand the relationship between feral horse density and environmental impact. We recorded vegetation and soil disturbance, and the sign of potential causes of this impact in two parts of the Australian Alps, the Bogong High Plains (BHP) and the Eastern Victorian Alps (EVA). We calculated density-impact functions to assist managers with determining feral horse density targets for control programmes. Minimal sign of feral horse impact was detected on the BHP, with no impact of feral horses observed along 99% of the length of transects. In contrast, impacts assigned to feral horses were significantly higher in the EVA, where a larger, higher-density population of feral horses existed. However, greater than 83% of the walked transect length was still undisturbed by feral horses in the EVA. We detected a threshold of horse impact at ~250 horse faecal piles per ha. Above this threshold, a slight increase in horse density resulted in a disproportionately large increase in impact. In this context, a relatively small population control effort may substantially reduce direct horse impact. But where horse densities exist below this threshold, considerably more expense and control effort (resulting from the difficulties related to control at low density) is likely to make very little difference to an already low level of direct impact. The combined impacts associated with the sign of deer, feral pigs, fire and humans were large compared to that of feral horses. Management of feral horses to reduce their direct impact is unlikely to be beneficial without complementary management to reduce the effects of these other agents of impact.

Habitat differences influence genetic impacts of human land use on the American beech (Fagus grandifolia)

Natural reforestation after regional forest clearance is a globally common land-use sequence. The genetic recovery of tree populations in these recolonized forests may depend on the biogeographic setting of the landscape, for instance whether they are in the core or in the marginal part of the species' range. Using data from 501 individuals genotyped across 7 microsatellites, we investigated whether regional differences in habitat quality affected the recovery of genetic variation in a wind-pollinated tree species, American beech (Fagus grandifolia) in Massachusetts. We compared populations in forests that were recolonized following agricultural abandonment to those in remnant forests that have only been logged in both central inland and marginal coastal regions. Across all populations in our entire study region, recolonized forests showed limited reduction of genetic diversity as only observed heterozygosity was significantly reduced in these forests (H O = 0.520 and 0.590, respectively). Within inland region, this pattern was observed, whereas in the coast, recolonized populations exhibited no reduction in all genetic diversity estimates. However, genetic differentiation among recolonized populations in marginal coastal habitat increased (F st logged = 0.072; F st secondary = 0.249), with populations showing strong genetic structure, in contrast to inland region. These results indicate that the magnitude of recovery of genetic variation in recolonized populations can vary at different habitats.

Data from: Integrating ecological niche and hydrological connectivity models to assess the impacts of hydropower plants on an endemic and imperiled freshwater turtle

We built this dataset to assess the impacts of hydropower plants on the distribution of an endemic and imperiled freshwater turtle with very unique ecological requirements, the Williams' side-necked turtle (Phrynops williamsi). To prevent and mitigate impacts, we prioritized sites for species conservation by classifying planned HPP locations according to their predicted adverse effects on species distribution. The dataset has two files: i) species occurrence records and ii) hydropower plant data. The first dataset was fully built by the authors and the second was modified from the Brazilian Electricity Regulatory Agency (ANEEL) georeferenced data system.

Incomplete reproductive barriers and genomic differentiation impact the spread of resistance mutations between green- and red-colour morphs of a cosmopolitan mite pest

We studied patterns of genetic differentiation and barriers to gene flow within and between morphs of T. urticae in order to understand the factors that influence the spread of resistance mutations across its populations. We derived multiple iso-female lines from Tetranychus populations collected from agricultural crops. We generated genomic and morphological data, characterized their bacterial communities, and performed controlled crosses.

Physiological impacts of chronic and experimental Plasmodium infection on breeding-condition male songbirds

This file contains data for an experimental inoculation project aimed at understanding physiological impacts of Plasmodium in breeding-condition songbirds. The 'readme' tab contains explanations for columns on each spreadsheet. We first compared metrics of health (mass, scaled mass, hematocrit, activity rate) and reproductive readiness (cloacal protuberance volume, maximum testosterone concentration in plasma) in male songbirds (Dark-eyed junco, Junco hyemalis hyemalis) with and without chronic Plamodium infections. Then, we quantified the change in these metrics following experimental inoculation with Plasmodium, and asked whether these changes varied between males with and without chronic Plasmodium infections.
