Nutrient addition, but not vertebrate predator exclusion, shapes arthropod communities and herbivory in a temperate forest

Ecological Entomology, EarlyView.
We experimentally manipulated top‐down (predator exclusion) and bottom‐up (fertilisation) forces in a temperate forest understory to test effects on arthropod densities, body sizes and herbivory. Predator exclusion had no detectable effect on arthropod density, herbivory damage or body size, whereas fertilisation increased herbivory damage and ...

Strong diel variation in the activity of insect taxa sampled by Malaise traps

Ecological Entomology, EarlyView.
Malaise traps sampled different communities during mornings (06:00–12:00), afternoons (12:00–16:00), evenings (18:00–22:00), and nights (22:00–06:00), highlighting the difference in diel rhythm between taxa. The highest diversity and abundance of insects were found during afternoons, the lowest diversity during night, and the lowest abundance during ...

Bee community and trait‐based responses to fire in a Mediterranean landscape

Insect Conservation and Diversity, EarlyView.
Fire drives a short‐term increase in bee abundance and diversity, despite its strong negative impact on floral resources. Acting as an environmental filter, fire shapes bee communities as increased post‐fire fine‐scale heterogeneity favors bees with specific functional traits such as ground‐nesting and generalist species.

Differential response in the acicular anatomy of Pinus caribaea var. Caribaea and Pinus tropicalis (Pinaceae) in sympatry

Revista Cubana de Ciencias Forestales, 2022
Pinus caribaea var. caribaea and Pinus tropicalis are the two species of the genus Pinus that form the pine forests of western Cuba, either in pure stands or in sympatry.

Integrative taxonomy supports DNA barcoding in revealing an abundant cryptic species in the United States Coastal Plain

Journal of Systematics and Evolution, EarlyView.
We present the most densely sampled phylogeny of Carex section Lupulinae to date (107 specimens) and describe herein a new cryptic species for science from the southern United States, which is locally abundant and found in well‐explored and densely populated areas. Combining DNA sequences with morphometric data obtained from 299 samples, we Demonstrate

Compatibility and ectomycorrhiza formation among Pisolithus Isolates and Eucalyptus spp Compatibilidade e formação de Ectomicorrizas entre Isolados de Pisolithus e Eucalyptus spp

Revista Brasileira de Ciência do Solo, 2005
Twenty-nine isolates of the ectomycorrhiza fungus Pisolithus sp. from different geographical and host origins were tested for their ability to form ectomycorrhizae on Eucalyptus grandis and E. urophylla seedlings under greenhouse conditions.

Shrubs and trees as natural insect protection for grazing animals in Switzerland and the alpine region: A systematic review of in vitro, in vivo and clinical trials Sträucher und Bäume als natürlicher Insektenschutz für Weidetiere in der Schweiz und im Alpenraum: Eine systematische Literaturübersicht über in vitro‐, in vivo‐ und klinische Studien

Medical and Veterinary Entomology, EarlyView.
Biting or irritating insects are a threat to the health and welfare of grazing animals. This systematic review reveals that several shrubs and bushes growing in the alpine area have insecticidal, insect‐repellent and/or attractant properties. The alder Alnus glutinosa, juniper Juniperus communis, spruce Picea abies and walnut Juglans regia are ...

Effects of Self-Pollination in the Genus Pinus

, 1980
The problems of self-pollination among trees are a major concern to foresters. Silvicultural practices have an effect on the frequency of self-pollination.For example, a cut, such as a shelterwood or seed tree, reduces the number of individuals in the breeding population and increases the distance between individual trees.

Longevity in plants impacts phylogenetic and population dynamics

New Phytologist, EarlyView.
Summary Phylogenies of long‐lived plants often exhibit short molecular branch lengths and high levels of gene‐tree conflict. However, the biological mechanisms underlying these patterns remain unclear. We examine this with simulations and through empirical examination of several large seed plant clades.
