Sampling methods for square and boll-feeding plant bugs (Hemiptera: Miridae) occurring on cotton, Gossypium hirsutum L., were compared with the intent to assess if one approach was viable for two species occurring from early-season squaring to late bloom in 25 fields located along the coastal cotton growing region of south Texas. Cotton fleaphopper, Pseudatomoscelis seriatus (Reuter), damages s...

Although most biological invasions are not successful, relatively few studies have examined otherwise notorious invaders in systems where they are not highly problematic. The annual grass Bromus tectorum is a dominant invader in western North America, but is usually confined to human-dominated and disturbed systems (e.g. roadsides and parking lots) in the East where it remains virtually unstudi...

The relations between a large number of scientific subdisciplines within the population biology of plants are presented. This overview in which the holistic and reductionistic approaches are discussed, emphasizes that conflicts between both attitudes are artificially raised. In fact, the one approach must support the other in order to trace the relations between the individual plants and their ...

Studies on pollination networks have provided valuable information on the number, frequency, distribution and identity of interactions between plants and pollinators. However, little is still known on the functional effect of these interactions on plant reproductive success. Information on the extent to which plants depend on such interactions will help to make more realistic predictions of the...

Seed dispersal is a key determinant of species distribution, although it still unclear how contributes to assembly in plant communities. We linked patterns seed coexisting investigate the role process. focused on 19 foredune community, classified as “foredune foundation species”, “semi-fixed dune species,” and “alien species”. The number seeds dispersed by was monitored monthly 25 plots for 12 ...

Communities dominated by Baccharis pilularis (coyote brush) are expanding in coastal California, altering fuel load on a landscape scale, yet there is no standard method for estimating biomass in this vegetation type. In an attempt to develop a non-destructive field method for estimating biomass in Baccharisdominated communities, we compared three indirect measures including crown canopy height...
