The spatial configuration and management of agricultural and other land-use practices can affect ecological assemblages, but how resident and migratory species respond to land uses is not well known, hindering our understanding of the effects of land use on biodiversity. Here, we compare alpha and beta diversity and ecosystem functioning for reside...
As global climate continues to change, so too will phenology of a wide range of insects. Changes in flight season usually are characterised as shifts to earlier dates or means, with attention less often paid to flight season breadth or whether seasons are now skewed. We amassed flight season data for the insect order Odonata, the dragonflies and da...
Fennoscandivian boreal forests have been logged for centuries, yet only since the second world war has management shifted from selective logging to clear-cutting. In general, this shift equates to fewer stands of uneven age and higher vertical complexity and more stands of even age and lower complexity. Ecological responses to this shift in forestr...
We studied hybridization between the Black-crested and Tufted titmouse across two geographically distinct transects that differ in the timing of secondary contact by hundreds to thousands of years. We found that hybridization patterns correspond to localized hybrid swarms and that the titmouse hybrid zone is likely slowly expanding over time, a pro...
Context.
Predicting species’ responses to environmental changes requires assessments of site fidelity as well as an understanding of how individuals move through habitats that may become heterogenous and/or fragmented.
Objectives.
We used translocation experiments to evaluate the functional connectivity of a heterogenous saltmarsh landscape for thr...
Berry-producing Vaccinium shrubs are keystone species in boreal forest ecosystems and their berries provide an essential food source for many vertebrates. In Fennoscandia, both the abundance and cover of Vaccinium have decreased in forests, with intensive forestry practice as a main driver. Vaccinium seedling recruitment is constricted to recruitme...
Long‐term land‐use change impacts tropical bird communities through population‐level and functional diversity effects from habitat loss, degradation and fragmentation, leading to land management and conservation challenges.
Assessing the temporal impacts of land‐use change on occupancy patterns, population change and functional traits of bird speci...
Monitoring parrot populations is of high importance because there is a general lack of quantified population trends for one of the most threatened avian orders. We surveyed parrots in Nicaragua in 1995, 1999, 2004, and 2013 at a minimum of 227 points within 56 sites stratified among the Pacific, Central Highlands, and Caribbean biogeographical regi...
Despite extensive research on passerine reproduction, it remains difficult to predict which traits of individuals, nesting populations and landscapes drive extrapair paternity (EPP). Two broad categories of drivers, habitat structure and population level factors, have been considered separately or at a single spatial or temporal scale. We used a 6-...
This research-level text documents the latest advances in odonate biology and relates these to a broader ecological and evolutionary research agenda. Despite being one of the smallest insect orders, dragonflies offer a number of advantages for both laboratory and field studies. In fact, they continue to make a crucial contribution to the advancemen...

Besides the importance of pigmentation in species recognition, pigments protect the body against different biotic and abiotic features. Melanin, the dark coloration pigments in skin, hairs, and feathers, is necessary for protecting the body from UV radiation. On the other hand, the lighter a surface is, the more solar radiation is reflected. Based...
As body size often predicts energetic requirements and fecundity, understanding the drivers behind size variation is important. Neo‐Bergmann's rule states that larger individuals are found at higher latitudes and this size variation is attributable to temperature gradients. In ectotherms, this macroecological pattern has mixed support within the li...
Climate and human management, such as hay harvest, shape grasslands. With both disturbances co-occurring, understanding how these ecosystems respond to these combined drivers may aid in projecting future changes in grasslands. We used an experimental precipitation gradient combined with mimicked acute hay harvest (clipping once a year) to examine (...
According to the stress gradient hypothesis (SGH), ecological interactions between organisms shift positively as environmental stress increases. In the case of associational resistance, habitat is modified to ameliorate stress, benefitting other organisms. The SGH is contentious due to conflicting evidence and theoretical perspectives, so we adopte...
Habitat selection is a basic aspect of the ecology of many species, yet often the term is conflated or confused with both habitat preference and habitat use. We argue that each term fits within a conceptual framework that can be viewed in Bayesian terms and demonstrate, using long-term data on occupancy patterns of a grassland grouse, how prior pro...
• Climate warming is predicted to have large effects on insects, yet several data shortfalls, including distributional information, impede effective conservation strategies.
• Knowledge of species distributions is a critical component for assessing conservation need but is often lacking for endemic or rare taxa, especially invertebrates.
• One appr...
In clinical cancer medicine, the current inability to quantify intracellular chemotherapy drug concentrations in individual human cells limits the personalization and overall effectiveness of drug administration. New bioanalytical methods capable of real-time measurement of drug levels in live single cancer cells would allow for more adaptive and p...
Insects are reportedly experiencing widespread declines, but we generally have sparse data on their abundance. Correcting this shortfall will take more effort than professional entomologists alone can manage. Volunteer nature enthusiasts can greatly help to monitor the abundance of dragonflies and damselflies (Odonata), iconic freshwater sentinels...
