Baiomys taylori and Sigmodon hispidus were the most abundant rodent species across all sections before the burn, with overall relative abundances (across all 3 sections) of 5.85 and 4.99 captures/100 trapnights, respectively (Fig.
We provided supplemental food to test hypotheses about the effects of food abundance and social dominance on population dynamics of Sigmodon hispidus.
(1975) mentioned the presence of the rodents Neotoma and Sigmodon collected near the town of Jocotopec; Peters (1951) identified remains of capybara, which he assigned to the extant species Hydrochoerus magnus, which later Mones (1991) identified as Neochoerus aesopi.
Sigmodon hispidus is a known reservoir of multiple hantaviruses (Rollin et al.
We tested two predictions derived from our model of southwestern rodent habitat relationships (Jones et al., 2003): (1) short term results of the fire would include a decline in cricetid versus heteromyid rodents due to loss of ground cover, especially on ungrazed sites; (2) recovery of populations of the cricetid genera Baiomys, Reithrodontomys and Sigmodon in ungrazed areas, coupled with declines in numbers of heteromyids in the genera Chaetodipus and Perognathus, would follow postfire vegetative regrowth.
Estudios filogeneticos indican que miembros del genero Sigmodon (Familia: Cricetidae) comunmente conocidos como "roedores algodoneros", constituyen el grupo mas ancestral de los Sigmodontinos, subfamilia que incluye a todas las especies de roedores de Suramerica y algunas de Centro y Norteamerica (Smith & Patton 1999, D'Elia 2003, Musser & Carlenton 2005).
Los 84 ejemplares de roedores se agrupan en 9 especies, 2 de la familia Heteromyidae: Heteromys pictus (9; 10.71%) y Heteromys spectabilis (5, 5.95%); y 7 de la familia Muridae: Baiomys musculus (14; 16.67%), Nyctomys sumichrasti (3, 3.57%), Oryzomys couesi (42, 50.0%), Oryzomys melanotis (1, 1.19%), Osgoodomys banderanus (1, 1.19%), Reithrodontomys fulvescens (4, 4.76%) y Sigmodon mascotensis (5, 5.95%) (Fig.
Prey item data indicate a diet predominately of mammals (primarily rodents of the genera Sigmodon and Peromyscus), but amphibians, a reptile, and birds were also consumed.
The three most common species in the small-mammal community are cotton rats (Sigmodon hispidus), prairie voles (Microtus ochrogaster), and deer mice (Peromyscus maniculatus), which collectively comprise nearly 95% of the total trap records from the site (J.
In Florida, a new but related virus (recently named Black Creek Canal virus [BCCV]) isolated from Sigmodon hispidus (cotton rat) is genetically distinct from MCV (4) and from sequences demonstrated by RT-PCR in lung tissues from a person who died of HPS in Louisiana (5).
Eight of the species we documented are endemic to Mexico including one didelphimorph (Tlacuatzin canescens), four rodents (Hodomys alleni, Osgoodomys banderanus, Peromyscus melanophrys, Sigmodon mascotensis), two bats (Glossophaga morenoi, Artibeus hirsutus), and one lagomorph (Sylvilagus cunicularius).
