Breeding phaseolus vulgaris (common bean) for resistance to the major pest bruchids Zabrotes subfasciatus and Acanthoscelides obtectus. Biochemical bases for seed resistance in wild lines [PDF]
, 1990 Phaseolus vulgaris (common bean) is an important source of protein for human and animal consumption. Economic losses post-harvest in storage are primarily due to the bruchid beetles Acanthoscelides obtectus (Bean Weevil) and Zabrotes subfasciatus ...

Wildlife Biology, EarlyView.Predator control is a widely used management tool worldwide to reduce the impact of opportunistic predatory species, but in some contexts where predators are controlled to reduce negative impacts on game species, there are concerns about the selectivity and efficiency.

Wildlife Letters, EarlyView.We staged dyadic interaction trials between two kangaroo rat species threatened by habitat loss to test whether one species dominates in direct interactions in the field. We found that Stephens’ kangaroo rat (Dipodomys stephensi) residents and intruders were dominant over Dulzura kangaroo rat (Dipodomys simulans). These results suggest that D. simulans

Postdispersal seed predation in a Mediterranean patchy landscape
, 1996 13 páginas, 2 figuras, 3 tablas.Seed predation rates of Pistacia lentiscus (Anacardiaceae) were determined at within and between site spatial scale in an Eastern Spanish Mediterranean landscape, a mosaic of scrubland and field patches.

Wildlife Society Bulletin, EarlyView.We used drone‐based radiotelemetry and multispectral imagery to estimate detection and survival probabilities of blue‐winged teal broods in Saskatchewan, Canada. Weekly brood survival probabilities, estimated via Cormack‐Jolly‐Seber models, increased with age and were comparable between drone methods.

Revista de Biología Tropical, 2009 Pre-dispersal seed predation in three populations of the tree Enterolobium contortisiliquum (Fabaceae). Predation is an important selective force that has shaped different strategies related to size, quantity and production time of fruits, seeds and seed

Wild pigs (Sus scrofa) prefer inoculated peanuts over whole‐kernel corn in cafeteria‐style study
Wildlife Society Bulletin, EarlyView.In this study, we explored bait preference of wild pigs (Sus scrofa), a highly invasive species where primary removal efforts include the use of bait and corral‐style trapping. In addition, we investigated preferences of a common nontarget to identify a bait that is preferred by wild pigs and not by white‐tailed deer (Odocoileus virginianus).

Revista Chilena de Historia Natural, 2008 Pre-dispersal seed predation by Austral parakeets, Enicognathus ferrugineus, on pehuén, Araucaria araucana, was studied to assess the relationship between predation and seed production. We collected falling seeds in four araucaria forests of southwestern

Alternative seed trait strategies are linked to a trade‐off between spatial and temporal dispersal
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Seed dispersal allows plants to seek favourable conditions or spread the risk of unfavourable conditions through space and time. While theory predicts a trade‐off between spatial and temporal dispersal, empirical tests have been stymied by the difficulty of measuring ...

Integrating large mammalian herbivores into Dynamic Global Vegetation Models: Status and next steps
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Zoogeochemistry, the study of how animals influence elemental cycling within ecosystems, bridges the fields of zoology, ecology and biogeochemistry. Yet, most terrestrial ecosystem models, especially Dynamic Global Vegetation Models (DGVMs), remain largely plant‐centric
