“…It has been nearly three decades since the movement ecology of pest Helicoverpa (previously classified in Heliothis) was last reviewed (47,53). Since then, the field of insect movement ecology has benefited from advances in simulation models (48,93), experimental methods of aerial detection (e.g., optical and radar remote sensing) (18,40), and, particularly, population genetics (3,6,103,120,129). Here, we consider how contemporary experimental and theoretical approaches can be integrated to fill key knowledge gaps and assist management practices.…”

The recent introduction and spread of Helicoverpa armigera throughout South America highlight the invasiveness and adaptability of moths in the Helicoverpa genus. Long-range movement in three key members, H. armigera, H. zea, and H. punctigera, occurs by migration and international trade. These movements facilitate high population admixture and genetic diversity, with important economic, biosecurity, and control implications in today's agricultural landscape. This is particularly true for the spread of resistance alleles to transgenic crops expressing Bacillus thuringiensis (Bt) toxins that are planted over vast areas to suppress Helicoverpa spp. The ability to track long-distance movement through radar technology, population genetic markers, and/or long-distance dispersal modeling has advanced in recent years, yet we still know relatively little about the population trajectories or migratory routes in Helicoverpa spp. Here, we consider how experimental and theoretical approaches can be integrated to fill key knowledge gaps and assist management practices.

“…The models presented represent the possible routes of air masses to the collection site, considered as the last position of the ship during each interval in the route. Modelling using the Hysplit Platform has been widely used in studies linking meteorology and ecology (Parry et al, 2015, Rolph et al 2017, Rivas Jr. et al, 2018).…”

Investigating aerial diversity of non‐fungal eukaryotes across a 40° latitudinal transect using DNA metabarcoding

The high number of bipolar and widespread bryophyte and microbial taxa in the Antarctic flora suggests the effective Long‐Distance Dispersal (LDD) of spores and other propagules from lower latitudes and even the Northern Hemisphere to Antarctica and the sub‐Antarctic regions. However, few studies have attempted to document the transfer mechanisms by which potential newcomers may arrive in Antarctica. Commonly suggested or assumed mechanisms include transport in air currents, adventitious transfer with migrating or vagrant birds, and with human assistance. In this study, we investigated the biodiversity present in the air along a 40° latitudinal transect, from the port city of Rio de Janeiro, Brazil (ca. 22°S) to Comandante Ferraz Station on King George Island (South Shetland Islands, ca. 62°S), maritime Antarctica, to shed light on the potential role of LDD in species distribution. Air samples were collected in October 2021 on the Brazilian polar support vessel Ary Rongel using air filters with membranes of 0.22 μm. Total DNA was extracted from the filters and the Internal Transcribed Spacer (ITS2) DNA sequence was used for metabarcoding. A total of 53 non‐fungal taxa representing three kingdoms (most abundantly Viridiplantae) and six phyla (most abundantly Bryophyta and Magnoliophyta) were assigned from the sequences found. Aerial biodiversity was greater closer to the coast and generally decreased with increasing latitude, although a small increase was apparent in the South Shetland Islands. The taxa assigned are generally present in coastal biomes, although a small proportion of the assignments represented taxa of more distant origin, supporting the occurrence of LDD in the air column.

“…Non-crop elements of the landscape also play an important role when considering organism population dynamics (e.g. Bianchi et al, 2006;Parry et al, 2015). One of the future extensions in ATLAS is taking into account phenology of perennial landscape elements and their potential effects in terms of habitats.…”

The spatially-explicit AgriculTural LandscApe Simulator (ATLAS) simulates realistic spatial-temporal crop availability at the landscape scale through crop rotations and crop phenology. Intended to be linked to organism population dynamics, the simulator is developed in a multi-agent platform. The model relies on initial GIS inputs for landscape composition and configuration. Users define typical rotations and crop phenology stages to be included, according to their objectives. In the study, we present two applications to contrasting landscapes, where ATLAS is capable of simulating accurate composition (crop area) and configuration (crop clustering) dynamics. ATLAS has potential applicability to a range of contrasting agricultural landscapes. The benefits of such a simulator are the possibility to study the effects of various simulated management scenarios of crop spatial-temporal availability in relation to target organisms and/or specific ecological processes (e.g. pest, biological control), within a single model framework.
