Leaf Anatomy and C02 Recycling During Crassulacean Acid Metabolism in Twelve Epiphytic Species of Tillandsia (Bromeliaceae)

LOESCHEN,* CRAIG E. MARTIN,' * MARIAN SMITH,t AND SUZANNE L. EDERf •Department of Botany, University of Kansas, Lawrence, Kansas 66045-2106; and t Department of Biological Sciences, Southern Illinois University, Edwardsville, Illinois 62026-1651 The relationship between leaf anatomy, specifically the percent of leaf volume occupied by water- storage parenchyma (hydrenchyma), and the contribution of respiratory C02 during Crassulacean acid metabolism (CAM) was investigated in 12 epiphytic species of Tillandsia. It has been postulated that the hydrenchyma, which contributes to C02 exchange through respiration only, may be causally related to the recently observed phenomenon of C02 recycling during CAM. Among the 12 species of Tillandsia, leaves of T. usneoides and T. bergeri exhibited 0% hydrenchyma, while the hydrenchyma in the other species ranged from 2.9% to 53% of leaf cross-sectional area. Diurnal malate fluctuation and nighttime atmospheric C02 uptake were measured in at least four individuals of each species. A significant excess of diurnal malate fluctuation as compared with atmospheric C02 absorbed overnight was observed only in T. schiedeana. This species had an intermediate proportion (30%) of hydrenchyma in its leaves. Results of this study do not support the hypothesis that C02 recycling during CAM may reflect respiratory contributions of C02 from the tissue hydrenchyma.

Bromeliaceae) Species from Peru

GOUDA1 & RICARDO FERNÁNDEZ G.2 1Botanic Gardens, University of Utrecht (U), Budapestlaan 17, P.O.Box 80162, 3584 HD Utrecht, Netherlands. E-mail: [email protected] 2Universidad Nacional Mayor de San Marcos (USM), Museo de Historia Natural, Casilla 14-0434, Lima 14, Peru. Abstract A new species of Pitcairnia subgenus Pepinia (Pitcairnioideae) is described and illustrated here. Pitcairnia floresii sp. nov. has been found in the Department San Martín of Peru and is locally abundant. Key words: Flora of Peru, Pepinia, taxonomy Introduction This remarkable new Pitcairnia species with linear-lanceolate leaf blades and its red inflorescence with bright yellow flowers is rather common in the Central Huallaga River Valley area. The famous collector Richard Spruce was in this area in 1855 (León et al. 2003: 112), but as far as known no specimen of this species was preserved, nor was it collected afterwards. Another Pitcairnia, P. calatheoides Smith (1937: 24) has been described from the very same area, but is not closely related. The latter species has very long petiolate oblanceolate leaf blades and large orange petals. Mr. Alberto Flores, a farmer from Pucacaca, brought this beautiful species to our attention. From our study of Bromeliaceae of Peru several new species were recently described (Gouda & Manzanares 2008, Gouda 2012). The descriptive terminology of Scharf & Gouda (2008) is followed here.

Multi-National Conservation of Alligator Lizards
MULTI-NATIONAL CONSERVATION OF ALLIGATOR LIZARDS: APPLIED SOCIOECOLOGICAL LESSONS FROM A FLAGSHIP GROUP by ADAM G. CLAUSE (Under the Direction of John Maerz) ABSTRACT The Anthropocene is defined by unprecedented human influence on the biosphere. Integrative conservation recognizes this inextricable coupling of human and natural systems, and mobilizes multiple epistemologies to seek equitable, enduring solutions to complex socioecological issues. Although a central motivation of global conservation practice is to protect at-risk species, such organisms may be the subject of competing social perspectives that can impede robust interventions. Furthermore, imperiled species are often chronically understudied, which prevents the immediate application of data-driven quantitative modeling approaches in conservation decision making. Instead, real-world management goals are regularly prioritized on the basis of expert opinion. Here, I explore how an organismal natural history perspective, when grounded in a critique of established human judgements, can help resolve socioecological conflicts and contextualize perceived threats related to threatened species conservation and policy development. To achieve this, I leverage a multi-national system anchored by a diverse, enigmatic, and often endangered New World clade: alligator lizards. Using a threat analysis and status assessment, I show that one recent petition to list a California alligator lizard, Elgaria panamintina, under the US Endangered Species Act often contradicts the best available science. -
