Impact of different shade coffee management scenarios, on a population of <i>Oncidium poikilostalix</i> (Orchidaceae), in Soconusco, Chiapas, Mexico

<p><b><i>Background</i></b>: Understanding the effect of perturbation, be it natural or anthropogenic, on the demography and dynamics of the plant populations can help conservation management planning.</p> <p><b><i>Aims</i></b>: We assessed the impacts of management of a shade coffee plantation on a population of <i>Oncidium poikilostalix</i> (Orchidaceae).</p> <p><b><i>Methods</i></b>: We studied in a coffee (<i>Coffea arabica</i>) agroecosystem the impact of the current traditional management [T] and two hypothetical epiphyte control management scenarios (intense ‘desmusgue’ [ID] and moderate ‘desmusgue’ [MD]), on the only known Mexican population of <i>O</i>. <i>poikilostalix</i>. Based on 3 years of field demographics data, the population dynamics of the orchid were projected using T, ID and MD scenarios for 20 years into the future.</p> <p><b><i>Results</i></b>: Under the current management T, the population of <i>O. poikilostalix</i> was projected to grow continuously (λ = 1.102). Conversely, under management ID, the loss of individuals would lead to a sustained population decline (λ = 0.843); in the case of MD, the population would decline more slowly with the population growth rate tending towards equilibrium (λ = 0.966).</p> <p><b><i>Conclusions</i></b>: The changes in the management of coffee plantations that have become common throughout the south-east of Mexico represent a threat to the survival of the only population of <i>O. poikilostalix</i> in Mexico, and likely threaten other epiphytic species.</p

Correlation between the site chronologies of Aleppo pine and climate; monthly, seasonal, and annual precipitation and temperature from September of previous year (Sep-1) to December (Dec) of the current year (top).

<p>Only significant values are shown (p<0.05). Box plot showing the variability of correlation coefficients across the chronology network. The central horizontal lines indicate the median values, boxes enclose the central two quartiles, whiskers indicate the 10th and the 90th percentiles and the dots represent the full range of correlation coefficients. Dark and light grey areas indicate significance levels at 99 and 95%, respectively.</p
