The effect of insect herbivory on the growth and fitness of introduced Verbascum thapsus L [PDF]

open access: yesNeoBiota, 2013
A majority of the plant species that are introduced into new ranges either do not become established, or become naturalized yet do not attain high densities and are thus considered ecologically and economically unproblematic. The factors that limit these

Common mullein, pharmacological and chemical aspects [PDF]

open access: yesRevista Brasileira de Farmacognosia, 2013
AbstractVerbascum thapsus L. [Khardhag or Common mullein], a member of the family Scrophulariaceae, is a famous herb that is found all over Europe, in temperate Asia, in North America and is well-reputed due to its medicinal properties. This medicinal herb contains various chemical constituents like saponins, iridoid and phenylethanoid glycosides ...

Mullein it over: an examination of the impacts of common mullein (Verbascum thapsus) invasion and management [PDF]

open access: yes, 2015
Biological invasion is one of the most important problems facing modern ecologists, and while research has shown the detrimental effects caused by many invasive species, the impact of the majority of invaders in largely unknown. I investigated the effects of the ubiquitous exotic plant species common mullein (Verbascum thapsus) on plant communities in ...

Population and leaf-level variation of iridoid glycosides in the invasive weed Verbascum thapsus L. (common mullein): implications for herbivory by generalist insects [PDF]

open access: yesChemoecology, 2012
Plant–insect interactions, which are strongly mediated by chemical defenses, have the potential to shape invasion dynamics. Despite this, few studies have quantified natural variation in key defensive compounds of invasive plant populations, or how those defenses relate to levels of herbivory.

The dark web trades wildlife, but mostly for use as drugs

open access: yesPeople and Nature, Volume 5, Issue 3, Page 999-1009, June 2023., 2023
Abstract Contemporary wildlife trade is massively facilitated by the Internet. By design, the dark web is one layer of the Internet that is difficult to monitor and continues to lack thorough investigation. Here, we accessed a comprehensive database of dark web marketplaces to search across c. 2 million dark web advertisements over 5 years using c. 7 k

Plant and mule deer responses to pinyon‐juniper removal by three mechanical methods

open access: yesWildlife Society Bulletin, Volume 47, Issue 2, June 2023., 2023
Mechanical tree removal by any of 3 methods (mastication, chaining, and roller‐chopping) can increase mule deer forage relative to control plots. However, chaining and roller‐chopping were more frequented by mule deer in winter, likely because vertical structure provided enhanced security cover from these treatment methods.

Vegetation complexity and nesting resource availability predict bee diversity and functional traits in community gardens

open access: yesEcological Applications, Volume 33, Issue 2, March 2023., 2023
Abstract Urban gardens can support diverse bee communities through resource provision in resource poor environments. Yet the effects of local habitat and landscape factors on wild bee communities in cities is still insufficiently understood, nor is how this information could be applied to urban wildlife conservation.

Lygus rugulipennis on chrysanthemum: Supplemental prey effects and an evaluation of trap plants

open access: yesJournal of Applied Entomology, Volume 147, Issue 2, Page 157-166, March 2023., 2023
Abstract The European tarnished plant bug, Lygus rugulipennis Poppius, is considered a major pest in chrysanthemum nurseries in The Netherlands. Adults puncture plant's apical meristem, after which the growing point splits and growth is inhibited. Flower buds and flowers can also be severely damaged.

Biological control needs evolutionary perspectives of ecological interactions

open access: yesEvolutionary Applications, Volume 15, Issue 10, Page 1537-1554, October 2022., 2022
Abstract While ecological interactions have been identified as determinant for biological control efficiency, the role of evolution remains largely underestimated in biological control programs. With the restrictions on the use of both pesticides and exotic biological control agents (BCAs), the evolutionary optimization of local BCAs becomes central ...

Chemical and mechanical defenses vary among maternal lines and leaf ages in Verbascum thapsus L. (Scrophulariaceae) and reduce palatability to a generalist insect.

open access: yesPLoS ONE, 2014
Intra-specific variation in host-plant quality affects herbivore foraging decisions and, in turn, herbivore foraging decisions mediate plant fitness. In particular, variation in defenses against herbivores, both among and within plants, shapes herbivore ...
