Tests of an additive harvest mortality model for northern bobwhite Colinus virginianus harvest management in Texas, USA

Wildlife Biology, Volume 19, Issue 1, Page 12-18, March 2013., 2013
We evaluated the application of using an additive harvest mortality model (AHMM) as a harvest management strategy for northern bobwhites Colinus virginianus during the 2007/08 and 2008/09 hunting seasons in two ecoregions of Texas: the Rolling Plains (RP) and the South Texas Plains (STP). We collected field data on three study sites/ecoregion (of 400‐1,

Exergetic Model of Secondary Successions for Plant Communities in Arid Chaco (Argentina)

International Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013
Ecosystems are open systems where energy fluxes produce modifications over plant communities. According to the state and transition model, plant formations are defined by changes in natural conditions and disturbs. Based on these changes, it is possible to define vectors that show the tendencies of the communities towards other states.

Population dynamics, survival, and movements of Texas tortoises in a national park in southern Texas

The Journal of Wildlife Management, Volume 90, Issue 4, May 2026.
Texas tortoise abundance in a small national park in South Texas, USA, declined by >25%, from an estimated 273 tortoises in 2014 to 204 tortoises in 2024. The severity of the decline varied across survey units, but abundance remained highest in areas having greater canopy cover and experiencing less invasion by Guinea grass.

The role of competition in moderating plant–soil feedback for restoring ecosystems invaded by Brazilian peppertree (Schinus terebinthifolia Raddi)

Restoration Ecology, Volume 33, Issue 8, November 2025.
Abstract Introduction Ecosystem restoration requires the management of invasive plants due to the harmful effects they have on both above‐ and belowground ecosystem processes. Belowground soil modifications by invasive plants, particularly those driven by plant–soil feedbacks (PSFs), are thought to significantly influence an invader's success by ...

A Phytogeographical Classification of the North American Pacific Coast Based on Climate, Vegetation and a Floristic Analysis of Vascular Plants

Journal of Botany, Volume 2009, Issue 1, 2009., 2009
This study was designed to explore floristic variation along the Pacific coast from Cook Inlet, Alaska, to the southern tip of Baja California, Mexico. Data corresponding to 965 phytosociological relevés (including 686 vascular plants) obtained by sampling 279 coastal sites were examined.

NESTING AND SURVIVAL OF RIO GRANDE TURKEYS IN NORTHCENTRAL TEXAS

Wildlife Society Bulletin, Volume 2000, Issue S1, Page 85-91, January 2000., 2000
Abstract: We studied survival and habitat use of female Rio Grande turkeys (Meleagris gallopavo intermedia) during the nesting period in the Rolling Plains and Cross Timbers ecotone of northcentral Texas. Mortalities occurred during movement from winter roosts and during nesting.

Understanding an ecological tug of war: Disentangling competition between native and domesticated ungulates

Ecosphere, Volume 15, Issue 4, April 2024.
Abstract Competition is a complex ecological process involving individual and community interactions at ecological and evolutionary time scales. Individuals within and between species can compete through two mechanisms: exploitative and interference competition. These mechanisms often co‐occur, making it difficult to develop a mechanistic understanding
