Data from: Hidden island endemic species, and their implications for cryptic speciation within soil arthropods

Aim: Specialisation to the soil environment is expected to constrain the spatial scale of diversification within animal lineages. In this context, the existence of flightless arthropod lineages, adapted to soil environments, but with broad geographic ranges, represent something of an anomaly. Here we investigate the diversification process within one such 'anomalous' soil specialist: Geomitopsis franzi Coiffait, 1978, an eyeless and flightless beetle species strongly adapted to the endogean environment but distributed across several oceanic islands. Location: Canary Islands Taxon: Geomitopsis (Coleoptera, Staphylinidae) Methods: We performed an integrative study, including molecular phylogenetics, population genomics, and morphometry. Four DNA regions (two mitochondrial and two nuclear) were amplified and sequenced for 159 specimens from 58 localities sampled across five islands for phylogenetic analyses, and a dated phylogenetic tree was obtained using a mitogenome dataset. ddRAD-seq data was generated to evaluate mtDNA lineages in sympatry against the biological species concept. Results: We found high levels of genetic differentiation (>8% COI gene divergence) among populations from different islands and among geographically coherent lineages within single islands. Lineages within Tenerife presented significant patterns of isolation by distance, with ddRAD-seq providing evidence that lineages represent biological species. Morphometric analyses revealed limited variation, with most lineages lacking diagnostic characters. Main conclusions: Geomitopsis franzi is comprised of at least seven lineages that merit consideration as biological species, and is best considered as a complex of cryptic species. The limited morphological variation across these lineages is consistent with adaptation to the endogean environment placing strong constraints on morphological change. The evolution of cryptic species should be favoured when such constraints are coupled with limited dispersal ability, which characterises G. franzi, and is a trait that broadly characterises the soil mesofauna. We suggest that cryptic species diversity is likely to be a recurrent feature across soil adapted arthropod species with range sizes that appear inconsistent whith a low potential for dispersal.

Data from: Changes in waterfowl migration phenologies in central North America: implications for future waterfowl conservation

Globally, migration phenologies of numerous avian species have shifted over the past half-century. Despite North American waterfowl being well researched, published data on shifts in waterfowl migration phenologies remain scarce. Understanding shifts in waterfowl migration phenologies along with potential drivers is critical for guiding future conservation efforts. Therefore, we utilized historical (1955–2008) nonbreeding waterfowl survey data collected at 21 National Wildlife Refuges in the mid- to lower portion of the Central Flyway to summarize changes in spring and autumn migration phenology. We examined changes in the timing of peak abundance from survey data at monthly intervals for each refuge and species (or species group; n = 22) by year and site-specific temperature for spring (Jan–Mar) and autumn (Oct–Dec) migration periods. For spring (n = 187) and autumn (n = 194) data sets, 13% and 9% exhibited statistically significant changes in the timing of peak migration across years, respectively, while the corresponding numbers for increasing temperatures were 4% and 9%. During spring migration, ≥80% of significant changes in the timing of spring peak indicated advancements, while 67% of significant changes in autumn peak timing indicated delays both across years and with increasing temperatures. Four refuges showed a consistent pattern across species of advancing spring migration peaks over time. Advancements in spring peak across years became proportionally less common among species with increasing latitude, while delays in autumn peak with increasing temperature became proportionally more common. Our study represents the first comprehensive summary of changes in spring and autumn migration phenology for Central Flyway waterfowl and demonstrates significant phenological changes during the latter part of the twentieth century.

Home range sizes of red deer in contrasting landscapes and implications for management

Knowledge about deer spatial use is essential for damage mitigation and management coordination. Here we assess annual and seasonal home range sizes for red deer in Sweden, based on data from GPS-marked deer in two regions with different management systems and contrasting landscapes. We compare our findings with reviewed data on European red deer (Cervus elaphus) home range sizes in Europe. We found that female annual home ranges (95% kernels) were 2.7 times larger in a mixed agricultural-forest landscape compared to a forest-dominated landscape. Core areas (50% kernels) were approximately 1/5 of the full annual home ranges (90% kernels) regardless of region. Home range size in the forest landscape showed little inter-seasonal variation whereas in the agricultural-forest landscape, home ranges were significantly larger during calving, hunt, and winter-spring compared to summer and rut. In the forest landscape, females had home range sizes that enables single red deer management areas to manage their own females. Whereas, within the agricultural-forest landscape, female spatial use cover several license units. Here, the coordinated license system is needed to reach trade-offs between goals of conservation, game management, and damage mitigation. Males had in general larger home ranges than females. The majority of the males made a seasonal migration to and from the rutting areas. The license system in the agricultural-forest landscape is large enough to manage migrating males, but in the forest landscape a coordination of several deer management areas is needed in order to encompass male spatial use.
